Section C: ALE - Planning and Implementing
(Questions for offshore OIM, core crew, control room operators, production
operators, maintenance technicians, Independent Competent Persons, and
safety reps)
Principal Questions:
1) What do you consider the ageing and life extension issues to be for
process safety?
2) Can you give some examples where you have encountered issues
regarding ageing and life extension?
3) How did you deal with these?
4) Describe how it is ensured that:
a) the design basis for topsides plant and equipment is suitable for
current and projected production profiles, and fluid composition;
b) modifications to the process system are integrated with the existing
production operations;
c) performance standards for safety critical elements on existing (as
well as new) process systems are suitable and sufficient for the
revised functional specification;
d) improvements in health, safety, and welfare standards are
implemented where reasonably practicable in compliance with
current HSE and Industry guidance, and applicable national and
international standards and codes of practice;
e) the mechanical integrity of systems containing hazardous materials
is sound;
f) obsolescence of software and hardware systems for control and
instrumentation for existing systems are identified, and alternatives
sourced;
g) redundant equipment that represents significant congestion and
aggravated explosion damage, or barrier to emergency response are
removed where this is reasonably practicable;
h) failure of one or more prevention or mitigation measures does not
increase risk to the most exposed group of workers to intolerable
levels for continued production operations
How does age trigger the above processes
How is safety culture on ALE encouraged?
How are views on ALE communicated to and from the workforce
How do you assure the competency of personnel involved in the
management, operation, inspection, and maintenance of plant and
equipment?
9) How is competence assured for contractors?
10) How do you document Operational Controls and Maintenance Records

Section D: ALE - Measuring Performance
(Questions for offshore OIM, core crew, control room operators, production
operators, maintenance technicians, Independent Competent Persons, and
safety reps)
Principal Questions:
1)
2)
3)
4)
5)
What parameters are measured during operation/inspection?
Where are the performance standards recorded?
How do you track progress for testing/inspection?
What are your key leading and lagging performance indicators?
How are these communicated to senior management?
Benchmarks sought in replies:

Benchmarking of design against current standards

Inspection methods and techniques are used to detect ageing i.e.
creep, cracking, corrosion, damage, and wear

More detailed inspection required if life extension is contemplated
or deterioration from ageing is detected

Register of weeps, leaks, and breaks i.e. minor, significant and
major hydrocarbon releases to inform the life extension analysis

Data measurement which does not meet the performance
standards used to determine remaining or extension to life

Formal life-extension studies are performed

