The IMR vessel ‘Seven Viking’, that will be co-owned by Eidesvik Offshore and Subsea 7, was launched from the dock hall at Ulstein Verft on Wednesday 17 October.
In her right element, the compact 106.5 m long and 24.5 m wide vessel looks very impressive.
The SX148 design will carry out a multitude of diverse tasks for Statoil, including inspection, maintenance and repair of subsea oil installations, alongside scale treatment and RFO operations. The top speed is 16 knots. The ship has a crew capacity of 90, and capacity to carry a litany of essential subsea tools, thanks to a clever configuration whereby hull space is maximised and equipment is integrated within the large hangar area.
HSE has been a major focus for the project partners, this includes a customized module handling system (MHS) integrated in the ship’s hangar for the safe launch and retrieval of subsea modules weighing up to 70 tons.
All operational personnel are gathered in one area directly above the hangar, with panoramic windows in the control room giving a full overview of this key activity area. Also, the ship has been developed to meet the highest working environment standards. She is a comfort class COMF-V (3) vessel, with low noise and vibration levels. The ship also carries the Clean Design notation.
Environmental initiatives have been taken, including the diesel electric propulsion, which reduces atmospheric emissions, while the ship’s electrical winches mean there will be absolutely zero emissions of hydraulic oil.
