Test and Verification
NUI offers industry-leading test and verification services to ensure equipment reliability and safety in challenging underwater environments.fgh
About
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.
Services
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.
Function testing in hyperbaric environment
Tests the functionality of devices or systems in simulated deep-sea conditions to ensure operational reliabilit
Collapse testing
Tests the structural integrity of components by applying extreme pressure until failure, ensuring safety margins for subsea installations.
Rapid pressure transients test
Assesses how equipment withstands sudden changes in pressure, simulating emergency or dynamic operational conditions.
Cable insulation testing
Verifies the integrity of electrical cable insulation under pressure, crucial for subsea power transmission.
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.
