Sreejith Offshore Training pack
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?

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.

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.

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

Only you can operate and
maintain safety systems withoutflaws.

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.

barriers are in your installation/s?

To learn about the major accidents that
occurred in your offshore complex to
understand What went wrong?; and
To think about the potential barrier failures
that might exist at offshore installations
which could lead to potential majoraccidents.

Platform Accident Details
Show the accident & near-miss trends (bar
chart) and discuss cause breakdown (pie-chart)
A graph that shows no particular trend (upwardor downward) could mean:
The HSE is not under control;
The HSE performance / accident data collection /
analysis is not proper;
No one knows what will be the future HSE
performance is!

Discuss each of the major cases from the detail reports toexplain: Causes Consequences Risk reduction recommendations Implementation status Any similar accidents occurred?
If there are any photos of these accidents, showthem.

Causes
Examples Inadequate planning / organization;
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.

45/114
Sreejith Offshore Training pack
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 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.

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.

Once the safety systems fail,
there can be major accidents!!!Only you can operate & maintain
safety systems without flaws.
