    Major accidents do happen around the world,some of them recent, have caused us to ask if

    they can happen to us and they certainly can!

    We need to ensure they do not happen to us by:

    Re-emphasising our safety management system;

    Updating our existing Field safety Case; and

    Ensuring you all know about it!!

    Why this training?

  • 7/31/2019 5052863 Offshore Safety Case Training Ppt

    Sreejith Offshore Training pack

    What will we learn today?

    The difference between occupational/personaland process safety;

    What is a major accident; What is and what is in an offshore Safety Case; What are the safety barriers / controls/ systems/

    Safety Critical Systems (SCE) that prevent majoraccidents;

    The part we all must play in preventing major

    accidents; and Test our understanding of what we have learned

    through Piper Alpha accident.

    Piper Alpha

    1988 Major fire and explosion

    167 people died

    Caused by PTW failure, PFP flaws and layout issues

    Recent Major Accidents in your

    offshore Field?

    Please include details of major accidents (and near-misses) that occurred in

    your installation/s to tell the participants the need for them to be cautious.

    Include photographs if you have.

    Major Modifications

    List down the major modifications (process /

    marine) that occurred in your offshore

    installation/s in the past 1 year to tell them

    that the risk profile has changed:

    Examples:

    Flare system modifications

    Addition of a hydrocarbon process equipment Change in mooring system

    Addition of gas compression facilities

    What is a safety case?

    Operators of offshore installations want to besure that their operations are safe and do notexpose their people or their business tounacceptable levels of risk;

    Plant modifications, variations on operatingconditions and new ownership mean that the riskpicture is changing; and

    Regulators and other stakeholders ask you tojustify the continuing operation of the installationthrough safety cases.

    Corporate HSE Management System

    Show your HSEMS through a flow chart or a diagram toexplain how periodic risk assessment/s are done to update

    safety case, as part of global sustainability reporting / CSR.

    Offshore Safety Case Update project

    Key steps involved:

    Offshore site visit (to assess the safety

    critical element / barrier performance);

    Risk Assessment (using realistic field

    inputs such as barrier performance to be

    used in QRA event gates in frequency

    analysis); and

    Safety Case update

    Once the safety systems /barriers

    fail, there can be major

    accidents!!!

    Only you can operate and

    maintain safety systems withoutflaws.

    Are these terms too obvious and

    more of a commonsense issue?

    If so, why are we discussing this?

    Discussion trigger: BP Texas findings by Mr. Baker panel.

    Process Safety & Marine Hazards

    Process and Marine Safety Hazards Can give rise to major accidents that can have catastrophic

    effects and can result in multiple injuries and fatalities, aswell as substantial economic, property and environmentaldamage

    Examples of these are: Fires / Explosions Helicopter crash Dropped objects damaging structure or FPSO hull

    Un-ignited gas releases Ship collisions Riser / pipeline ruptures

    Safety Performance OH & PSH

    Performance for occupational safety is

    measured through (eg.) lost time injuries

    (LTI); and

    Performance for process safety is

    measured process safety equipment

    performance, hydrocarbon releases, fires,

    etc.

    The HSE is not under control;

    The HSE performance / accident data collection /

    Flaws in PTW procedures;

    Written job procedure did not anticipate

    contributing factors; Failure to follow known job procedure (s);

    Inadequate training;

    Supervisor failure to identify unsafe condition;

    and Failure to communicate.

    Learning

    If no concrete action is taken to rectify the cause ofthe incident permanently, it might lead to an accident

    next time round History has proven this;

    Accidents could happen even with safety barriers inplace;

    Personnel play an extremely important role in

    promoting safety competency, experience and

    knowledge is important; and We need to ensure that the safety barriers are

    maintained so as to control / mitigate accidents.

    Safety Case-Definition

    Safety Case Origin(post 1988 Piper Alpha explosion)

    UK Offshore Operators, says Cullen, mustadopt this new philosophy on safety,

    producing a Safety Case'. This includes

    continuous hazard assessment over theplant's lifetime, fault tree analysis, which

    looks at all the ways an error could

    develop, and takes account of ways that'human factors' contribute to disasters

    Safety Case Evolution Timeline

    Forthwith: Immediate, at once

    Lord Cullen recommended that the 4 (FEA, ESSA, EERA,SIGA) be carried out

    by the offshore operators immediately before the 1992 safety case regulation

    was released.

    Why Offshore Safety Case?

    Operators of offshore installations want to besure that their operations are safe and do notexpose their people or their business tounacceptable levels of risk;

    Plant modifications, variations on operatingconditions and new ownership mean that the riskpicture is changing; and

    Regulators and other stakeholders ask you tojustify the continuing operation of the installation

    through safety cases. Regulatory compliance is essential to your

    business

    Safety Case

    First SC Regulations came into force in1992;

    Cullen Forthwith studies:

    A Fire Risk Analysis;An assessment of the risk of ingress of smoke

    or gas into the accommodation;

    A review of the ability of emergency systems

    to withstand severe accident conditions; andAn evacuation, escape and rescue analysis.

    (Safety Case) Regulations 2005

    Key changes introduced by the 2005 Regulations include:

    -The requirement for duty holders to send an early design notification,instead of a design safety case, to HSE when establishing a new productioninstallation;-Duty holders are required to carry out a thorough and fundamental reviewof their safety cases at least every five years, or as directed by HSE;

    -The present requirement to re-submit safety cases every three years hasbeen removed (inspectors will be checking to see that safety cases arebeing kept up to date through inspection);-New duties require licensees to ensure anyone they appoint as an operatoris capable of fulfilling their legal responsibilities for safety;-Combined operations safety cases have been replaced by notifications,which do not need HSE acceptance; and-The Offshore Installations (Safety Representatives and Safety Committees)

    Regulations have been amended to extend consultation with safetyrepresentatives to reviewing and revising a safety case, as well as preparingone.

    gas industry?

    Unacceptable level of process safety relateddangerous occurrences especially in relation to

    loss of containment incidents;

    Major hazard industry measured safetyperformance using LTIs!!

    Critical systems deteriorate over time without

    warning until they fail catastrophically; and

    Audits tend to be too infrequent and workplaceinspections focus on personal safety.

    How effective are YOUR safety systems?

    Traffic light system was used to assessthe performance of safety systems;

    Each of the safety systems were assessed

    based on: Critical Maintenance Test (CMT) results;

    Accidents / incidents;

    Maintenance backlogs; andAudit findings.

    Learning

    Concept of Safety barriers in major accidentcontrol; and

    Role of offshore personnel in ensuring

    integrity of safety barriers by monitoringperformance indicators; and

    Performance of safety systems to control

    major hazards cannot be monitored usingLTIs which calls for a shift in focus.

    Key Message

    114/114

    Once the safety systems fail,

    there can be major accidents!!!Only you can operate & maintain

    safety systems without flaws.
