CORAM AND WSE
In order to satisfy PSSR or the Offshore Safety Case requirement, an operator must demonstrate that operating systems are safe and major accident risks are as low as reasonably possible. Risk assessments are routinely used to satisfy these requirements.
CAPCIS have developed an in-house Corrosion Risk Assessment
Methodology (Coram) based on industry standards and
following the guidelines contained within the HSE Corrosion
Management Guidelines. The method assesses a number
of common degradation mechanisms and has the flexibility
to incorporate additional mechanisms as required. A
semi-automated assessment can be carried out in Excel
or in MS Access, on corrosion circuits and vessels.
The flexibility of the system enables it to be integrated
into existing Management Systems and linked to failure
and anomaly databases as appropriate.
The Coram System can be used to drive the development of Written Schemes of
Examination (WSE) for process plant. The development
of the WSE is semi-automated and enables inspection
techniques and inspection locations to be defined based
on inspection data and corrosion risks for individual
vessels and corrosion circuits. Regular synchronisation
between the Coram and the WSE engines ensure that the
most upto date information is used to generate the inspection
plans.
The use of the Coram and WSE system, avoids the need for labour intensive inspection/integrity management systems. The system is MS Access based and therefore avoids additional IT requirements. A competent engineer can drive the engine with little training and data gaps can be managed by engineer judgement.
