These two extra car lanes in combination with a hull that is ive metres longer, equals to a 14 per cent higher car intake. Notwithstanding the hull being stretched, the windage area has not been increased. This is mainly attributed to major improvements that have been made to the arrangement of the uppermost deck. The position of the wheelhouses has been lowered. They are no longer towering above the techni- cal areas, but have rather been placed in front of them.

For the main propulsion system, TESO opted for dual-fuel engines and therefore initially looked at LNG. The company gained irst-hand experience from visits to VIKING GRACE and the double-ended BOKNAFJORD. Closer study revealed that from a logistics point of view, LNG was not the best solution. In addition to the supply problem, the ambulance crossings would be in jeop- ardy as TESO understandably planned the complex LNG bunkering operations during the night whilst alongside in ‘t Horntje. Even so, TESO remained con- vinced about the advantages of natural gas as it is a no sulphur fuel that emits zero particulates. CO2 and NOx emis- sions are reduced by up to 20 and 90 per cent respectively, with little or no smoke and smell. An alternative for LNG was found in the form of CNG which in the TESO business case comes at a cheaper cost per MW of power than either diesel or LNG. Although less complex than TEXELSTROOM boasts 462 solar panels the bunkering of LNG, TESO carefully transportation cost.
