Radar antenna supports high on a compression tower
Two new radar antennas, part of the platform's vessel collision warning, needed supports high on the compression tower. Earlier modifications to the platform had left few places to put them, so the supports had to be designed around what was there.
A requirement for new radar foundations with calculations, with point cloud data, photographs and site measurements, and a call with the client.
An options study with three options at each location, then a deflection-limited design: a swivelling boom on a fixed post at one location and a clamped platform at the other. Every connection to the existing steel is bolted or clamped, so no hot work was needed.
A concept design report, two calculation packages, 22 fabrication drawings and 3D models.
ISO 19902, ISO 19901-3, AISC 360-22, BS EN 1090-2.
Lead engineer: scope, options, both calculation packages, and the drawing and engineering checks on every sheet.
