The diving scope involved Xmas tree assistance with the deployment of the TUP Diving System for client Oranje-Nassau Energie (ONE) at location L6D in the North Sea.
For this project, N-Sea stationed the closed bell systemon jackup rig Paragon C46-1between July and September. The project team included a 24/7 operations crew.
The TUP Diving Systemhas been designed and built in-house by N-Sea, and is comprised of a 3-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 pioneering system has undergone a complete refit and has been converted to allow it to be used as a mobile system, deployable from most DPII support vessels and platforms.
“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,” Gerard Keser, N-Sea CEO, said.
