Subsea Global Solutions has revolutionized the underwater methods of repair of rudders and stabilizers. By using underwater cofferdams (either atmospheric or hyperbaric), fully approved mechanical or weld repairs can be performed to rudders and stabilizers. If underwater removal or extraction is required for a rudder or stabilizer, Subsea Global Solutions floats damaged stabilizers or rudders away from the vessel using the aqueous environment as a crane. Buoyancy control solutions have been developed for underwater lifts up to 300 tons. Underwater seal replacement, including bonding of new seal rings, is possible for stabilizers without taking the vessel out of service.
Permanent underwater wet weld repairs to eroded rudder surfaces and weld seams, dewatering of rudder blades and mechanical repairs to Hi-Lift rudders is all available globally through the expert technicians of Subsea Global Solutions.

View Full Case StudyThe 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.
View Full Case StudyThe 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.
