Seattle shipyard Snow & Company has started building a new 15m hybrid catamaran research vessel for operation by the Pacific Northwest National Laboratory.

The Incat Crowther designed vessel will be powered by an advanced parallel hybrid-electric propulsion system, consisting of two Volvo Penta D8-510 main engines, capable of producing 374 kW each, supplemented by two Danfoss Editron EM-PMI375-T200-2600 motor-generators. Power is stored using a state-of-the-art Spear Trident battery system, allowing the vessel to operate quietly in a zero-emission electric state while engaged in a mixture of survey operational modes.

Incat Crowther said it has developed a bespoke design that offers exceptional capability for its size. The vessel’s 28m2 main deck is equipped with an A-Frame, boom crane and movable davit in addition to access to a foldable swim platform, extracting maximum functionality from the space. A set of stairs offer direct access from the main deck to the upper deck and flybridge, which affords excellent all-round visibility. The vessel can support the research of six scientists in a tailored layout containing multiple research workstations and convertible sleeping arrangements, providing PNNL a capable platform to efficiently carry out their research.
