Siem Offshore to Start Round Two of Beatrice Inter-Array Cable Works

Siem Offshore Services’ cable laying vessel Siem Aimery has installed 15 inter-array cables during the first campaign on the Beatrice offshore wind farm in the Outer Moray Firth, Scotland.

The first cable installation campaign started on 10 November. The 15th inter-array cable was trenched on 08 December, a Weekly Notice of Operations shows.

Siem Aimery was supported on the project by the cable support vessel (CSV) Siem Stingray.

The notice said that the two vessels are expected to continue the cable installation works, but without providing any specific dates.

The 588MW Beatrice offshore wind farm comprises 84 Siemens 7MW wind turbines and two Siemens Offshore Transformer Modules which will be inter-connected by 91 x 33kV medium voltage alternating current submarine composite cables, manufactured by JDR.

JDR will also provide Siem Offshore with termination and testing services for the wind farm’s inter-array cable system.
