Why our tension decks?

Our experience in the specification and design of riser systems, combined with our extensive structural engineering expertise, means we’re able to design bespoke tension decks that not only meet offshore requirements, but offer an improved level of operational flexibility and accommodate the needs of modern jack-up drilling.

An intelligent approach

Whether installing tension decks on new-build rigs or designing a new tension deck for an existing offshore rig, Aquaterra Energy is able to offer a design that is simple and efficient, both economically and operationally.

The size and capacity of the tension deck will depend entirely on the capacity of the rig and your offshore requirements. We have extension experience of the provision of tension decks and have produced concepts and final fabrications for decks ranging from 300TE – 1,500TE tension capacity.
