Wreck diving on the "HAVEN"

At an impressive 300 meters long and 52 meters wide, the super oil tanker Milford Haven was one of the largest tankers of its time. But in April 1991, things took a tragic turn: After the ship had called at the port of Genoa and parts of the cargo had been unloaded, an explosion occurred that tore a gigantic hole in the ship's outer wall. During towing, the bow broke off and sank. After almost three days, the remaining 250 meters of the ship, including most of the upper deck, the superstructure and the stern, followed and have since lain at the bottom of the sea at a depth of 33 to 82 meters. The wreck offers breathtaking diving opportunities. The superstructure starts at a depth of 33 meters and extends to the upper deck at 55 meters. All levels can be dived and there are countless fascinating details to discover. Even after several dives, you still have a long way to go before you have seen everything. The various well-preserved rooms are particularly exciting - from the kitchen to the engine room. The preserved areas offer an unforgettable insight into the past of this mighty ship. From 24.04. to 01.05. we move into the Trimix area, where the dives become increasingly challenging and exciting. Especially for CCR divers, the "Haven" offers unforgettable adventures - from the workshop to the engine room, which is connected to a significant penetration and lies at a depth of 60 to 70 meters. It is worth taking the scooter with you to explore the break-off edge, where the bow has broken away from the rest of the ship. A tour around the superstructure also promises spectacular impressions, as does a trip past the explosion hole. If you would like to get an impression in advance, you are welcome to watch the video of our last tour in autumn 2024 on YouTube! This tour offers something for everyone: from experienced technical OC divers to CCR divers who want to go deep into the engine room - the Milford Haven is a must for every wreck lover!
