The 10th MED regulation and survey vessel equipment approvals

What changed on 30 June 2026

On 30 June 2026 the European Commission adopted the 10th Implementing Regulation, (EU) 2026/1434, amending the Marine Equipment Directive 2014/90/EU. The text was published in the Official Journal, enters into force on 31 August 2026, and repeals the 9th Implementing Regulation (EU) 2025/1533. It names four groups directly: manufacturers, designers, yards, and owners of EU-flagged vessels.

Two facts frame everything that follows. No new MED equipment items were added. And the certification basis for a long list of existing items has moved – updated carriage, performance and testing requirements, marked in the annex as “(NEW ROW)”. The affected items span rescue boats (MED/1.43), tanker flame-passage devices (MED/3.12a–d), portable gas detection for explosive atmospheres (MED/3.30b), fixed water-based local fire-fighting for category A machinery spaces (MED/3.48), a block of bridge navigation equipment (propeller revolution indicator MED/4.21, track control MED/4.33, gyro compass MED/4.65), and most of the GMDSS radio suite (MED/5.1 through MED/5.22).

The transition rule is specific. Marine equipment already compliant with a member state’s national type-approval requirements in force before 23 September 2025 may continue to be placed on the market and installed on EU ships until 23 September 2028. From 31 August 2026, manufacturers must ensure products meet the updated regulation. Any Declaration of Conformity issued after that date must reference the 10th Implementing Regulation, and DNV, acting as a notified body, has signalled that some products will need new or additional testing before it can issue updated MED certificates.

Updated standards, not new hardware – and why that distinction bites

The MED works by pairing each listed item with a carriage requirement drawn from SOLAS, COLREG or the relevant IMO instrument, and with one or more international testing standards – IEC, ISO, ITU-R or an IMO resolution. The “wheelmark” on a piece of equipment certifies that a notified body has verified conformity to that pairing through the module route the manufacturer chose: EC type-examination (Module B) backed by a production-phase module (D, E or F), or unit verification (Module G).

When an implementing regulation updates a row, it is usually the referenced testing or performance standard that has moved to a new edition. That is not cosmetic. A type-examination certificate issued against a superseded edition may no longer support a fresh Declaration of Conformity. The box on the shelf has not changed, but the paperwork that lets it be placed on the market lawfully has. This is precisely why DNV’s notice separates two populations: products that simply need a DoC re-issued to cite (EU) 2026/1434, and products that need new or additional testing before an updated certificate can be issued at all.

In our experience, the practical consequence for a survey or geomatics function is that we should never treat “MED-approved” as a permanent attribute of a unit. It is a statement about a specific certificate, a specific standard edition, and a specific implementing regulation in force on the day the DoC was signed.

Where the changes touch a survey vessel

None of the updated items is a survey sensor. There is no multibeam, no INS, no USBL, no GNSS receiver in the MED annex – those sit outside the directive and are governed by class, by IHO S-44 for hydrographic performance, and by the vessel’s own survey acceptance criteria. What the 10th Implementing Regulation touches is the statutory equipment every survey vessel carries because it is a ship first. Three clusters matter.

Bridge navigation. The gyro compass (MED/4.65), track control system (MED/4.33) and propeller revolution indicator (MED/4.21) all sit on the updated list. The statutory gyro is not usually the primary heading source for the survey spread – that role belongs to an INS or a dual-antenna GNSS-aided heading device dimensioned to hold the positioning-uncertainty budget behind IHO S-44. But the statutory gyro remains a heading input to the DP system, a fallback reference, and an independent cross-check against the survey heading. When a gyro is replaced because its approval basis has moved, the survey team should re-verify heading offsets and the cross-check chain before the next mobilisation, rather than discover a lever-arm or C-O discrepancy on the first line.

GMDSS radio suite. The bulk of the NEW ROW list sits in Annex 5: VHF, MF and HF DSC radios, the DSC watch receivers, NAVTEX (MED/5.3), EGC (MED/5.4), HF MSI (MED/5.5), the 406 MHz EPIRB (MED/5.6), and the Inmarsat-C SES (MED/5.13). This is the equipment a flag or class radio survey examines. The approval basis and the installed-performance survey are separate matters, but a mismatch between a delivered DoC and the implementing regulation in force is the kind of documentation gap that surfaces during an audit and holds a certificate.

