Installation Risk Analysis
Installation Risk Analysis (IRA) is normally performed prior to installation of a new facility or before revamping of an existing facility. The purpose is to identify major risks and to discuss risk reducing measures for implementation. The time schedule of an Installation Risk Analysis is typically from a couple of weeks to some months.
In many cases, both SIMOPS and Emergency Preparedness Analysis (EPA) will be a part of the Installation Risk Analysis (named TRA below). The diagram displays the connection between EPA, SIMOPS and IRA and reflects the scope for a major upgrade of a fixed offshore installation.
