Subsea Well
Intervention Module

Purpose

The Subsea Module provides candidates with the specialist knowledge and operational understanding required to safely manage subsea well intervention pressure control activities.

This standalone discipline can be added to an existing IWCF Well Intervention Pressure Control Level 4 certificate, allowing candidates to extend their certification to include Subsea Operations.

The module focuses on subsea well control architecture, systems, barrier management, and the operational challenges unique to deepwater and subsea intervention environments.

What the Course Covers

The module follows the IWCF syllabus for Subsea Operations and is delivered in accordance with the official ATT course outline, across four core areas:

Subsea Intervention Fundamentals

Subsea Intervention Lubricator (SIL)

Open Water Intervention Riser Systems (OWIRS)

Through-BOP Riser Systems (TBRIS)

Training Format

• Pre-course learning materials and training manual available upon registration
• 1 day of interactive classroom-based instruction (Thursday, 0830–1700)
• Daily LMS revision session (45 minutes)
• IWCF assessment conducted on Friday morning, 08:30–09:30

Prerequisites

• Candidates must be pre-registered with IWCF and provide a valid 6-digit IWCF Candidate Registration (CR) Number.
• Candidates must hold a valid IWCF Level 4 Well Intervention Pressure Control Certificate. On successful completion, Subsea will be added to this.

Who It Is For

This course is recommended for individuals with supervisory responsibility for pressure control during subsea completions and intervention operations, including:

• Subsea completions / workover / intervention supervisors
