X62-B

The most compact engine in its class of very low shaft speed engines

Designed for vessels with slim hull lines, X62-B offers high propulsion efficiency in a unique combination of low engine revolutions and an engine design with a minimum physical width.

Thanks to the engine’s agility, it is the optimum choice for several vessel segments, like Aframax tankers, Panamax/Kamsarmax bulk carriers, as well as feeder container vessels. For container vessels, the extended layout field offers the possibility to select the optimum propeller speed for a wide range of propeller diameters. The main parameters result in the engine and piston dismantling height being minimised; an essentiality for this type of application where engine room heights are limited.

This 620mm bore engine is available in 5-cylinder up to 8-cylinder configuration, covering a power range from 7,950 to 23,200kW at 77 to 103rpm.

 

OPERATIONAL FEATURES

WinGD’s well proven electronically-controlled common-rail technology plays a key role in enabling ship owners to reduce fuel costs, mainly through the flexibility of the fuel injection and exhaust valve operations. This flexibility results in lower fuel consumption across the entire operating range, especially at low and part loads. In addition, different engine tunings (Standard, Delta, Delta By-Pass and Low Load) are available in order to meet specific customer requirements. Intelligent Combustion Control (ICC) system enables further fuel savings and balanced working of each cylinder. The engine is fully compliant with IMO Tier III NOx emission levels when equipped with a SCR catalyst system. The introduction of the EEDI index also puts an emphasis on CO2 emissions and total vessel efficiency. The X62’s internal engine and propulsion efficiencies, and the possibility to apply various Power Take-Off (PTO) arrangements for on-board electricity production, makes it easier for shipyards to meet these new requirements. Waste Heat Recovery (WHR) offers further possibilities for maximising energy efficiency and for reducing emissions.

TOTAL COST OF OWNERSHIP

All areas of lifecycle costs have been taken into account for the X62-B. The selected stroke-to-bore ratio makes the engine compact and has a positive impact on the manufacturing and component cost. The X62-B is designed for exceptional reliability and for long periods of maintenance-free operation. It also allows extended Time Between Overhaul (TBO) of the critical components, to as much as 5 years. The service-friendly design will reduce downtime, maintain vessel operation, and cut operating costs. Together with Condition Based Maintenance (CBM) and service agreements, the overhaul interval could be even further extended, thus minimising maintenance costs and maximising the revenue-earning capability of the vessel.

DF-READY OPTION

All Generation X engines can be converted to use LNG as fuel. For simplifying the future conversion WinGD has introduced the DF-ready version as an option. The DF-ready engines can be easily converted to dual-fuel, as no major structural components need to be modified. All parts, which are to be replaced at a later conversion, are either typical wear parts or specific X-DF components and systems. DF-ready version is the recommended solution for LNG-ready ships.
