Royal Thai Navy picks MAN 175D to power new patrol vessels

MAN Energy Solutions has won the contract to supply the main propulsion engines for two new 41 meter patrol vessels for the Royal Thai Navy. Each vessel will be powered by two MAN 16V175D-MM, IMO Tier II engines, each rated at 2,960 kWm at 1,900 rpm.

Marsun Shipyard in Thailand will construct the newbuildings, with delivery scheduled for August 2020.

The Royal Thai Navy already operates MAN Energy Solutions engines on its Krabi-class Offshore Patrol Vessels; a second such vessel was commissioned last September.

“We are delighted to expand our presence in the Royal Thai Navy’s fleet with the addition of these two new vessels,” said Barend Thijssen, Head of Four-Stroke Marine Sales & Licensing – MAN Energy Solutions. “The 175D is rapidly establishing itself in Governmental applications, due to its excellent performance and efficient operating costs.”


The MAN 175D engine range includes 12, 16 & 20-cylinder variants, with outputs ranging from 1,500 to 4,000 kW, optimized for propelling ferries, offshore supply vessels, tug boats and other, working vessels.

Specialist model versions have also been developed for other market segments, such as superyachts and naval marine applications.

The MAN 175D is an extremely eco-friendly engine, designed from the outset to comply with the latest, as well as future, exhaust-gas-emission requirements. The engine utilizes a very compact and flexible SCR system, that enables vessel designers to optimise space on board.


Established in 1980, Marsun Public Company Limited is strategically located near Bangkok at the mouth of the Chao Phraya River and has delivered over 300 vessels of various types, including naval and commercial vessels.
