Flyndre and Cawdor Environmental Statement Section 6 Hydrocarbon Releases Coastguard MRCC, Aberdeen and the Norwegian Coastguard RCC, Stavanger and between the Norwegian Pollution Control Authority (NPCA) and the Maritime & Coastguard Agency (MCA). Maersk Oil recognises three tiers of oil spill incident (Table 6‐8). Tier 1 spill response is undertaken from the infield resources at the Field System under the command of the OIM. When these resources are insufficient to counteract the oil spill, Tier 2 and/or Tier 3 resources can be sought via the onshore Emergency Response Team (ERT). Tier 1/2/3 Tier 1/2/3 Tier2 Tier 2/3 Response Team OIM Infield Maersk Oil Emergency Response Team (ERT) Oil Spill Response Maersk Oil Crisis Management Team (CMT) Location Function Maersk Oil Emergency Response Centre (ERC), Aberdeen Southampton Maersk House, Aberdeen Table 6‐8 Three tier oil spill incident classification. The main function of the OIM is to; From initial alarm, take charge of the situation and assume role of On‐Scene Commander Be responsible for the initial notification of statutory bodies Notify the Drilling Contractor (onshore). The Maersk Oil ERT is comprised of a group of specifically trained personnel who are available to assist if required in the event of a major incident. The ERT will be lead by Maersk Oil Emergency Co‐ ordinator, be based in Aberdeen and will coordinate the spill response aspects of the incident. The main function of the ERT is to; In conjunction with the drilling contractor, provide support to the offshore response teams Assist in maintaining the safety and wellbeing of offshore personnel and integrity of the drilling rig Directly liaise with the drilling contractor Notify statutory authorities as the onshore notification matrix Mobilise specialist external resource requirements (response and other identified contractors) Authorise the proposed response strategy Directly liaise with the response contractors Authorise the proposed response strategy following discussion Monitor the incident and manage the ongoing response. The Oil spill response is comprised trained personnel whose function is to; Provide contracted spill response services, communicating with Maersk Oil Provide spill prediction modelling On operational matters, liaise directly with statutory authorities Once approved by the statutory bodies to mobilise and directly manage the appropriate aerial and other services Develop an appropriate response strategy and propose to Maersk Oil and the statutory authorities Once approved, liaise with Maersk Oil on the appropriate aerial and operational response Provide situation reports to Maersk Oil and statutory authorities Provide changes of response strategy as the situation develops. The main functions of the Maersk Oil CMT are to; Address the strategic issues that affect Maersk Oil Provide support to Maersk Oil staff and relatives Assist in coordination of media response. Maersk oil have in place a management system to reduce the risk of accidental spills occurring and measures in place to minimise any potential environmental impacts should an accident occur. Potential emergency situations are identified within the environmental aspects register and risk 6 ‐ 18 D/4114/2011
Flyndre and Cawdor Environmental Statement Section 6 Hydrocarbon Releases assessments form a component part of individual Oil Pollution Emergency Plans (OPEPs). Procedures for emergency preparedness and response are detailed in Procedure “Onshore Emergency Response”. Procedures for oil pollution preparedness and response are detailed in procedure “Response and reporting requirements for accidental oil and chemical discharges” and the offshore asset‐specific and drilling OPEPS. These procedures apply for all spills of hydrocarbons and chemicals to sea. The measures are described below; Proposed Control Measures Trained and competence assured drill crew and supervisory team. All OPEP commitments (training, exercises, etc) captured in specific rig audit programme. Robust BOP pressure and functional testing regime. Routine ROV inspections of the BOP on the seabed, as well as visual integrity checks whenever BOPs are recovered to the surface. The wells are drilled with an overbalance which is higher than the customary trip margin, as the mud weights are dictated by shale stability considerations. Higher hazard and risk awareness and understanding in light of lessons learned from the GOM/Deep Water Horizon incident. Enhances sharing of industry best practices via the OSPRAG Work Group. Co‐ordinated industry oil spill response capability. An approved OPEP will be in place prior to any activities being undertaken by the drilling rig. 6.5.2. MANAGEMENT OF WASTE STREAM FROM OFFSHORE / ONSHORE SPILL RESPONSE Since the modelling identifies that no surface oil is predicted to reach the coast, any oil in the water column will be finely disposed, there is virtually no potential for wastes to be generated from shoreline clean up activities. Offshore booming and recovery may be attempted but is not considered essential to preserve sensitive environmental resources. Consequently waste oily water and fouled booms should present a small and manageable issue. D/4114/2011 6‐19
