AiP for ballast-water-free LNG vessel concept

The ballast-water-free design, fitted with GTT’s membrane system, is said to enable the construction of more economical and environmentally friendly vessels.

“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,” said Philippe Berterottière, chair and chief executive of GTT.

“We welcome the approvals of CCS and DNV, which allow us to offer our ship-owners and charterers customers a high-value technology solution,” he added.

A considerable quantity of ballast water is carried by ships every day and, even when treated, there is a risk to the marine environment of harmful organisms and pathogens. The solution developed by GTT eliminates this risk completely whilst also reducing the energy consumption and CO2 footprint of the vessels.

A ballast-free vessel also offers advantages in terms of investment and operational cost, simplification of vessel operation and reduction of corrosion whilst prolonging the lifetime of the vessel.
