The vessels have an overall length of 83.4 metres and a beam of 18 metres and a deadweight (dwt) of 4,000 tonnes. The vessels are equipped with the most modern solutions for DP2 (dynamic positioning), oil recovery and fire-fighting. The ships are recognised as medium-sized PSVs and have a cargo deck of approximately 850 square metres and under-deck capacities well suited for the intended operations. They can accommodate up to 30 persons, and are being built according to IMO's SPS code for Special Purpose Ships. In addition, the vessels will be prepared for the installation of an AHC Crane with up to 67 tonnes capacity and an ROV mezzanine deck, which means the vessels can easily be configured for IMR (Inspection, Maintenance, Repair), ROV support, trenching and light subsea construction work.
At the announcement of the design contract in 2014, Per Ivar Fagervoll, CEO in Golden Energy Offshore, said that: "Golden Energy Offshore is a fully integrated ship owning company located in Ålesund, Norway, with all management functions in-house. We look forward to work through and complete this project together with the yard and ULSTEIN. In addition to design, ULSTEIN also delivers a significant package including equipment, supervision, commissioning and testing, which has been instrumental and a condition for us to enter into this series of vessels. There is also other Norwegian equipment on-board including the accommodation interior package, delivered in accordance with Norwegian standards."
The vessels for Golden Energy Offshore (GEOFF) are modern, high-spec, medium-sized PSVs based on the proven PX121 design. They have excellent station keeping capabilities, very low fuel consumption and enhanced environment profile.
