ICCP system check, afloat: AnnualClass rules and the ICCP maker's schedule. SOLAS Reg. I/10 governs the bottom inspection, not the power unit.
Sacrificial anode and hull potential survey: Class- or owner-set; taken at the bottom inspectionSOLAS Reg. I/10 sets the bottom-inspection cycle for cargo ships — a minimum of two inspections of the outside of the ship's bottom during the five-year period of validity of the certificate, with no more than 36 months between any two. SOLAS sets nothing for ICCP or anodes: that survey is class- or owner-ordered and is taken while the hull is accessible, which is why it follows the bottom-inspection window rather than a cycle of its own. Whether an in-water survey may stand in for a drydock bottom inspection is a matter for the Administration and class, not something Reg. I/10 provides for.

Emergency & escape lighting

Emergency and escape-route lighting test: AnnualClass rules at the annual survey. Endurance is fixed by SOLAS Reg. II-1/43 for cargo ships — 3 hours at muster and embarkation stations and over the sides, 18 hours for alleyway, stairway, exit, machinery-space and control-station lighting — and by Reg. II-1/42 for passenger ships (36 hours, which the Administration may reduce to not less than 12 hours for ships regularly engaged on short voyages).
Low-location lighting examination and luminance test (passenger ships over 36 passengers): Weekly visual; luminance test at least every 5 years (passenger ships)Passenger ships only. SOLAS Reg. II-2/13.3.2.5.1 requires the marking and refers its evaluation, testing and application to the FSS Code Ch. 11, which points in turn to IMO Res. A.752(18). Those guidelines apply to passenger ships carrying more than 36 passengers and are written as recommendations: §9.1 that all LLL systems be visually examined and checked at least once a week with a record kept, §9.2 that luminance be tested at least once every five years with readings taken on site. ISO 15370 carries the measurement method. Nothing here is set for a cargo ship.

Who grants authorisation, and where you check it

Flag Administrations, classification societies and accreditation bodies — what each grants and the public register a buyer verifies it on. Reference, not a claim: nothing here has approved ShipCertify, and none is named as having done so.

How a UR Z17 approval works, and its limits

Approval is granted by one society, never by IACSIACS UR Z17 · InternationalZ17 6.1: the individual society audits, certifies and may list the firm in its own record.
The certificate names scope, equipment and limitationsIACS UR Z17 · InternationalZ17 6.1: type and scope of service, plus equipment types and maker names where limiting.
Renewal by audit at intervals not exceeding five yearsIACS UR Z17 · InternationalZ17 6.2: three years for thickness measurement; societies may add intermediate audits.
Manufacturer certification is a precondition in some categoriesIACS UR Z17 · InternationalZ17 5.1.1: maker evidence that the firm is licensed for those makes and models.
Approval is mandatory only where a surveyor relies on the resultIACS UR Z17 · InternationalZ17 4.2: thickness measurement, in-water survey, ultrasonic tightness testing and RIT for class decisions.
Five categories are optional unless the flag says otherwiseIACS UR Z17 · InternationalZ17 4.4: low-location lighting, PA/GA sound pressure, noise, coating testing, ro-ro door examination.
Statutory scopes depend on the society holding flag authorisationIACS UR Z17 · InternationalZ17 4.3: the society may instead accept flag, RO or other flag-acceptable approvals.
Z17 does not replace flag authorisation under MSC.402(96)IACS UR Z17 · InternationalAnnex 1 section 13 implements it, but only for flags that authorised that society.
Z17 does not replace A.761(18) liferaft station approvalIACS UR Z17 · InternationalStation approval stays with the flag and the raft maker; the twelve-month interval is SOLAS III/20.8.
Z17 is not calibration or inspection-body accreditationIACS UR Z17 · InternationalIt confers no ISO/IEC 17025 or 17020 scope, and no MED wheelmark product conformity. The ILAC and EMSA MED rows below are where those are verified.
An approval does not transfer between societiesIACS UR Z17 · InternationalEach society approves separately; Z17 8.1 lets a cancelling society inform the other IACS members.
Agents, subsidiaries and subcontractors must be declaredIACS UR Z17 · InternationalZ17 section 3 and 5.1.1: listed in the application and bound by formal contract.
The society remains accountable to the flag for the firm's workIACS UR Z17 · InternationalZ17 4.1.3: third-party work counts as the society's work under RO Code MSC.349(92).

