SDR — Shutdown Readiness Review

A structured review confirming that all preparations required for a planned shutdown or turnaround have been completed before execution begins.

Definition

A Shutdown Readiness Review (SDR) is a structured review conducted before a planned shutdown, turnaround or major maintenance event to verify that planning, resources, procedures, materials, safety controls and logistical arrangements are in place for safe and efficient execution. The review confirms organizational readiness before shutdown activities commence.

Why It Matters

Shutdown Readiness Reviews verify that organizations are fully prepared to execute planned shutdowns and turnarounds safely and efficiently.

In Practice

Shutdown Readiness Reviews are commonly performed before major maintenance events and turnarounds to verify work scope, resource availability, safety preparations, contingency plans and operational readiness.

Common Misuse

A Shutdown Readiness Review confirms readiness to safely execute a planned shutdown or turnaround, whereas a Pre-Startup Safety Review verifies readiness to safely restart the facility following construction, modification or maintenance.
