  • MMC Divers Undertake Isle of Wight Wreck Removal

    Cowes Divers MMC on the Isle of Wight assisted Cowes Harbour in the wreck removal of a privately owned house boat which sank in the river on its berth.

    A six man strong dive team in conjunction with Kingston Marine Services and Unique Seaflex worked together in order to reduce the catastrophic losses that the client had suffered when his home sank.


Client: Cowes Harbour Commission

Principle Contractor: Kingston Marine Services

IOW Divers MMC were appointed by Cowes Harbour Commission to undertake a survey to determine the best solution to raise the sunken houseboat Mv Malbuhay, which had sank on her mooring piles in Cowes river in approximately 5.0 Meters of water.

Unfortunately the underwater survey uncovered that the hull had been breached in too many places to enable the vessel to be safely left unattended without the aid of pumps and lift bags. A team were called together by Cowes Harbour Master, consisting of MMC Divers, Unique Seaflex, George Truckle Marine Surveyors and Kingston Marine Services. Kingston Marine Services placed an oil boom around the vessel to minimise any impact on the environment, this was monitored regularly by the Cowes Harbour patrol.

MMC Diving Services supplied a six man strong team and full surface supplied diving spread. The Diver attached two 3 ton parachute lift bags to the four inch prop shaft to raise the vessels stern off the seabed, which allowed just enough to position sets of spreader beams steels either side of the keel with two 5 ton lift bags attached to each set.

Due to the combined weight of the spreader beams and lift bags, which were made up on the surface, being unmanageable for an individual diver, the beams were dropped in the water at the stern on the flood tide and a 10 ton deck winch pulled them along the seabed into the tide until they were positioned as far forwards on the wreck as possible by the diver. The objective was to set up lifting bags as low to the keel as possible and as far forward to gain maximum lift, and then run hoses to a surface supplied compressor through a control manifold.

The diver then checked the full lift plan, and exited the water. All divers were clear of the water before any lifting took place. Once the vessel was afloat divers attached towing strops onto the vessel ready for handover to Kingston Marine Services who towed her to Kingston Marina for her removal.

"Cowes Harbour Commission, Kingston Marine Services and MMC divers are a well-proven combination. The wreck removal of the sunken MV on the river Medina this November is the latest in a succession of very successful projects."
