World First Full Scale 'Ammonia as Fuel' Marine Four-Stroke Engine Test
While there is no consensus on the marine industry ‘fuel of the future’ that will meet ever tightening international emission mandates, a group of organizations has commenced what it is calling the world’s first long-term, full-scale, testing of ammonia as a fuel in a marine four-stroke combustion engine. Wärtsilä, Knutsen OAS Shipping AS, and Repsol, and the Sustainable Energy Catapult Center, have teamed for the effort, as ammonia offers promise as a carbon-free fuel for marine applications…
Electric Voith Schneider Propeller Unveiled
With the new electric Voith Schneider Propeller (eVSP), Voith is pushing ahead with the continuous electrification of its drive technologies. Among the advantages of the new eVSP are high efficiency and the reduction of complexity, since the permanent-magnet synchronous motor is already integrated in the propeller. The complete omission of gears reduces noise to a minimum and frees up critical space on the ship.The drive system combines the technology of the VSP with over a decade of electrical know-how of the Voith Inline Thruster (VIT).

NOx Control: Should Certain Vessels Get a Break?
When it comes to the EPA’s recent proposed delay to implementation of Tier 4 marine diesel engines ‘in certain high-speed commercial vessels,’ where you stand probably depends on where you sit.On September 6, the U.S. Environmental Protection agency (EPA) proposed to delay implementation of Tier 4 marine diesel engines “in certain high-speed commercial vessels.” Specifically; EPA mentions three kinds of vessels: lobster boats, pilot boats and a third, more open-ended reference to “other high-speed vessels,” possibly including hovercraft.
The Drive Behind Water-Cooled Motors
Peter Svartsjö at ABB discusses the benefits of water-cooled motors for marine applications that require megawatt levels of power, including space saving, increased energy efficiency and reduced maintenance needs.Electric motors run several main functions on marine vessels – from propulsion and thrusters to deck handling equipment such as winches, anchors and pumps. This makes them mission-critical for ship owners and operators, as their reliability and performance can have a…
PROPULSION TECH: How to Get to Hybridization
Hybridization in the marine world is transitioning from the latest fad to a key part of vessel design and retrofits. Driven in part by a demand for increased efficiency and new waves of global legislation, hybridizing or electrifying a vessel is quickly becoming necessary for organizations. In fact, the International Maritime Organization (IMO) rules and guidelines for the marine industry call for reduced emissions globally, and some ports around the world have established ambitious…
Wärtsilä, COSCO Shipping Ink EGCS MoU
The technology group Wärtsilä and COSCO Shipping Heavy Industry have signed a Memorandum of Understanding (MoU) covering the development of local production resources, thus ensuring further development and support of Wärtsilä’s exhaust gas cleaning systems (EGCS) in the region. The agreement was signed in June 2019.By combining the experience, expertise and competence of the two companies, both of whom hold strong positions in the marine market, this partnership will create a ‘one-stop-shopping’ service for exhaust gas cleaning systems…
