At the end of 2020, there were around 62,100 vessels in the world trading feet, with a total deadweight tonnage (DWT) of 2.03 billion DWT. According to the UN, some 80% of international trade by volume and 70% by value is carried by sea. Globally the maritime sector contributes some 2.5% of the world’s GHG emissions and as other sectors improve this proportion will increase unless action is taken.

But shipping is improving. New limits of sulphur emissions were introduced by the International Maritime Organisation (IMO) in January 2020. Emission control areas are set to increase, further limited emissions. The IMO through MARPOL (the International Convention for the Prevention of Pollution from Ships) has introduced a series of progressive measure including the Energy Efficiency Design Index (EEDI), Energy Efficiency Operational Index (EEOI) and the Ship Energy Management Plans (SEMP). This has been extended to recognise the benefits of energy efficiency measures applied retrospectively to existing ships through the new Energy Efficiency Existing Ship Index (EEXI) and a new carbon intensity calculator.

The tide is turning now and owners, operators, lessors and financial institutions are seeking ways to assess and evaluate competing technologies as applied to their vessels over specific trades. Binnies, with our partners BMT under the VTAS (Vessel Technology Advice and Support) banner, have developed a tested methodology to evaluate the benefits of a range of energy saving systems above and below the water line or within the drive train of ships. By modelling the ships’ particulars with and without a combination of devices across a pre-defined series of trades we are able to evaluate the risk, benefits and energy/carbon savings for the different scenarios. This informs investment decisions and the potential for installation on new-builds or as a retrofit.

Our approach has quantified fuel and carbon reductions on VLCCs, Ro-Ro ferries and bulkers. As legislation ramps up to meet changing legislation and funding requirements (such as the Poseidon Principles) we are ideally positioned to provide an informed and quantifiable comparison of the right technologies for the fleet and respective trades.
