Rig Move Attendance

Attendance of an MWS surveyor during a rig move is key to verify that appropriate preparations have been made for the move and check that risks are reduced to an acceptable level in accordance with best industry practice.


The surveyor will perform suitability surveys for the tugs and inspect the towing gear as well as key items of the rig itself (watertight integrity, winches, securing of major equipment, etc.). The surveyor will participate in risk assessment activities, review floating stability calculations, monitor weather conditions and verify adherence to agreed rig move procedures and to the Location Approval, leading to the issue of a Certificate of Approval (CoA) once all preparations have been successfully completed.


We have experienced rig movers who are familiar with the key systems and operations of MOUs supported by an experienced team of structural engineers and naval architects.
