DNV -
The introduction of a new crude oil tanker concept that is fuelled by liquefied natural gas, has a hull shape that removes the need for ballast water and will almost eliminate local air pollution. This concept vessel also recovers hundreds of tons of cargo vapours on each voyage and represents a major step towards the new environmental era for the tanker shipping industry.
The new crude oil concept vessel, named Triality, has been developed through a DNV innovation project. As its name indicates, it fulfils three main goals: it is environmentally superior to a conventional crude oil tanker, its new solutions are feasible and based on well known technology, and it is financially attractive compared to conventional crude oil tankers operating on heavy fuel oil.
DNV CEO Henrik O. Madsen, who presented the new concept in its VLCC version in London today, says: “I am convinced that gas will become the dominant fuel for merchant ships. By 2020, the majority of owners will order ships that can operate on liquefied natural gas (LNG). As a leading class society, DNV has an important role to play in finding more environmentally friendly solutions for the shipping industry, and I’m proud of what has been achieved for the crude oil tanker segment through this innovation project that we are presenting today.”Less harm to the environmentThe Triality concept VLCC has been compared to a conventional VLCC. Both ships have the same operational range and can operate in the ordinary spot market. Compared to the traditional VLCC, the Triality VLCC will:emit 34% less CO2
eliminate entirely the need for ballast water
eliminate entirely the venting of cargo vapours (VOCs)
use 25% less energyLess harm will also be caused to the health of people living close to busy shipping routes and ports as NOx emissions will be reduced by more than 80% while emissions of SOx and particulate matter will fall by as much as 95%.
