A Wärtsilä X40 low speed engine recently passed its Type Approval Test (TAT) in Zhouhai, China, on licensee Yuchai Marine Power’s test bed, verifying that it met all classification society requirements. Sea trials come next and then the new engine will be introduced to the market.

This engine, with its 400 mm cylinder bore, a power output in the range of 4,550 to 9,080 kW and available in 5–8 cylinder configurations, covers the small-bore end of the market. Wärtsilä say that it is ideal for ‘Handysize’ vessels (smaller bulk carriers, product tankers and container feeder vessels) which is a segment where they are making their presence increasingly felt after a number of years absence.

Wärtsilä today announced the addition of a new X92 model with 9,200 mm bore. The X-series features an extra long stroke with reduced engine revolutions allowing a higher efficiency larger diameter propeller to be used. The X92 series is aimed at the market for large and ultra-large container vessels with a size above 8,000 TEU up to to any size under construction and beyond. The first 92 bore engine is planned for delivery in 2014.Power output figures have not yet been released but an estimation would give a value of around 5,200 kW per cylinder for the new engine.

Two six cylinder X35 engines successfully completed the Factory Acceptance Trials last month in two separate facilities, one at 3.MAJ Engines & Cranes, Croatia, and the other at Yuchai Marine Power Co., Ltd. (YCMP), China. The trials were witnessed by representatives of the Classification Society, the shipbuilder, and the shipowner. The new engine series was originally introduced in May 2011 as the RT-flex35, following these good results, the X35 engine series as it is now known, is henceforth available for introduction to the market. It is a completely new engine that, together with the Wärtsilä X40, will cover the small-bore end of the market and fills a gap in a segment where Wärtsilä has not been present for a number of years.
