Guidance on Contractor Management

Shutdowns, outages and turnarounds (SOTs) of major accident hazard (MAH) sites are challenging. The SOT requires a lot of disparate repair and upgrade work to be done in a short period of time. Operators typically do not carry the staff or other resources to do this, but plan the work and engage one or more specialist contractors to carry it out. Often this involves the employment of a large number of contractor staff for relatively short periods of time. The contractors may be unfamiliar with the site and often will be undertaking non-routine tasks. A number of significant issues have causes or solutions related to human factors (HF).
