Where we work

Built around
the environment.

Specialist assurance shaped by the operational setting—not imposed from outside it.

Sector 01

Commercial diving

Assurance that understands the dive spread, the people and the operation.

CDAS provides independent assurance across inland/inshore, offshore and defence-aligned diving. Our work examines the complete system—planning, supervision, competence, equipment, emergency preparedness and what is actually happening at the worksite.

  • Contractor capability and project audits
  • Diving Technical Authority support
  • Client representation
  • Diving systems, plans and risk assessments

Sector 02

Defence & government

Discreet technical confidence in highly governed environments.

CDAS supports defence-aligned organisations and public-sector estates where operational delivery must meet demanding governance, assurance and stakeholder requirements. We translate diving and marine risk into clear, defensible decisions for the client organisation.

  • Independent technical governance
  • Supplier and contractor assurance
  • Operational readiness and mobilisation review
  • Defensible advice for duty holders and stakeholders

Sector 03

Marine & offshore

Independent eyes where interfaces, logistics and consequence meet.

From vessel-side operations to remote mobilisations, CDAS provides experienced oversight that keeps the client connected to the reality of delivery. We focus on readiness, interfaces, change and the controls that protect people and the operation.

  • Client representation and operational oversight
  • Pre-mobilisation and equipment assurance
  • Marine interface and emergency planning
  • Incident review and operational learning

Sector 04

Infrastructure

Specialist assurance for diving embedded within complex facilities and projects.

Diving risk is often only one part of a larger infrastructure system. CDAS helps clients control the interfaces between the diving contractor, asset, site rules, isolations, water systems, temporary works and wider project delivery.

  • Inland/inshore diving assurance
  • Isolation and differential-pressure control
  • Asset inspection and maintenance scopes
  • Contractor, facility and stakeholder interfaces

Where sectors meet

The hardest risks rarely stay
inside one box.

CDAS is particularly effective at the interfaces: defence and commercial delivery, marine and infrastructure, documented governance and operational reality.

Your environment. Our independent judgement.

Bring us the operation.
We will find the clarity.

If your requirement crosses several sectors or does not fit a standard category, that is often where independent assurance adds the greatest value.
