Rig Moving

The movement and relocation of offshore rigs is a regular feature of Offshore Marine Operations, and ensuring these are undertaken in a safe, efficient and economically sound manner is a key service offering from LOC. We offer support for rig moving procedures for jack up rigs, mobile offshore drilling units (MODUs) and all other types.
