Project Assurance Framework for Capital Project of a Petroleum Refinery

- A Process Safety Approach

Bejoy K. Bharatiya

DNV Germanischer Lloyd

The petroleum industry has long since recognized that certain risks are involved in the major hazard industries. It becomes a major challenge to minimize risk by comprehensive project assurance/audit framework in the project execution of a major process facility in the hydrocarbon industry. Over the years, the oil and gas industry has learned lessons from a number of process safety events and various hazards such as loss of control and loss of containment top events that could result in: fires, vapour cloud explosions, toxic and asphyxiant exposure, which occurred in various parts of the world and are not limited to the country of origin. The design and operation of process facility for the refinery and petrochemical complex have been the subject of major hazard to the oil industry.

It has been the continuous effort of the industry to update the design and operating philosophies to improve the inherent safety of the processing units. The present paper is concerned with defining the major safety considerations of international oil companies, and Industry Standards in designing and operating the refinery and petrochemical process facilities. Inherently safe design and structured project assurance and audit program are mandatory to guide and drive the design intent of HSE critical systems. The main safety philosophies include: ESD and blowdown, fire and gas detection, toxic gas (H2S) detection, active and passive fire protection (including guidelines for firefighting systems and fire protection), layout HSE philosophy, process safety and containment etc.

This paper provides the assurance/audit framework for a major project but does not attempt to cover in detail every aspect of safety design. Reference should be made, therefore, to specific discipline philosophies and specifications as appropriate. (Refer to Figure 1).

Project audit or assurance program shall be applied throughout all the project development phases, engineering, construction, start-up, and operation via dedicated and well-structured efforts. The safety philosophy, and resulting protection of persons and assets, is combining all provisions undertaking during all project phases. (Refer to gated process, 1-6 Steps explained below).

HSE Design Philosophies

During the detailed engineering, and subsequent construction and commissioning, particular care will be taken by achieving:

·         Good engineering practice

·         Application of an all-encompassing QA system

·         Development and implementation of a safety management system

·         Design reviews at 30%, 60% and 90%, layout review, HAZID, Design Safety Review (DSR), accessibility reviews and other reviews.

·         Qualitative and quantitative risk assessments and IPF review

·         Design of installation for extreme weather conditions

·         Execution of an extensive pre-start up review of the plant before introduction of feed (Hydrocarbon, gas) covering both hardware and, control systems and procedures.

·         Conformity check with local regulations, project standards and other applicable industry standards and directives.

Figure-1 Gated Process for Project Assurance/Audit Framework for Project Execution

Project Assurance Review/Audit is required at all stages of project execution.

1.       Pre-Financial Investment Decision (FID) stage:

1)      Management: review critical contractor’s capability, business license, & project experiences, PEP, schedule.

2)      QA/QC: review critical contractor’s ISO 9000 certificate, QA/QC plan, standards/policies/procedures (SPP), sample check of work records/reports etc. (see Table-1 International Codes and Standard)

3)      HSE: review critical contractor’s ISO 18000 certificate, project HSE plan, SPP, sample check of work records/reports etc.

4)      Technical: review Feasibility Study, Environmental Impact Assessment (EIA) reports., compare     critical design area engineering standards against international standards as well as best industry practices, etc.

Deliverable: review comments or audit findings

2.       Front-end Engineering Design (FEED) Stage:

1)      Management: review critical contractor’s capability, business license, & project experiences, PEP, schedule

2)      QA/QC: review critical contractor’s ISO 9000 certificate, QA/QC plan, SPP, sample check of work records/reports etc.

3)      HSE: review critical contractor’s ISO 18000 certificate, HSE plan, SPP, sample check of work records/reports, including PHAs/HAZOP/QRA etc.

4)      Technical: review FEED engineering design, & risk assessment e.g. HAZID, HAZOP, QRA, etc.

Deliverable: audit findings on Statement of Review for FEED, Statement of Review for FEED Safety Study.

3.       Detail Design Stage:

1)      Management: review critical contractor’s capability, business license, & project experiences, PEP, schedule

2)      QA/QC: review critical contractor’s ISO 9000 certificate, QA/QC plan, procedures, standards/policies/procedures (SPP), sample check of work records/reports etc.

3)      HSE: review critical contractor’s ISO 45001 certificate, HSE plan, standards/policies/procedures (SPP), sample check of work records/reports etc.

4)      Technical: review Detail Design engineering design, design variation, & risk assessment e.g. closeout of HAZOP recommendations, etc.

Deliverable: review comments or audit report on Statement of Review for Detail Design, Statement of Review for Detail Design Safety Studies.

4.   Procurement Stage:

1)   Management: review critical contractor’s capability, business license, & project experiences.

2)   Technical: review specifications of safety critical equipment and QA/QC process.

3)   Engineering requirement e.g. specification, database, drawings etc.

(1).         Manufacturing documents e.g. drawings, inspection & test plan, witness Factory Acceptance Test (FAT), review FAT report & Manufacturing Databook/Spare parts, etc.

(2).         Inspection & Test Organization documents e.g. Inspection Report, 3rd party certificate etc.

Deliverable: review comments or audit findings.

5.   Construction Stage:

1)   Management: review critical contractor’s capability, business license, & project experiences, PEP, schedule, etc.

2)   QA/QC: review critical contractor’s ISO 9000 certificate, QA/QC plan, standards/policies/procedures (SPP), sample check of work records/reports etc.

3)   HSE: review critical contractor’s ISO 45001 certificate, HSE management system, plan, procedures, standards/policies/procedures (SPP), sample check of work records/reports etc., construction environmental monitoring, waste treatment plan, emergency response plan

4)   Technical: compare critical design area project engineering standards against international standards, review construction methodologies, check list, punch list, site construction/safety/environmental/QA/QC activities, design variation, mechanical completion, handover report etc. (see Mechanical Completion Certificate Checklists for conducting site audits

Deliverable: review comments or audit report, Statement of Review for Construction

6.   Pre-Commissioning & Commissioning Stage:

1)   Management: review pre-commissioning & commissioning plan schedule, integration plan etc.

2)   Technical: review pre-commissioning & commissioning plan, isolation list, punch list, Site Acceptance Test (SAT), red-line markup drawings, design variation, witness pre-commissioning & commissioning activities, Prestart-up Safety Review (PSSR), ready for startup inspection etc.
