Mobilisation has started for air-dive campaign on Kalstø landfall for Statoil/Gassco.

Work to be undertaken is to replace 4 steelboxes to increase strength of the foundations on the Statpipe culverts. Working depth varies from 0-10 m and is very weather sensitive and therefore complex.

There will be 40 people involved in the operation on  24h basis. Operation is expected to be somewhere between 2-3 months.


Design, purchasing and production of the steelboxes has all been done by SubseaPartner . For dismantling of existing steelstructure a special designed diamond saw is made by Proserv.


Subsea Partner’s primary market is surface supplied air diving as inshore MUO (manned underwater operation) in territorial waters, usually less than 12 nautical mil or 19.25 km from the coast. This market includes docks, harbors, canals, culverts, rivers, estuaries, lakes, reservoirs, ponds, water filled tunnels and tanks.
