Main Port Engineering was awarded £650,000 from the Welsh economic growth fund in March 2015. The funding was granted to assist with a capital investment of £1.627 million for a new purpose-built facility in the Haven Waterway enterprise zone. The terms and conditions linked to this support were fully met at the time by the company. The company entered administration following a winding-up order by Her Majesty’s Revenue and Customs, and were affected, no doubt, by the Murco oil refinery closure in 2014, which was one of their main customers.
