The Skandi Arctic dive support vessel transports and operates all of the equipment necessary to move, lift, cut, and weld the pipeline sections together underwater. All equipment used for hyperbaric tie-in is thoroughly tested here in the safety of the Haugesund port in Norway before the vessel deploys. The divers on the Skandi Arctic live in a special accommodation that has been pressurised to match the pressure on the seabed where they will work. Between deployments to the sea floor, they rest in their quarters, which resemble a small space station on the vessel.
