The Challenge

Red7Marines, crane barge comprising of 30 x 18m flat top barge Haven Seaforth and 110Ton Eiger crawler crane were supplied to assist in the Jack – Up site moves. This enabled the Jack-Up legs to be removed and stowed on the deck of the barge so that all bridges between Borehole locations could be transited safely and efficiently whilst keeping to a strict time schedule. The project also utilised Red7Marine’s Damen built tug, the Haven Supporter and safety boat the COMIII.
