The tanker "PETRAGEN ONE" loaded with more than 24.000 tonnes of Naphtha exploded right next to the pier in Algeciras Bay, Spain. The wall of fire spread to the DWT tanker "CAMPONAVIA" loaded with 6.500 tons of petrol. The smaller tanker exploded and turned 90 degrees and droped under water. The 29.950 dwt tanker burned for days and destroyed several hundred meters of pier and associated pipelines.
To execute the job according to contract, divers had to seal numerous holes in up to 28 meters water depth. The wreck had to be cut into several parts. Lifts were performed with two salvage cranes of up to 2,000 tons. The stern part of M / T "PETRAGEN ONE" weighed about 5,000 tons. Countless damages were sealed at the stern part under water, so that part of the water could be pumped out for the necessary buoyancy to be transported with 2 cranes.
To eliminate the pier the 800-ton concrete blocks were removed with a grab, the pier base was blasted under water and cut with oxygen lances.
Only in the execution of this one order the full spectrum of salvage experts was used.
Underwater explosions, diving operations, use of mobile pumps, crane operations with gripper, lift of 2,000 tons, and removal of heavy wreckage and quay parts.
This salvage and wreck removal was only one of many, successfully carried out promptly and without environment pollution.
