BS Camburi, a 36-meter Monohull Crewboat built in Brazil by Arpoador Engenharia to the Petrobras type P2 specification has been launched and delivered.
 
Designed by Incat Crowther, the 118-foot (36-meter) aluminum crewboat is powered by triple CAT C32 ACERT diesel engines coupled to three Thrustmaster DOEN DJ290 waterjets. Designed to Petrobras type P2 crew boat spec, this vessel will transport up to 70 passengers and crew as well as carry 50 tons of deck cargo plus fuel and fresh water cargo at a fully loaded service speed of more than 17 knots.
 
The Thrustmaster DJ290 waterjets have been specified with stainless steel pump assemblies fitted with 29-inch (737-milimeter) high volume single stage axial flow impellers.
 
According to Thrustmaster of Texas, Inc., the waterjets provide excellent high-speed efficiency with superior cavitation margins, allowing full power application at any load condition and also at zero speed for maximum possible thrust during docking and station keeping maneuvers at sea. Additionally, Thrustmaster’s prefabricated aluminum intake duct installation combines maximum vessel integrity with simple installation.
 
Each DJ290 has its own fully integrated hydraulic system providing steering and reverse control. All of the hydraulic equipment including cylinders hydraulic and associated hose connections are completely inboard mounted. All hydraulic pumps are directly driven from the gearbox PTOs.
 
Vessel propulsion control is managed using Thrustmaster’s CAN BUS – Control system. Configured for triple engine – twin station; the system combines primary control of engine throttle and gear command with the waterjet steering and reverse functions and all necessary monitoring, alarm and backup control functions. The second (rear facing) station has been fitted with Doen’s eDOCK joystick control system. This provides a single joystick lever control that simultaneously actuates and controls waterjets and engines for low speed maneuvering control.
 
The waterjets and control system are supplied to DNV HSCLC R2 CARGO B CREW boat.
