THE SALVAGE OPERATION - 1947 to 1949
The recovery of the PLUTO pipeline
was the mother of all salvage operations! - dangerous, arduous and
huge! There were 21 pipelines stretching across the English Channel
and after two years almost 800 miles were recovered for recycling.
With the cessation of hostilities in Europe the cable laying ship I was serving on, HMS Latimer, was decommissioned. It had been involved in the laying of the P.L.U.T.O. petrol pipelines across the English Channel. This was a time of great upheaval and change as wartime conditions gave way to peace. I was presented with two options; remain in the service and be drafted to the war still raging in the Far East or take demobilisation. At the age of 32 my only seafaring qualification was a 1st mate's foreign going certificate of competency so I opted for demobilisation and a period of study for my Masters Ticket at the University of Southampton's School of Navigation. I then considered how best to fill in the few months before the course started.
We had little financial security as was the norm in those days for married ex-servicemen with young families. We had just enough money to cover our expenses while I was at University so the need for a full-time, if short-term, job was obvious and I soon found myself labouring at a Nuffield's metal reclamation centre some 25 miles from home. There were 15 hands, all ex-servicemen, under a civilian foreman. I was the only seaman, the rest being ex parachute regiment and Royal Marine Commandos. Our uncomplicated task was to segregate the various metals in a central dumping area but I was happy and carefree after the discipline and rigours of service life and I greatly enjoyed the inter-service banter and comradeship.
Earlier than expected I received confirmation of my University place and accommodation. Handing in my notice was however not entirely straightforward since the job was subject to the 'Essential Works Order Agreement' (E.W.O.A.). This legislation controlled the movement of labour for certain occupations considered crucial to the country's recovery. Fortunately the foreman and managers were very sympathetic and they contrived to circumvent the strict rules of the E.W.O.A. by declaring my job redundant. No doubt my job was filled after a suitable passage of time!
Our finances were still precarious but with careful budgeting we could fund my three months course followed by one week for the exams. Having sacrificed so much as a family, and having put in so much physical effort to accrue the funds we needed, I had the strongest of motives to get stuck in to my studies!!
The examinations consisted of seven written papers; Practical Navigation - 3 hours, Meteorology - 2 hours, Ship Construction & Stability - 3 hours, English - 2 hours, Ship’s Business - 2 hours, Magnetic Compass - 2 hours, Engineering Knowledge - 3 hours and Orals for Seamanship. The latter gave the examiners an opportunity to cover any perceived weaknesses in the written work and Signals which included Morse, Semaphore and the International code of signals. It was of unspecified duration but felt like a lifetime to me!
I was given the result of the oral part of the examination right away followed a week later by the results of the written papers. All subjects were "passed" and the sense of relief in our household was palpable....and we still had £17 in the fighting fund. We had made sacrifices and now there was time and money so the following Monday we were enjoying ourselves on the beach at Saltburn-by-the-Sea in North Yorkshire. The carefree abandon was not to last! My sister-in-law arrived with a telegram offering me command of the cable-ship Empire Ridley with a salary of £80 per month - £960 a year. This was untold wealth in 1946 so with little hesitation I wired back 'Provisionally accept please send further details'.
I learned later that my old commanding officer from the Latimer, Commander H Treby-Heale, R.D., R.N.R., had recommended me to the ship-owners when he declined the job on account of his age. The reference he wrote would have got me into heaven!My Appointment
The next day I received a telegram with full details of the appointment and early on the Wednesday I was on the train bound for Southampton. I met my boss and employer, Managing Director and Owner Captain J. O. Ingram of Marine Contractors Limited. In addition to owning the salvage firm he was also Chief Salvage Officer to the Ministry of Supply.
Captain Ingram explained the terms of the forthcoming salvage operation but I needed no explanation about the technicalities since I had an intimate knowledge of P.L.U.T.O. from my pipe-laying days in 1944. Four vessels were to be involved all under the control of Captain Ingram from the his Southampton Office viz.,
I stayed the night in the Dolphin Hotel at Southampton and next morning set off with Captain Doyle for Maldon and the river Backwater where both Ridley and Taw were 'laid up'. Little did we suspect what we would find there!
