Sheffield Forgemasters International (SFIL) won the landmark $19 million contract to deliver 11 castings over the next two years that weigh in excess of 320 tonnes each, making them some of the largest individual cast components ever manufactured anywhere in the world.
Manufacture of the giant components has now begun and it will see the production of more than 6,000 tonnes of molten steel, with each casting requiring multiple ladles of steel poured continuously.
Dr Steve Price, managing director of sales at the company said: "This contract is important for Sheffield Forgemasters and for the volume of work it brings to the city. It is also important for the UK, as one of the few countries in the world, and the only country in Europe, with the skills and capacity to produce these ultra-large castings."
The company boasts the largest foundry facilities in Europe and is one of very few in the world able to manufacture such large cast components.
Sheffield Forgemasters has a track record of casting 'firsts' including the largest ever cast nodes for use offshore, created for the Aasta Hansteen Spar platform in 2013.
SFIL has previously worked with SMS Meer, a world leader in the production of metals processing and manufacturing machinery to produce a broad range of technically challenging, ultra-large castings.
