Imagine the scenario. You have mobilised the vessel. The dive team is briefed. The client is onsite. But during the pre-dive audit, the surveyor finds a single expired vial of adrenaline or an incompatible airway tube in the medical chest. Operations halt. The vessel sits idle. Thousands of pounds bleed from the budget every hour while you scramble to fly in a replacement.
This is not a hypothetical nightmare. It is a common reality for projects that treat medical kits as an afterthought.
In the offshore industry, the DMAC 015 (Medical Equipment on Dive Sites) standard is the global benchmark for safety. It is not just a suggested list. It is a rigorous requirement enforced by IMCA, OGP clients, and national regulators. Compliance is not about simply buying a box of bandages. It requires understanding the specific medical risks of your operation and ensuring your Life Support Technicians (LSTs) and Diver Medic Technicians (DMTs) have the tools they need to save a life under pressure.
Here is your guide to navigating DMAC 015 requirements and keeping your dive spread audit-ready.
Decoding DMAC 015: Which Kit Do You Actually Need?
The first mistake many procurement officers make is assuming one kit fits all. DMAC 015 distinguishes between different levels of diving operations. You must match the kit to the scope of work.
The Surface Supply Kit (Air / Nitrox)
This kit is designed for diving operations where the diver is not under saturation. This covers most civil engineering, inshore, and air-range offshore projects. The priority here is immediate stabilisation. The diver can be brought to the surface quickly, so the kit focuses on:
- Trauma care: Dealing with crush injuries, severe cuts, or amputations.
- Resuscitation: Managing cardiac arrest or drowning immediately on deck.
- Decompression Illness (DCI): Basic drugs and fluids to support the diver in the chamber while receiving therapeutic recompression.
The Saturation / Bell Kit
When divers are living in saturation, they are days away from a hospital. The medical kit inside the chamber (and the bell) effectively becomes a remote emergency room. This kit includes everything in the surface supply kit but adds:
- Long-term care supplies: Catheters, advanced nursing hygiene supplies, and stronger antibiotics.
- Pressure-safe diagnostics: Equipment that functions correctly in a helium atmosphere.
- Bell Survival Packs: Specialised compact kits kept inside the diving bell for immediate emergencies at depth.
The Hyperbaric Rescue Unit (HRU) Kit
This is your lifeboat scenario. If the vessel is in distress and the saturation system must be evacuated, the HRU kit goes with the divers. It is stripped down to survival essentials: pain relief, basic fluids, and thermal protection.
Inside the Case: Critical Categories & Common Oversights
You do not need to memorise every line item in the DMAC guidance document. However, you must ensure your kit covers these four critical categories.
1. Airway Management
If a diver cannot breathe, nothing else matters. Old kits often relied on complex intubation tools that are difficult to use in a cramped chamber. Modern DMAC 015 compliant kits often prioritise supraglottic airways like i-gels or Laryngeal Mask Airways (LMAs). These are easier to insert quickly and create a secure seal for oxygen delivery.
2. Trauma & Bleeding Control
Offshore decks are hazardous environments. Your kit must contain military-grade tourniquets (like the CAT or SOFTT-W) and haemostatic dressings (such as Celox or QuikClot). These chemically treated gauzes stop heavy arterial bleeding in seconds. Standard cotton bandages are not enough for severe trauma.
3. Diagnostics Under Pressure
This is a frequent audit failure point. Standard medical gear often fails in hyperbaric conditions.
- Mercury thermometers are banned due to toxicity risks.
- Glass thermometers can shatter.
- Standard BP cuffs may give false readings if the gauge is not vented for ambient pressure. Your kit must contain aneroid sphygmomanometers and digital thermometers certified for hyperbaric use.
4. Drugs & Fluids
The drug inventory is split into two sections.
- DMT Access: Pain relief and basic medications the Diver Medic Technician can administer under standing orders.
- Doctor Only: Controlled drugs (like strong opioids) and IV medications that can only be given under direct instruction from a topside specialised diving doctor via telemedicine.
The “Expiry Date” Headache: Managing Perishable Stock
The biggest threat to your compliance is not missing equipment. It is expiry dates.
A medical kit contains hundreds of items with different shelf lives. Saline fluids might last two years. Eye wash might last six months. Adrenaline degrades quickly if exposed to light.
If an auditor finds a single expired item, they can technically fail the entire spread.
Best Practice: Do not rely on a manual check the day before mobilisation. Use a digital tracking system or a simple spreadsheet that flags items three months before they expire. This allows you to order replenishment packs well in advance. At iSubC, we recommend replacing consumables in “modules” rather than individually to ensure consistent expiry dates across the kit.
Training & Competency: The Human Factor
Buying the best DMAC 015 kit on the market is useless if your team does not know how to open it.
The Diver Medic Technician (DMT) is the primary user of this equipment. However, in an emergency, adrenaline runs high. The kit layout must be intuitive. We strongly recommend running Medical Drills as part of your regular safety meetings.
- Can the DMT locate the laryngoscope in under 30 seconds?
- Is the oxygen cylinder full and the regulator compatible?
- Are the seals on the hard case intact?
Furthermore, DMAC 015 requires that you have established communication with a diving medical specialist. Your kit should include a laminated “Comms Card” with the emergency numbers for onshore medical support.
How iSubC Ensures Audit-Ready Compliance
Safety is our business. We understand that for a Dive Superintendent, the medical kit is just one of a thousand items on the manifest. We make it easy to get it right.
iSubC supplies fully stocked, DMAC 015 compliant medical kits housed in rugged, waterproof Peli cases. We do not just ship the box. We provide:
- Full Inventory Checklists: Organised by category for easy auditing.
- Certificates of Conformity: Proof that every item meets regulatory standards.
Whether you need a compact Surface Supply kit for a civil job or a full Saturation setup for the North Sea, we ensure your medical capability meets the highest industry standards.
Conclusion
A medical kit is the only piece of equipment you buy hoping to never use. But when an accident happens, it becomes the most valuable asset on the vessel. Compliance with DMAC 015 is not just about passing an audit. It is about fulfilling your duty of care to the men and women working underwater.
