23 Degrees Renewables lands nearshore trenching contract for Scottish offshore wind farm

The project work scope included trenching and burial works on three 225kV submarine export cables and associated protection pipes for an offshore wind farm, utilising 23D’s tracked Subsea Trencher system.

The approximate lengths of cable burial in the nearshore area were around 2km per cable from the cable landing, leading offshore. The project also included the de-burial of some anchors and rock bags on site.

The 23D tracked Subsea Trencher system incorporates and deploys field proven subsea technologies to deliver efficient, cost-effective post lay trenching and burial of subsea power, telecoms and flexible products to water depths of up to 600 metres.

The jet trenching spread was mobilised from the ‘Green Isle’ Multicat vessel berthed at Montrose Port’s North Quay.

This is one of many contracts secured after the recent acquisition announcement of 23D by the OEG Group at Global Wind Offshore in London in June.
