Wärtsilä has received an order from two Singapore-based shipping companies to power six new vessels with Wärtsilä X72 electronically controlled low speed engines.
Upon delivery, the engines will be installed on four container vessels that Pacific International Lines (PCL) has ordered from China’s Dalian Shipbuilding Industry, as well as on two bulk carriers currently under construction by Bohai Shipbuilding Heavy Industry for an unnamed Singapore ship owner.
The first Wärtsilä X72 engine is scheduled to be delivered in early 2014.
According to Wärtsilä, the X72 engine provides enhanced efficiency and fuel consumption performance to offer an improved energy efficiency design index (EEDI).
Compared to conventional marine engines, the new engines offer improvement in fuel consumption, reducing CO2 emissions.
Wärtsilä Ship Power vice president of 2-stroke Martin Wernli said that the new X engines were developed to achieve lower operational costs and better environmental performance.
"Compared to similar vessels that have recently been delivered, the bulk carriers’ fuel consumption can be reduced by approximately five tons per day, while the container vessels can achieve savings of four tons per day," Wernli said.
In May 2011, the company launched its low-speed X-generation engine series with two mid-sized engines, X62 and X72, which are designed for vessels that use mid-size low-speed engines like Capesize bulk carriers, Panamax bulk carriers, Suezmax tankers and Panamax container vessels.
Wärtsilä’s X-series also comprises of the X35 and X40 engines, which serve vessels like small bulk carriers, product tankers, general cargo vessels, reefers, feeder containerships, and small LPG carriers.
In April 2012, the company extended its low-speed X-generation engine portfolio with the addition of the new X92 electronically-controlled common-rail engine, with a bore of 920mm.
The X92 engine is expected to offer fuel savings of 10%.