I'll never understand how I came to harbour the notion that I was returning to my late 'spick and span' HMS Latimer. Empire Ridley, stripped of all her Royal Naval accoutrements, was a depressing sight. She had lain unattended since decommissioning about 12 months earlier, was thick with dirt, rusty and generally derelict. Those were my first impressions and worse was to follow - she was infested with rats! No matter what I opened, cabin, locker, hold or engine room a myriad of little bright eyes shone out of the gloom. The vermin made no attempt whatsoever to run away but menacingly held their ground. In the amidships accommodation the timber under the brass door sills was eaten away leaving the brass strips unsupported. Cabin furniture was also destroyed. The situation left me in no doubt as to what my first priorities had to be. After several weeks 'deratization' by the Port Health Authorities, a thorough cleaning by local ship cleaners, and refurbishment, we were ready to live on board. It had been an unpromising start to my new command!
Crewing was also something of a problem. I had intended to immediately sign a full crew of 120 including the cable hands. However on advice about the suitability of labour in the local employment pool I decided to engage only a steaming crew for our passage to Southampton. We eventually departed from the River Blackwater and set course towards Southampton in fine, calm, clear weather. We signalled our owners details of our departure time and ETA (estimated time of arrival) at the Nab Tower. The calculations were based on a speed of 11 knots which was the cruising speed of the ship when she was in R.N. hands as HMS Latimer.
The passage was a nightmare! We rarely exceeded a speed of 6 knots in the most favourable of conditions with an average of 4 as adverse tides reduced progress to only 2 knots. We were forced to anchor in Dungeness East Roads in order to wait for suitable tidal conditions to round Dungeness Point and gain an offing from the coast. The engine room personnel were unable to raise a full head of steam but could not explain why. I suspected clouded judgement caused by excessive intake of alcohol. Learning from experience on leaving Dungeness East Roads we carefully calculated the next stage of our journey based on the actual performance to carry us up to Netley Pilot Station where pilot and tugs would be waiting to take us onward to No 102 berth in the new docks. Despite my worst fears we arrived there safely and paid off the steaming crew. They left, as they had arrived, in a blaze of alcoholic glory! Our new Chief Engineer identified the problem - the steaming crew had fed salt water direct to the boilers when it should have been desalinated by the engine room condenser. We were fortunate that the furnace crowns did not collapse as a result of hot spots caused by salt deposits.
Recruiting a crew at Southampton went well. The company, through Captain Ingram’s association with another local salvage organisation, were able to recruit a full engine room complement of first class hands, whilst through the School of Navigation, I obtained the necessary quality deck officers. The ship’s crew were obtained from the local shipping pool and the 60 cable hands selected, by interview, from ex-servicemen from the Army, Navy and Marines. We were spoiled for choice and ended up with a first rate ship’s company. Meanwhile, work at berth 102 was proceeding apace with the construction of a massive tubular steel scaffolding structure designed for discharging, coiling, and cutting up of the salvaged H.A.I.S. linesPipeline disposition on the Seabed
When the pipelines were laid there was already a desperate need for petrol to fuel the advancing Allied forces. The order of the day was therefore to commission the fuel lines as quickly as possible (see map opposite). Little or no thought was given to easing future salvage operations so it was not unusual for one line to be laid on top of others producing something of a tangle on the seabed. Number 1 and 2 H.A.I.S. lines, laid from conventional cable-ships, did have a reasonable separation within the two mile wide swept channel but number 1 and 2 H.A.M.E.L. lines were laid from the huge unwieldy floating 'CONUN' drums towed by the tugs of the HM Rescue Force (see below). This was a difficult operation with strong channel tides causing some deviation from the intended straight course. This resulted in the flexible H.A.I.S. lines being overlaid with the steel H.A.M.E.L. lines on numerous occasions.
The problem of fouling the over-riding lines was a challenge to be overcome. Between Dungeness and Boulogne, where there were 17 lines, the fouling problem was much greater in the early stages of operations when most lines were still on the seabed. The fouling situation improved as the number of pipes left on the seabed decreased. The salvage value was heavily in favour of the H.A.I.S. cables with their considerable lead content and for this reason they were given priority for recovery.
