New crude oil vessel concept – Triality

Madsen: Triality is superior

A new crude oil concept vessel – Triality – developed by DNV (Det Norske Veritas) experts significantly reduces emissions, the company said at a presentation here.
The 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, it said.
Presenting the concept in Qatar, DNV chief executive Henrik O Madsen said: "Triality 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.
"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.”
Madsen said: "Compared to the traditional very large crude carriers (VLCC), the Triality VLCC will emit 34% less CO2, eliminate entirely the need for ballast water, eliminate entirely the venting of cargo vapours (VOCs) and use 25% less energy.”
