8 triAlity vlcc LNG as fuel lng as fuel is a proven concept for short sea shipping. now this alternative is being developed for full-scale deep-sea shipping. lng is used for propulsion, power and steam production (instead of hfo). triality will have twin high pressure dual fuel two-stroke main engines using marine gas oil (mgo) as pilot fuel, low pressure dual fuel generator engines using mgo as pilot fuel and a triple fuel boiler that can burn natural gas, mgo and volatile organic compounds (vocs = hydrocarbon vapours recovered from the cargo tank atmosphere). two pressure tanks (imo type c), each of 6 750 m 3 volume, will be located in deck houses in front of the superstructure on the main deck. the lng tanks are kept at a pressure of 5-6 bar by the use of pressure build up heat exchangers. this is sufficient to supply lng to the high pressure pumps for the twostroke main engines without using submerged pumps. pumping lng to a high pressure is much more efficient than using compressors to create an equally high pressure. the lng fuel tank pressure is sufficient to supply lng through the low pressure vaporizers and to the auxiliary engines and boilers without the use of pumps. A submerged pump is, however, included in each tank. this can be used to pump lng out of the tank should the tank pressure be too low. lng export terminals are located relatively close to important crude oil terminals in the gulf area. making lng available as fuel should therefore be a realistic possibility. the lng volume stored on board triality is sufficient for a range of 25 000 nautical miles, so that bunkering in the gulf can provide enough fuel for even the longest round trips. this is standard practice for conventional vlccs today. lng terminals are also close to crude oil import terminals visited on our chosen routes, so in the future bunkering may be possible at many locations.
natural gas is used as fuel for triality’s slow speed main engines, auxiliary engines and auxiliary steam boilers. the 13 500 m 3 lng fuel tank capacity gives the vessel a range of 25 000 nautical miles.
