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).

Flow Batteries Tested For Zero-Emission Marine Propulsion

A new project, FLO-MAR, has attracted funding from MarRI-UK’s Clean Maritime Call to assess the feasibility of using flow batteries in vessels to enable zero-emission marine propulsion and auxiliary power. Four UK organizations will work together on the project to investigate how the design of electric and hybrid ships, from ferries through to tugs and wind farm vessels, can be optimized to accommodate flow batteries and to assess the advantages this technology offers in comparison with existing lithium-ion batteries and hydrogen fuel-cells.

EPA Tier 4: Difficult and Contentious, 12 Years and Counting

When it comes to complying with EPA’s Tier 4 emissions regulations, there’s no shortage of creativity emerging from America’s maritime engineering firms. Companies such as Hug Engineering are offering flexible, customized aftertreatment-based control systems that can assemble almost in modular like fashion. Other companies, such as ABB Group, offer battery-hybrid power sources to complement combustion power and avoid threshold diesel emissions. Engine manufacturers, such as Cummins…

New MAN Fluid Monitor for Lube Oil

MAN Energy Solutions launched a monitoring device for industrial lube oil.The MAN Fluid Monitor for lube oil is a light and robust system developed to meet the needs of the owners of industrial installations where lube-oil quality is a critical setting. It is said to enable owners to actively monitor – on an ongoing basis – the degradation and contamination of lube oil and protect their industrial assets. The fluid monitor immediately detects even the tiniest anomalies in the lube-oil systems of four stroke engines…

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…

PROPULSION: ‘Power’ to the People

Interstate-McBee brings affordable aftermarket replacement parts to a marine sector thirsting for new ways to bolster the bottom line. As freight rates, subchapter M and the advent of EPA Tier IV requirements all impact the market, an affordable overhaul of an existing engine is one way to find real relief. A recent report, entitled “Impact of Updated Service Life Estimates on Harbor Craft and Switcher Locomotive Emission Forecasts and Cost-Effectiveness,” found the average Category 2 workboat remains in service for 50 years…

BY THE NUMBERS: Replace your Workboat Engine (now)

New Research Doubles Service Life Estimate of Marine Workboat Engines, Reveals Big Opportunities for Diesel Emissions Reductions.It turns out that commercial workboat engines are staying in service more than two times longer than predicted by the U.S. Environmental Protection Agency (EPA), according new research from the Diesel Technology Forum (DTF) and Environmental Defense Fund (EDF). That says a lot for the quality of marine engines, but at the same it isn’t necessarily a good thing.
