    N-Sea completes diving project using TUP system

    Projects and Operations // October 1, 2014

    Inspection, maintenance and repair (IMR) specialist N-Sea has completed its inaugural diving scope with its innovative Transfer Under Pressure (TUP) Diving System.

    The work involved Xmas tree assistance with the deployment of the TUP Diving System for client Oranje-Nassau Energie (ONE) on its project 'L6 Diving Services' at the location L6D in the North Sea.

    For the project, N-Sea stationed the closed bell system on the jack-up rig Paragon C46-1 between July and September. The project team included a 24/7 operations crew at the site of this challenging scope, during which the system proved its full potential.

    The TUP Diving System was designed and built in-house by N-Sea, and comprises a three man bell, launch and recovery system, triple lock decompression chamber, gas diver control (Air/Trimix/Nitrox) and hyperbaric rescue craft.

    During the last year the system has undergone a complete refit and has been converted to allow it to be used as a mobile system, deployable from most DP2 support vessels and platforms.

    Gerard Keser, CEO of N-Sea, said: “The TUP Diving System enables N-Sea to offer a safe, complete and very cost effective solution to customers. The system is safe, because there is no surface decompression interval and the system allows protected transfer through the splash zone. It’s an enhanced proven solution that increases the workable bottom time.”

    Theo Bergers, COO of ONE, said the key factors for choosing the TUP Diving System were safety and workability.
