Damen PSV 3300: A Diamond in the Rough

Maritime Activity Reports, Inc.

January 6, 2014

The platform supply vessel World Diamond was delivered by Damen Shipyards, Galati, on June 28, 2013, to World Wide Supply. The PSV was built to a completely new and distinctive design from Damen, and World Diamond is the first of six PSVs for the Norwegian owner. The vessel is capable of worldwide operations and its construction involved close cooperation with Damen Shipyards Gorinchem, The Netherlands, which provided engineering and main equipment.
The PSV 3300 represents a new era in Damen’s offshore supply vessel story, having been built to a new design as part of a major extension in the yard group’s offshore portfolio.
The 80.1m PSV 3300 will undertake crew and materials transport to and from offshore platforms but also offers firefighting and oil pollution recovery capability. Equipped with azimuthing thrusters and for dynamic positioning (DP2), the design is distinguished by slender hull lines to meet challenging conditions and minimised fuel consumption, as well as enhanced crew comfort.
World Diamond is the first delivery of the PSV 3300, developed after extensive CFD studies and hull testing at Maritime Research Institute Netherlands (MARIN) to verify the results. Built to Damen’s “E3” principles, the vessel is distinguished by its sleek bow, slender hull lines and diesel electric propulsion with azimuth stern drives. This combination has been developed to minimize slamming and to balance a relatively high cargo intake with low fuel consumption, not only in calm water but also in rough seas. The azimuthing thrusters with ducted propellers in conjunction with the bow thrusters are designed to provide accurate station keeping. The vessel features DP2 capability as well as newly designed anti-roll tanks, while smooth surfaces and a distinct lack of angles, lines and recesses also have a positive effect on the durability of coatings. Other notable features of design include a new sheltered foredeck and an optimized superstructure for crew comfort, while the steel-welded wheelhouse is mounted on top of the deckhouse to ensure an optimal view in all directions.
World Diamond is powered by a diesel electric solution with Tier II-compliant Caterpillar engines; two C3512 generator sets in combination with two C32 TTA generator sets. The gensets are connected to a waste heat recovery system, greatly reducing fuel costs for heating of accommodation, tank cleaning and other purposes. The vessel is provided with a state-of-the-art Integrated Automation System (IAS) that incorporates a redundant topology reflecting the vessels design intent.
