Learn how Subsea Global Solutions performs underwater propeller blade straightening to repair large propeller bends.
During cargo operations, a submerged pile pierced through the hull. Subsea Global Solutions worked together with owner and class to develop repair plan that included the design and installation of an engineered cofferdam.

View full case studyThe 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.
View full case studyThis complex underwater repair was completed to the client's satisfaction in 5 days in conjunction with various other repair works. Subsea Global Solutions managed both the underwater and internal portions of this repair to ensure each phase was executed seamlessly.
View full case studySubsea Global Solutions can restore your propeller blades as a permanent repair, to OEM design geometry by cold static loading with our underwater propeller blade press.
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.

Subsea Global Solutions' involvement is focused on precision cutting of the hull penetrations for the sea chest openings and overboard spool pipe installation below the waterline.

View full case studyOur Certified Propeller Technicians perform sophisticated Class-approved underwater propeller repairs, which include straightening large bends, precision cropping and design modifications worldwide.
Upon completion of extensive on-site practical and formal training, our Technicians are qualified to accurately assess propeller condition and determine the best-engineered repair solution to maximize propulsive efficiency.
Class approved permanent repairs- previously possible only in a workshop after propeller removal - are now possible underwater using proprietary equipment and procedures.
Large deflections can be straightened underwater in hours; dockside or at anchor. The underwater straightening process entails many cycles of cold static loading applied in sequence throughout the deflection. Sections up to 50mm thickness can be restored to design geometry and approved by Class as permanent repairs using our proprietary cold static loading and precision laser geometry measurement equipment and procedures.
Subsea Global Solutions maintains a full range of purpose designed straightening equipment sizes to handle everything from tunnel thrusters to Super Yachts to ULCCs.
Straightening systems are designed and packaged for swift worldwide mobilization from key Subsea Global Solutions offices by air cargo or even as checked baggage on passenger flights.
