(SEATTLE) — Construction has commenced at Snow & Company in Seattle on a 50-foot hybrid research catamaran for operation by the Pacific Northwest National Laboratory (PNNL).
The vessel, designed by Incat Crowther, 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. 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 its research.
The 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 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.
With this vessel, PNNL joins a growing list of operators taking advantage of Incat Crowther’s history of innovation in hybrid and low emissions technologies.
