Коммерческие водолазные работы в Германии: Регулирование и на что обратить внимание при выборе подрядчика
Germany operates one of the most stringent regulatory frameworks for commercial diving in Europe. For project owners, facility managers, and procurement teams commissioning underwater work, understanding the legal landscape is not optional — it directly affects liability, insurance validity, and the safety of everyone on site.
This guide breaks down the key regulations governing commercial diving in Germany and outlines what separates a compliant, capable contractor from one that puts your project — and your organisation — at risk.
The Regulatory Framework: DGUV Vorschrift 40
The foundation of commercial diving regulation in Germany is DGUV Vorschrift 40 “Taucherarbeiten” (Diver Operations), issued by the Deutsche Gesetzliche Unfallversicherung — Germany’s statutory accident insurance body. It is binding for any company that carries out or commissions diving work on German territory.
DGUV Vorschrift 40 sets minimum requirements across four areas:
Diver qualifications: All professional divers must hold recognised commercial diving certifications. A designated dive supervisor must be present on every operation.
Equipment standards: Surface-supplied diving systems, full-face masks or helmets, communication systems, and standby diver provisions are mandatory for most commercial operations. Scuba-only configurations are heavily restricted.
Medical fitness: Every diver must hold a valid G31 occupational health certificate — a specialist medical examination specifically for professional divers, renewable at defined intervals.
Documentation: A dive log must be maintained for every operation, alongside a site-specific risk assessment and a written emergency plan.
Importantly, DGUV Vorschrift 40 is complemented by DGUV Regel 103-005, the technical guidance document that replaced the former BGR 237. Together, these two instruments form the complete compliance baseline for commercial diving in Germany.
What This Means for You as a Client
Commissioning diving work does not transfer your responsibility to the contractor. German occupational health law — the Arbeitsschutzgesetz — places a co-responsibility on the client to verify that any contractor engaged meets the required standards. In the event of an incident, liability can extend to the commissioning party if due diligence was not carried out.
Before awarding any diving contract in Germany, you should request and review:
- Proof of diver qualifications for all personnel assigned to your project
- Valid G31 medical certificates for each diver
- Evidence of surface-supplied equipment conforming to DGUV standards
- A site-specific risk assessment prepared in advance
- A written emergency and rescue plan including the nearest hyperbaric chamber
- Commercial liability insurance covering diving operations
This is not bureaucratic box-ticking. These documents are your evidence of due diligence — and your protection if something goes wrong.
What to Look for in a Commercial Diving Contractor
Beyond baseline compliance, the quality of a commercial diving contractor varies significantly. Here is what distinguishes professional operations from those that simply meet the minimum threshold.
Transparent documentation from the outset A reliable contractor will provide compliance documentation before work begins, without being asked twice. If a company is hesitant to share diver qualifications, equipment inspection records, or insurance certificates, treat that as a serious warning sign.
Genuine risk assessment — not a template DGUV Vorschrift 40 requires a site-specific risk assessment for every operation. This means a qualified dive supervisor must assess your specific site conditions: water quality, visibility, current, confined space risks, proximity to operating plant, contamination potential. A generic document copied from a previous project does not meet the standard.
Industry-specific experience Commercial diving covers a wide range of environments — each with distinct hazards. A contractor experienced in port infrastructure inspections is operating in a fundamentally different risk environment than one working inside a chemical facility or a pressurised water utility structure. Sector-specific experience matters.
Standby diver provision Under DGUV Vorschrift 40, a standby diver — fully equipped and ready to enter the water — must be present during operations. This is not negotiable. Any contractor proposing to work without one is non-compliant.
Clear communication and project coordination Diving operations require coordination with your wider site: isolating inflows, halting adjacent plant operations, managing vessel traffic, briefing your own safety team. A professional contractor will manage this process proactively, not reactively.

The Bottom Line
Germany’s commercial diving regulations exist because the consequences of non-compliance are severe — for workers and for the organisations that commission their work. DGUV Vorschrift 40 is not guidance; it is law.
Choosing a contractor who operates to its full requirements protects your project, your liability position, and the people carrying out the work. TUF International operates in full accordance with DGUV Vorschrift 40 and DGUV Regel 103-005 across all sectors and project types.
