SGS Reseats Shifted Tailshaft Afloat and Executes a Stern Seal Repair

Double Bow Thruster Removal by SGS

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 SGS, which would help to eliminate the need for additional tug cost.

The project was executed with two SGS 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.