Thursday September 12 1946. Seaborne operations got underway: Tigness to work on the shore-ends of the H.A.M.E.L. (Steel) pipes in Sandown Bay on the Isle of Wight; Empire Taw to commence work recovering the 21 H.A.I.S. (Lead) pipelines between Lepe on the UK mainland and Gurnard on the Isle of Wight, each line being some 5000 yards in length; Empire Ridley to proceed to Sandown Bay where Redeemer, aided by her divers, would locate, cut and lift the seaward end of number one H.A.I.S. line. This done the Empire Ridley was gently brought alongside her and the pipeline end transferred by way of Ridley’s main forward cable hauling gear. The change-over occupied about one hour and twenty minutes before the cable end was inboard and secured in No.1 cable tank. At this juncture the recovery work commenced employing 20 cable hands coiling down as the huge winch drum steadily hauled the line inboard from the seabed.
The start of operations attracted considerable press interest, and the inventor of H.A.I.S. (Mr Hartley) was on board as an observer. The weather was fine, calm and clear - ideal conditions for everyone - the hands, the cameramen and the VIPs.
We worked continuous shifts until 1400 hours on Friday September 13 (note the date) when, owing to main engine defects requiring a complete shut-down, we came to a grinding halt. We rode to cable throughout the rest of the day and all night until 0514 hours on the Saturday morning, when work resumed. By noon we had recovered 7.5 miles of H.A.I.S. line.
About this time the weather worsened with a force 6 south-westerly wind. There was a rough sea and heavy swell when the wind was over the tide. Around 1700 hours the pipe came in leaking and spurting petrol in all directions. This was a surprise since we had been assured that the lines were petrol free having been pumped through with water. It took an hour or so to cut cable and plug the leaks before we were able to continue heaving in.
At midnight the weather conditions increased to gale force 7-8 with a high sea and heavy swell. Ridley rolled and pitched and shipped some water. Sunday at 0145 the pipeline parted and a number 9 crash buoy was released to mark our position. We had recovered 12.05 miles of cable. Conditions were quite impossible for grappling to recover the cable so we set course for the Saint Helens anchorage. I had hoped that by continuing to slowly pick up cable that we could have ridden out the storm, but I knew then (learning the hard way) that our policy must be to cut and buoy off in conditions of force 6 winds or greater.
Come daylight in the anchorage we examined the bow rollers and found several bent and fractured with numerous protruding sharp edges which were likely to have contributed to the cable breaking. We decided, with the agreement of Head Office, to proceed into Southampton and effect repairs. These were completed by the early morning of Saturday September 21 and at 0800 hours we sailed for Sandown Bay to pick up the end of No 2 H.A.I.S. line.
On arrival we found Redeemer had not been able to work her divers due to bad weather and so we went to anchorage. The bad weather continued for several days and no diving was practicable so, at 0730 hours on Tuesday 24th I decided to make a grapnel run for the bight of No 2 H.A.I.S. We made our first attempt at around 1025 hours and at 1047 hooked the cable, raised the bight to the bow rollers, 'stoppered' off each side of the spearpoint grapnel and cut the cable bight. We then buoyed off the shore-ward side for the shore-end vessels to pick up and hauled the seaward side inboard. By 1440 hours we commenced coiling in, wind force 3 and W.S.W. Remember there's a list of nautical terms if you're a land lubber!
At 1125 next morning the 25th September we ran foul on one of the steel pipelines. It took about an hour to work clear only to run foul again after about 75 minutes. This was a difficult tangle and we worked all night before succeeding at around 0830 hours on 26th. By noon we managed to recover some 7.5 miles of No. 2 H.A.I.S. making a total of 19.75 miles on board. Throughout the day we ran foul of the steel lines three times, losing some 4 hours of cable recovery time. There were unhappy faces in the cable tank as the coiling crew were on bonus.
On the 27th September we ran foul of the steel pipes on four occasions losing almost 17 hours of progress and on the 28th, just before 0600 hours, we ran foul again. This time it turned out to be on No 1 H.A.I.S. that we had lost earlier. This was a tangle that took some considerable time to clear and then only partially. While endeavouring to secure and buoy the No 1 cable snapped. The seaward end, again unmarked, was lost but to the landward end, we succeeded in attaching a marker buoy, and by 1620 work resumed on the salvage of No 2 H.A.I.S. At 1835 hours we had 25 miles of cable in the cable tank and in order to keep the ship in trim we changed to stowing in the empty tank.
