Japan Marine United Corp. just lately delivered the 14,000 TEU container ship NYK Blue Jay to delivery firm Nippon Yusen Kaisha (NYK).

The vessel, which efficiently accomplished sea trials on February 22, is the primary of 10 ordered by NYK for operation on the Asia-European delivery lanes.

The new container ship collection is designed to compete with new technology of extremely massive container vessels carrying round 20,000 TEU by way of working economic system. An superior propulsion idea features a slender dimensioned engine room permitting a hull design with distinctive hydrodynamic effectivity. Another vital a part of the working economic system comes from the newest Wärtsilä model Generation X two-stroke diesel engine. The 9-cylinder Wärtsilä X82 is designed by Winterthur Gas & Diesel in Winterthur, Switzerland.

Winterthur Gas & Diesel designed the Generation X diesel and dual-fuel engines to satisfy ship house owners’ calls for for the bottom complete price of possession (TCO). These are conceived for maximized vessel payloads mixed with low gasoline consumption and emissions and for rational, financial manufacturing by WinGD’s licensees.

“It is designed to enable total vessel efficiency to be optimized by a careful combination of main engine parameters and efficiency, the propulsion system and the ship hull. The capability to run lower engine speed fosters the higher efficiency of larger propellers. We took account of this in the engine design, like the Wärtsilä X82 used in the NYK Blue Jay, by employing higher stroke-to-bore ratios than in their predecessors. This not only facilitates the larger, slower turning propellers but also gives higher engine internal efficiency,” defined Rudolf Holtbecker, General Manager, Business and Application Development.

The dual-rating characteristic is an additional TCO-saving facet of the Wärtsilä X82. The foundation of the dual-rating characteristic of the X engines is WinGD’s ‘flex’ system of electronically managed gasoline injection and exhaust valve actuation, mixed with turbochargers with very vast compressor maps. The refined gasoline injection and valve timing techniques developed by WinGD permits the engine to be optimized for 2 completely different vessel working profiles primarily based totally on adjustments of engine system settings. The proprietor thus has a instrument to simply adapt the vessel pace for various market circumstances, all the time guaranteeing the operation with the very best efficiency and economic system.

“As we have seen in the recent past, ship owners wish to be able to respond to market conditions by having closer control over the fuel costs of their ships. In recent years this has led to owners operating their ships at lower speeds with engines running below their design ratings. With the X engines, the dual-rating option has been introduced to allow ship owners to use their engines either with a low or a high maximum power output, further improving fuel consumption in each operating mode without major modifications,” Mr. Holtbecker acknowledged.
