Floating systems

Atkins has been involved with floating systems since the late 1970s, having been involved in around 25% of the world’s entire fleet of floating production, storage and offloading units (FPSOs).

Today we are proud to continue to be at the forefront of some of the industry’s most pioneering innovations including floating liquefied natural gas (fLNG) production units.

Our design, engineering and analytical works represents genuine state of the art engineering. All phases of asset lifecycle are fully supported from concept and feasibility studies through design development, construction, operation and finally decommissioning and abandonment.

We have experience of a wide range of field development options encompassing monohulls, semisubmersibles, tension leg platforms (TLPs) and spars. Our experience extends to cover the full range of mooring and tether options.

Atkins applies this experience and capability to ensure that each facility meets the requirements for long term operation in harsh environments. To support our integrity management services, we have developed effective techniques that enable us to accurately assess defects and if required, develop the most appropriate repair schemes.

These techniques may also be used at the detail design stage in order to minimise future fatigue issues. Our capabilities extend beyond the hull to cover topside facilities including process, utilities and accommodation modules. In subsea, Atkins offer fully coupled analysis for mooring systems, production and drilling risers.

The above engineering and naval architecture expertise is fully complemented by an appreciation of the risk elements of floating production developments. We work closely with both operating and contracting organisations at all stages of field development and have extensive experience in the safety, process, subsea and environmental aspects of such developments.
