About this report
Unexploded ordnance and boulders present risks to subsea cables, as well as the operations and equipment required for their installation, maintenance, and decommissioning. Data generated by geophysical surveys undertaken in the planning stages of offshore wind farms form a key part of the knowledge base for risk evaluation and management of these operations - and can cost millions of pounds.
Faults in survey design can lead to the need to repeat surveys, or unexpected damage to equipment. Mitigating these risks is critical to minimise resulting project delays and increased costs.
