Mintra 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
We should not commence any operations
without knowing if safety barriers are in place
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
The 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

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 Authority
We will follow up in 2014 that the industry
acquires a better understanding of the
interaction between operational,
organisational and technical elements in
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 accident
Occupational accident Major accident
• Simple causation
• Generally limited consequences
• Single barrier breach
• Complex causation
• Potentially catastrophic consequences
• Multiple barrier breaches
• Potential for spread/escalation
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
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.
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 Information & Planning System’ (IPS) is

for the administration of Maintenance & Repairs,
Spare-parts & Logistics and QHSE Events &

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
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.

software OCS to monitor mandatory

Certificates relevant for barrier functions
are fed to the dashboard.
In addition OCS feeds the dashboard with
crew rotation, indicating status on board

Quality of data in OCS is essential for

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.
All measured elements have defined standards.
Green = Function at or above benchmark
Yellow = Acceptable
Red = 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
Depending on importance,
deficient barrier elements may
render the entire barrier function
Aggregation into Area
Barrier functions may be
aggregated into Areas.
6 different areas have been
• Living Quarter
• Drilling area
• Open deck
• Pontoons and columns
• Machinery spaces
• Well Test Area
