Drill Rigs and Offshore vessels- Big Thrusters require the Right Solutions!

IMG_1630Subsea Global Solutions has remained very busy in early 2014 supporting several oil and gas clients with inspections, maintenance and thruster exchanges.  Working both in-shore and off-shore, unique underwater solutions were developed for various semi-submersible and crane vessels to safely, efficiently and effectively complete the scope of work.

The exchange of large demountable azimuthing thrusters is a systematic process that involves close coordination between inboard operations, outboard operations and lifting services.  This systematic approach is quite straight forward when performed in-shore in sheltered areas, but when performed almost 100 nautical miles OFFSHORE in the dead of winter, this systematic process takes on a new life of it’s own.  Unique processes with built in redundancy, specialized fit for purpose equipment and a concrete communication plan need to be in place to keep the work moving forward efficiently and safely for all personnel in and out of the water.  Developing a flexible dive plan with built in redundancy at all levels is essential when working in such conditions.  Current, sea state and strong winds made the location challenging especially when rigging 75 ton thrusters into position!  Subsea Maersk Developer- FixedGlobal Solutions provided all dive operation management, personnel and equipment to provide around the clock diving operations from multiple dive platforms both on and off the semi-submersible.  By remaining agile and able to adapt to the ever changing weather conditions, Subsea Global Solutions’ was able to provide continuous support for the thruster exchange process.  This allowed all work to be completed to the full satisfaction of the owner; even after others failed.

Bringing experience and a can-do attitude within the entire organization from top to bottom is what makes Subsea Global Solutions unique when performing these large projects in the Oil and Gas industry.

Demountable Azimuthing thrusterSimultaneously in other parts of the world, Subsea Global Solutions  was servicing two other oil and gas installations.  One Drill Ship required a detailed Underwater Inspection in-Lieu of dry docking (UWILD) for class while the other vessel, a large crane ship, required the exchange of demountable propulsion azimuthing thrusters weighing approximately 60 tons.  Both projects took place in the Caribbean.  Operating efficiently within the time parameters and dive windows in accordance with both vessel operator’s stringent diving regulations has made Subsea Global Solutions the company’s “turn to” resource for all of their diving needs.

The Oil and Gas market is enjoying Subsea Global Solutions’ professionalism from start to finish.  Delivering on its core values of quality and safety, Subsea Global Solutions has demonstrated that Quality Service is “not an Act but a Habit”.  Additionally Subsea Global Solutions has demonstrated that Safety’s the “Golden thread woven into our culture”.   Let us demonstrate all of our core values for you!  We remain available at anytime to develop projects with you.

Stabilizers- When Oil and water Mix- No one is happy!

DSC04105Stabilizers play in an important role on cruise vessels.  They help keep the “cargo” from complaining and help keep the martinis on the table tops as the vessel cruises the high seas.  However, when seals leak on the stabilizers, no one is happy.  While operating in the Mediterranean, a stabilizer on a cruise vessel experienced excessive sea water ingress.  This forced the unit to be taken out of service and housed.  The Lube Oil system was contaminated with sea water causing concerns of mechanical damage to the Stabilizer drive system and concerns of oil release to the environment.  With a full itinerary and no scheduled dry docking on the horizon the client contacted Subsea Global Solutions to evaluate options.

DSC04090Subsea Global Solutions is the leader in the development of flexible Hyperbaric Cofferdams for various applications which require a temporary dry environment formed in a normally wet area of a vessel.  Considering the seal type installed on this stabilizer and to perform a permanent Class and OEM approved repair, a Hyperbaric dry environment needed to be developed so that new seal rings could be installed.  This required Subsea Global Solutions to engineer a flexible Hyperbaric cofferdam that would encapsulate the stabilizer seal pocket.  With in-house engineering staff and specialized 3-D design and modeling software, Subsea Global Solutions engineered the necessary Flexible Hyperbaric cofferdam for this type of application.  Since this repair has never been executed underwater before a proper engineered solution was required.  Subsea Global Solutions together with the stabilizer and seal manufacturer evaluated the technical details of this repair and determined that a safe and DSC04089efficient process of repair could be performed .  Subsea Global Solutions is the preferred and approved underwater service company globally approved by the OEM to bond these seal rings underwater.  With this in mind, a repair procedure was developed together with a detailed time line in order to perform the work without taking the vessel out of service or affecting the vessels itinerary.

