Dear Sir/Madam,

In response to call for abstracts for IRPC 2013, I have pleasure in submitting the following abstract along with other pertinent information:

Title of paper: Mitigating risks from escaping gas/oil to atmosphere in offshore production facilities.

AbstractOpen type off shore production facilities are characterized by the process equipment being accommodated in a relatively small plot area as compared to onshore installations. The close proximity of the process equipment to each other and movement of operating personnel on the platform in case of an emergency poses considerable risks. The likelihood of such risks can arise in case of escape of flammable gas/oil to the atmosphere during the normal course of operation of the platform.  Two cases are considered in this paper having potential of gas/oil to escape to the atmosphere due to deviation of operating parameters from normal, and which can lead to hazardous consequences. The two cases considered are escape of gas through overboard line due to pressurization of upstream equipment, and reverse flow of gas/oil from a high pressure section to the low pressure chemical injection suction tank system. Finally the paper proposes emergency process control measures for the above two cases which can be considered by platform personnel to eliminate the risks. This paper is based on experience gathered on identification of risks and proposed mitigating measures while conducting a hazop studies on offshore platforms/FPSO.

The paper pertains to upstream processing category. I trust you will find the paper relevant to the aspect of process safety, and consider giving me an opportunity to present the paper.

Thanking you,

Dear Sir/Madam,

In response to call for abstracts for IRPC 2013, I have pleasure in submitting the following abstract along with other pertinent information:

Title of paper: How to conduct an effective hazop.

AbstractFor new process plant projects, or revamp/additions to existing projects, it is customary to conduct hazop sessions with an internal multi disciplinary team and external hazop facilitator and scribe. The success of the hazop exercise greatly depends on availability of project drawings and information to the external hazop facilitator. Typically, the documents required are P&IDs (drafted in CAD), PFDs, heat & material balance, operating manuals, control and shutdown philosophy, cause & effect diagrams, plant layout drawings, MSDS, equipment and material specifications etc. It is necessary that only current documents are given to hazop facilitator for his/her preparatory work, and do not undergo changes till completion of the hazop.  The time available for the hazop is generally fixed by the facilities owner. Usually, the contact for conducting the hazop is awarded to Risk Management Company, and the hazop facilitator and scribe are representatives of the Risk Management Company. Availability of the above project documents well in time to the hazop facilitator enables all preparatory work to be completed before the hazop sessions commence, and usually the hazop can be completed within the allotted time. Usually, the only project documents available during the preparatory phase are the P&IDs, which also continues to undergo change till the hazop sessions start. The reasons for this are many, but generally related to work scheduling and completion time by the different agencies involved. However, as the Risk Management Company become contractually bound to complete the hazop within the allotted time, the hazop facilitator has no option but perform under uncertainties  and with less than complete documentation. Having facilitated several hazop sessions, the author shares his experience in this paper about minimum project documents required and certain tips which has helped in completion of quality hazop within the allotted time.
