Description

Introduction

Subsea Inspection, Maintenance, and Repair (IMR) is a critical aspect of offshore oil and gas operations. It ensures the integrity, safety, and optimal performance of subsea infrastructure throughout its lifecycle. IMR activities involve regular inspections, preventive maintenance, corrective repairs, and the use of specialized tools and technologies such as ROVs, diving systems, and autonomous vehicles. This course provides participants with knowledge of IMR strategies, operational procedures, and industry best practices to maintain subsea assets efficiently and safely.

Prerequisites

Participants should have:

1. Basic knowledge of subsea field development and equipment.

2. Understanding of offshore operations and subsea production systems.

3. Familiarity with ROVs, diving operations, or subsea intervention techniques.

4. Technical or engineering background in mechanical, petroleum, or subsea disciplines is advantageous.
