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.

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.

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.

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.

All Hands on deck- SGS Unites!-March 2017

As announced in early March, Subsea Global Solutions completed the acquisition of All-Sea Underwater Solutions.  This acquisition allows us to provide enhanced service support to our clientele by:

  • Expanding our portfolio of services
  • Growing our unified global footprint of wholly owned subsidiaries
  • Adding stability to our business for organic and acquisition growth
  • Strengthens our pool of qualified Diver / Technicians
  • Expands our technical resources so that we can continue to innovate and create innovative underwater solutions

Subsea Global Solutions was put to the test DAYS into the announcement of this acquisition.  A vessel operating on a time critical cruise itinerary developed a leak in its shaft seal.  This emergency required Subsea Global Solutions to engage it’s global network to deploy personnel and equipment to a port location in the Far East.  With the correct equipment assets strategically located in SGS’s Korea and Vancouver facilities, equipment was immediately dispatched to the required repair location.  Since the repair was time critical, trained and certified Diver / Technicians were deployed from SGS’s Korea, Los Angeles, Miami, Seattle and Vancouver locations.  Careful planning and timely execution was necessary for this time sensitive repair.  The rope guard was surgically removed using a carbon arc gouging system.  By utilizing this specialized technique the weld can be effectively removed without damaging the base metal; thus saving critical time in material preparation once the repair is completed.  With full access to the seal, the extent of the damage could be evaluated.  As seal lip ring renewals was required, the Diver / Technicians installed the Transhab, a flexible Hyperbaric cofferdam.  With precision and care the damaged seal lip rings were removed and replaced using a factory approved bonding process and bonding agent.  Once completed, Quality assurance pressure and measurement tests were performed to assure an OEM guaranteed repair was completed.  The rope guard was then welded back to the stern tube by coded welder / divers utilizing the class approved Class “A” wet welding procedures of Subsea Global Solutions.  With integrated equipment and all repair team members working to the same technical repair process, the repair was successfully completed utilizing the combined resources of Subsea Global Solutions LLC and its newly acquired subsidiary.

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.
