Subsea Global Solutions is the leader in underwater services for the cruise industry globally.  The key to our success is proper planning and communication with all stakeholders involved with the project.  Prior to the delivery of the performance enhancing propeller boss cap fins, Subsea Global Solutions worked together with the equipment manufacturer to develop an OEM approved underwater installation procedure.  This required design enhancements to be incorporated into the new propeller boss cap, required specialized tooling to be developed by Subsea Global Solutions and an innovative procedure to be developed so that the OEM requirements were incorporated and the client’s operational requirements were incorporated.  Once the procedure was approved by all the stakeholders, Subsea Global Solutions worked toOLYMPUS DIGITAL CAMERAgether with the client to incorporate the required work scope into the itinerary of the vessel.  This meant that during port stays specific portions of the work scope would be completed at strategic times during the voyage.  This allowed the vessel to remain in service, and to continue in operation safely and efficiently.  The cruise passengers continued their vacation experience without any impacts.

Once the manufacturer delivered the equipment to the vessel and Subsea Global Solutions’ equipment was staged onboard, the execution of the work begun.  Port by port time lines were reviewed with onboard personnel and Subsea Global Solutions’ Project Management staff onboard maintained continual communication with shipboard and operations management staff during the execution of the work.  This allowed the shipboard staff and vessel management staff to be prepared for departure on time and schedule.
