With CO2 emissions from shipping currently accounting for over one billion tonnes per annum, vessels under the IMO’s (International Maritime Organisation) Energy Efficiency Design Index (EEDI) have been required to reduce their carbon emissions since 2013, graduating to 30% by 2025. In conjunction with this, it was recently confirmed that MARPOL Annex VI regulations, which will see the global limit of sulphur in fuel lowered to 0.5%, will be implemented in 2020.
Further and more widespread environmental legislation is inevitable and clean technology has a critical role to play in driving significant improvements in sustainability. Silverstream Technologies is committed to increasing environmental and operational efficiencies within shipping to reduce GHG emissions and contribute to meeting global warming reduction targets.
Silverstream Technologies is proud to be one of the 16 founding members of the Global Industry Alliance (GIA) to support low carbon shipping. The GIA is a public-private partnership initiative of the IMO under the framework of the GEF- UNDP- IMO GloMEEP, the aim of which is to support the uptake and implementation of energy efficiency measures for shipping, thereby reducing greenhouse gas emissions from shipping.
Glomeep has launched the Energy Efficiency Technologies Information Portal to give comprehensive information on the wide range of ways in which ships can reduce fuel consumption and therefore emissions.
Green Ship of the Future (GSF) is a joint initiative in which companies across the Danish Maritime Cluster join forces to develop and test environmentally and climate friendly technologies that increase energy efficiency and reduce operational costs.
In 2017 Silverstream Technologies collaborated on the Regional ECOFeeder project, a vessel which provides an immediate reduction of CO2 by 30% compared to the average feeder fleet.
The Marine Environment Protection Committee (MEPC) addresses environmental issues under IMO’s remit. Tshi includes the control and prevention of ship- source pollution covered by the MARPOL treaty, including oil, chemicals carried in bulk, sewage, garbage and emissions from ships, including air pollutants and greenhouse gas emissions.
The Energy Efficiency Operational Indicator (EEOI) was developed by the IMO to allow ships to monitor the carbon emissions of their shipping activities. The EEOI is the total carbon emissions in a given time period per unit of revenue tonne-miles. Variations in the index are mainly caused by three factors: the technical efficiency of the ship, the amount of cargo transported per unit of time, and variations in speed. However, as the EEOI is an aggregate number, it is difficult to identify the influence of these factors.
The purpose of the Ship Energy Efficiency Management Plan is to establish a mechanism for a company and/or a ship to improve the energy efficiency of a ship’s operation.
ISO 19030-1:2016 outlines general principles for the measurement of changes in hull and propeller performance and defines a set of performance indicators for hull and propeller maintenance, repair and retrofit activities.
The general principles outlined and performance indicators defined are applicable to all ship types driven by conventional fixed pitch propellers, where the objective is to compare the hull and propeller performance of the same ship to itself over time.
Referred to as MARPOL 73/78 (short for marine pollution 1973/ 1978), the International Convention for the Prevention of Pollution from Ships, 1973 as modified by the Protocol of 1978 is one of the most important international marine environmental conventions. It was developed by the International Maritime Organization in an effort to minimize pollution of the oceans and seas, including dumping, oil and air pollution. The objective of this convention is to preserve the marine environment in an attempt to completely eliminate pollution by oil and other harmful substances and to minimize accidental spillage of such substances.
