Greek Shipowners back limit on main engine power for emissions reduction

In line with IMO’s Initial Strategy for decarbonization of shipping, Greece has come forward with a concrete proposal for a short-term, prescriptive measure to improve the operational energy efficiency of existing ships, to be considered at the forthcoming meeting of the IMO’s intersessional technical group in November.

Methane slip from LNG fueled engines

Mr. Antonis Trakakis, Chief Technology Officer at Forward Ships, talks about methane slips from LNG fueled engines. Mr. Trakakis notes that these emissions are not inherent to the natural gas. The problem lies at the applied heat cycle, making the amount of methane slip depend on the technology of each engine.

Complying with NOx Tier III standards: What you need to know

Already established measures have paved the way for a more environmental-friendly shipping. A key example is the IMO NOx Tier III limits. These limits apply to engines installed on or after 1 January 2016, that are operating in Emission Control Areas and establish a strict limit on their emissions.

USCG: Engine types accepted under MARPOL Annex VI

The US Coast Guard Office of Commercial Vessel Compliance issued a circular to outline how the Coast Guard will enforce MARPOL Annex VI Regulation 13.5.1.2 due to the unavailability of engines needed to comply with this regulation.

Wärtsilä eyes 15% GHG reduction from gas engines by 2020

As part of its efforts to minimize the environmental impact of its products, Finnish technology group Wärtsilä said it has set a target to cut GHG emissions from its gas engines by a massive 15% between 2015 and 2020. The first step towards reducing all emissions is to switch from diesel to gas, says Sebastiaan Bleuanus.

ABS: Requirements on engine NOx emission limit for ships in China

The recent announcement by the Chinese Ministry of Transport regarding the Regulations on the Administration of Domestic Waterway Transport for Imported Ships has raised a number of questions on its impact on marine engines installed on ships navigating domestic waterways in China.

Diesel engines can reduce shipping emissions, report says

The Diesel Technology Forum and the Environmental Defense Fund released a report highlighting the emission reduction benefits that can be offered by the latest clean diesel models. The joint research estimates that replacing older engines in a tug boat with the latest clean diesel model that meets the latest emissions milestones can reduce on average 14.9 tons of NOx emissions per year.

US announces funding to reduce emissions from diesel engines

The US EPA announced the availability of grant funding to modernize the country’s diesel fleet by retrofitting or replacing vehicles with cleaner, more efficient diesel engines. Through its Diesel Emission Reduction Program, EPA anticipates awarding approximately $40 million to eligible applicants.

EEB: States use legal loopholes to hide air quality failure

Nine EU Member States have asked the European Commission for permission to pollute above national limits set in EU law. The requests are criticised in a letter sent to EU Commission from the European Environmental Bureau, ClientEarth, Transport & Environment, AirClim and the Health and Environment Alliance.
