No solution? Think again! – Aft shaft bearing repair, Hong Kong – April 2018

Subsea Global Solutions was recently contacted to provide a solution for a vessel stuck in a very difficult position. 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.

After a failed attempt to repair the vessel by a competing company, SGS was given the opportunity to provide their expertise and decades of experience. An underwater repair solution was developed where none had existed before. Due to the deep draft of the vessel, special attention was paid to how the repair would be carried out. A large highly skilled team was required to provide the vessel with non-stop 24hour operations. With only a few days to mobilize, SGS technicians and equipment landed in Hong Kong and prepared for the repair.

In only four days the SGS team accessed the aft shaft bearing and repaired the system to allow the vessel to continue their voyage as normal. This repair allowed the vessel to travel safely to their destination and offload their cargo. Once free of cargo the vessel continued to a dry-dock facility where the aft shaft bearing was replaced.

This repair was overseen and is approved by classification societies. Aft shaft bearing failures in the past have dictated immediate dry-docking. BUT – now with a revolutionary repair strategy, SGS can offer a temporary repair to allow vessels in similar situations to voyage. SUBSEA GLOBAL SOLUTIONS has proven once again that it can provide vessels with a fast and vastly cost-effective repair solution compared to any alternative.

Propeller Repairs – Worldwide – March 2018

Over the past few months, Subsea Global Solutions (SGS) 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 SGS 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.

Once onsite, the Diver / Propeller technician enters the water to map out the damage to develop a repair plan together with SGS’ Propeller and Hydrodynamic specialists. After the solution is developed, the best repair option is chosen to optimize propeller hydrodynamic performance considering the extent of damage and regulations governing the repair.  Incorporating all of Subsea Global Solutions’ techniques, including cold static load straightening and optimized section reduction techniques usually delivers the optimal solution to the affected vessel.

Propeller – As Found

Propeller – As Released

Cold Static load propeller blade straightening incorporates the use of SGS’s proprietary propeller press. A thorough inspection is done prior to straightening to ensure the damaged area is free of micro fractures, and any small surface fractures are removed before the straightening process. The Diver / Propeller technician focuses the power of the cold static load press to calculated sections of the bent blade to restore the geometry to near original geometry. This process is approved as a permanent repair by most class societies.

Sometimes excessive damage, cracking or bends beyond the capability of the press – make it necessary to optimize the sectional area of the blades instead. In this process sectional area optimization to the damaged blades is performed.  A calculation is done to determine the static and hydrodynamic affect this sectional area reduction will cause and the propeller is properly balanced to ensure vibration free and minimal performance lost operation.

Incorporation of several propeller repair techniques allows Subsea Global Solutions to execute permanent repairs with minimal to no performance loss.  Repairs are performed rapidly in 12 to 24 hours. This allows the ship to sail in a timely manner, and significantly reduces the time and cost of drydocking. Delivering value adding services is what makes our  happy.  Keeping cash in their pockets makes them smile and assuring them no disruption of service gives them peace of mind in this competitive market place.   Let Subsea Global Solutions be your trusted resourced to deliver unrivaled service!

Twin Shaft Seal Repair – South Pacific – January 2018

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.  To ensure continued operation with no delay to operations, the cruise operator chose to perform an in-water service of these shaft seals during scheduled port stays on their itinerary.  Subsea Global Solutions (SGS) was trusted to execute these time sensitive and critical stern seal replacements concurrently on this twin Azipod Cruise ship.  This work required two specialized TransHab flexible Hyperbaric cofferdam systems and support equipment as well as over 25 trained and certified Diver / technicians to perform this work around the clock on both propulsion units at the same time.  The work was completed through cooperation of all the worldwide SGS offices along with cooperation from local vetted partners for local support.  Preparatory work was performed in multiple ports along the vessels trade route through the South Pacific.  This prepared the vessel for the actual seal replacements which were carried out in a location where the vessel remained in port for 48 hours.  By closely planning this repair around the ships itinerary the work was completed on time; avoiding any unscheduled delays for the vessel or inconvenience to any passengers.

