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.

Revolutionising condition monitoring to protect the bottom line

The practice of condition monitoring has developed significantly over the last decade, argues Mr. Larry Rumbol, Marine Condition Monitoring Manager at Parker Kittiwake, explaining that Reagentless Testing is now here today. This new form of condition monitoring best practice has the capability to measure a variety of parameters and equipment, bringing a sophisticated monitoring capability onboard.

Stena Line considers using battery power to its fleet

Stena Line signed a contract with Callenberg Technology Group for batteries with a capacity of 1 MWh which will be installed on Stena Jutlandica which operates between Gothenburg and Frederikshavn. The battery power in port operation will start before summer.

Interview with Martin Penney, BMT Smart

SAFETY4SEA Team met Martin Penney, Sales and Marketing Director, BMT Smart at Posidonia 2016 for an interview on how Big Data may benefit vessel performance

Energy efficiency optimisation in practice

George Dimopoulos, Principal Research Engineer, DNV GL Maritime gave a presentation focusing on ‘’Energy efficiency optimisation in practice’’ during the 2016 SMART4SEA Forum. He explained DNV-GL’s approach and experience on assessing and improving the energy efficiency of ships in practice. He highlighted how important is to ensure quantification and insight to both systems and operations for the efficiency of maritime assets. He also presented DNV GL’s computer-based framework COSSMOS and its application to produce tangible efficiency improvements to both newbuildings and ships in service.
