4 triAlity vlcc The <strong>Triality</strong> VLCC triality is an innovative concept vlcc that fulfils three main goals: 1. it is environmentally superior to conventional vlccs 2. it has technically feasible solutions 3. it is more economical than conventional vlccs the name triality reflects these three main elements. triality is defined as three united, “the state of being three”. triality is a vlcc that has the same operational range and capacities as other vlccs. three most likely trading routes have been selected for our study, all starting in the gulf. one is to the Us, one is to europe and one is to china: the triality concept consists of different elements. each has been compared environmentally and economically with a base case which represents a conventional vlcc. the first step was the introduction of lng as fuel in a conventional vlcc. the main engine is a high pressure dual fuel ( gas or oil fuel) two-stroke engine, while the generator engines are low pressure dual fuel engines and the boilers are also multi fuel versions. the next step was to introduce a ballast-free more v-shaped hull design in addition to the lng propulsion. the limited draft leads to some changes to the machinery configuration, and a two-propeller arrangement has been chosen. finally a voc re-condensation system and the cooling of the main engine scavenging air were added. each step makes the concept better from both an economic and environmental point of view.
