Stepping Below the Surface: CSWIP 3.4U Inspection 1/3
In the world of offshore operations, there’s a realm that demands precision, resilience, and technical insight—the underwater environment. If you're already a diver, ROV operator, or involved in subsea engineering, you likely know how critical inspection work is to offshore asset integrity. But overseeing that work takes a whole new level of expertise.
This is not a surface-level certification. It’s a strategic credential that formally recognises your ability to plan, manage, and interpret underwater inspection campaigns. If you're looking to transition from executing inspections to overseeing them, this course gives you the credibility and capability to take charge.
The CSWIP 3.4U course provides advanced knowledge of underwater non-destructive testing (NDT), data interpretation, quality assurance, and inspection planning, geared specifically for the subsea environment. It's a robust path to professional growth—technical, focused, and industry-aligned.
You complete the theory online at your convenience, with only the final exam taking place at a TWI Training Centre.
Who’s This For?
This course isn’t for entry-level candidates. It's tailored for experienced professionals—those who've logged time underwater, worked with ROVs, handled NDT tools, or have a background in subsea engineering. Whether you're a certified underwater inspector or an ROV veteran with experience, this course aligns with your trajectory.
If you're already within the CSWIP system—perhaps certified as a 3.1U, 3.2U or 3.3U—you’ll find the 3.4U to be the logical progression that shifts you from application to coordination.
Career Clarity with Deep Roots
Unlike short technical courses, this one’s not a skill tick-box. It’s career architecture. With the 3.4U certification, you’re not just 'trained'—you’re certified to lead. Inspection controllers are the bridge between contractors and clients i.e. diving, ROV, NDT and field operators and asset owners etc respectively. CSWIP 3.4U holders cover the entire span of subsea inspection projects, from designing the initial scope of work through to the delivery of a final project report to clients.
The course is split into two parts: theory and exam. You complete the core learning modules remotely—in your time, on your terms. No need to step away from work or travel until exam day. When it’s time to prove your skillset, you’ll attend your chosen TWI location for the assessment.
Depending on where you sit your exam, you’ll go through a seamless 12-day schedule, wrapped around the exam requirement. The flexibility makes this course ideal for active professionals. It respects your schedule while delivering the technical depth needed to elevate your career.
