Seabed Sampling

NUI provides highly qualified personnel and services for testing of equipment and tools for use under pressure and harsh conditions. Our laboratory and test facility is equipped for testing and analysis of gas, chemicals and equipment.

NUI have developed a new sampler that takes gas tight samples from the seabed to be analysed without being decompressed or in other ways loosing components.


The sampler was originally designed to take samples in in conjunction with manned underwater operations, but is also an expedient tool designed for all sedimentsampling where collecting potential Hydrocarbons/volatile organic compounds (VOC) is of any interest.


Any pollution or contamination in or on the seabed from e.g  drill-mud and cuttings, produced water discharge, crude oil, etc and might seep into the diving bell or attach to the divers gear. Having this pollution or contamination into the diving system could be a hazard to the diver if brought into the divers breathing atmosphere.


The new NORSOK U-100 standard set specific requirements for seabedsampling that includes a requirement to use a sampling technique that allows the gas-tight seabed sampling to be brought to surface maintaining the content of possible contaminants. Previous used methods does not meet the requirements, and there are not established any industry standard for sampling and analysing.

The NUI sedimentsampler meets all NORSOK U-100 requirements and will also be a useful tool for environmental mapping of contamination underwater.

Under you can see a short video form the final testing.  Please be aware that this is the first time the ROV operator are using this tool.
