Port of Cork has turned to Castrol Marine to further reduce its environmental footprint and protect the sensitive waters in which it operates. Castrol Marine’s Bio Range of environmentally-responsible lubricants are designed for use throughout a vessel where leakage presents a risk. The agreements cover the use of Castrol BioBar 46, a high specification, environmentally responsible hydraulic oil, which is being used in two key Port of Cork vessels, the Multi-cat work boat M.V. Denis Murphy and the tug boat M.V. Gerry O’Sullivan. M.V. Denis Murphy, one of four vessels of its kind in Ireland, is in high demand throughout Ireland and the UK. Its basic functions include towing, plough dredging, buoy handling and anchor handling.
