Container ship operators looking for the lowest possible fuel oil consumption at any engine load will be interested to hear word from MAN Diesel & Turbo that the first super-long-stroke large bore two-stroke engine specifically designed for them, the S90ME-C9.2, has just successfully completed trials on Hyundai Heavy Industries Engine & Machinery Division’s test bed.

The new engine, of reduced size for container ship engine rooms (although the largest ever designed by MAN) is based on the VLCC-optimised S90ME-C8 engine, as operators look to reduce operating costs through slow steaming, turbocharger cut out and low-load engine optimisation; all of which are offered by the new engine.

Low-speed two-stroke main engines of MAN’s existing MC type, with a chain driven camshaft, have limited flexibility with regard to fuel injection and exha... [More]
Wärtsilä announce the addition of two new 62 and 72 bore engine series to their RT-flex two stroke, low speed programme. The new engines offer significant benefits to both shipowners and operators by way of high propulsion efficiency, reliability, and optimised total cost of ownership. The two new engine series employ well-proven Wärtsilä low-speed technology, together with electronically-controlled fuel supply and control. Wärtsilä's licensee partners in Asia are closely involved in the manufacturing process and all Wärtsilä licensees will have the right to build the new engines. Availability of the 62 is Sept 2013 and 2014 for the 72. [More]
