Four decades of experience with offshore platforms

Ramboll has substantial global experience with offshore platforms. Since the 1970’s, we have been involved in major development projects and modifications covering topsides, jackets, bridges and modules.

Our multidisciplinary service portfolio for offshore platforms covers the entire project life cycle from early phase studies and detailed design to modifications, lifetime extension projects, revamps, tie-ins, maintenance, process improvements and offshore decommissioning. 

Our services within offshore platforms cover:

Early phase studies and detailed design for greenfield projects

By performing comprehensive early phase studies, our specialists develop feasible offshore platform concepts, including cost-effective platforms for marginal fields and offshore substations for wind farms.

We can provide precision weight and cost estimations for all types of platform projects, enabling our clients to make informed investment decisions.
