The engine range was launched in Shanghai on Monday ahead of the opening of Marintec 2019.
The range, starting with the X52-S2.0 and X62-S2.0 and their dual-fuel counterparts X52DF-S1.0 and X62DF-S1.0, feature a short piston stroke that is ideal for vessels with a shallow draught, small propeller diameter or low main deck height.
On the new X62-S2.0 and X62DF-S1.0 engines, the piston stroke has been reduced by 413mm compared to the standard X62 and X62DF– offering a substantial saving in the engine room height needed for installation.
The new engines will be installed in vessels with lowers design draft, smaller propeller diameters and lower main deck height as for container feeders, ro-ro and con-ro vessels, multipurpose vessels and vehicle carriers.
“Our new short-stroke engine series offers a tailored solution for smaller vessels that still require the efficiency and power of two-stroke marine engines. Many of these vessel types are part of an aging fleet that means we expect significant fleet renewal – and a big opportunity for our new engines – over the next few years,” said Volkmar Galke, global director, sales WinGD.
As well as making the engines more compact, the new stroke-to-bore ratio also reduces manufacturing and component cost. Along with design improvements to reduce maintenance and cut operating costs, the new liquid fuel engines will be fitted with an integrated selective catalytic reduction (iSCR) system.
They will be among the first engines to offer the new, compact solution to meeting IMO Tier III NOX limits.
“Both the iSCR and the short-stroke series highlight our commitment to simplifying engine installation for shipyards and therefore reducing costs for owners and operators,” said Galke.
The first of the new engines, a six-cylinder version of the X62-S2.0 engine, will be tested at the end of 2021. The first X52-S2.0 engine will follow six months later.
