Waterjets power fast rescue craft
Under full power Bogøy achieves nearly 40 knots.
Innovation AS of Norway has recently delivered a 14.9m rescue/passenger boat to Wold Coastal Transport.
Stationed in Bogøyvœr in Norway, the boat will be responsible for the rescue missions and transportation of patients to and from hospital.
Bogøy is based on a widely proven hull designed by Jon Boye Andersen at Innovation AS and is constructed out of all welded marine grade aluminium alloy. The deep V hull produces a dry, smooth and stable ride which is a necessity for its rescue missions.
Innovation AS selected twin Iveco N67 diesel engines rated at 560 hp and coupled to twin UltraJet 340 waterjets via ZF 280-1 gearboxes to facilitate quick response time in getting to rescue sites and transporting patients living on the islands to and from hospital. Under full power the boat achieves nearly 40 knots. Under normal conditions the engines are derated to 500 hp each, giving 36 to 37 knots top speed, producing only 65 dBa in the wheelhouse at cruising speed. There is on board capacity for 12 crew/passengers.
The boat is also equipped with a hydraulic bow thruster and winch, stern rescue platform and rescue pilot.
In the USA, MetalCraft Marine has delivered the first of eight 26’ US Navy towboats.
Metalcraft Marine was awarded the contract by the United States Navy for the construction of the boats, which will support the US Navy’s spill recovery, support and salvage operations worldwide.
Fully loaded, the aluminium towboat can reach speeds of 34 knots with its single Iveco NEF 450 hp engine, rated at 420 hp, driving a single UltraJet 305HT High Thrust Waterjet via a ZF 280 gearbox. UltraJet waterjets were chosen for their high bollard pull for vessel recovery. During sea trials bollard pull tests achieved 3,800 pounds. Thrust vectoring is with Ultra’s Hydromechanical control system with a single helm lever. The hydraulic power-assist steering provides light and responsive directional control.
