New fuel-ready notations from classification societies are too vague and too varied, according to WinGD chief executive Dominik Schneiter.

Many owners are opting to order newbuildings that have a fuel-ready notation, whether LNG, methanol or ammonia, but occasionally ethane or LPG, meaning they may be able to use these fuels after conversion, but cannot on delivery from the shipyard.

However, they then go to the classification societies and pay to have a fuel-ready notation to demonstrate these vessels are modern and future-proof.
