One ship, two complex repairs and one really happy client

In April 2013 a container vessel experienced water ingress into the stern tub and oil lost from its Controllable Pitch Propeller (CPP) blades seals. The client arranged an in water inspection and discussed the results with the experts of Subsea Global Solutions. Based on the findings, it was determined that the  CPP Propeller blade Palm seals and the Stern tube aft seal required replacement. Working together with the client the operations team of Subsea Global Solutions scheduled a class and OEM approved repair as soon as the vessel received all spare parts on board.

Working around the clock the stern tube aft seal was exchanged in a little over 48 hours.  Utilizing Subsea Global Solutions’  Transhab, an inflatable hyperbaric cofferdam, Subsea Sea Global Solutions’ factory trained and OEM certified diver / seal technicians completed the renewal of the aft seal in a completely climate controlled dry environment.  With this phase of the repair completed, the DSCN5865crew size was reduced to finish the replacement of the CPP Propeller blade Palm seals. The ship ballasted the stern out of the water so the prop was half out and the team changed the seals at the 12 o’clock position. Working together with the Original Equipment Manufacturer, the pitch oil system was isolated and prepared for the performance of an in water repair. With the system properly arranged the first propeller blade was released from the propeller hub. Once the blade was away, the team changed the seal, the seal ring and re-installed the propeller in accordance with the approved OEM and class approved procedure. The propeller blade bolts were then torqued to the proper settings and the same procedure was followed for the other blades.

Not long after the job was completed, the operations team at Subsea Global Solutions received an e-mail from the Technical Director of our client who witnessed the operations on site.   He stated “I enjoyed watching your team’s professional attitude, knowledge and kind of persuasive cool approach, i.e. “don’t worry & relax, we have seen it all and we are in control”, though still minding and respecting our specific needs at site.” To say the least, it is gratifying to read that we have DSCN5830delivered our services in line with our mission and vision by being your most valued and trusted resource through unrivaled service.
