Success for Swedish waterjets
A 22-shipset patrol craft order for MJP waterjets from French yard OCEA has resulted in further global orders
Swedish waterjet maker MJP reports several recent significant military orders for its products.
As part of a reinforcement plan by the Indian Coast Guard, MJP has started the first deliveries of MJP 650 DD CSU jets for a total of 36 ship sets in an order from Larsen & Toubro. That order has been followed by an contract with Bharati Shipyard which is building a further new Indian Coast Guard vessel. Both contracts include the supply of interceptors to offer improved ride control. The Bharati vessel is also equipped with rudders to enhance steering control and course stability.
MJP’s expansion into South Africa in 2010 has resulted in several deliveries, with the first MJP-propelled vessel, fitted with triple 970kW engines and 500 DRB jets, reaching 35 knots on sea trials.
During 2010 MJP delivered 22 ship sets based on 500 DRB waterjets to the French Shipyard OCEA. The yard is marketing its design globally, which has fesulted in further orders for MJP. The delivery includes complete GRP intakes bolted to the aluminum structure.
MJP has delivered four ship sets to Israel Shipyard for a Romanian Border Police project. The patrol boats have twin 1,630kW engines, providing 43 knots maximum speed and, says MJP, acceleration to 40 knots in almost half the time achieved by a sister vessel equipped with a competing brand.
For a French landing craft project, MJP has succeeded in achieving steering and reversing control of two jets simultaneously using a central column operating both jets in parallel by means of a single hydraulic control. The vessel is equipped with four engines and four MJP 650 jets, with a distinctive hour-glass shaped Swath hull which enables operation in two modes, catamaran mode and barge mode. MJP employed CFD to optimise the flow in the bucket to enhance the reversing performance.
Due to the limited space inside the hull, the traditional MJP bucket design could not be used so a completely new arrangement was developed with the inboard hydraulics placed above the jets.
