The vessel is designed to meet the high demands of IMR, survey, and light construction in some of the harshest environments. The versatility of the vessel allows for RFO operations, scale treatment and light diving support services. Equipment and skidding system are integrated in a large hangar area.

After delivery in 2013, the vessel started operations in the North Sea under a five-year contract with Statoil (now: Equinor). Planned tasks included inspection, maintenance and repair of subsea oil installations, alongside scale treatment and RFO operations.
The vessel's X-BOW® design reduces motion in transit and increases stability in the potential five-metre swells that can characterise the North Sea. Despite this stability, which is usually associated with size, the SX148 design is crafted to be compact. This nimbleness, enhanced by a top speed of 17 knots, allows the 'Seven Viking' to manoeuvre easily in confined spaces and access difficult-to-reach areas.
Although restricted in size, the vessel is not limited in its capacity to carry a range of essential subsea tools and personnel, thanks to a configuration that maximises hull space and integrates equipment within the large hangar area.
