Procurement Other

On 30 October 2024, the Arven Offshore Wind Farm announced that the flagship 2.3 GW floating offshore wind project had awarded NORN a contract for manufacturing, maintaining, and retrieving moorings to support a passive acoustic monitoring (PAM) campaign. This contract represents a concrete procurement milestone within Arven’s early development phase, focused on enabling detailed environmental monitoring in and around the project area. The moorings form the critical infrastructure for PAM systems, which are deployed offshore to support data gathering over extended periods. Within the broader context of Arven’s survey and monitoring activities, this award underpins ongoing and planned deployment, servicing, redeployment, and eventual removal of PAM moorings around the wind farm area, which are used to gather data on marine mammal activity. By formally appointing NORN to manufacture, maintain, and retrieve these moorings, Arven secured specialist support to ensure that its environmental monitoring infrastructure is robust and consistently managed across the lifecycle of the PAM campaign. This procurement step indicates that Arven is progressing from planning into the execution of enabling works that will inform later design, consenting, and development decisions. The contract aligns with other notices and updates related to PAM mooring deployment, servicing, redeployment, and removal, demonstrating that environmental monitoring is being operationalised through dedicated supply chain agreements rather than treated as a purely desktop exercise. It also highlights the project’s engagement with specialist contractors as it builds out the technical and logistical foundations for future project phases.
