When do flags/classes require OEM-specific authorization?

OEM-specific authorization is usually required when the job can affect safety-critical performance or when the maker restricts servicing to approved parties. In practice, flags and class ask for OEM-specific authorization in these cases:

  1. Critical repairs or modifications: for example release gear parts replacement, brake/winch overhaul, structural work, hydraulic/control changes, or any reset outside maker limits. Therefore, class may request maker-approved procedures or an OEM-authorized service provider.

  2. Maker restrictions: manuals, bulletins, and parts policies may state “authorized personnel only”. In addition, some makers require OEM kits, special tools, or maker acceptance for traceability and warranty.

  3. Flag/Class circulars and local practice: requirements can vary by registry and class office. Consequently, the same scope can be accepted in one flag and questioned in another.

However, you still want a predictable outcome. So, we map the scope to SOLAS III/20 and IMO MSC.402(96), then we confirm whether OEM-specific authorization is mandatory for your exact make/model and serial range. As a result, the documentation pack stays class-ready and PSC-friendly.

Action:
Send make/model, serials, last service reports, incident history, and planned scope (repair, overhaul, or modification). Then we confirm thresholds, align with class/flag attendance if needed, and plan the fastest compliant execution for port calls and shipyards in Klaipėda, Riga, Tallinn, Gdańsk/Gdynia, as well as Nordic and North Sea hubs.

Docs:
Maker manuals and service bulletins; Class/Flag circulars; SOLAS III/20; IMO MSC.402(96) (verify acceptance with Class/Flag where applicable).
