March 6, 1987 (the salvage of the Herald of Free Enterprise)May 30, 2021
the sea took one hundred and ninety-three human lives you, if I spread my wings towards the morning or dwell in the ends of the sea even there and guide me, your right hand will sustain me if I say with certainty that darkness will cover me and night will completely envelop me without warning The Herald of
enterpriseshipwrecks near the Belgian coast on March 6,
1987the ferry owned by Townsend Thoresen has just set sail as a runner On board the ship there are 543 people and one hundred and forty-five vehicles weighing around 1,100 tons as part of the cargo the wreckage lies three-quarters of a mile north and says that the port of Braga just outside the Canal Street even before the
salvagecontract has been signed Engineers at Schmitt Tuck in Rotterdam are drawing up a rescue plan no other
salvagecompany can mobilize the necessary equipment and in such a short time as Schmitt tack does in close collaboration with the urs towing and rescue union of Antwerp the
enterpriseweighs 7,000 951 tons has a length total of 131 meters and a beam of more than 22 meters, with this knowledge of these and other details, a scale model of the ship is made, this is vital to be able to establish how the overturned remains can be successfully righted.
The lifting force for this operation will be provided by three grate legs on to tow barges with a total lifting and pulling capacity of more than 10,000 tonnes. Approximately half of the wreckage is visible above sea level during low tide depth. The water in this particular location is more than 11 meters the ship's hull plating appears to be intact with dents smelling of gases escaping from the ship's hold it is not known exactly what cargo the vehicles were carrying chemical experts come in the remains to determine the composition of the fumes do not find immediate dangerous circumstances it is difficult to determine the size of the overturned ship on which the stairs are now in a horizontal position a part of the cargo of the overturned trailers floats in the hold of the ship are taken Water samples in many parts of the ship will be examined for toxicity and radioactivity Silent evidence of a tragedy is everywhere with an ass of tragedy The international press arrives on the scene in great force to report the disaster Monsignor superintendent of rescue hands of the camp de Balan explains to journalists and authorities the method chosen by Schmitt to right the ship so that they can see here the 32 points that we designed during the weekend our bringing the Father to all of them at this moment we are so far away that the first um strong points have arrived good morning so you will start this afternoon at least with all the necessary preparations to solder those two points so that's the connection like As far as the ship is concerned, you, Elvis, have arrived, your welding equipment has arrived, we are learning now on our Teens rescue boat in Bergen and intend to leave within an hour or two, provided weather conditions remain good.
The men will work day and night. night 24 hours a day in the accident the first thing to do is well 32 strong points to which wire slings can be attached for the traction barges for the sake of the pool party 31 and 32 will be secured by means of 16 piles driven into the seabed these The piles are actually steel tubes used to transport liquefied gas, they have a diameter of 142 centimeters and a length of 30 meters before the driving of the piles can begin. piles, wire slings must be attached to the 16 piles with which the files will be driven. the cables connected to the seabed at a depth of approximately 1.7 meters in Salvage's history this is only the second time but piles have been used for this purpose the floating cutter legs Norma has been appointed for this work aboard the ship exactly The location of each pile is carefully verified with precise positioning equipment.
This is of utmost importance as there must be a proper distribution of the enormous power necessary to raise the
heraldof free enterprise. Each pile must withstand a force of 200 tons during the entire salvage operation. Water samples are taken. There appears to be no immediate danger with sudden drops in temperature due to icing. Working at Harold becomes a risky business. We will find the strength as much as possible. We will install overhangs on the main deck on the upper hill. Although the sea is calm and there is little wind, it is difficult to place the forty-foot-long cantilevers that sway violently.
Ten welders work day and night to fix these cantilevers. Exhaust pipes and scuppers in the hull plating should be sealed with concrete and wood plugs as they will be below the waterline once the wreck is back upright and then, due to bad weather, Welding of the cantilevers must be stopped, but on March 26, 20 days after the disaster, this work was completed. However, a dense fog forms at the welding and other activities continue. 10 reaction anchors weighing 15 tons each have arrived from Schmitt's rigging warehouses in Rotterdam. The rescue ship Schmitt Orca will set anchors to prevent the wreck from moving sideways.
Therefore, for reaction anchors, they will be installed around and under the agreement. from the ship with poor visibility the Schmitt Orca transports the reaction anchors one by one to the site, taking them under the rock without radar such a task would be impossible due to bad weather the positioning of the anchors takes five days to carry out this work Smit Orko is assisted by the salvage ship doula pulling the anchor cables under and around the wreck. The duello carries the anchor cable to the wreckage where it is secured to a strong point. The Schmitt Orca drops anchor after the cable has been tightened in the meantime.
