HYDROCARBON RELEASE PREVENTION
Major Accident Hazards and Safety & Environmental Critical Elements
Slide2What will this presentation help us understand?
What Major Accidents are and the hazards that cause them
What are Safety and Environmental Critical Elements (SECEs) and why it is important that we manage and maintain them
Slide3Working in Hazardous Environments
Everyone needs to know the hazards associated with the work environment
All areas of a site have specific hazards that have potential to kill people
Understanding these hazards is vital
Slide4Major Accident Hazards (MAHs)
Examples of Major Accident Hazards include:
Fire
Release of hydrocarbons
Loss of well control
Toxic gases
Loss of buoyancy / structural stability
Collisions (helicopters, vessels)
Slide5Major Accidents
Major Accidents are defined as:
Death or serious injury due to fire, explosion or dangerous chemical release
Major damage to structure or plant (
inc.
a well blowout)
Collision of ship or helicopter with the installation
Failure of diving operations’ life support systems
Any other event involving death or serious injury to 5 or more people
Slide6Examples of Major Accidents
Slide7Major Accidents
How do we prevent a Major Accident?
If the worst does happen, how do we minimise the danger to personnel?
Slide8Prevention of Major Accidents
set standards and expectations through management processes and procedures
PROCESS
establish a good organisational culture (i.e. the values adopted, the way people behave and the functions they perform)
PEOPLE
provide suitably designed and constructed plant. Maintain this plant to a suitable condition
PLANT
Slide9Barriers to Major Accidents
Slide10Safety and Environmental Critical Elements (SECEs)
SECEs are key plant and equipment which help avoid an incident occurring or, if it does, help reduce the impact of the resulting accident
A list of SECEs on each offshore facility can be found in a document called the ‘Safety Case’
The Safety Case is periodically updated and a copy can be found with your OIM or electronically
SECEs keep us safe!
Slide11Examples of Safety and Environmental Critical Elements
1. Hydrocarbon containment (prevention)
2. Gas / flame detectors (detect)
3. Drilling well kill system (control)
4. Temporary refuge integrity (mitigate)
5. Lifeboats (TEMPSC) (rescue / escape)

For each SECE there will be a Performance Standard (PS) which sets the minimum level of operation of the SECE
Slide12How do we know these SECE meet their Performance Standards?
Each SECE must reliably perform its function to the requirements defined in its Performance Standard
Maintenance Routines ensure that SECEs continue to perform to their PSs
Inspection and testing routines assure us that SECEs work when we need them
Slide13Independent Competent Person (ICP)
or Independent Verification Body (IVB)
An ICP is appointed by the Duty Holder to double-check our SCEs are working
This is a legal requirement
Who is our ICP?
Checks undertaken by an independent body to ensure that our SECEs are fit for purpose
Slide14Summary of processes which keep us safe from Major Accident Hazards
Slide15Slide16What can we do?
Recognise
that we work in a Major Accident Hazard environment
Familiarise
ourselves with hazards and SECEs on board our installation
Ensure these SECEs are maintained and corners are not cut in the maintenance of this vital equipment
Ensure defects are reported and rectified
Slide17Four points to take home
Major Accident Hazards can potentially cause deaths or serious injuries
Safety Critical Elements (SCEs) are essential to prevent major accidents occurring
These SCEs must meet Performance Standards which are checked by us and by an Independent Competent Person (ICP)
Everyone
is contributing to making and keeping the worksite safe
