European Offshore Wind Deployment Centre, Aberdeen

Critical Electrical Equipment Inspections | Case Study

Project: European Offshore Wind Deployment Centres, Aberdeen

Contractor: J. Murphy & Sons Limited

The gas-insulated switchgear (GIS) at this windfarm protects the wind turbines from overloads and short circuits and is a critical piece of machinery. Instruments located on top of the switchgear must be regularly inspected and maintained, and safe access for on-site personnel is paramount – but site limitations in this instance presented complex challenges which Dura Composites were able to solve.

The shape and size of the unit made it impossible to use usual design methods, so following a consultation with their design team, Dura Composites’ engineers were able to perform an analysis which resulted in the selection of a single heavy-duty handrail and beam to connect two end frames, created from Dura Profile, and support the Dura Grating floor panels.

The finished design had several conflicts with the usual standards used to build plant access platforms, but with their significant design, fabrication and installation expertise, Dura Composites was confident that it would meet the client’s exacting requirements.

A design Risk Assessment was conducted to identify and mitigate any residual risk, and the design was altered to incorporate a self-closing door before being presented for approval.

With approval granted, fabrication could commence, with the Dura Install Team cutting the Dura Grating flooring panels in situ to allow them to fit around the tricky format of the switchgear.

Whilst the end client benefited from the eliminations of residual risk when maintaining the GIS, Dura Composites client J. Murphy & Sons also benefitted from a completed managed package that provided a hassle-free, safe and non-conductive bespoke solution to a complex problem.

The platform was delivered and installed as planned. We’d like to commend your installation team for a proactive approach and professional attitude.

Dura Grating Riser Flooring

Dura Grating is a safe, anti-slip, easy to install and lightweight riser flooring solution. Compatible with our galvanised steel Dura Box our GRP Dura Grating is made from high-strength composite fibreglass and is both non-conductive and chemically resistant.

Available in standard mesh, mini mesh and covered grating versions, Dura Grating offers a safe and robust permanent or temporary protection solution for riser voids in construction.

Dura Boxes

Dura Composites offers a galvanised steel Dura Box shuttering system which is ideal for use in reinforced concrete frame construction to provide an opening for future pipes and services to be installed. The cast in Dura Box is a safer, leave-in-place alternative to post pour fixing and can be pre-fabricated to suit the individual measurements of each riser void.

Unlike timber shuttering, it never needs breaking out and results in less onerous management, with no daily riser inspection register needed. The surface can be fitted with covered, standard or mini mesh Dura Grating to mitigate the risk of falling personnel or debris.
