The Ulstein designed SX130 IMR vessels Neptune Despina and Neptune Larissa were named in a joint ceremony on 26 October 2011 at Zhejiang Shipyard, China. Neptune Despina was delivered to shipowner Neptune Offshore on 27 October. The second vessel is to be delivered in mid November.
Ulstein has supplied design, detail documentation and main equipment for these vessels, including products such as main switchboards, bridge and control room consoles, Ulstein IAS (integrated alarm and surveillance system), Ulstein COM and navigation equipment and Ulstein PMS (power management system).
The vessels are 98.6 metres long and 19 metres wide. "Both vessels are equipped with a moonpool and an integrated ROV-hangar and can perform subsea operations like inspection, maintenance and repair in deep water. The vessels have the Clean Design (double hull), comfort class V3 and dynamic positioning (DPII) classifications," says Lars Ståle Skoge, sales and marketing manager in Ulstein Design & Solutions.
The exhaust is released through the ship side close to the waterline, freeing space in the wheelhouse, and allowing for a full, unobstructed 360º view.
Zhejiang Shipyard is part of the Sinopacific Shipbuilding Group. In September, they delivered another Ulstein designed vessel, the platform supply vessel Bourbon Front of the PX105 design.
