This document discusses performance standards for offshore plant safety design. It defines performance standards and lists factors to consider like functionality, availability, reliability, survivability, dependency and compatibility. It describes developing standards for control measures and integrating maintenance software. It also addresses assurance of control measures through validation, compliance monitoring, and contingency planning for failures. Key terms like major accident hazards, safety critical elements, and critical operating parameters are defined.

Definition of Performance Standard
• Definition
The performance standards, by definition, are associated with
controls used as a basis for managing the risk of an MAE. The
performance standards are the parameters against which MAE
controls are assessed to ensure they reduce risks to ALARP.
They facilitate the transition from the theoretical to the
practical in the MAE risk management process.
• In developing these standards for a facility the operator
should consider what level of performance it is reasonable to
achieve from each control measure, considering:
1. Functionality
2. Availability
3. Reliability
4. Survivability
5. Dependency
6. Compatibility
• Performance standards enable the operator to measure, monitor and test
the effectiveness of each control measure and take corrective action
based on deviations or trends.

• Content?
The following sections explore aspects of control measures which operators may
choose to measure and set standards for, bearing in mind that these may not all
apply to all control measures
1. Functionality
The functional performance of a control measure is what it is required to do.
To establish COP(critical operating parameter) document is important.
Ex) The performance standard for a firewater system would specify the
quantity of fire fighting water, the delivery rate and the response time.
2. Availability
The availability of a control measure is the probability that the control has not failed or
is undergoing a maintenance or repair function when it needs to be used.
Ex) The battery life on an emergency lighting system should be equal to, or more than,
the intended length of time the lights would be used.
3. Reliability
The reliability of a control measure is the probability that at any point in time it will
operate correctly for a further specified length of time.
It is measured by the mean time between failure (MTBF)
Ex) Suppose maintenance becomes proficient at repairing a recurrent failure, reducing
downtime. Availability will improve but reliability will not be improved.

4. Survivability( 생존 가능성 )
-Whether control measure is able to survive a potentially damaging event such as
fire or explosion
EX) Survivability performance should be considered for blow-down &
Emergency Shut Down systems, fire protection systems, emergency escape
systems.
5. Dependency( 의존성 )
-Degree of reliance on other systems in order to be able to perform its intended
function
-If several control measures can be disabled by one failure mechanism, or the
failure of one control measure is likely to cause the failure of others, The
control measures are not independent.
Ex) Accommodation module Temporary Refuge : In the event of an uncontrolled
gas release, the integrity of the temporary refuge is supported and protected by
a number of features including HVAC(heating, ventilation, air conditioning) shutdown
6. Compatibility( 호환성 )
-Whether alternative control measures may interact with other controls and the
rest of the facility.
-Whether new control measures are compatible with the facility and any other
control measures already in use.

Integrating CMMS and ERP
CMMS : Computerized Maintenance Management Software
ERP : Enterprise Resource Planning
•CMMS and ERP Integration allows you seamlessly to tie your purchasing,
accounting, inventory, and other pertinent ERP data directly with your
maintenance operations – combining the ease-of-use and robust
functionality with the data resources of your ERP.
•Integration provides a basis for the process- and practice-oriented
introduction of CMMS. Benefits are :
1. Avoidance of investment without expected result. ---- Expected
investment can be viable
2. Better return on CMMS investments already made
3. Shorter system introduction and ramp-up time
4. Support for achieving maintenance goals and strategy as well as the
continual improvement process
•In practice, an efficient CMMS solution:
1. Increases plant availability and personnel productivity
2. Lowers maintenance costs
3. Reduces capital commitment through more-effective material
management

Assurance of Control Measures
• Sustaining Technical Integrity of Control Measures .
 The operator must demonstrate
that the control measures
identified are, and will continue
to be adequate for their intended
purpose.
 So, there must be a clear link
between performance standards and
operator’s safety management
system.
• Monitoring Compliance with Performance Standards
SMS controls should be subject to monitoring, audit and review.
 Contingency Measures for Control Measure Failure
As part of the development of performance standards for SCE, the operator
should consider the possible failure modes and develop associated
contingency measures to apply if a performance measure is not met.

Assurance – Validation & Ongoing Assurance
Validation 이란 ?
•Validation is an assurance activity that may be requested by NOPSEMA as per OPGGS(S)
2.40.
•The validation process is therefore the first assurance activity in the lifecycle
management of control measures. For new safety cases and for revised safety cases
where the operator proposes to modify or decommission the facility, the operator must
not submit the safety case or revised safety case before the operator and NOPSEMA have
agreed on the scope of validation ---- All scope of validation must be carried out
after the operator agree
Ongoing Assurance
•The OPGGS(S) Regulations also include a requirement for the safety case to describe the
means by which the operator will ensure the ongoing adequacy of the design, construction,
maintenance and modification of the facility. This obligation on the operator is detailed in
OPGGS(S) 2.12.
•There is no prescribed methodology for demonstrating the adequacy of control measures,
however there are several basic approaches which may be used to support an operator's
provision of evidence and justification within the safety case. Operators could
consider using one or more of these approaches, but should also be prepared to
consider developing specific approaches appropriate to their facilities.
•(Approaches - Comparison with Codes and Standards, Audit against good practice,
Technical Analysis, Performance Data Improvement Approach, Benchmarking and Judgement
Approach, Practical Tests.)

• SCE & MAH
- 해양플랜트 설계 과정의 위험도 분석 (Risk Analysis) 은 주요사고 위험요인 (MAH :
Major Accident Hazard) 과 안전 취약 요소 (SCE : Safety Critical element) 에 대해 수행

석 (Production availability) 등이 포함된다 .
• COP
- 운전 주요 지표 (COP : Critical Operating Parameter) 는 운영자가 공정을 잘 운영하거
나 , 관리하는데 높은 의존도를 띄는 지표로 정의된다 .
