Hapag-Lloyd Cruises to stop using HFO

Hapag-Lloyd Cruises announced that it will use low-sulphur Marine Gas Oil (MGO) on all expedition ships from July 2020. Currently, the company is using MGO in particularly vulnerable areas like the Arctic, Antarctica and Kamchatka.

Speaking about this decision, Karl J. Pojer, CEO Hapag-Lloyd Cruises, said that it was made to protect nature and the environment.

How shipping industry addresses GHG: Targets set, what’s next?

There have been critical debates on potential solutions for reducing CO2 and greenhouse gas (GHG) 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. In the shipping industry, most recently, the target of a 50% reduction of the Greenhouse Gas from shipping emissions by 2050,...

What is Ship Energy Efficiency Management Plan?

SEEMP Ship Energy Efficiency Management Plan

With the growing concerns over increasing greenhouse gases and consumption of fossil fuels, the maritime industry governing body IMO has already taken positive steps by implementing the Energy Efficiency Design Index (EEDI), which monitors the amount of CO2 and harmful emissions from ships.

The idea of Energy Efficiency Design Index (EEDI) is to improve the hull design and machinery operations and to reduce the CO2 emissions by increasing the ship’s overall efficiency.

However, the SEEM plan...

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.

The natural gas has the unique – compared to liquid fuel, capability to be supplied to engine in either high or low pressure. Depending on the supply pressure, engine runs on Diesel (high...

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

The shipping industry is now more than ever facing a pressing need to improve its environmental footprint. The IMO 2020 sulphur cap aims to promote green practices among the industry. However, 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 (ECAs) and establish a strict limit on their emissions.

W...

Wärtsilä Corporation,  22 November 2018 at 11 am EET – The technology group Wärtsilä will deliver its first ever Wärtsilä 31 engine retrofit to Gardar, a fishing vessel owned by Norwegian Gardar AS, built originally in 1998. After the retrofit is completed, Gardar’s fuel consumption will be reduced by 200,000 litres and NOx emissions by over 88 tonnes annually.

Conducting an assessment of port emissions

In IMO’s latest set of toolkits, the first guide of ‘The Port Emissions Toolkit’, provides guidance for ports intending to develop or improve their air pollutant or GHG emissions assessments.

The Port Emissions Toolkit has been developed under the GEF-UNDP-IMO Global Maritime Energy Efficiency Partnerships (GloMEEP) Project, in collaboration with its strategic partners, IMarEST and IAPH.

The first guide of ‘The Port Emissions Toolkit’: Assessment of port emissions, incorporates the latest...
