Offshore vessel designer, Offshore Ship Designers (OSD), says going green is no longer just an expensive option, and it is no longer just about containing noxious emissions and oil spills. A global focus on carbon dioxide emission reduction means that going green is both a challenge and a business opportunity for offshore service vessel (OSV) operators. Writing in its regular newsletter Design Waves, Neil Patterson, managing director of IMT Marine Consultants, part of OSD, says, “The public wants cuts in greenhouse gases, and has zero tolerance for marine pollution. Expect to see oil companies responding by going green across the board. There are already signs that oil companies will give preference to chartering ships which produce fewer carbon emissions.
