GTT AND HUDONG ZHONGHUA RECEIVE JOINT AiP FOR BALLAST-FREE LNG BUNKER CONCEPT

GTT AND HUDONG ZHONGHUA RECEIVE JOINT AiP FOR BALLAST-FREE LNG BUNKER CONCEPT

Monday, July 12, 2021 

French company GTT and partner shipyard Hudong Zhonghua Shipbuilding Group have received a double Approval in Principle (AiP), from China Classification Society (CCS) and DNV, for a 'Ballast-Water-Free' LNG Bunker and Feeder vessel concept.

The received AiPs recognise the compliance of the vessel design with the rules and codes relating to ocean-going vessels, their construction and equipment. The Ballast-Water-Free design fitted with GTT’s membrane system enables the construction of more economical and environmentally friendly vessels.

The majority of merchant vessels worldwide use ballast water when the bunkers are empty or partially loaded in order to maintain seaworthy conditions. Therefore, a considerable quantity of ballast water is carried by ships every day. Even when ballast water is treated, there is a risk of transferring harmful aquatic organisms and pathogens from one area to another. The solution developed by GTT eliminates this risk completely. In addition, removing the ballast water treatment system reduces the energy consumption and CO2 footprint of the vessels.

A ballast-free vessel offers advantages in terms of investment and operational cost, simplification of vessel operation, reduction of corrosion and prolongation of lifetime. An extensive test campaign in the hull test tank has demonstrated the design's sailing and seakeeping capabilities.

Philippe Berterottière, GTT Chairman and CEO, said: “This major technological innovation to improve both the environmental and economic performance of LNG Bunker and Feeder vessel has been made possible thanks to the support of our partner Hudong Zhonghua. We welcome the approvals of CCS and DNV, which allow us to offer our ship-owners and charterers customers a high-value technology solution. GTT once again demonstrates its ability to innovate in order to make vessels ever more environmentally friendly and in line with the environmental guidelines of the maritime industry.”
