In just four months, MAN Diesel & Turbo has won contracts for four Chinese dredger newbuildings.
Chinese outfits CHECD, Jiangsu Haixin and Huanghua Port Bureau recently chose MAN medium-speed engines for the new trailing suction hopper dredger (TSHD).
CHECD (CHEC Dredging Company Ltd.) – a subsidiary of CCCC Shanghai Dredging Company Ltd. – chose complete propulsion packages from MAN Diesel & Turbo for their two new 6,500m³ TSHDs.
Each vessel will feature one 6L32/44CR and one 9L32/44CR engines with the latest, flexible, common-rail technology. One of the engines will be dedicated to driving a CPP, as well as a mechanical dredge pump, and is designed to satisfy its demands for constant torque and reliable performance under different operational conditions.
Furthermore, the engines will be delivered as ‘SCR (Selective Catalytic Reduction)-ready’ so as to readily accommodate any retrofit should Tier III operation be requested in the future.
The propulsion packages also include an MAN Alpha Twin screw CP propeller plant – type VBS720-ODF – with AHT nozzles, as well as two MAN Renk RSLV-720 gearboxes. Shipment of both shipsets is scheduled for the turn of 2017/18.
The new CHECD dredgers’ basic design comes from Royal IHC in the Netherlands. The new vessels will be built at the Shanghai Zhenhua Heavy Industry Co., Ltd. (ZPMC) shipyard.
In another boost to MAN Diesel & Turbo locally, Jiangsu Haixin Shipping Heavy Ind. has again ordered two MAN 32/40 engines as part of a propulsion package in connection with a repeat order for an 8,000m³ TSHD, a further sister to an existing series of MAN-powered vessels.
The scope of delivery covers one shipset including a propulsion package consisting of two 9L32/40 engines, an MAN Alpha twin-screw VBS860 CP propeller, single marine reduction RSVL-800 gearboxes from Renk, plus an SCR system that enables the engines to fulfill Tier III. Delivery is scheduled for end-2017.
Jiangsu Haixin will construct the vessels at its yard in China, and MAN Diesel & Turbo will build the engines at its Augsburg plant in Germany.
Huanghua Port Bureau
Huanghua Port Bureau has also chosen MAN engines in the form of two 12V32/44CR units to power a 10,000m³ TSHD newbuilding. Both engines will drive a CPP and have a power take-off for a mechanical dredge-pump drive.
The Port of Huanghua is an artificial, deep-water, international seaport on the coast of Huanghua, Cangzhou Prefecture, Hebei. MAN Diesel & Turbo is working with a partner, Yue On Shipping, on this project to provide the propulsion package, as well as additional expertise.
This order represents the first new dredger for MAN Diesel & Turbo in northern China with the new TSHD being built at CSSC Huangpu Wenchong Shipbuilding Co., Ltd.