Life-saving and fire safety. Rigid-inflated rescue boats (MED/1.43), fixed water-based local application fire-fighting for category A machinery spaces (MED/3.48), and portable gas detection for explosive atmospheres (MED/3.30b) are on the list. The portable gas detection item is the one most survey and construction crews handle directly, because confined-space entry into tanks, cofferdams and void spaces depends on it. The tanker flame-passage devices (MED/3.12a–d) will not appear on most survey vessels, but they matter to any operator running converted tonnage that retains cargo systems.

The transition traps most crews miss

The 2028 date is not a general deadline. The 23 September 2028 sunset applies to a specific population: items newly listed under the 9th Implementing Regulation and held under a member state’s national type-approval that pre-dates 23 September 2025. Reading it as a blanket “everything must be re-certified by 2028” is wrong and will drive wasted refit spend. Reading it as “nothing changes until 2028” is equally wrong, because the DoC obligation bites on 31 August 2026.

Open purchase orders straddle the date. A radio suite or gyro ordered against a specification that cites the 9th Implementing Regulation, but delivered with a DoC signed after 31 August 2026, must reference the 10th. If the vendor’s Module B certificate has not caught up with the updated standard, the DoC cannot be issued cleanly and the delivery slips. Newbuild and major-refit programmes with equipment lead times spanning the date carry the obvious exposure.

Spares in the store have a vintage. A spare gyro, VHF/DSC set or EPIRB held as a rotable carries a DoC tied to the regulation in force when it was placed on the market. Equipment already lawfully installed is generally not disturbed by an update. But pulling a long-held spare from stores and fitting it after the transition can leave you installing equipment whose certification basis you cannot cleanly demonstrate at the next survey. Stock rotation for NEW ROW items deserves a deliberate look.

Flag matters. The directive binds EU-flagged vessels. A large share of the survey fleet flies non-EU flags, where MED equipment is common because it is the market default and eases reflagging, not because the directive compels it. Before launching a fleet-wide re-certification exercise, confirm which hulls are actually in scope. For chartered EU-flagged tonnage the obligation sits with the owner, but the exposure – a delayed mobilisation – lands on the charterer.

What to put in motion before 31 August 2026

• Build or update a wheelmark register. Map every MED item on each hull to its item number, notified-body certificate, and the implementing regulation its current DoC cites. Flag every entry on the NEW ROW list. Without this you are guessing at your exposure.
• Query open orders now. For any newbuild, retrofit or spares order with delivery after 31 August 2026, get written confirmation from the vendor that the delivered DoC will cite (EU) 2026/1434 and that the underlying type-examination certificate covers the updated standard – or a dated plan for the re-assessment.
• Engage the notified body early. DNV has flagged that some items need new or additional testing before updated certificates can issue. Testing and assessment lead times do not compress to fit a refit window. If a gyro or a radio needs re-qualification, get it on the programme rather than discover it at survey.
• Rotate NEW ROW spares deliberately. Check the DoC vintage of statutory spares you expect to install after the transition, and plan replacements so you never fit a certificate you cannot support.
• Fix the decision rights. Statutory equipment compliance normally sits with the marine or technical superintendent, not the survey or geomatics manager. That split is workable, but the interface has to be explicit: the survey function needs early warning when a statutory-equipment delay threatens a mobilisation window, because that is a survey-schedule risk wearing a marine-engineering costume. Clear ownership of who signs off which certificate – and who covers when that person is on leave – is the same assurance question that runs through offshore work, and the competence lessons drawn from positioning-related incidents apply here too.
• For chartered tonnage, verify rather than manage. Add a line to your vessel-acceptance check confirming that statutory-equipment DoCs are current to the applicable implementing regulation before the spread mobilises.

The wider point is that this overhead is fixed. A single-vessel survey operator carries the same MED certification chain, the same DoC obligation and the same notified-body lead times as a large fleet, spread across far fewer hulls. Whether that scale disadvantage is real or manageable sits inside the wider question of consolidation in the offshore survey market, and regulatory maintenance like the 10th Implementing Regulation is exactly the standing cost that favours operators able to amortise it. It is the routine, unglamorous work of keeping a vessel’s statutory paperwork aligned with the regulation in force – and the cost of getting it wrong is a certificate held and a spread standing by.
