Energy efficiency ranked as most impactful for shipping in next 10 years

During its latest Annual Summit in Hong Kong on 3-4 October 2018, the Global Maritime Forum presented its Global Maritime Issues Monitor 2018 report, in which maritime leaders ranked ‘energy efficiency’ and ‘choice of emissions reduction strategies’ as most likely to influence the sector in the next 10 years.

Hamburg to accommodate eco-friendly power supply technology

Innovative technology will be developed in Hamburg to enable large and very large container ships to switch off their auxiliary diesel supplies during lay time and draw the power for on-board operations from a mobile generator. Namely, Becker Marine Systems, Hapag-Lloyd AG and Hamburger Hafen und Logistik AG have been testing the new technology as part of a joint pilot project.

Stena Line eyes AI on ships to reduce fuel consumption

Hitachi Europe Ltd., a subsidiary of the Tokyo-based technology company Hitachi, has partnered with Stena Line, one of the largest shipping companies in Europe, to implement artificial intelligence technology on ships to reduce fuel consumption costs, in a bid to boost the company’s efforts to minimise environmental impact.

Monaco accedes to MARPOL Annex VI

Monaco has acceded to MARPOL Annex VI, the IMO treaty covering emissions from ship exhausts and energy efficiency. The instrument limits the main air pollutants contained in ships exhaust gas, including sulphur oxides and nitrous oxides, and prohibits deliberate emissions of ozone depleting substances.

Digitalisation to enable stronger sulphur enforcement

Digital solutions and data sharing are likely the key to better enforcement of the 2020 sulphur limit: Working under EfficienSea2, Danish company Litehauz has developed a solution for ships, similar to ”black box” on airplanes, able to transmit sulphur emissions data to the ships’ owner as well as relevant authorities on land. 

Hull cleaning can improve ships’ energy efficiency

A new paper addresses the impact of periodic hull cleaning on oil tankers concluding that periodic hull cleaning leads to a significant reduction in the daily fuel consumption and hull cleaning energy efficiency effect is greater when the vessel is sailing laden rather than in the ballast condition.

Energy efficiency in shipping: Why it matters

Improved energy efficiency in shipping means use of less fuel, leading to less harmful emissions to the environment. In this context, IMO is leading the Global MTCC Network initiative, funded by EU, with Maritime Technology Cooperation Centres built in targeted regions promoting technologies to improve energy efficiency in the maritime.

Wallem’s experience with energy saving systems

Hong-Kong based Wallem Ship Management shared best practices with respect to energy efficiency on ships, including energy saving systems onboard that reduce environmental footprint, as well as energy efficiency management, such as weather routing or trim optimization.
