US-based NAMJet recently provided a propulsion solution for Norwegian shipbuilder Westplast AS’s new seismic survey vessel WP950. The vessel is powered by twin 15in TraktorJet TJ 381 water jets, which can propel the vessel to 28 knots and provide 6393lb of bollard pull. The WP950, designed as a global support platform, will also perform streamer cable replacements. To boost performance, the TJ 381 water jets underwent custom modifications, reducing its size by six inches. NAMJet also provided a grease-lubricated bearing pack that will allow the WP950 to run even when it is out of the water. The vessel underwent successful sea trials last October. Orders for nine similarly vessels are expected to be completed 2013/14.
