Anders Andreasen, senior research engineer at MAN Diesel & Turbo in Denmark, describes how emulsifier development enables water-emulsified light distillate fuel for reducing nitrous oxide emissions in large marine engines.

Friedrichshafen-based ZF Marine, in conjunction with Dutch company HRP (now ZF Marine Krimpen) has secured a contract with Aberdeen-based global shipping and energy firm, the Craig Group, to supply retractable azimuth thrusters…

Environmental lobby groups are pressing the shipping industry, and its regulators, to move away from traditional oil-based lubricants which are causing significant harm to the global marine environment.

A new type of steam engine has been developed in the USA that could see coal - or oil - fired steam power returning to the sea, writes Dag Pike.

Demands for higher efficiency, lower emissions and fuel restrictions are prompting designers to look at high speed diesel-based prime mover options, by Dag Pike.

Concerns over the extent and pace at which LNG will become obtainable as a marine fuel, and shortcomings in the international bunkering network, make dual-fuel (DF) machinery rather than pure gas engines…

All electronically-controlled ME engines in MAN’s two-stroke range are available as ME-GI dual-fuel versions, incorporating high pressure gas injection arrangements, writes David Tinsley.

Thruster manufacturer Brunvoll has released details of the first propulsion application for its azimuth rim driven thrusters, on a Norwegian ferry operated by Fjord1 MRF.
