October 2011 www.sname.org/sname/mt Triality is the result of a fast-track innovation project. During a period of 9 weeks, a project team of 30 engineers, representing the full range of concerned disciplines, was challenged to develop a concept very large crude carrier (VLCC) with three main objectives, and to compare it to a baseline conventional VLCC newbuilding of today. e three objectives are improved environmental perfor- mance, technical strength and feasibility using known and proved technologies, and economic attractiveness. Triality ful ls these three main goals. It was not the intention with Triality, nor was it possible within the tight time schedule, to prepare a complete specification for the ship. The concept study should identify relevant solutions and produce sufficient evidence that the conclusions were solid. A complete specification will need to be prepared by a shipyard or ship designer and be tank tested for hydrody- namic characteristics. An innovative answer to upcoming environmental regs BY TORILL G. OSBERG, JAN KOREN, AND TONY TEO The improved environmental per- formance for Triality targets primarily emissions of SOX, NOx, particulate matter, and oil cargo vapor (volatile organic com- pounds, or VOCs). It eliminates the need for ballast water treatment and produces a reduction in emissions of CO2. DNV and many others have, in previous studies, identi ed a number of additional means of improving energy e ciency and thereby further reducing CO2 emissions, and these complement the Triality innovations. e operational range, speed, and cargo- carrying capacity for Triality should be the same as for the baseline VLCC. e trading pro le of Triality is typical for many VLCCs loading in the Middle East Gulf and operating in the spot market. In this way, costs associ- ated with passing through canals or trading in emission control areas (ECAs) are compa- rable between Triality and the baseline VLCC. In the next decade, the shipping industry will face signi? cant tech- nical, operational, and associated economic challenges as a result of upcoming environmental regulations for emissions and ballast water treatment. Development of new ship concepts can be an attractive way to respond to these challenges. DNVs Triality concept vessel features several innovative ideas for a VLCC, including the use of LNG as the ships fuel.
