OR Barrier Management DashboardMintra Competence Days 30.04.14

Do we know the status of our barriers?

A rig or a drillship is a very complex piece of machinery, with many interdependent areas working together.

We should not commence any operations without knowing if safety barriers are in place and functional.

This knowledge depends on information from many various sources.

You wouldn’t drive a car if you knew the brakes were out of order?

Background - Overview

When bringing the Leiv Eiriksson to Norway the Petroleum Safety Authority underlined the regulatory requirements in relation to Barriers.

The consultancy firm SafeTec were tasked with assessing the various areas and operations and identified the 17 barrier functions.

The IT-developers Presight were tasked with developing a dashboard solution for the barriers. Based on input from Ocean Rig Presight designed a tool collating information from Star, OCS and Mintra into a graphic interphase.

Regulatory requirementsThe industry must comply with the requirements in the Management Regulation so that relationships between risk assessments and barrier management are made clear. Robust and specific barrier strategies and performance requirements must be developed. Operational, organisational and technical barrier elements must be highlighted in the risk assessments.

Codes and Standards Ocean Rig Internal Procedures

• ISO 31000 Risk management – Principles and guidelines

• ISO 13702 Petroleum and natural gas industries: Control and mitigation of fires and explosions on offshore production installations - Requirements and guidelines

• NORSOK Z-013 Risk and emergency preparedness assessment

• NORSOK S-001 Technical safety (Ref. 6) • PSA Principles for barrier management in the

petroleum activity

• CO-PRO/8-10: USE OF HES ANALYSIS• CO-PRO/8-12 : SAFE JOB ANALYSIS & RISK

ASSESSMENT• CO-POL-HSEQ: HEALTH, ENVIRONMENT, SAFETY

AND QUALITY POLICY• CO-POL-MMM: MAINTENANCE POLICY

Measuring and verifying performance The regulations specify that non-functioning or impaired barriers must be identified.

This requires the responsible party to establish systems and processes which verify that established barrier functions and associated barrier elements have the intended properties.

This means that routines and practice for verifying conformity with the established context must be in place, along with routines to assess the consequences of changes.

Experience in recent years from serious petroleum-industry incidents, nationally and internationally, shows that substantial improvement is required in operational and organisational conditions.

Norwegian Petroleum Safety AuthorityThe PSA:We will follow up in 2014 that the industry acquires a better understanding of the interaction between operational, organisational and technical elements in barriers. We will help to strengthen the industry’s work on producing-life extensions, and contribute to industry collaboration and experience transfer between the players. During 2014, we will give particular emphasis to well integrity and control, hydrocarbon leaks, the integrity of structures and marine systems, the early phase of development projects, and the uncertainty and knowledge dimensions in risk assessments.

Occupational accident vs Major accidentOccupational accident Major accident

• Simple causation• Generally limited consequences• Single barrier breach

• Complex causation• Potentially catastrophic consequences• Multiple barrier breaches• Potential for spread/escalation

Identify potential hazards and accidents Identification of potential hazards and accidents must be carried out with a sufficient degree of detail, in order to identify all the situations which a specific barrier element could play a role in.

In most cases, this means that identification must take place at an area level (by fire area, for instance) and that the assessment covers:

a) all incidents which might occur in the specific area and b) incidents occurring in other areas which could expose the specific area.

For certain types of hazard, it could be more appropriate to adopt an exposure perspective and not necessarily an area one.

SeventeenIdentified Barrier Functions

BF01: Prevent well control problem

BF02: Prevent blowout

BF03: Limit size of HC leaks

BF04: Prevent ignition

BF05: Prevent escalation due to fire or explosion

BF06: Prevent fatalities during escape, evacuation and rescue

BF07: Prevent and limit damage to external environment

BF08: Prevent fire in well test area

BF09: Prevent dropped objects

BF10: Prevent damage to subsea equipment and pipelines

BF11: Prevent toxic release

BF12: Prevent non-hydrocarbon fires

BF13: Prevent loss of structural integrity

BF14: Prevent reduction and re-establish stability

BF15: Prevent helicopter accidents

BF16: Prevent and limit impact from ship collision

BF17: Prevent loss of and reestablish position

Structure of barriers

The term barrier function e.g. “avoid ignition” or “keep contained”, is used to explain the role of the barrier, i.e. risk the barrier is to mitigate.

Barrier functions are fulfilled by defined barrier elements e.g. “gas detectors”, “procedures” or “manually shut down”,

Barrier elements are classed into three groups:

Technical: e.g. Deluge system

Operational: e.g. Helideck familiarisation

Organisational: e.g. Fire team certification

A barrier function will almost always consist of a number different barrier elements.

STAR

‘Star Information & Planning System’ (IPS) is Ocean Rigs Computerized Maintenance Management System.

Star consists of several integrated modules used for the administration of Maintenance & Repairs, Spare-parts & Logistics and QHSE Events & Issues.

Overdue PMs and Corrective work orders for Safety Critical Elements are linked to the Barrier Dashboard.

Important to ensure correct entry of data.

Use of ‘Barrier Verification Jobs’ in Star:In order to ensure that all Systems & Equipment (Technical Accounts) which (by the Performance Standards) are defined as Safety Critical Elements, Scheduled Jobs which cover the defined Verification Activities are made and coded with the words BARRIER VERIFICATION added to the initial Job IDs. These verification jobs may be combined with long term class, or major overhaul jobs, or created solely for barrier verification.

The Barrier Dashboard will monitor all ‘BARRIER VERIFICATION’ ‘Sch. Jobs’ and ‘Planned Maintenance Work Orders’, and will count and display all such jobs which are not completed within the ‘Due Date’ specified in Star:

The affected Barriers will be displayed as threatened in the dashboard.

OCS

Ocean Rig uses the HR-management software OCS to monitor mandatory training.

Training matrix indicates organisational barriers.

Certificates relevant for barrier functions are fed to the dashboard.

In addition OCS feeds the dashboard with crew rotation, indicating status on board at present date and in future.

Quality of data in OCS is essential for indication in dashboard. Missing certificates will indicate impaired barrier function.

Mintra Trainingportal

System for managing internal training and competence.

Training in Mintra identified as relevant to Barrier Functions is transferred to Dashboard.

Deficiencies in relation to set benchmarks will be highlighted in dashboard.

PreSight

Company tasked with developing the tool for harvesting information from management systems.

Based on information from QHSE, Technical Support, HR and Training & Development.

Web based application, visualisation only. No information is stored in the dashboard, updating the mother systems will change the output.

The dashboard is updated every 24 hours.

Displaying the status of barriers

Colour coding All measured elements have defined standards.

Green = Function at or above benchmarkYellow = AcceptableRed = Not functioning

A red barrier element will influence the status signal for the barrier function.

A red light does not mean that operations cannot be executed, but it highlights needs to repair the barrier.

Function, element, measurement

Measurements are aggregated toward the top level.

If a Safety Critical Element signals as red the whole barrier function may be signalled as deficient.

Depending on importance, deficient barrier elements may render the entire barrier function as deficient.

Aggregation into AreaBarrier functions may be aggregated into Areas.

6 different areas have been defined:

• Living Quarter• Helideck• Drilling area• Open deck• Pontoons and columns• Machinery spaces• Well Test Area

Dashboard displays status for Areas.
