Ampcontrol required a 2000yr Abnormal (accidental) Limit State structural check for a RMU enclosure. The RMU enclosure is in a cyclonic region and subject to be designed for wind speeds up to 90m/s.
Cube Offshore did the initial calculations based on a site survey and provided drawings. Wind loading on the canopy structure, overturning and sliding of the skid structure was checked. Bolt specifications were calculated based on the required shear and tensions forces required to keep the canopy structure stable throughout uplift and sliding. Cube Offshore demonstrated the RMU enclosure is sufficient for cyclonic wind loading conditions.
