NOVEMBER 24, 2013 — Mitsubishi Heavy Industries Marine Machinery & Engine Co., Ltd. (MHI-MME), has received orders from Hyundai Heavy Industries Co., Ltd. (HHI) of Korea for four Ultra Steam Turbine (UST) plants that will power the four 150,000 cu.m. Moss-type LNG (liquefied natural gas) carriers the shipbuilder is to construct for Petroliam Nasional Berhad (PETRONAS), Malaysia's state-owned oil and gas provider in Malaysia (see earlier story).

The orders, which included an option for additional USTs for four more carriers, mark the first time the MHI group has sold USTs outside Japan.

Delivery is scheduled for 2015.

The four UST plants on order consist of four marine steam turbines and eight boilers. The technology incorporated into the UST was developed by MHI independently. The adoption of a reheating cycle, a field in which the company has a strong track record in onshore commercial power generation plants, results in a near 15% improvement in fuel efficiency compared to conventional steam propulsion plants, making MHI USTs more economical and environmentally compatible.

MHI-MME is currently undertaking the manufacture of USTs for eight ships under construction by MHI.
