Due for delivery in April 2006, the vessel will be operated by the Hong Kong-based Shen Hua Shipping Company Ltd .

The new tug has been designed by SDARI, the renowned Chinese Shanghai Design and Research Institute, and is intended primarily for ocean towing. Construction will meet the requirements of the China Classification Society and carry the notation, Ice class B2, CSA 5/5 Tug, CSM, AUTO-0, SCM, CMS.

A twin-screw vessel of 89.9m in length overall, with a breadth of 17.2m and maximum draft of 6.8m, the tug will be powered by a complete propulsion package from MAN B&W. Two MAN B&W 8S35MC, low-speed, two-stroke, heavy fuel, main engines will each produce 8050bhp (5920kW) at 173rev/ min. Power will be transmitted to a pair of VBS1080 controllable pitch propellers of 3700mm diameter via Flender type GUG 1200 gearboxes. Each gearbox also powers an 1160kW/1375 KVA shaft alternator via a flexible tooth coupling. This propulsion system will give the new tug a bollard pull of 188 tonnes and a maximum speed of 16 knots.

An Alphatronic 2000 Propulsion Control System will be installed, with two control stations on the bridge and one in the engine control room. The system includes interfaces to a power management system and a Kongsberg Simrad JoyStick control coordinating the output from propellers, rudders and transverse thrusters.

Wuchang Shipyard was founded in 1934 and subordinated to the China State Shipbuilding Corporation prior to the 1999 formation of the China Shipbuilding Industry Corporation.

It is the largest modern shipbuilding enterprise in inland China. The shipment of engines and propulsion equipment from Denmark to China is scheduled to take place between June and August, beginning with the propulsion control equipment, to match the shipyard installation schedule.
