Maintenance Activity While the Wellhead Tower under Live Condition

Abstract

Abstract In response to the "Call for Proposal" for ADIPEC -2012, I'm pleased to submit a paper proposal for Managing Risk in Simultaneous Operations (SIMOPS) under Maintenance/Integrity/HSE/Operations Technical Categories for your consideration. Simultaneous Operation is defined as parallel operation of two or more activities e.g. drilling and production at the same time. Occurrence of this kind of operation exposes the parties to variety risks which due to their interaction. As a result parties before executing the activities meets and studies the mitigation factors taking into account ADMA-OPCO levels of safety.Considering a high production tower we utilize the full measures of SIMOPS. Nevertheless, this type of operation is not the case always for drilling. Maintenance campaigns were jobs under live conditions are executed, for that reason the oil tower needs to be shutdown and SIMOPS concept indeed essential to re-commission the tower. Planning SIMOPS is time consuming due the measures needed to start such operation; the arrangements should contain F&G systems, Deluge system, production crew, panic bottoms on rig floor and the company representative beside other items. Finalizing the HSE audit takes more time. This measures delay the tower commission for a while accordingly losses in production occurs. Managing risks was excellent approach in making the SIMOPS operation much more efficient for our operation is profitable for the company I work for. The results were unprecedented indeed. We managed to shorten time of SIMOPS preparation, comply with the HSEQA regulation, reduce shutdown period of WHT accordingly gain more production, apply maintenance activities and reduce the time of the maintenance barge on-site. This technical paper will introduce our SIMOPS concept of managing risk during maintenance activities and present a case study of a similar case handled previously.