The work was executed very smoothly and completed with no delays.  SGS received excellent support from the vessel’s Master, Superintendent and all of the crew.  This allowed Subsea Global Solutions to deliver on time and on budget.  Delivering unrivaled service is what SUBSEA GLOBAL SOLUTIONS is all about.  Give us your challenges and we’ll give you solutions!

Stern Seal Repair – Romania – November 2017

Back in November a fully loaded bulk carrier contacted Subsea Global Solutions (SGS)  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. By this report, it was immediately known this was not a typical shaft seal repair.

The vessel was towed from an anchorage in Russia across the Black Sea to a more favorable location in Eastern Europe. Teams from SGS offices in Vancouver, Miami, Long Beach, Halifax, Houston, and Tampa were sent to attend.

Once inspections began, it was found that the tail shaft had dropped outside acceptable tolerances due to bearing failure. This bearing failure  was the root cause of the initial reports.

A plan was put together for an emergency repair for the vessel so it could continue on its wa y to  deliver cargo and then go to dry dock. Working alongside the responsible Class society, it was decided that if the shaft seal integrity could be reinstated and a running test could be conducted with Class in attendance to their satisfaction, the vessel would be allowed to sail.

For the seals to be brought back into eccentricity with the shaft, modifications to the seal housing flange were conducted. This consisted of disassembly of the entire split type seal system inside the SGS Transhab habitat and the housing flange mofified in accordance with specifications developed by SGS’s engineering department with consultation with the seal supplier.  Once machined, the system was assembled with new bonded shaft seals. The aft seal assembly was aligned with the shaft eccentricity within original tolerances.

The internal seal assembly and clamp ring was put back into radial and axial alignment and backed up by an additional hold back fabricated onsite as extra precaution.

After working around the clock in extreme weather, the running test was conducted pier side. All testing was completed and Class approved for the vessel to make a one way trip to its next port of call for cargo discharge. The vessel arrived without fail, discharged it’s cargo and entered the dry dock for permanent repair.  Throughout this transit the vessel maintained close  contact SGS by providing continuous updates to SGS technicians.

Subsea Global Solutions has pioneered the methodology to performing permanent repairs and replacements to shaft seals underwater in a wet or dry environment. By working closely with our OEM partners, Subsea Global Solutions sets the standard for shaft seal renewal while a vessel remains afloat and in service.  With the largest wholly owned footprint of any company in underwater ship repair, we are THE ONE SOURCE FOR GLOBAL UNDERWATER SOLUTIONS.

Biofouling Cleaning Campaign – Korea-Oct 2017

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. On several occasions prior to the start of this project, SGS Busan was onsite to assess the degree of fouling and to carry out several tests that would determine the best option for removing the fouling. Strict environmental laws had to be taken into consideration, and the antifouling coating used on the hull precluded divers from using a brush cart system. At the end of the cleaning trials, it was determined that the most effective way to clean the hull would be a combination of hand cleaning (!!!) and the use of specialized cavitation based cleaning equipment.

The SGS project team consisted of 32 members, spanning our various offices. From there, two dive teams were created, including a project manager, supervisor, assistant supervisor, two diver medic technicians, ten divers, and an English-Korean translator. Both teams worked simultaneously on the port and starboard sides of the vessel, working 12 hour shifts from Monday to Friday. Simultaneous operations were a big challenge for the dive teams, and it was essential they were checked daily as the sail away date was closely approaching. Safety measures (following international oil and gas guidelines) were undertaken each day before any diving operations could begin.

Each location of the hull followed the same 3-step procedure, beginning with a pre-inspection that was witnessed by the client and guided by marine biologists, using video and still shots. Sea bay inspections were done via borescope, thus saving time by not opening the grids. Next, cleaning of the area would commence with the use of rubber scrapers and rubber hammers. Finally, a post-inspection was completed to determine the area was free of fouling and any invasive marine species, aided and witnessed by the client and marine biologists. This process continued until all designated areas of the hull were completed.

