Hornsea Project Three Offshore Wind Farm

Received 11 July 2018
From ConocoPhillips (U.K) Limited (ConocoPhillips (U.K) Limited)


ConocoPhillips (U.K.) Limited (“COP”) as a consultee of the Hornsea Project Three Offshore Windfarm, has considered maps, plans and associated documentation for the proposed project. COP, as Operator and one of the owners of assets in proximity to the proposed Hornsea Wind Project Three offshore development, wishes to register as an interested party to take part in the examination of the application for Development Consent of Hornsea Project Three Offshore Windfarm.

COP’s Southern North Sea portfolio comprises operated and non-operated assets located onshore and offshore, including platforms, gas pipelines, a condensate pipeline and a gas terminal located at Theddlethorpe. COP wishes to register the following key concerns as a stakeholder:

? - COP must be able to fully consider all possible implications and ensure satisfactory mitigations are in place for the continued safety and integrity of COP pipelines and infrastructure. Offshore locations and physical contact points of proposed cables crossing the COP owned and Operated pipelines and piggy backed methanol lines are required. Crossings of COP pipelines should be kept to a minimum through bundling or other appropriate methods where possible.

? - There should be no impediment to access to COP facilities that may compromise or complicate decommissioning activity.

? - Collision Risk Management - The impact of displacing shipping is uncertain, however traffic is likely to increase proximate to our assets. This has a number of significant implications to COP’s existing Marine Operations arrangements including the Radar Early Warning System (REWS) and Emergency Response and Rescue Vessels (ERRV). COP expects Hornsea Project Three to agree that it will have an obligation to procure a mitigation solution, if required, to identify the extent of the risk to the Collision Risk Management System, REWS and ERRV, and suitable and proportionate mitigation measures to ensure that such systems are not impaired by the construction and operation of Hornsea Project Three.

? - Potential crossing/proximity issues - COP must be able to assess the proximity of wind farm construction and maintenance operations to infrastructure as well as any construction or maintenance vessels, to determine the requirement for any additional protection measures.

? - Crossing Points should be designed such that the crossing angle be as close to 90 degrees as possible with a 300mm physical separation between the cable and pipeline at the midpoint between anodes to minimise the potential for adverse mechanical loads and electrical interference with the pipeline CP system. To preserve Cathodic Protection and minimise interference, a minimum 50m proximity zone is required to ensure the safety of COP pipelines.

COP is willing to act reasonably and enter into commercial discussions with Orsted in good faith. The execution of crossing/proximity agreements is required to appropriately address all the important issues raised in this consultation including those outlined above. These agreements require review and acceptance by the other infrastructure owners, on behalf of whom COP operate.

Please note that concerns raised at this time are based on headline issues currently captured. Further concerns may be raised following review of technical detail as it becomes available.
