Grainger & Worrall secure marine engine contract

Bridgnorth-based casting specialist Grainger & Worrall is manufacturing the main engine castings for the world’s first 300hp diesel outboard marine engine. The company has been chosen by the engine’s developer and manufacturer, Cox Powertrain due to its ability to deliver flexible programmes in a short timescale with precise quality control. The CXO300 diesel outboard engine is a 4.4-litre, twin turbocharged V8 delivering 480lb.ft torque. It offers increased durability over petrol variants and up to 25% improved fuel efficiency, making it ideal for a range of applications including commercial vessels, leisure and sea rescue.

Grainger & Worrall director, Matthew Grainger, said: “We are delighted to be identified by Cox Powertrain as the ideal partner for its incredible new diesel engine project. The cylinder heads and both upper and lower crankcase will be produced by Grainger & Worrall as the first series production contract for these four significant engine castings. The innovative casting technologies employed by our company make us the ideal supplier for Cox Powertrain’s ambitious programme, which requires its first engine casting deliveries to be made by year end. Our agile, flexible approach is the perfect solution for manufacturers and suppliers working to short timescales who require reduced lead-times without jeopardising quality control.”

Grainger & Worrall has developed a number of innovative casting technologies that are designed to accelerate the time to market of new products by reducing prototype production times and which are supported by its digital simulation, small- to medium-scale manufacturing and engineering capabilities. For example, digital sand manufacture, which is an additive manufacturing process, fuses grains of sand using a traditional printing technique to provide a faster, more flexible production process. The company has also recently invested in a third, larger scale CT scanner to ensure absolute quality control of all manufactured components, bringing GW’s total investment in CT to over £ 1.2m.

Duncan Green, Head of Procurement for Cox, added: “Achieving any world-first requires the support of the best suppliers and all of Cox’s suppliers are carefully evaluated on their abilities. With a product in such high demand as the CXO300, it is important for Cox to partner with a supplier who can provide us with high quality, precision engine castings in the timescales and volumes required.

“With Grainger & Worrall continuing to invest in technologies and techniques that enhance its current capabilities and with a long & proven track record of delivering similar products in to other premium OEMs, it makes the ideal supplier for Cox Powertrain.”

Grainger & Worrall will be producing 70 engine sets per week for Cox Powertrain, which will be distributing through its networks in North America, the Caribbean, Europe, Africa, the Far East and Australia.
