Regulation 23 of the Pipelines Safety Regulations 1996 requires that before the design of any major accident hazard pipeline is completed, the operator prepares a Major Accident Prevention Document (MAPD). This requirement is in place in order to ensure that any risks posed by a new pipeline project have been properly assessed, and that suitable actions have been taken to minimise the frequency and consequences of major accidents following its completion.

In order for a new pipeline to satisfy the conditions of regulation 23, a MAPD must demonstrate the following:

  1. All hazards relating to the pipeline with the potential to cause a major accident have been identified
  2. A risk assessment has been prepared evaluating all of the identified risks and their consequences
  3. A safety management system that can suitably address and control all the risks has been put in place
  4. Adequate arrangements have been made to audit and report on the pipeline upon completion in order that the safety management system can be updated as required


Overview of Historic Pipeline Incidents

Anatec can prepare an MAPD that satisfies all these conditions. With experience of all aspects of the risks associated with offshore activity, Anatec is well placed to identify the hazards that pose a threat to pipelines.

Once identified, Each of these hazards can then be thoroughly assessed to determine its likelihood of causing an accident and the consequences should such an accident occur. Anatec’s software modelling and historical databases allow for a comprehensive, quantitative where possible risk assessment to be created for inclusion in a MAPD. Risks assessed can include:

  • Corrosion and erosion
  • Manufacturing defects
  • Fishing risks
  • Dropped object
  • Dragged/emergency anchor
  • Weather

Recommendations on a suitable safety management system can then be made. This is based on the results of the risk assessment combined with past experience of successful risk mitigation measures in other projects. A plan for periodic checks of the effectiveness of the system once it is in place can be arranged, along with updated reports and further recommendations.