In the port prior to the underwater intervention, Subsea Global Solutions loaded all of the gear onboard and set up the gear for the intervention.  With the gear and dive station prepared in advance, immediately upon arrival to the repair port of call, diver technicians entered the water.  Utilizing Subsea Global Solutions‘ “A” class wet welding procedures, all attachment points for the flexible Hyperbaric cofferdam were properly positioned and installed.  Once the flexible Hyperbaric Cofferdam was installed, the diver technicians dewatered the space and went to work in a dry and controlled environment.  The existing seal assembly was disassembled and the problem was immediately identified.  Defective rubber seal rings were removed and brought to the surface for evaluation.  With the problem isolated and new seal rings in hand, Subsea Global Solutions bonded the new seal rings in accordance with the OEM’s approved vulcanizing process.  Utilizing the same bonding equipment, adhesives and process used in the dry dock by the OEM, Subsea Global Solutions performed the work with it’s factory trained and certified OEM diver technicians, Subsea Global Solutions completed the work without delay or schedule changes for the client.  This repair was performed in accordance with the OEM’s approved process and received Class’ approval as the repair being considered permanent.

DSC04099Start to finish, the team performed the entire seal renewal in less than the thirty (30) hour port stay of the vessel.  This allowed the vessel to remain in service and not be delayed on it’s cruise.  With the stabilizer back in service, the cargo could enjoy a nice smooth ride and the martinis stayed put!  Making the impossible possible is what Subsea Global Solutions is all about.  We remain on the forefront of developing new repair alternatives.  Bring your problem to us and let’s see what we can develop for you!

In the German market the shipping community is mainly represented by medium sized family owned companies, besides the two famous liner companies Hapag Lloyd and Hamburg Süd. The German owners impressively operate the largest container fleet in the world, reflecting approximately 70% of all containerships. In the time frame 2000-2008 this fleet showed an expansion in large-size container vessels. This development gave the owners more and more problems in finding suitable repair locations to service these new large vessels. This pushed Germania Shipyard Agency to look for new ways in ship repair. Hence, in 2008 they took the chance to represent Subsea Solution Alliance, which is nowadays Subsea Global Solutions. This new cooperation was quite important for them as they saw a big potential in under water services.

When others can’t- We can!- Underwater Shaft seal replacement

DSC02693More and more debris is being found in our oceans throughout the world.  This debris includes large masses of fishing line and net.  While transiting the southwestern USA, a cargo vessel began experience excessive sea water ingress on the aft shaft seal.  Thinking it was a simple matter of just cutting away some fishing line, the ship manager contracted the work with a local dive company to inspect the stern tube and remove the fishing line.  In the process of fish line removal it was confirmed that some of the mono-filament fishing line was sucked into the lip seal arrangement.  Through the extraction process further damage to the seal arrangement occurred.  With the job exceeding the capabilities of the dive contractor on site, Subsea Global Solutions was called in to perform a permanent repair to the at shaft seal.  Within 16 hours of being initially notified by the ship manager that our services were required, Subsea Global Solutions mobilized all of the necessary equipment and personnel to perform this aft shaft seal repair in less than 48 hours.

DSC01708With the rope guard already removed, Subsea Global Solutions installed the Transhab flexible hyperbaric cofferdam over the affected area of the vessel.  With the critical area of the stern tube dry and in a climate controlled environment, Diver / Technicians entered the Transhab and fully assessed the aft shaft seal system.  With Original Equipment Manufacturer factory training and certification from the manufacturer of the seal system, the Diver / Technicians began a class approved and OEM warranted repair.  All lip rings were properly disassembled.  The seal housings were evaluated, overhauled and prepared for re-installation.  The shaft seal liner was inspected, grooving measured and evaluated.  It was determined that the existing liner was within factory specifications so replacement or removal of the spacer plate and or liner was not required.  If required, the seal shaft seal spacer plate or shaft liner could have been removed and or replaced in a completely dry environment in the TransHab flexible hyperbaric cofferdam utilized by Subsea Global Solutions.

With all critical components measured and cleaned, the Diver / Technicians performed the new lip ring bonding process.  Utilizing the same process, same jigs, and glues utilized by factory approved technicians performing the work in the dry dock, the Diver / Technicians completed the most critical part of the shaft seal replacement.  Once the seal assembly was completely assembled, the Diver / Technicians performed factory required feeler gauge tests and pressure tests.  All pressure tests and mechanical inspections were performed to the full satisfaction of the attending ship manager and class surveyor.

In less than 43 hours, Subsea Global Solutions came and went.  We are your trusted resource to deliver unrivaled service.  The Ship Manager was excited to see the stern lights go over the horizon without any notations or open class items.  Subsea Global Solutions is your trusted resource to keep your vessels in service.  One world, One Ocean; Subsea Global Solutions is your underwater contractor any where around the world.

