The TUP (Transfer Under Pressure) Diving System, designed and built in house by N-Sea, has an track record with over 10,000 incident free dives to date. N-Sea said the system has undergone a comprehensive refit and has been converted to allow it be used as a mobile system. It is deployable from most DPII support vessels and platforms and will be online from August 2013.

The TUP Diving System is comprised of a three men bell, launch and recovery system, triple lock decompression chamber, an air/mixed gas dive control and hyperbaric rescue craft.

The TUP Diving System doubles the workable bottom time when compared with traditional air diving options, N-Sea said, making the system cost efficient. When compared with saturation systems, the TUP Diving System can be a cost competitive alternative for operations between 35 and 50 m water depth, the company added.

The most important factor to consider is safety. With divers being transferred under pressure the surface decompression interval is removed.

The TUP Diving System refit is being carried out to the highest standards and conforms to IMCA guidelines and meets Lloyds classification requirements.

Accdording to N-Sea, the main benefits of TUP Diving System are no surface decompression interval, significant increase in workable bottom times and mobility.

With this addition to N-Sea’s diving operation, the TUP Diving System enables N-Sea to offer a safe, complete and very cost effective solution to customers.

N-Sea provides the following services to the oil and gas, renewable and subsea cable industries: Subsea Construction Support, Diving and ROV, IMR, Survey and Positioning.
