Bureau Veritas Marine & Offshore granted an approval in principle for the CUBIQ design, confirming compliance with the most stringent safety and performance standards, according to a GTT statement.
Building on GTT’s recognised expertise in containment system design and advanced sloshing methodology, this cubic-shaped tank offers a breakthrough by eliminating upper and lower chamfers traditionally used in LNG fuel tanks.
GTT said this innovation provides a “straightforward response to ship-owners’ and shipyards’ requirements amid the growing adoption of LNG as marine fuel.”
The LNG containment specialist said the new solution delivers simplified and faster construction, as the standardised cubic geometry, with fewer corner areas, eases installation and can reduce construction schedules by several weeks, offering shipyards valuable time savings.
It also offers optimized cargo capacity and profitability.
With a capacity of up to 14,000 cbm, the design is particularly suited to long-distance container routes.
It also features a pressure build-up capability of up to 1 barg, already approved by classification societies, ensuring compliance with forthcoming cold ironing regulations, GTT said.
18 LNG-powered vessels in H1
GTT received orders for ten LNG carriers, seven very-large ethane carriers, and 18 LNG-powered container vessels in the first half of this year.
Earlier this year, French shipping giant CMA CGM ordered 12 LNG dual-fuel containerships from South Korea’s HD Hyundai Heavy Industries.
The LNG tanks of these container vessels will have a capacity 12,750 cbm.
Moreover, GTT announced a further order received in the second quarter, placed by HD Korea Shipbuilding & Offshore Engineering and concerning the design of 8,000 cbm tanks for six new LNG-powered container ships on behalf of Greece’s Capital.
All of these LNG tanks will feature GTT’s Mark III Flex membrane containment system, along with the “1 barg” design, which allows an operating pressure of up to 1 barg.
