Test & Verification – Facilities and Services
Our facility in Laksevåg, Bergen, facilities an unique selections of pressure vessels to undertake hyperbaric pressure testing.
For all the chambers, testing can be performed using either gas or liquid as pressure medium. The tests can be monitored over internet on client request.
Our chambers varies from 8 to 50 000 litres and we have the ability to test the equipment up to 1000 bar – equivalent to 10 000 meter depth at sea.
Our personnel has participated in development of national and international test procedures and have conducted technical testing for the last 40 years. We conduct a wide range of test and verification services.
Loss of buoyancy testing
- Evaluates the buoyancy loss in materials or structures under high pressure. Important for ensuring the stability of submersible equipment in deep water.
Collapse testing
- Tests the structural integrity of components by applying extreme pressure until failure, ensuring safety margins for subsea installations.
Cable insulation testing
- Verifies the integrity of electrical cable insulation under pressure, crucial for subsea power transmission.
Function testing in hyperbaric environment
- Tests the functionality of devices or systems in simulated deep-sea conditions to ensure operational reliabilit
Rapid pressure transients test
- Assesses how equipment withstands sudden changes in pressure, simulating emergency or dynamic operational conditions.
Cost effective
- Hyperbaric pressure testing at NUI is a cost effective way to ensure safety, durability, and functionality of equipment used in deep-sea or high-pressure environments.

In-door testpool
At our facility we can offer a temperature controlled training and test pool (7mx5mx3,5m) with:
- 12t crane for ROV or equipment launch into pool.
- Inspection windows allowing personnel to observe the operation.
- Diving stations that includes hot water, gas and communications. Direct visual observation for supervision of divers through windows.

Subsea Testareas
NUI has established three Subsea test areas in the Close vicinity to the Hyperbaric Reception Facility in Gravdal.
The three test areas has the following dimensions:
- Concrete plattform 20 m (Geopositioned for Acoustic testing)
- 300 m² 90 m depth
- 900 m² 20 m depth (quay side)
Subsea Well
In the Onarheimsfjord, South of Bergen, NUI has established a subsea well for testing and verification of light intervention equipment.
The well in drilled at 115m dept, and is 298m deep. Both wellhead and the steel casing is pressure tested to 5000PSI
