RAM Analysis is an established analytical methodology used to predict the failures. It is done by assessing failure modes, frequencies, and consequences to estimate the production availability of any system
Functional analysis would be done to identify the equipment constituting the overall system along with functional relationship between each of the equipment. This is followed by FMEA to identify the events which may cause production losses, their consequence on the production availabilities, as well as, the quantification of the parameters to be used for subsequent availability calculations. The overall idea is to find out if the estimated production availability meets the requirements, and to identify the most cost-effective and reliable parameters to find an optimum solution in terms of profit
iFluids Engineering has a wealth of expertise in performing Reliability, Availability and Maintainability (RAM) analyses for the oil and gas industry – from subsea, topside and onshore facilities.
Our RBI services would enable you to have the right approach to your inspection and maintenance planning. RBI is a methodology which used risk as a key factor to manage the inspection activities. Risk Based Inspection (RBI) is done by calculating both the consequences of possible failures and the likelihood of those failures. This combination would help in identifying the equipment’s which would need the most attention for managing risk .
The technical standard IEC 61511 sets out a good practice for engineering of safety instrumented systems that ensure the safety of process industries. This standard defines the functional safety requirements established by IEC 61508 in process industry sector terminology. It also focuses attention on one type of instrumented safety system used within the process sector, the safety instrumented system (SIS).
IEC 61511 covers the design and management requirements for SISs. Its scope includes initial concept, design, implementation, operation, and maintenance through decommissioning. The standard starts in the earliest phase of a project and continues through start up. It contains sections that cover modifications that come along later, along with maintenance activities and the eventual decommissioning activities.
The SIL review session would be a guided team brainstorming activity that benefits from a structured method and from the broad experience of a multidisciplinary team led by a SIL facilitator. The methodology that will be employed for the SIL determination uses Layer of Protection Analysis (LOPA) technique.
Safety Integrity Level (SIL) CLASSIFICATION
The SIL Classification would be carried out to assign the Safety Integrity Level (SIL) for each SIF. The Layer of Protection (LOPA) methodology would be adopted for more quantitative analysis. The LOPA methodology use orders of magnitude categories for initiating event frequency, consequence severity, and the likelihood of failure of IPLs to approximate the risk of scenario.