All went well until around noon on the 29th September when we ran foul again - more very hard work with no tangible rewards in the form of salvage. Eventually, at about 1300 hours on the following day we managed to raise the troublesome object. It turned out to be No1 H.A.I.S. again. By now the pattern of the salvage operation was apparent - foul, clear, foul, clear, etc., until Friday October 4th when the weather once again turned bad. At 0500 hours we buoyed off in position 50o-12.5’N – 1o-21’W and returned to Saint Helen’s Roads to anchor. We had a total of 43 miles of cable on board.
This was in the main a mundane salvage operation but there were moments of excitement and danger which are detailed later. By the end of October Empire Ridley had 87.5 miles of H.A.I.S. cable on board while Empire Taw and Empire Tigness both had quantities of H.A.I.S. and H.A.M.E.L. Captain Ingram decided to bring all three craft in to 102 berth Southampton New Docks to discharge their cargo during the worst of the winter weather period - November through to February inclusive. Much had been learned during these first seven weeks of salvage which would be applied in future salvage work. The Ridley's cable hands were employed on discharging and coiling duties while the ship’s crews were employed carrying out routine care and maintenance.
Winter Shore Operations - Recycling of Materials
Figure I shows the discharged coils (not yet available). The numerous cable ends protruding from the coils give a good indication of the number of times the lines had to be cut and plugged when, for one reason or another, they had become fouled on the seabed. When the coiling to shore was completed our next task was to ensure the lines were cleared of petrol prior to being passed through the guillotine which cut the pipe into lengths to fit easily into the railways wagons waiting below the cutting machine loading roller-ramp.
In turn each length in the coil was connected to a water supply at one end, whilst the other end was fitted with a flexible pipe leading direct into a mobile petrol bowser tanker. Water was then turned on pushing the petrol from pipeline into the bowser until the operator reported only water coming through. The contaminated petrol was then taken by road to a special Ministry depot for separation treatment to obtain clean fuel. By this process 66,000 gallons of good fuel was recovered.
The cleansed cable was passed over the hauling gear on the discharging gantry and then, via the cable transporter gear, to a roller arrangement. This led into a heavy duty guillotine which cut the cable into exact lengths to fit the railway wagons. This done the lengths fell to a roller ramp which delivered them to the waiting rail-side wagons for onward journey to Swansea. There a Ministry of Supply depot was established to provide work at an unemployment black-spot. Each length was broken down in the first place into lead, armour wire, steel pressure tapes and even the outermost layer of string-like jute yarn 'serving.' The reclamation process comprised the following operations;
On the morning of Feb 21 1947 we recommenced the seaborne salvage work but fog and snow forced us to anchor in the Man of War anchorage off Spithead. On the 22nd we moved anchorage to St. Helens Roadstead off the Isle of Wight to wait favourable weather conditions. We finally started the second phase of the salvage operation on the 24th February 1947 by picking up our marker buoy in a position 179.5o degrees 15.3 miles from St. Catherine’s Point. In general proceedings followed those of our earlier operation - recovery, fouling, recovery, fouling, cutting, buoying off and running for shelter. Each time we cut a fouling steel pipe we buoyed off both ends so that Tigness and Wrangler could recover the pipes before the buoys were lost to passing ships. On one occasion all our buoys were in use or in transit so we used 40 gallon oil drums as an interim measure until MFV Redeemer replenished our stock.
Our makeshift marker buoys had a tendency to 'run under' due to strong tides and the weight of the mooring wire. Under these conditions they collapsed under the pressure of water, lost buoyancy and disappeared below the waves never to be seen again! Working in fairly deep water required the use of long lengths of heavy mooring wire so two, or even three, oil drums were needed to ensure positive buoyancy under all conditions. The standard No 4 cable marker buoys had bulkheads to prevent collapse, but the No 9 type, often used as steel markers, had no bulkheads and also ran under from time to time. However they were much stronger than oil drums and only on rare occasions failed through metal collapse.
By April 12th 1947 53.2 miles of H.A.I.S. cable had been recovered from the Cherbourg to Isle of Wight circuits number 1 and 2, making a total recovered, by Empire Ridley, of 140.7 out of about 144 miles originally installed. Our job done in that area we received instructions to make for the Dungeness/Boulogne area to continue salvage duties until we were fully loaded. Empire Taw, Tigness and Wrangler, already working in that area, were experiencing serious problems due to cable fouling made worse by inaccurate plots of the positions of the pipelines on the seabed. This was a matter of some concern to the company since very little cable was being salvaged during these periods of disruption. Crudely expressed they were spending without earning - a state of affairs no company can sustain over a prolonged period.