My Stabilizer sprung a leak!- Underwater Crux Seal exchange

DSC00126While cruising the beautiful waters of the Mediterranean Sea, water ingress was reported on one of the vessel’s stabilizer fins.  After consultation with the equipment manufacturer it was determined that an in-water inspection and potential repair was required.  With no experience performing this type of repair underwater, the client and Original Equipment manufacturer turned to Subsea Global Solutions for support.  Mobilizing from our location in The Netherlands, Diver / Technicians arrived in Italy to closely inspect and repair the stabilizer crux seal package due to this leakage.

Initially the upper retaining ring to the stabilizer crux seal package was removed.  The first seal package was replaced underwater with spare parts found on board.  With the seal package properly installed and properly positioned, the retaining ring was reinstalled and torqued to manufacturer’s specifications.  The Inspection continued to the lower crux seal assembly.  Upon inspection, damage to the seal package was reported by the Diver / Technicians.  A portion of the first seal package was seen protruding past the retaining ring between the crux and retaining ring.  The lower retaining ring was removed, and the first seal package was removed.    After removing the first seal package an abnormality was seen by the diver / technicians so more seal rings were removed.  All seals were removed and it was determined that the #4 last hard seal split ends were overlapping rather than being flush.  This defective seal was removed, and cut to the proper length.  With the seal properly installed, the diver / technicians replaced the remaining seals.  With all seal packs properly installed the lower retaining ring was reinstalled and torqued to the Manufacturers specifications.  The vessel continued on it’s voyage without any interruption to the schedule with it’s crux seal leakage repaired!

Subsea Global Solutions again delivers unrivaled service.  Considering the fact that the Original Equipment Manufacturer never before performed a repair of this magnitude underwater, we have developed yet another new process of repair.  With our in-house engineering and experienced operations teams available 24 / 7, developing unique installation specific repair procedures is business as usual.  This client and Original Equipment Manufacturer continue to enjoy the quality and dedication to serve of each and every member within the Subsea Global Solutions’ team.  Let us demonstrate to you what we can do!

Tunnel thruster out – Tunnel thruster in- All in a day’s work!

Carnival Magic-Aug 201325Subsea Global Solutions remains focused on delivering unrivaled service to its clients around the world.  When cruise vessels require underwater equipment maintenance and repair, our team of highly skilled diver / technicians dive into action to support their needs.  While keeping the vessel in service Subsea Global Solutions followed a detailed time line in order to exchange a damaged tunnel thruster lower gear box before the vessel reached a location requiring it’s use.

Carnival Magic-Aug 201334Working from the vessel’s shell lock door, Subsea Global Solutions set up the mobile dive station  and equipment while at sea one day prior to the start of operations.  Once in the first port of call, the diver technicians dove into action.  Preparatory operations began with the installation of load rated pad eyes at strategic locations along the ships hull and inside the thruster tunnel.  All Welding was done by coded “A” class wet welders under Subsea Global Solutions’ class approved wet welding procedure.  In parallel, other diver / welders began the weld installation process of rigging equipment for Subsea Global Solutions Flex door system.  The Flex door system allows our team to “dewater” the thruster tunnel and create a dry environment for underwater service.  In parallel to underwater operations, diver / technicians worked together with other contractors and the ship’s crew to rig the electrical motor off of the thruster motor foundation, prepare the tunnel thruster for underwater demounting and preliminarily installed the internal cofferdam “The Dome”.  With preparatory work completed, the extraction process began.

Carnival Magic-Aug 201332Subsea Global Solutions began the extraction process by gouging away the tunnel thruster stay plate utilizing a carbon arc gouging system.  In parallel, underwater and internal rigging was installed on the tunnel thruster lower gear box.  In the thruster room, the diver / technicians removed the thruster mounting bolts.  The stay plate was then completely cut and removed.    The thruster lower gear box was rigged away from the thruster tunnel.  A new exchange tunnel thruster was prepared by the OEM representative on site for installation by Subsea Global Solutions.  Shortly after the old thruster was extracted a new tunnel thruster was installed.  Welding immediately commenced on the tunnel thruster strut plate in the thruster tunnel using the “A” class wet welding process.  In parallel, the diver / technicians properly torqued the tunnel thruster bolts into place.  Next, the diver / technicians installed the flex door system for the installation of the tunnel thruster blades.  With all of the blades properly installed, the tunnel thruster pressure test and completely installed, the thruster stay plate was fully welded, the rigging pad eyes and flex door rigging system was extracted and the tunnel thruster was prepared for final testing and operation.

From start to finish, Subsea Global Solutions was the trusted resource for the vessel.  Ensuring the cruise vessel remained in service and on schedule keep the passengers focused on their vacation as opposed to the ship!  We appreciate the trust instilled with us by our dedicated and loyal customer base.  We remain standing by to support you, our clients, anywhere any time!
