COMMERCIAL & OCCUPATIONAL DIVING
Your management systems describe and audit how work should happen. We address how it actually does.
Commercial diving operates inside some of the most comprehensive safety frameworks in any industry. Risk registers, permit-to-work systems, diving supervisors, medical fitness standards. And yet serious incidents keep occurring. Not because the systems failed, but because the humans operating within them did what humans do. We bridge that gap.
"The course made me aware of different forms of communication and highlighted the need to work as a team. It highlighted that human error is part of who we are but there is ways in which we can reduce it. It taught me how to risk manage, but introduced a fun and exciting way to do it. Others should do this course as it will highlight different techniques to learn about human factors and how they can be used within our company from the top of the tree level down to the base level, and that it can create a common goal for all people involved within the company." - AB, Diving Supervisor
The procedures are necessary. They're also not sufficient
The majority of serious incidents in commercial and occupational diving do not result from procedural absence. They result from normalisation of deviance/risk; the gradual drift away from standards that happens in every operational environment, at every level of seniority, when nothing has gone wrong. Yet.
They result from supervisors who feel pressure to proceed. From divers who see something wrong and don't say it. From teams that have lost the habit of genuine pre-dive briefing. From incident investigations that stop at the individual and never reach the system.
None of those are addressed by adding another layer of procedure. They require a different understanding of how human performance works, and a culture in which that understanding is applied, not just documented.
~80%
of serious incidents in commercial diving involve human and organisational factors, not technical failure. The technical investigation is necessary. It is rarely sufficient.
Work-as-Done
The gap between how procedures say work should be done and how it is actually performed is present in every operation. The question is whether it is visible, understood, and managed, or remains invisible until it becomes an incident.
THE GAPS
What conventional safety training doesn't cover.
Industry-standard commercial diving safety training covers procedures, hazard identification, emergency response, and equipment. It does not typically address the following; which is where most incidents originate.
Normalisation of deviance/risk
How operational drift accumulates over time, why it is invisible to those inside it, and what structural practices interrupt it before it becomes an incident.
Stop-work authority
Why divers and supervisors often don't use it when they should, and what organisational and team conditions make it genuinely available rather than theoretically available.
Supervisor decision-making
How commercial diving supervisors make go/no-go calls under time, commercial, and organisational pressure, and what cognitive and team factors compromise those decisions.
Incident investigation quality
Most investigations in commercial diving identify the proximate human error and stop there. The systemic conditions that produced the error, and that will produce the next one, remain unaddressed.
Power distance
The hierarchical structures of commercial diving operations create pressure gradients that suppress concern-raising. This is predictable, measurable, and manageable, if it is recognised.
Learning culture
The conditions required for near-miss reporting, honest post-job debriefs, and genuine learning from experience, rather than documentation-focused DEBrIEFs and after-action reviews.
WHAT WE DO
Our approach for commercial and occupational operators.
DCRM training for commercial diving contexts is adapted from the core HFiD curriculum with case studies, language, and scenarios drawn from commercial and occupational operations. The conceptual framework is the same. The application is specific.
01
Work-as-Done vs Work-as-Imagined
We surface the gap between your documented procedures and the way work actually gets done, without blame, and with a view to making the gap smaller. This is the foundation of all the other work.
02
Supervisor and team non-technical skills
Situation awareness, communication under pressure, decision-making in ambiguous conditions, workload management, and team leadership, applied directly to commercial diving contexts.
03
Just Culture implementation
What a Just Culture actually requires, not the policy statement, but the organisational conditions: leadership behaviours, and investigation practices that make it real rather than aspirational.
04
Incident analysis and learning
How to investigate your own incidents and near-misses in a way that produces systemic understanding, using LFEO/LEODSI and similar tools, rather than a narrative that stops at the individual who was closest to the event.
05
Leadership and safety culture
How senior leaders and supervisors shape the conditions in which their teams operate, the culture that determines whether concerns are raised, whether near-misses are reported, and whether learning actually occurs.
"As a governance specialist for commercial diving activities, the course reinforced my beliefs in the value of a human performance orientated approach to safety, where greater emphasis on the person is key to making further gains. Fundamental in all of this is the need to understand how to get the best from yourself and others. The Human Diver gives you the tools to better understand the why and how behind the human factors that directly impact on outcomes; it is a hugely valuable training package applicable to anyone who is engaged in risk to life activities.

HOW WE DELIVER
Flexible delivery for operational teams.
We work with commercial diving contractors, vessel operators, and project managers to deliver training that fits the operational reality, not the other way around.
DCRM: Essentials (Online)
Self-paced online pre-learning covering the conceptual foundations; human error, situation awareness, communication, decision-making, Just Culture. Suitable for all team members prior to face-to-face sessions. Goes live 1 May 2026.
DCRM: Applied Skills (On-site)
Two-day face-to-face immersive programme. Can be delivered on-site at your operational base, vessel, or training facility. Includes scenario work, debrief practice, and application to your specific operational context. Available now. Get in touch.
Bespoke programmes
For operators with specific incident histories, regulatory requirements, or operational cultures, we develop tailored programmes that address your context directly. Contact us to discuss scope, format, and delivery.
Supervisor & management sessions
Focused sessions for diving supervisors and operations managers on decision-making under pressure, safety culture leadership, the organisational conditions that either support or undermine stop-work authority, plus learning from emergent outcomes when things don't necessarily go to plan.
Join the Waitlist
Essentials will be live on 1 May 2026.