Empire Ridley arrived off Dungeness at 4am on April 13th. It was a misty morning and only the Dungeness high light was available for compass bearings so we decided to wait for daylight before dropping our marker buoy to signal grappling operations. I was confident of our position to pick up the No 17 line which was the final H.A.I.S. cable laid from HMS Sandcroft. At 0720 hours we dropped a No. 9 marker buoy in position Dungeness High Light bearing 306o at a distance of 3.2 miles. We then awaited the turn of the tide to allow us to make a correct line of approach for the initial grapnel run.
At 0923 hours we let go the spearpoint five prong grapnel and made our first pass by 0940. This completed we stopped and hove up to find the grapnel empty. As is often the case with fishing we had felt a tug on the line during the run but the cable had gone slack again - a possible near miss. By 1010 hours we were back in position and commenced our second run at a slightly reduced speed. At 1030 hours we made a contact and commenced heaving in the heavy wire. At 1047 hours the grapnel broke surface with a single H.A.I.S. pipe hooked on two prongs. It was possible to identify the ship that laid the pipe from the type of bitumen compound 'lutin' used and the length of the lay of the armour wires. Confidence was high that we had located the pipeline we sought and we cut the bight after first holding each side of the cable in stoppers from the forecastle head.
The shore leading leg showed very little tension an indication that it was a 'short end'. The seaward leading leg was taken to the starboard main winch drum and hauled in until the end could be secured in the cable tank. Our suspicions about the shore leading leg were confirmed when 100 yards of pipeline were easily dragged home. There were signs that it had been cut by hacksaw and after stripping down a short piece the manufacturers name tape confirmed our earlier armour and lutin check. We had indeed found our target cable.
The Managing Director of Marine Contractors was a very keen fox hunting man and a member of his local hunt. We signalled our success and imminent progress in the Dungeness Boulogne area with the signal "Yoikes Tallyo" and started to haul away towards France. This was the last of the pipelines to be laid down so was free of snags and it was the only line salvaged that didn’t run foul of other lines. However off Boulogne the pipeline ran into the Bassure De Baas sand bank. We hauled bar tight and used the rise of the bows on the swell for increased lift but in the end we were obliged to cut, proceed to the French side of the sand bank, re-grapple and lift the line from the Boulogne shore. We followed similar procedures until once more running foul in the sand and again abandoning the cables across the width of the sandbar. In due course we found that some of the pipelines had become so deeply embedded in the sand that our hauling gear could not pull them out despite our best efforts.
We experienced a similar problem close to a position south of the ridge of Le Colbart Bank in mid channel. On this occasion the pipeline was not so deeply embedded in the sand and mud and the procedure worked well allowing us to recover all the pipeline from that locality. However it resulted in a mile of very slow progress but this was, nonetheless, infinitely better than having to cut and re-drag with the high risk of hooking the wrong cable in the new location.
We still had storage space onboard for pipeline so we moved back to the English side to find a good target position for an original hooking of No 11 cable. This was the penultimate H.A.I.S. line laid by HMS Sandcroft. From the known order the pipelines were laid it was likely that the number 11 H.A.I.S. would be fouled by steel H.A.M.E.L. pipes numbered 12 to 16. However once more good intelligence from the laying operation proved its value. Working as before on a single bearing and sextant angle on Dungeness High Light and using a No. 9 buoy with mushroom anchor mooring for a data marker, we found our target on the third grapnel drive. It was a good start but as expected No 11 ran foul of the steel pipelines on numerous occasions. But on one particular night we were due for a big surprise!
Around 2am an "all stop" whistle signal was heard from the bow cable look-out man. To our amazement right up under the bow rollers, and just awash, was a German fighter aircraft minus its cockpit cowling. The cable was snagged on the port wing and had torn half way through as far as the main strut of the wing. At first we were tempted to salvage the plane but the only derrick capable of lifting the weight was set up and rigged for other uses. Un-rigging and setting up the necessary double purchase gear was a fairly lengthy operation but there were other reasons for caution too - there was no convenient stowage space available and we had no idea of the quantity and state of any munitions still within the fuselage and wings - an unacceptable fire risk with petrol spillages from the recovered pipes within our cable tank. That decided we had to return it safely to the deep.
