As part of the Emerald floating offshore wind (FOW) project, Green Rebel Marine will undertake a geophysical site survey campaign in the North Celtic Sea from Wednesday 13 to Sunday 31 July, weather allowing.

Survey operations will be conducted by the research/survey vessel Roman Rebel (callsign 2ICA5). The survey will utilise multi-beam echo sounders and ultra-high-resolution survey equipment.

Geophysical equipment will be both hull-mounted and towed. Typically, the towed cable lengths will be approximately 35m from the vessel while acquiring survey data.

The work will be conducted on a 24-hour basis continuously until completion, subject to weather and logistics. During operations, the Roman Rebel will display the appropriate day shapes/signals and lights as required by the COLREGS.

A continuous listening watch will be maintained on VHF Channel 16 and Digital Selective Calling (DSC).

As the survey vessel will be restricted in its ability to manoeuvre, all other vessels operating within this area are requested to keep their distance and pass at minimum speed to reduce vessel wash.

Coordinates of the survey area and contact details can be found in Marine Notice No 47 of 2022, attached below.