Over a 5 week period this project involved a total of 12,544 hours of labour, 156 hours of video footage, with 1526 photos captured! This was a large scale, operations heavy, and newsworthy project and all involved were happy with the success achieved at the end of the project!

Oil Leak Repair – August 2017

SGS Halifax received an emergency call recently that a ferry in a remote part of Northeastern Canada was experiencing an oil leak in the port stern tube. Our crew was quickly assembled and dispatched to the vessel to diagnose and repair the cause of the leak.

Due to the heavy traffic load at the height of tourist season, the ferry schedule could not be interrupted – and as such, all works were to be completed at night while the ferry wasn’t running. SGS dive technicians completed an initial inspection of the ferry, and removed previously installed sealing material to gain access to the port forward fairwater ahead of the strut. After further removal of the fairwater, the source of the oil leak was found – a degraded weld in five locations, between the stern tube and port bearing.

SGS Class A certified wet welders were on site to complete the permanent repair to the attending surveyor’s satisfaction. Further inspection confirmed that the leak was repaired. An intermediate in-water survey was completed, revealing weld fractures in the rudder. These fractures were completely removed using carbon arc gouging techniques and the affected area was welded wet with SGS’ Class A class approved procedures and coded welder / Divers; returning the area to as built strength.

Leak test with full head pressure performed successfully

Propeller Anti-Sing Edge – August 2017

As the summer begins to wind down, crews across all Subsea Global Solutions (SGS) offices are busy with various ship and construction projects. This month, SGS got the call to head north to Alaska, where a cruise vessel required an inspection on the propeller’s anti-singing edge (ASE) profile. The vessel could not utilize some cabins onboard the vessel due to excessive propeller noise at certain operating conditions.  SGS diver / propeller technicians entered the water and carefully inspected the condition of the blades. After close consultation with the client and a review of the operating issues the vessel was experiencing, it was determined that a new ASE profile installation was necessary.

ASE as found

ASE application by SGS dive / propeller technicians

The new ASE profile measurements were then scribed on all blades for both port and starboard propellers. The propeller blade trailing edges were effectively re-profiled using specialized hydraulic equipment specifically designed for quick and accurate edge restoration. Once complete, the OEM trained diver / propeller technicians hand filled the profiles of the newly formed anti-sing edge to OEM specifications.


New ASE applied

The new edge successfully removed the singing, and allowed the vessel to begin re-booking the cabins that had been previously cancelled due to the noise. The vessel was able to depart on schedule, and the cruise line was happy to welcome more guests on board!  Subsea Global Solutions is your “One Source For Global Underwater Solutions”.

Blade Removal – July 2017

Last month, SGS Miami received an emergency call from a cruise vessel that was experiencing vibration in one of it’s propulsion units. An oil analysis of metal content proved that there was high probability of a component failure in the propulsion unit, which would increase the probability of a total loss to the propulsion unit. Working alongside the client, it was decided to secure the propulsion unit by removing the blades to prevent freewheeling during sailing.

The prep work was done during prior attendances to accommodate the vessel’s sailing schedule.  This ensured that the vessel could maintain its scheduled itinerary with no prolonged port stays. The prep workconsisted of the removal of the epoxy setting, welding of rigging pad eyes, the removal of blade lifting plugs, and the removal of bolt keepers.

When blade removal day arrived during the next scheduled call, SGS diver technicians removed all blades from the propulsion unit in record time!  As SGS has performed this service several times on prior vessels we were happy to report that this project was the most efficient and fastest this job has ever been performed! The client was thoroughly impressed by both how quickly we could provide them with a solution, and at how efficiently our operations progressed.  The vessel departed on schedule with SGS completing the work several hours early!

At SUBSEA GLOBAL SOLUTIONS we will always strive to exceed expectations – providing our clients with the most innovative, cost effective, high quality underwater solutions – anywhere in the world.

