When Inverness-registered fishing vessel Rosebloom ran aground, north of Lerwick, recently, her fate hung in the balance with many factors that could take her to significant destruction. However, good weather, a good build and the intervention of Ocean Kinetics have seen her safely to port, where the full repairs can begin.
Perched on the submerged reef know as the Soldian, the stricken vessel sustained damage to her hull below the waterline as wind, wave and tide rocked her where she lay. A salvage team of Ocean Kinetics engineers were mobilised just hours after the grounding occurred and, once on site, they could assess the damage and make temporary repairs to stabilise the vessel. A diving team carried out temporary repairs to her hull and pumps were deployed in her fish hold and engine room to keep any further ingress of water at bay until the vessel’s own pumps could cope.
With the vessel’s situation now stable, the full planning of a rescue attempt could take place. To ensure the safest way of releasing the fishing vessel from the reef, operatives from Ocean Kinetics carried out a sonar survey, in the shallow waters close to the reef to ensure that the correct track could be chosen. The combined horsepower of LPA harbour tugs Knab and Kebister could then be connected by towline to free the Rosebloom from her perilous perch at the flood tide and the vessel was successfully floated free.
Once free of the reef and safely berthed in Lerwick, a more extensive temporary repair could be made, to allow her to be travel safely to shipyard for full repairs. The part of her hull that was most damaged was exposed from the inside and steel cofferdam welded around the affected area to create a sturdy second skin. This reinforced box was MPI tested and confirmed to be airtight once the welding was complete.
A second major piece of work was carried out by Ocean Kinetics divers to effect a temporary repair on the vessel’s rudder. The divers recreated the gudgeon box into which the rudder sits, as it had been sheared off during the grounding.
Once the hull integrity was stabilised by the internal work, and the rudder now operable again, it would be possible to sail the Rosebloom to a shipyard for full repairs. The build of the 28 metre long pair-seiner was completed in Denmark as recently as 2016 and it was decided that the best location for her to be fully repaired was back in Denmark. The passage to the shipyard was successful and took place without hitch. It is estimated that the full repairs will take 2 or 3 months, before she returns to the fishing.
Speaking once the vessel was safely docked in Denmark, co-owner Sandy McLeman said, “We were extremely grateful for the help we received from John [Henderson] and his team at Ocean Kinetics, they had a very positive ‘get it done’ attitude and were key players in getting the vessel back into Lerwick.”
“The dive team and the guys who did our temporary repairs worked very hard to get us ship shape to steam away. Help that we will be forever grateful for.”
