Once the port anchor began its ascent, the hawser line gave way and started to rise, but it was found to be a much heavier load—requiring the use of the workboat’s hydraulic crane.

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 installation of complete SOx scrubber systems is entirely possible without taking the vessel out of the water. 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.

The year 2020, and with it the Sulphur regulation for the use of heavy Sulphur fuel oil, is approaching fast. Starting January 2020, it will be illegal to run a ship using fuel containing more than 0.5% Sulphur without the operation of a scrubber, an exhaust cleaning gas system.

Subsea 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.

Subsea Global Solutions started its underwater repair process by establishing load-rated rigging points above the propeller using 4F Class A wet welding procedures to allow safe new replacement propeller blade transfer of the propeller blades.

Over the past few months, Subsea Global Solutions has been called on to complete propeller straightening’s and repairs all over the world, including – Canada, Panama, Uruguay, Singapore, and El Salvador. In each case, a team of highly trained Subsea Global Solutions Diver / Propeller Technicians attended the vessel, along with our proprietary large or small propeller press (depending on the job scope) and propeller sectional reduction / optimization gear.

By utilizing a multi-stage polishing process and diver / technicians trained in the proper analysis of the propeller condition, Subsea Global Solutions' process has proven to be an integral part of fuel efficiency programs. The benefits of maintaining a polished propeller have been known for years, but what has not been known is "how smooth is smooth"?

Over the past few months of 2019, Subsea Global Solutions has performed a number of high-capacity underwater repairs across the globe. A great number of these repairs have focused on seal replacement.

As part of the cruise industry’s focus on the environment, a vessel operating in the South Pacific developed a minor problem with both of its shaft seals.

Back in November, a fully loaded bulk carrier contacted Subsea Global Solutions with a shaft seal issue. Initial reports from the vessel were that they were losing all stern tube oil into the vessel, they were experiencing heavy water ingress through the FWD seal system into the engine room, and the internal seal system clamp ring shifted approximately 70mm inboard.

Class approved shell plate underwater damage repairs to offshore semi-submersible platform without drydocking.

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.

A Blue-Chip oil & gas company incurred several defects and cracks in a critical attachment member of an FPSO’s hull – these defects required repair to allow continued operation.

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.

Earlier this year, Subsea Global Solution’s office in Busan, Korea completed a biofouling cleaning campaign on one of the largest vessels in the world. A floating liquified natural gas (FLNG) vessel – with an LOA of 488m – it was launched in 2013 and took almost four years to complete, whereby the vessel’s hull had expectedly collected a significant amount of fouling.

A deep-sea bulk carrier fully loaded with goods had become immobilized due to a failure of the aft shaft bearing. In the past, not much could be done to help a vessel in this situation. With no way to transit on its own power and loaded with a perishable cargo, an economical solution needed to be developed quickly.

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 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.

We began the operation inside the vessel by templating the immediate area of the hull around the existing fracture. The hull templating serves two purposes, it tells the size and geometry of the insert plate and it provides us with the surface area and geometry needed to fabricate the cofferdam onsite.

This 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.

The repair was based on underwater welding only, eliminating the need for the installation of open top cofferdams or other barriers that would allow dry welding repairs to take place, which requires more time and resources. Subsea Global Solutions Long Beach mobilized two 5-man teams of commercial divers and welder divers to operate around the clock during cargo operations until the underwater repair was concluded.
