NUI is offering the ocean industries with the deepest and largest pressure-chamber facility in Gravdal in Bergen.

This article was first published 8 July 2020.

As a long-leading expert within testing and verification of subsea tools and equipment; NUI makes a new investment in two ultra-deep pressure chambers: one 1000 bar named Asterix and one 700 bar named Obelix.

The names do fit well to the description as Asterix is somewhat smaller in size compared to Obelix (sizes and other information in fact-box below).

The chambers unique design, with supplied test baskets and parking stands, makes the mobilisation and equipment loading into chambers safe and efficient.

The advanced pressure system on both pressure chambers allow customers easily to decide pressure cycling, pressure rates and hold times.

The pressure-set runs automatically with the pre-set data allow for off-site monitoring. Each chamber has several chamber penetrators (18) for control, monitoring and measurements.

Installation about to Start

The installation will start 6 July 2020, right after the ongoing FAT is completed. The official opening of the new chambers is set to 1 September, but the chambers will be ready for customers from 1 August 2020.

By investing in these chambers, we are also positioning ourselves to support the Norwegian and the global ocean space strategy, e.g. deep-sea mining.

As far as we know, Asterix and Obelix are the deepest and largest chambers at their pressure-level and size, and we are very much looking forward to serving our customers.
