Commercial & DefenceWhat we do
CDAS provides independent technical assurance across commercial diving, defence, marine and infrastructure—bringing senior judgement directly to the point where risk, regulation and delivery meet.
Every engagement is shaped around the operation and the outcome. No generic package. No theatre. No unnecessary complication.
Independent technical governance for organisations that need competent diving oversight without building the entire capability in-house.
Available as retained support or against a defined scope.
Evidence-led assessment of diving contractors, systems and operations against UK legal duties, approved codes of practice and recognised industry guidance.
Clear findings, proportionate grading and practical routes to closure.
Independent, experienced representation at the point of delivery—protecting the client’s interests while supporting safe and effective operations.
Senior operational judgement where the work is actually happening.
Structured investigation of complex or high-consequence events, combining technical evidence, human factors and operational reality.
Focused on learning, defensibility and prevention—not blame.
Development and review of the documents that control diving work, written to be technically robust and usable by the people delivering it.
Closing the gap between documented control and real-world performance.
Independent auditing and improvement support for quality and occupational health-and-safety systems in technical, marine and high-risk environments.
Systems assessed in context—not reduced to clause checking.
Bespoke technical training built around the task, the learner and the competence the organisation actually needs to demonstrate.
Complete, deliverable training packages—not presentation slides alone.
Independent review of diving equipment spreads, launch-and-recovery arrangements and hyperbaric capability against the intended operation.
Assurance based on suitability, traceability and operational readiness.