Propeller Straightening – June 2017

One morning in June, SGS Vancouver was contacted by a vessel in nearby Victoria, that was reporting excessive engine load and a significant shaft rate vibration. A dive team, including a Level III Propeller Service Engineer, were mobilized and onsite later that afternoon.

The initial inspection revealed that a large deflection in one trailing edge tip was the source of the engine loading and vibration. Our Propeller Service Engineer discussed repair options with the vessel’s Chief Engineer and Superintendent in the Far East. The client advised they would contact the propeller OEM to seek their advice, who in turn confirmed that SGS is their authorized underwater service provider, and that underwater straightening would indeed be their best option. The next morning, the repair was fully authorized and the vessel repositioned to Vancouver anchorage as it was the most cost effective location with suitable conditions for the repair.

Although our large press system was in Halifax, on the east coast of Canada completing another repair job for another client, we were able to expedite overnight service, delivering the press to our dive support barge by 0500 hrs one day after we completed the inspection. Within 6 hours of the works beginning (and less than 80 hours after the initial call), the job was completed to the satisfaction of the attending surveyor. The deflected section of the blade was restored to design geometry, along with a grinding and fairing repair of minor mechanical contact damage. Following a sea trial, the vessel’s Chief Engineer reported that all engine parameters and vibration levels had been restored to pre-damage values, and the vessel continued the voyage to Asia with a complete permanent propeller repair.

Thruster Changeout – July 2017

Over Canada Day, one of the many cruise vessels that pay a visit to Vancouver required service. During a normal port stay the SGS Vancouver team was tasked with removing one of the bow thrusters from the vessel. In order to carry out the extraction in a timely fashion, all preparation work was carried out a week earlier by a SGS team while the vessel was cruising in Alaska. In Vancouver, the thruster removable gear / propeller assembly was removed from the gear case and transferred to an awaiting crane. The thruster is currently being reconditioned by a local workshop together with the OEM technicians. When completed, the thruster will be reinstalled by SGS divers during a voyage layover. The experience was made especially memorable with Canada Day fireworks overhead while rigging the thruster from the water.

Subsea Global Solutions is your trusted resource to deliver unrivaled service anywhere and at any time globally.  We look forward to supporting your emergency and maintenance needs throughout the world.


Rudder Repair – March 2017

During a class inspection in Kingston, Jamaica, SGS noted severe material erosion to a container vessel’s rudder blade and rudder horn. The erosion was located on various areas of the rudder horn and blade and was so severe that it was allowing water ingress into the rudder.  The attending surveyor placed a condition of class on the vessel and required that it be permanently repaired within the next month.  With another two and a half years of operation in sight for the customer, drydock was not an appealing option so they requested SGS to evaluate an in-water permanent repair for this damage.

While SGS was developing a repair procedure to be submitted to class society’s damage department, material samples were taken from both the rudder horn and blade to determine its wet weld-ability.  Analysis showed the blade was conducive for wet welding, but the horn was not as it required pre/post heat treatments.  A strategic game plan was developed and approved by the customer and class to permanently repair these areas based on the material sample findings.  This repair procedure incorporated both wet and top side welding processes using SGS approved procedures.

Weeks of logistics were discussed and planned so that the vessel could attend the SGS home port location of Tampa, Florida for a scheduled repair.  the repair involved both SGS and the local shipyard.  The vessel unloaded cargo and shifted additional containers to trim the vessel so that the rudder horn was out of water for surface welding operations.  SGS could then repair the rudder blade in water and dewater the rudder while the shipyard repaired the rudder horn and the dewatered rudder locations in the dry.  Coded Welder / Divers were flown in from multiple offices to work around the clock for the scheduled time frame.  Working together as a team, both SGS and the local shipyard solved issues as a team while ensuring the best quality for the customer.

The result was that a rudder horn insert plate was permanently installed along with eroded areas were restored through “build – up” welding of multiple areas on the rudder blade and horn.  All areas passed NDE requirements and both the blade and the horn were dewatered prior to the vessel departed.  Class removed the condition of class and approved the repair as permanent.  The vessel once again resumed its normal schedule.
