Boluda Towage Europe’s tugboat ‘Union Koala’ has been officially certified for compliance with the IMO Tier III standards, on Friday, January 10, 2020; The tug then returned to service during a ceremony at the ABC Tower in Zeebrugge, Belgium.

The Mitsubishi Heavy Industries Marine Machinery & Equipment Co., Ltd. announced its delivery MET Turbochargers for one the largest two-stroke dual-fuel X-DF engine, 12X92DF. Behind the engine's development was the Winterthur Gas & Diesel and responsible for the establishment was the China State Shipbuilding Corporation (CSSC).

Carnival Corporation emitted about 10 times more sulphur oxide (SOx) around European coasts than did all 260 million European cars in 2017, a new analysis by sustainable transport group Transport & Environment reveals. As for Royal Caribbean Cruises, it is second, with yet four times worse than the European car fleet.

DP World Southampton announced the launch of new hybrid equipment that will enable it further reduce its emissions and carbon footprint. According to the port's statement, the new hybrid equipment commenced its operation this week.

SEA\LNG and SGMF launched a study according to which GHG reductions of up to 21% are achievable now from LNG as a marine fuel, in comparison to the existent oil-based marine fuels over the entire life-cycle from Well-to-Wake (WtW). The study also confirms that emissions from SOx, NOx and particulate matter, are close to zero when using LNG compared with current conventional oil-based marine fuels.

Shipbuilder Meyer Turku informed that Costa Smeralda was floated out with traditional ceremonies at the Meyer Turku shipyard, on March 15. The float-out of Costa Smeralda, an LNG fueled 180 000 GT cruise ship, signals the start of the final stage of construction for the ship.

Hapag-Lloyd Cruises announced that it will use low-sulphur Marine Gas Oil on all expedition ships from July 2020. Currently, the company is using MGO in particularly vulnerable areas like the Arctic, Antarctica and Kamchatka. The routes will be managed on the basis an eco-efficient average speed, which aims to reduce fuel consumption by one third.

There have been critical debates on potential solutions for reducing CO2 and greenhouse gas emissions in all sectors. As part of the Paris Agreement, adopted by consensus on 12 December 2015, long-term goals have been set by several countries around the globe to limit the increase in global average temperature in an effort to mitigate the effects of climate change.

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.

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.