We hauled in cable and draw the fouled port wing right up under the bow rollers in the hope that the rest of the plane would break off and fall away under its own weight. It worked a treat. With scarcely a sound the main wing beam broke and the plane slid back to Davy Jones’ Locker. We were once again free to get on with money making salvage work. For reasons of their own Head Office endorsed our decision by noting that "the value of the salvaged plane was very low and its nuisance value in Southampton Docks would have been correspondingly very high".
The completion of the salvage of this second HMS Sandcroft laid cable brought our cargo to 102.2 miles of 3" H.A.I.S. cable - just a little over the design capacity of our two cable storage tanks. We left the salvage site for Southampton to discharge our cargo leaving Empire Taw working on the shore end H.A.I.S. lines off Dungeness.
On a number of occasions when trying to clear a fouled cable we hove up our spearpoint grapnel to find moored mine wire in the flukes. When there was weight on each side it was prudent to assume we had lifted both the mine and its plummet weight off the seabed. In these circumstances it was not a good idea to cut and let go the wire for fear of explosion! Instead a wire 'preventer' was lowered from each side of the ship’s bows and, with seamen working from Bosun’s chairs, the preventers were clamped to the mine wire almost at water level, one each side of the bight in the grapnel fluke. The stoppers were hove tight and made fast to the forecastle head bollards and then, with the hands back inboard, the grapnel was lowered to clear the mine wire bight before being taken inboard out of the way. Next the two stopper wires were slacked away gently at the same rate until the weight came off indicating mine and plummet weight were back on the seabed. The stopper wires were then cut and allowed to sink to the bottom.
Our caution and respect were borne out of an understanding of the mine's mechanism. Some moored minefields were designed to float just below the surface for a specified period after which they sank to the bottom. The casing of the mine was fitted with a soluble plug which after the set time would dissolve and allow water into the casing thus sinking the mine. With the weight removed from the plummet sinker the fail safe device would operate rendering the mine inert. However we were concerned that mines caught up in our gear had been reactivated. The fact you are reading this indicates we were very lucky or our justified fears were groundless… or perhaps the rabbits foot in my pocket was doing its job!
At other times fouling was caused by wreckage on the seabed. On more than one occasion the grapnel wire came bar tight and brought the winch to a grinding halt. Slacking back the wire and allowing the ship to fall back on the tide sometimes freed the grapnel but on other occasions we made the wire fast on the forecastle bollards and used the ship’s engines, ahead and astern, until we came free, shifted the wreckage or broke the grapnel prongs off! On one occasion we even broke the heavy duty 6 x 3 compound wire thus losing the grapnel. By the curse of Murphy’s law it was almost invariably during the hours of darkness that these various hold-ups occurred! As we gained experienced we could tell from the note of the hauling winch engines that we were running foul of the steel pipes. Gradually the normal operating note of the engines would be replaced by an increasingly higher pitched whine as the winches laboured under the extra weight of the steel pipes. By the time the H.A.I.S. pipe was hove inboard it would begin to twist and flatten on the bow rollers. It was time to start clearing operations.
There were dangers in the recovery of the H.A.I.S pipelines but the recovery of the H.A.M.E.L. steel pipes was in a different league! Having secured an end onto the deck the line was hauled aboard by means of a horizontal caterpillar machine on the fore-decks of Tigness and Wrangler. A system of rollers abaft of the hauling gear, and running the full length of the working decks, allowed the cable end to be taken as far aft as possible. Once in place the pipe was cut into suitable lengths and then transferred from the rollers to a stowage area on the working deck... and so the process would start all over again.
Each length of H.A.M.E.L. cable was cut just aft of the caterpillar by means of oxy-acetylene burners. However there were still pockets of petrol and/or gas at very frequent intervals and the hands were equipped with fire and flash proof gear against the numerous bursts of flame and gas flashes. Often petrol leaked from the pipes and despite our best efforts was not washed away from the decks. From time to time patches of fire occurred on board.
