“In , DNV GL developed the LNG-fuelled VLCC concept Triality,” noted Deng Ling, DNV GL project manager and ship type expert for LNG. Today, DNV unveiled a concept tanker design called Triality, an LNG powered VLCC featuring a hull shape that completely removes the need. A noteworthy project undertaken by Det Norske Veritas, called TRIALITY, incorporates several new and interesting concepts in ship design and.

The avoidance of all ballast water issues with this design is an additional operational benefit of high value and convenience to a vessel operator. Synonyms and antonyms of triality in the English dictionary of synonyms. Read more Show less.

The discharge of ballast water from ships is largely responsible for the spread of invasive aquatic species around the world. A noteworthy project undertaken by Det Norske Veritas, called TRIALITY, incorporates several new and interesting concepts in ship design and operations, with the aim of meeting possible future stricter environmental regulations.

Interesting Concept Design of The Week – DNV’s VLCC concept vessel “Triality” – gCaptain

DNV’s ballast-free design holds the potential for an economically attractive and effective way to address the problem. Meaning of “triality” in the English dictionary. It has several advantages over traditionally fuelled vessels.

This page requires javascript. Also helping are the twin-screw propellers with diameters optimized for low-draft conditions.

Topaz Energy and Marine, a leading offshore support vessel owner with primary operations in the Middle East and Additional capital expenditures in the order of USD 30 million is needed for the additional steel for the hull, the LNG tanks and systems, additional cost for engines and boiler, and cost of the VOC systems and tanks, as well as the cooling systems.

Two IMO type C pressure tanks capable of holding 13 m3 LNG dnnv enough for 25 nautical miles of operation — are located on the deck in front of the superstructure.


The definition of triality in the dictionary is the state of being threefold. The Triality, with a more V-shaped hull, provides full propeller immersion and sufficient forward draft to avoid bottom slamming when unloaded. Triaoity 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.

In mathematics, triality is a relationship between three vector spaces, analogous to the duality relation between dual vector spaces. Triality 2 years ago. Triality is a crude oil tanker concept that is fuelled by liquefied natural gas, has a hull shape that removes the need for ballast water and will reduce considerably emission to air.

The substrate is then broken up into pieces that A team from the Research Department of leading international classification society Bureau Veritas has won the Ballast tanks need to satisfy high coating standards PSPC during newbuilding. Avatars by Sterling Adventures. This is partly carried out through heat exchangers.

ABS, a leading provider of global maritime triiality services, has been named Best Class Society at the In response to the problem, the industry is trying to find cost-effective ways of treating ballast water. You are currently logged in as. All of them are small and operate in the coastal waters of Norway.

It seems that your browser does not have Javascript enabled. For Triality a group of some 30 competent, mostly young people representing a wide set of disciplines was selected. Bythe majority of owners will order ships that can operate on liquefied natural gas LNG. The shipping industry is being challenged to reduce its emissions of SOx, NOx, CO2 and particulates, both by current and incoming regulations and society as a whole.

TRIALITY – Definition and synonyms of triality in the English dictionary

Here is the full press release from DNV on the innovative new design. The new hull shape results in a reduced wetted surface on a round trip and has a lower block coefficient and thus a more energy efficient hull. A VLCC in unloaded transit will normally carry between 80 and tons of sea water containing organisms that can cause damage when released into foreign ecosystems. Another 20 vessels are on order. The design also tries to optimize the propeller conditions.

A ballast-free hull design is therefore very attractive. It could also produce 80 percent less NOx as well as reduce SOx and particulate matter up to 95 percent, while using 25 percent less energy. The cost of maintaining the coating and possibly renewing some steel in the water ballast tanks due to corrosion over the lifetime of a vessel can also be significant. We also share information about the use of the site with our social media, advertising and analytics partners.

The fuel capacity of 13, m3 – or about 6, trialkty – is sufficient for an operational range of 25, nautical miles, which corresponds to a round the world trip. A glycol circuit has been incorporated which will circulate cooling capacity on board almost at no additional cost.

Today LNG as fuel for ships is only available in a trialityy places. Triality 2 years ago in reply to Vanquish The VOC can be either re-circulated into the cargo, or, as suggested in the TRIALITY concept, collected in separate tanks and supplied as fuel to auxiliary boilers producing steam for the cargo pumps or cargo heating.

Because we focus on competence and technology and we do things such as engage in projects like the Viking Lady, the Quantum, Triality and other Load a random word. When loading oil, a conventional VLCC empties its ballast tanks to avoid high bending moments, list or trim. A combination that achieves trjality unique practical, natural, and a people-centric triality that infuses what could be perceived as a familiar aesthetic with a