Statutory regimes outside UR Z17

Certification, thorough examination and testing of lifting appliances and anchor handling winchesSOLAS II-1/3-13 · InternationalNew SOLAS reg. II-1/3-13 adopted at MSC 107 by Res. MSC.532(107), in force 1 January 2026; covers design, operation, inspection, testing and maintenance. Not a Z17 category — the approval route is the society and the flag.
Preparation, verification and maintenance of the Inventory of Hazardous MaterialsHong Kong International Convention on Ship Recycling · InternationalIn force 26 June 2025; each ship needs a ship-specific IHM prepared, verified and kept current to the 2023 Guidelines, Res. MEPC.379(80), with initial, additional and final surveys. Flags list IHM expert companies separately. Not a Z17 category.
Verification of emissions monitoring plans and annual emissions reportsRegulation (EU) 2015/757 (EU MRV) · InternationalVerified by an accredited MRV shipping verifier under Delegated Reg. (EU) 2016/2072 as amended by (EU) 2023/2917, accredited by a national accreditation body. Runs in parallel with the IMO fuel-oil data collection system. Neither class approval nor a Z17 category.
Servicing and calibration of 15 ppm bilge alarms and oily-water separating equipmentIMO Res. MEPC.107(49) · InternationalMEPC.107(49) gives the revised guidelines for machinery-space bilge pollution prevention equipment, requiring under 15 ppm with alarm and automatic stopping arrangements. Servicing and calibration is maker-authorised, outside Z17.
Compressed breathing-air purity analysis for SCBA and EEBD charging installationsInternationalThe laboratory scope the Z17 SCBA category explicitly excludes: periodic analysis of the ship's charging-compressor air for carbon dioxide, carbon monoxide, oil, particles and water vapour to EN 12021. An ISO/IEC 17025 laboratory activity, never conferred by a Z17 SCBA approval.

Where approvals and standing are published

Each society's own record of approved service suppliersIACS UR Z17 · InternationalZ17 6.1 wording; there is no central IACS list, so the check is society by society.
IACS members' QSCS statements of complianceIACS · United KingdomIACS publishes per member a Statement of Compliance with QSCS, an ISO 9001 certificate and an IQARB Factual Statement. There is no artefact called a QSCS certificate — asking for one by that name will not find it.
DNV Approval FinderDNV · NorwayDNV's public search for type approval and materials and components certificates — products and their manufacturers. It self-identifies as the CMC Approval Finder and is not a UR Z17 service supplier register.
EU recognised organisations list under Regulation (EC) No 391/2009European Commission · InternationalSocieties recognised EU-wide; the list is published in the Official Journal and by EMSA.
EMSA MED PortalEuropean Maritime Safety Agency · InternationalThe wheelmark register: all approved marine equipment products that may be carried on EU Member State-flagged ships under Marine Equipment Directive 2014/90/EU.
ILAC MRA Signatory SearchInternational Laboratory Accreditation Cooperation · InternationalWhere ISO/IEC 17025 calibration and testing, ISO/IEC 17020 inspection-body, ISO/IEC 17043 and ISO 17034 accreditation is verified; signatory bodies are listed with scope, and accredited bodies are searchable by specific test or inspection.
IMO GISIS recognised organisation recordsInternational Maritime Organization · InternationalShows which organisations a flag has authorised and for which statutory scope.
EquasisFrench Ministry in charge of the Sea and Fisheries · InternationalFree public ship-safety database, registration only; ship and company search with an editorial board including EMSA and several national maritime authorities. Where a ship's society and safety record are read before a fixture.
Paris MoU RO Performance ListParis Memorandum of Understanding on Port State Control · InternationalGrades each recognised organisation High, Medium or Low on three years of rolling inspection and detention data; published annually alongside the flag White, Grey and Black Lists. The 2025 lists were published on 2 July 2026.
Tokyo MoU performance listsTokyo Memorandum of Understanding on Port State Control · International22 member authorities across the Asia-Pacific; publishes current lists of flags and recognised organisations, high-performing and under-performing company lists, and an under-performing ships list.
Black Sea MoU and Mediterranean MoURegional port State control memoranda · InternationalTwo of the nine regional PSC MoUs modelled on Paris, with Tokyo, Viña del Mar, Caribbean, Indian Ocean, Abuja and Riyadh; they govern inspection in the Black Sea, Marmara, Aegean and Mediterranean ports where much of this tonnage calls.
Liberian Registry authorised service provider listsRepublic of Liberia Maritime Administration (LISCR) · LiberiaPublishes named authorisation lists under its Regulations and Standards section, including Authorized Lifeboat Service Providers and IHM Expert Companies, alongside its marine notices.
Panama Maritime Authority, Directorate General of Merchant MarinePanamaAuthorises organisations to issue technical and statutory certification on Panama's behalf by numbered resolution — for example Resolution No. 106-OR-30-DGMM held by MACOSNAR. The resolution number, not a brand name, is what a buyer verifies.
Flag Administration circulars and authorised-firm listsInternationalEach flag publishes its own authorisations for MSC.402(96), A.761(18) and radio surveys. The Liberia and Panama rows above show the concrete form these take; check the specific flag, by name, every time.
