Replacing corroded grating trapped under equipment skids

Corroded grating on the lowest deck of a gas platform was trapped beneath equipment skids. The skids had been fixed through the grating, so the panels could not be lifted.

A request to replace the corroded grating, with point cloud data, photographs and site measurements, and a call with the client to agree the approach.

Agreed the approach with the operator in two options meetings. The scheme holds the old panels safely, adds bolted stiffening under the deck and fits new panels, without hot work.

Concept calculations, a 3D model and five fabrication drawings, with hold points for site measurement and thickness checks before drilling.

Eurocodes.

Led the options meetings; design, drawings and engineering check.
