Caterpillar (NI) has appeared before Antrim Crown Court and has fined £7,500 following a fuel spillage at Larne Harbour, in June 2016.
The fuel spillage occurred on in the early hours of Saturday, June 11.
Caterpillar staff discovered the diesel spillage at 7am on 11 June, but initially believed that the spill had been contained within the site.
The company reported the incident to the Northern Ireland Environment Agency (NIEA)
once they became aware that an unknown quantity of diesel had discharged to the Irish Sea.
The Northern Ireland Environment Agency (NIEA) received a report from a member of the public that a significant fuel spill had occurred in the vicinity of Larne Harbour.
NIEA’s subsequent investigation concluded that more than 40,000 litres of diesel had been discharged to the Irish Sea.
The Judge heard that company had put in place a number of additional “fail safes” in respect of the operation of their fuel systems in order to minimise the risk of a similar incident occurring in the future.
