MAN B&W Diesel A/S, Holeby, Denmark has been awarded the contract to supply three 9L21/31 Holeby generator sets as main power source for a new 3,000 dwt diesel electric patrol vessel newbuilding under construction for the China State Oceanic Administration, Beijing. The vessel will also be equipped with a 6L16/24 harbor gen set that can operate in parallel with the main gen sets.
The news follows last month's announcement that MAN B&W power had been selected for a 1,000 dwt diesel mechanical patrol vessel ordered in parallel for the Oceanic Administration. The 1,000 dwt vessel will be built by the Guangzhou Huangpu Shipyard, The 3,000 dwt vessel will be built by the Jiangnan Shipyard, Shanghai, and is scheduled for delivery towards the end of 2004.
Both vessels have been designed by MARIC (Marine Design & Research Institute of China), Shanghai, which is one of the major ship designers in China
The main particulars of the 3,000 dwt vessel are:
Length (wl) : 91.0 m
Breadth : 15.2 m
Draft : 5.0 m
Displ/Cb : abt. 3000 ton
The diesel-electric propulsion plant is based on triple nine cylinder L21/31 MAN B&W medium-speed engines with ABB type AMG 560 L6 alternators, driving two propellers/ podded thrusters, which will be speed controlled via an ABB-supplied DTC frequency converter system.
A total main engine output of 5,635 kW (7,660 BHP) will supply the power for the ship's hotel load and give the vessel a maximum speed of 18 knots and a service/cruising speed of 15 knots.
