Different types of risers are suitable for different field developments. And risers can represent 10 per cent of the cost and 90 per cent of the challenge in a field development.
Our team supports clients with early phase riser and well system projects. We start from concept selection and field development planning, helping operators select cost-effective solutions that are robust and withstand the scrutiny of stage gates.
In the execution phase, we perform riser design and analysis, follow equipment delivery and can support offshore installation.
The risers we design are connected to a range of different hosts (Spar, Semi-submersible, TLP, and FPSO) and are located worldwide (APAC, Brazil, Gulf of Mexico, Guyana, North Sea and West Africa).
We have designed and delivered risers for the different development needs of production, drilling, completion, workover, gas lift and water injection applications.
