This paper describes a cost-effective approach developed by Arthur D Little to enable companies to identify the potential safety and environmental hazards of existing facilities, quantify the risks and develop risk mitigating measures. The paper highlights the differences in the approach needed for existing facilities compared with that normally used for safety assessment at the design stage. It shows how an effective audit can indicate very rapidly whether the situation is fundamentally safe or whether there are serious deficiencies which will require a high level of effort to correct.
Safety is of paramount importance in the design and operation of offshore drilling, production and storage facilities. Hazard identification and risk assessment are well established techniques used principally at various stages of the design, to ensure that facilities are operated and maintained safely throughout their life. The approach developed by Arthur D Little and described in this paper, enables companies to identify the potential hazards of existing facilities, quantify the risks and develop risk mitigating measures.
WHY IS SAFETY ASSESSMENT OF EXISTING FACILITIES IMPORTANT?
An incident on an offshore platform or associated facility has the potential potential to cause:
. Injury to personnel.. Equipment loss or damage.. Environmental damage.. Significant loss of income to the operator.
During the design stages, risk considerations are normally based on assumptions about the way in which a facility is expected to be operated and maintained. Over a period of time, many changes will be made to physical systems, equipment, operating procedures, maintenance procedures physical systems, equipment, operating procedures, maintenance procedures and emergency plans. Periodic audits are necessary to check that the safety of the platform or other facility has not been compromised by such changes or by the general deterioration of hardware or by the misuse/abuse of procedures. To meet this need, Arthur D Little developed the approach which is described below.
