Marine Operations
The design of an offshore platform is only possible when the designers know how to install it in a safe and controlled manner at the field out at sea. OVERDICK transport & installation (T&I) services, engineering, contracting, procurement, inspections, management, MWS and Authority interface are based on our extensive experience of planning and managing complex marine projects in remote locations with limited resources. Additionally, OVERDICK offers its T&I expertise for Offshore projects designed by others.
