LNG expanding its role as fuel for OSVs

摘要

A pioneer in applying dual-fuel (DF) technology to marine engines, Wartsila continues to extend its references with a programme embracing 20DF, 34DF and 50DF medium speed designs. With respective bore sizes of 200mm, 340mm and 500mm, these engines cover an output range from l,000kW to 19.3MW to address a wide range of applications in the offshore market. Over 1,000 Wartsila DF engines delivered by October last year had accumulated more than seven million operating hours. In addition to OSVs, Wartsila DF installations are serving or projected for LNG carriers; tugs; floating production, storage and offloading (FPSO) tonnage; ferries and inland waterway vessels. One of the largest plants powers the new P-63 FPSO vessel entering service offshore Brazil, whose W50DF machinery is the first to exploit gas-fuelled engines in producing more than 100 megawatt electrical (MWe). The installation can run on treated well gas or treated crude as well as on marine diesel oil (MDO).