Welding continues at the end, welding in construction required a total of 3,500 man-hours. Strong currents sometimes occur around the wreckage created by wind and tide, making salvage work difficult, especially diving operations, and the position of the ship is exposed to the scour effect of Sam, on 4 April, traction barges arrive on site. The pull cables already connected to the ship on the way over the deck will trigger the overhangs. We connect it to the 2p bodies by touching 31. It takes until the afternoon to connect the traction cables. the herald of the barges these steel cables have a diameter of more than 9 centimeters a total length of about 6 kilometers steel cable is finally used to save the ship and the stabilizer in a vertical position the 16 piles are now connected to the barges of traction with the cables, each cable measures 140 meters, the diameter is more than 9 centimeters, a shackle like this comes weighing more than 230 kilos, the day finally comes when all the wise men are united and the editorial staff of The Herald can begin a twin force of two to three at sea.
It is calm but the weather is going to worsen shortly according to the forecast it has been decided to start drafting operations in the early morning of April 7 the operation is controlled from the commander's cabin aboard the trawl barge Kharkiv 32 in the vicinity To the remains of the ship, the barges and three grating legs are in position to pull and hoist simultaneously, he made a plan for a scale model of the remains that would be used to record the progress of the writing. Well, I admit that the naked debt rigs in Tecla increase four and six. the lifting capacity of both plow legs up to four thousand tons to twenty begins the writing operation the weather conditions remain favorable the wind is hoarse from two to three gradually the pulling force of the traction barges increases to two thousand three hundred and twenty tons during the operation, yes, okay, Thomas, who can't find another look, okay, how was L and the normal one, but together, Roxane 300 fair, oh, okay, and Douglas is here, she looks wonderful, okay, Szechwan, the fastest and, in this, Alain is crazy, hey, look? the race the last class I will do it slowly but surely the ship is raised to its normal position the cutting legs Norma is freed as her contribution to the critical phase of construction is now open the red insignia appears above sea level a As the hours pass, the ship returns to the vertical position, meter by meter, the lifting capacity of the XI legs increases to two thousand six hundred and sixty tons.
Various objects float out of the damaged ferry. Yes, mud and sand are dragged to increase flotation. of the wreck after 10 hours the drafting operation reaches its final phase between 5:00 and 6:00 in the afternoon the list, which is continuously monitored on board the ship, is now reduced to about 5 degrees as soon as the herald is once again in a nearly upright position the salvages This time it was temporarily stopped to allow the authorities to inspect the interior of the ship in the cafeteria. Many passengers lost their lives. The recovery of the victims lasts until midnight and continues for the next few days, as steep lakes and barges hold the remains in position from the chaos that ensued.
On board the ship you can now see how quickly the tragedy occurred. Rob's lifeboats could not be lowered in time as recovery of the bodies was a primary concern. The drainage of the wreckage and its impermeability is delayed for days and suddenly there are strong winds that reached gale force on the night of April 12 and 13 gained strength 9 Wave 6 meters high / the wreckage at night the anchor and mooring cables break steep legs tack lift and board if six and one of the traction barges are freed According to records, the Herald of Free Enterprise is moving 60 meters to the east and 10 meters closer to shore.
The ship sinks three meters to the bottom of the sea. The list now exceeds 15 degrees to port. It takes almost a week to secure the wreckage in position before preparations can begin. Resume or refloat with wooden planks, you must first repair the windows and doors that have been broken during gales, at the same time installing and placing pumps throughout the ship when the pumps come into operation. 5,000 tons of water per hour are pumped from the wreckage during operation the shared legs help lift the ship and as stability is critical they also keep it upright each bow lift can develop a lifting capacity of 1200 tons the lifting slings lifting wire are now attached to the boat leading from port to starboard and the others from starboard to port thus equalizing the forces of both sides in the lower compartments of the boat the water level gradually drops Oh thanks later at half past ten the morning of April 27 the herald of freedom the company is again afloat the tugboats can now take the Cahaba zebra to the boat accompanied by boat legs that keep the remains stable and upright while the water pumping continues - beer now promised show compilations before times 20 after the Zeebrugge er breakwaters are passed at approximately a quarter past 11 after the wreck is moored in the outer harbor, cargo unloading and cleaning operations begin , the final phase of the operation is when the herald of free enterprise stops at a washing yard. achieved you you
