Anatec are experienced in performing risk assessments for North Sea oil and gas operators, enabling them to make informed choices and satisfy Regulators (e.g., BEIS), their consultees (e.g., MCA, Trinity House and Northern Lighthouse Board) and Stakeholders (e.g., SFF and NFFO) when seeking consent for decommissioning projects. We have been operating in this field of expertise since 2001 and our Principals have been at the forefront of the marine hazard analysis and risk management field for the past 20 years. Our research has ensured the risk to maritime stakeholders of options such as leaving platform footings, pipelines, bundles and other subsea structures in place are considered on a case-by-case basis as part of the comparative assessment required by the BEIS decommissioning guidance. This allows for a full reasoned argument for the consent process, tailored to the specific circumstances of the location. We can also assist oil and gas companies in meeting the decommissioning guidelines issued by the General Lighthouse Authorities (GLAs) to meet their requirements during decommissioning and total removal of offshore structures. In consultation with BEIS, all changes to Aids to Navigation (AtoN) will require prior consent from the relevant GLA. This applies to establishment of new AtoN as well as disestablishment or changes to existing AtoN. The application must be accompanied by a Navigational Risk Assessment. Each piece of infrastructure and each phase poses a different risk and hazards can vary according to the different types of maritime stakeholder using the area, for example, free spans would affect fishing vessels but not merchant shipping. Our assessments are able to:
The risk modelling is capable of accounting for the potential challenges of:
Sensitivities can be performed by varying inputs, such as assumed mitigation measures. Assessments are performed using our industry best-practice models, such as ShipRoutes and COLLRISK, which are referenced by IOGP. With regard to the GLA Decommissioning Guidelines, Anatec can prepare a Navigational Risk Assessment (NRA) to assess any changes to Aids to Navigation and/or deviation from the Standard Marking Schedule, for example, during a period of cold storage when solar powered AtoNs may be used. The scope of the NRA must cover the following:
