Edda Ferd Platform Supply Vessel (PSV), Norway


The vessel, when delivered, will be the most environmentally-friendly PSV in the world

Edda Ferd is the latest platform supply vessel (PSV) to be commissioned into the fleet of Ostensjo Rederi in October 2013. The vessel was earlier launched in October 2012. It is being constructed by Astilleros Gondan at its Figueras facilities in Spain.

The vessel is being constructed as part of the Mindset (Marine Industry Superior Environmental Thinking) programme launched by Ostensjo Rederi in 2011. The programme primarily aims to reduce the environmental footprint on the company's business activities.

The vessel, when delivered, will be the most environmentally-friendly PSV in the world, using 25% to 30% less energy compared to other conventional PSVs.

The vessel is designed to operate in the North Sea. It will serve Shell UK in offshore operations in the North Sea for a period of five years, as part of its first contract.

The vessel won the Offshore Support Journal (OSJ) Environmental Award in 2013 and was also nominated for the Next Generation Ship Award at the Opening Conference of Nor-Shipping in 2013.

Skipsteknisk provided the design of the vessel. Carl J. Amundsen Consulting Marine Engineers and Naval Architects is also involved in the project.

A new propulsion concept for the vessel was used by the owner in collaboration with Siemens, incorporating the latter's BLUEDRIVE PlusC system for fuel efficiency.
