N-Sea: No Surface Decompression Needed with TUP Diving System

N-Sea No Surface Decompression Needed with TUP Diving System

N-Sea re-introduces the unique and revolutionary TUP Diving System® for its offshore activities.

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

The TUP Diving System® is comprised of a 3 men bell, launch and recovery system, triple lock decompression chamber, an air/mixed gas dive control and hyperbaric rescue craft.

The TUP Diving System effectively doubles the workable bottom time when compared with traditional air diving options. This makes 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 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.

The main benefits of this TUP Diving System® are:

• No surface decompression interval

• Significant increase in workable bottom times

• 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.
