PARTNERSHIP RESULTS IN NEW GEN WATERJET

HamiltonJet has partnered with complex metal specialist Grainger and Worrall to develop a new generation waterjet with powerful waterjet thrust and efficiency for use in patrol and commercial workboats with engines of up to 570kW power.

To reduce time-to-market, meet customer delivery commitments, and shorten overall product introduction timelines, HamiltonJet partnered with G&W on the production of the first set of (six) production waterjets that were used to launch HTX30 waterjet and were also installed in the first vessels to use the new product.

Richard Reynolds, new product introduction manager at HamiltonJet said, “Our CEO had worked with G&W in a previous role at another company, and with his recommendation we contacted them. G&W’s project and process control met and exceeded our expectations, allowing us to work an extremely compressed schedule and meet all our deliverables.”

Global partnership

The partnership, which spanned from HamiltonJet’s design office in Christchurch, New Zealand, to G&W’s manufacturing facility in Bridgnorth, UK, saw the development of 24 large structural aluminium sand castings comprising an integral part of the propulsion unit.

Working closely with HamiltonJet, G&W used cutting edge Magma simulation technology to ascertain casting feasibility and risk. G&W produced mould packs by additive manufacture using its S-max cold cure sand printing system. The result is the development of large structural components cast in marine-grade high silicon alloy in an eight-week period.

HamiltonJet will be exhibiting at Seawork 2019 on stand Q10 and at VB23.