The decks were kept wet at all times by means pumping water from the ship's ballast tanks. There was also an additional hazard less threatening to the ship and its crew but quite spectacular in its own way. Sometimes petrol leaked whilst the pipe was still outboard and formed a film around the ships. Inevitably sparks from the burners caused the inflammable film to burst into flames. It was an uncanny sight as the fire around the ships passed clear on the tide and burned itself out astern. The crews of the two vessels seemed to treat the matter as just part of the job, nevertheless, whenever Empire Ridley was working in sight of either or both ships it became standard practice to call them on radio telephone to ensure all was well.
Finally figures 7 to 12 (not yet available) inclusive which follow illustrate some of the seaborne salvage work, sadly the quality of the pictures is not good, the originals being rather old and much handled photographs.
The general routine of the work was similar on both the H.A.I.S. and H.A.M.E.L. recovery ships - operating at sea during the period March to November and in port between November and March discharging, cutting and loading salvaged cable to railway wagons for onward transit to Swansea. By late 1949 a total of 478 miles of H.A.I.S. cable had been recovered from a total of about 482 miles laid, and around 300 miles of H.A.M.E.L. out of some 330 miles installed had been recovered. Salvage operations were concluded. In October 1949 all the cable landed at Southampton was cut up and delivered to Swansea and work commenced dismantling the site at 102 berth. The value of the salvaged material we were informed was considerably in excess of recovery costs. This no doubt provided the Ministry with a handsome profit as well as creating work for a few years in an unemployment black-spot.
The Empire Ridley was sold to Spanish owners, Empire Taw to the Irish Lighthouse Services, Tigness and Wrangler with Redeemer remained with Marine Contractors Limited to continue the company's marine salvage work. The crews of Ridley and Taw were paid off and dispersed almost all securing berths in various liners out of Southampton. I had the good fortune to get an immediate appointment as Marine Superintendent in Messrs Siemens Brothers of Woolwich, Submarine Cable Department. I had an excellent and effective crew and when we parted I had mixed feelings - glad we had successfully completed the project but sad to say goodbye to men I admired and respected
Even under normal operating conditions our work was fraught with danger as enormous forces were at play. These dangers increased dramatically when we were dealing with unknown objects, unexploded mines, fouled lines and petrol spillages. Despite the dangerous nature of the work, often undertaken in rough sea conditions, there were thankfully no serious casualties The successful completion of the salvage operation is a lasting testimony to the bravery, skill and dedication of the officers and men involved.
A Spearpoint Grapnel is essentially a huge 5 pronged spinner type fishing hook. Each prong is called a fluke. The Grapnel used in the recovery project weighed in at around 2 to 3 cwt and was attached to a powerful winch by a special rope.
The Cable Bite was that part of the pipeline, in the shape of a curve or loop, raised from the seabed by the Grapnel to the level of the ship's deck.
A Stoppers is short length of rope, wire or chain attached to a taut line or mooring rope to take the tension in the line or rope while it is, for example, made permanently fast on the ships deck.
A Bollard is a heavy duty solid metal post on a ship or dockside to which ropes or wires can be securely anchored.
Plummet Weights are heavy anchoring devices to hold sea-mines in position just below the surface, which would otherwise float on the surface. Under tension the mooring wire holds the mine's firing mechanism in the live position thus ensuring an explosion in the event of a ship colliding with it.

To many in WWII it seemed a preposterous idea - an undersea pipeline laid across the bed of the Channel to carry fuel to the Normandy beaches. It was carried out in absolute secrecy &, according to Eisenhower, it was "second in daring only to the artificial 'Mulberry' Harbours.' The extraordinary project, & the millions of gallons of fuel it carried, helped to ensure that the Allied armies could break out after D-Day. 126pp, photos, ills, maps).

(10/04) Dismantling of PLUTO in Greatstone, Kent. I observed the dismantling of PLUTO in 1947 from where I lived at the time... Greatstone. Although I was only 6 years old then, I remember the pioneer tracks being laid from the area adjacent to the "Jolly Fisherman". It was all in the local paper, so I think it should be possible to get something from local archives. Somebody painted on the rusting hulk of the main container "Stuck like Atlee". There must have been many hitches and hold-ups because some weeks later someone painted "Still stuck like Atlee" on the partially dismantled but still substantially complete container.
