Design flaws together with poor workmanship caused the bilge keel to fracture during operation in several locations. Subsea Global Solutions worked together with the owner and Class to perform permanent underwater wet weld repair on the fractures, without interrupting the production.

The client indicated that the tailshaft had shifted aft approximately 200 mm when the ship’s crew was doing maintenance on the shaft coupling. It resulted in the aft water seal losing contact with the liner, causing large amounts of water ingress into the stern tube.

The benefits of removing a damaged bow thruster afloat are many. The customer was able to prevent further damage to the bearings and gears caused by the presence of seawater in the gear housing and the procedures allows the units to be overhauled prior to the vessels next dry-dock—or, they can be re-installed afloat by Subsea Global Solutions, which would help to eliminate the need for additional tug cost.

The project was executed with two Subsea Global Solutions teams working around the clock. While the vessel trimming process was in motion, the team onboard the vessel began to drain the oil from the thruster while the dive team began removing the bow thruster tunnel gratings to gain full access to the bow thruster.

The client was in need of a turn-key—class approved—permanent repair. This included a single contractor that would manage the internal technical repair team, commercial diver team, prefabrication of the new spool pieces with flanges, final application of the 5-year warranty POLYFLAKE protective coating to 3000 microns on the new spool pipes, and achieving final class approval for the full repair procedure.
