Environmental technological innovations driven by the evolving regulatory landscape have the potential to provide performance solutions for the next generation of offshore vessels. Future historians may look back at the International Convention for the Prevention of Pollution from Ships, Annex VI (MARPOL) requirements as one of the most important pieces of maritime legislation passed. It sets in motion a series of requirements that change the way vessels are designed and operated. For all practical purposes, the offshore industry may be revolutionized by the confluence of Annex VI requirements which limit the amount of sulfur in fuel oil, limit the amount of nitrogen oxides emitted from the engine combustion process, and reduce CO2 emissions from the combustion of fossil fuels. The economics of alternative fuels such as LNG and the imperatives of operating in Emission Control Areas (ECA) are driving innovative vessel designs. Offshore vessel operators of the world can greatly benefit by adopting green technologies such as renewable energy, alternative fuels, hybrid propulsion and power generation plants, and advanced environmental systems. This paper will outline a number of emission pollutant driven and energy efficiency driven green ship technologies currently being adopted in offshore vessel design, and considers the opportunities this presents for future designs.
