Snow & Company is building a new research vessel for the Pacific


Seattle shipyard Snow & Company has begun building a new 15m hybrid catamaran research vessel to be operated 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 engines. . generators. Energy 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 mix of survey operational modes.

Incat Crowther said it developed a bespoke design that offers exceptional capacity for its size. The vessel’s 28m2 main deck is fitted with an A-frame, jib crane and moveable davit in addition to access to a collapsible swim platform, extracting maximum functionality from the boat. ‘space. A set of stairs provides direct access from the main deck to the upper deck and flybridge, which provides excellent all-around visibility. The vessel can support the research of six scientists in a bespoke layout containing multiple research workstations and convertible sleeping accommodations, providing PNNL with a platform capable of effectively conducting its research.
