With ever-tightening regulations, you may be asking yourself when the optimal time to change over from HFO to MGO will be in order to be compliant when entering Sulphur Emission control Areas (SECAs)? This depends on the fuels’ specifications, the fuel consumption of the vessel’s machinery and its fuel system layout, as well as temperature change constraints. The Fuel Change-Over Calculator (FCO) from DNV automatically calculates the optimum lead time.
A Ship Energy Efficiency Management Plan (SEEMP) offers a practical tool to help you to manage your ship’s environmental performance and improve its operational efficiency. Furthermore, the IMO has made it mandatory for every vessel over 400 GT to have on board a vessel-specific SEEMP, as required by MARPOL Annex VI, Regulation 22, which entered into force on 1 January 2013. The SEEMP does not need pre-approval, but it will be inspected at the first inspection for the IEE Certificate. When leveraged smartly, this mandatory operational measure can improve energy efficiency by cutting your vessel’s fuel consumption and operating costs.
In 2009, the IMO agreed to new measures to improve energy efficiency in global shipping: the Energy Efficiency Design Index (EEDI) and the Energy Efficiency Operational Indicator (EEOI). For newbuildings, the EEDI aims to stimulate the development of more efficient ship designs and is sure to become an increasingly important design parameter. For ships in operation, the EEOI enables you to measure the fuel efficiency of a ship over time and to gauge the effect of any changes during operation.
ISO 50001 is an international standard representing a framework designed by ISO to assist organisations in improving their energy management. It is a specification for an energy management system that defines requirements for establishing, implementing, maintaining and improving such a system. It enables an organisation to follow a systematic approach for the continual improvement of their energy performance and ultimately leads to a reduction in greenhouse gas emissions.
