Environmentally friendly green technological innovations driven by the evolving regulatory landscape have the potential to provide performance solutions for the next generation of ships and offshore vessels. The International Convention for the Prevention of Pollution from Ships, Annex VI (MARPOL) requirements has become one of the most influential pieces of maritime legislation passed setting in motion a series of requirements that change the way vessels are designed and operated. The shipping and offshore industries are being 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 liquefied natural gas (LNG) and low sulfur fuels and the imperatives of operating in Emission Control Areas (ECAs) are driving highly innovative vessel, system, and equipment designs. For vessels with operating profiles best serviced by hybrid type plants, operators can greatly benefit by adopting environmentally friendly green technologies such as renewable energy, alternative fuels, hybrid propulsion and power generation plants, and advanced environmental treatment systems. This paper will outline a number of these advanced green ship technologies currently being adopted in ship and offshore vessel design and considers the opportunities this presents for future vessel designs.
