WinGD debuts VCR technology on NYK Line newbuilds
WinGD has announced that the first commercial installations of its new variable compression ratio (VCR) technology will be carried out on two new dual-fuel LNG powered vessels being built for NYK Line.
A 95,000 dwt bulk carrier being built at Oshima Shipbuilding Co.,Ltd. and a 7,000 CEU pure car and truck carrier (PCTC) being built at Shin Kurushima Dockyard Co.,Ltd will be the first two-stroke powered vessels that can dynamically optimise combustion depending on the fuel being used – delivering improved emissions, fuel economy and fuel flexibility.
VCR technology was introduced in June after more than a decade of co-development with Mitsui E&S DU (MESDU). The simple hydraulic solution mounted on the piston crosshead represents a breakthrough in two-stroke engine design as the first concept enabling compression ratio to be adjusted, delivering significant greenhouse gas emissions reductions in both diesel and gas modes (around 6% and 3% respectively).
