MHI Completes First Unit of "STG System" -- Most Recent Type of "MERS"
A High-efficiency Waste Energy Recovery Power Generation System,
Utilizing Exhaust Gas from Marine Engines

The first STG System will be installed in a container vessel currently being built by Daewoo Shipbuilding & Marine Engineering Co., Ltd. of Korea, and will be delivered to A.P. Møller - Mærsk A/S, a Danish shipping company, in 2011. Celebrating the completion of the first unit, a ceremony was held today at the Nagasaki Shipyard & Machinery Works of MHI.

MHI has already received orders for 38 units of the STG System and at present is also receiving many business inquiries for the same. Many of these orders and inquiries are for use on container vessels, which carry numerous energy-consuming refrigeration/chilling container units. With the successful completion of the first unit, MHI plans to reinforce its marketing activities targeting newly-built vessels.

The STG System comprises an exhaust gas power turbine, an economizer (exhaust gas boiler), a steam turbine, a generator, a reduction gear box and an SSS (synchronous self-shifting) clutch and control system. MHI leverages its technological expertise as a major shipbuilding company handling essential components for marine-use waste energy recovery systems such as diesel engines, turbochargers, steam turbines and boilers for the new, energy-saving STG System.

Going forward MHI continues to develop innovative and environmentally-friendly products and systems enabled by the company's comprehensive technology and know-how, to propose new and better solutions to customers in the shipbuilding market.
