IACS Unified Requirements (UR) Rahmen

IACS Unified Requirements (UR) are common technical standards adopted by all 12 IACS member societies. URs ensure consistent technical requirements across ABS / LR / BV / DNV / ClassNK / KR / CCS / RINA / RS / IRS / PRS / CRS.

IACS UR structure: Each UR has alphanumeric code (UR E1, UR M1, etc.) + scope + applicable vessel types + technical requirements + test methods. Maintained by IACS Panels (Hull, Machinery, Electrical, etc.).

IACS UR E series (Electrical): E1 (general), E5 (cable), E6 (semiconductor converters), E7 (battery systems), E10 (test procedures), E11 (computer-based systems), E15 (uninterruptible power), E17 (harmonic distortion), E21 (cold iron shore power), E22 (cyber security onboard), E26 (cyber security for ships), E27 (cyber security for ports).

IACS UR M series (Machinery): M1 (general), M2 (boilers), M3 (main propulsion), M4 (auxiliary machinery), M5 (pumps), M6 (piping), M8 (refrigeration), M9 (internal combustion engines), M10 (gas turbines), M11 (steam turbines), M13 (propulsion reduction gears), M16 (gearing), M25 (hydraulic systems).

UR implementation: Mandatory for IACS members to apply UR requirements for classed vessels. Members can add own interpretations but cannot relax UR requirements. UR updates approved by IACS Council (12 society votes).

UR testing: UR specifies testing requirements for components + systems. Testing per UR is recognized by all IACS members without re-testing.

UR for protective cases: UR M1 (general machinery components) covers enclosure + housing + structural. UR E22 / E26 / E27 (cyber security) requires tamper-evident enclosures + access control for cyber-sensitive equipment.

B2B recommendation: For globally-marketed marine B2B equipment, target IACS UR compliance in addition to one class society Type Approval. Mutual recognition ensures global market access.

Klassifizierungsprüfungsprozess

Class survey is the inspection process by which class society verifies vessel or equipment compliance with its rules. Surveys occur during construction, periodically during service, and after significant modifications.

Construction survey (new building): Class surveyor attends construction at yard. Verifies material certificates, welding procedures, fabrication tolerances, NDT, hydrostatic test, sea trial. Issues Class Certificate (e.g., ABS Class Certificate A1 + AMS).

Initial survey: First survey of new vessel before entering service. Includes verification of design, materials, construction, equipment testing. Result: Class Certificate issuance.

Annual survey: Light survey performed each year. Visual inspection of accessible areas, verification of operational systems, marking legibility check.

Intermediate survey: Survey between 3rd and 4th annual (typically year 3-4). More thorough than annual. Includes NDT of selected areas (typically 50% of critical welds).

Special survey (renewal): Comprehensive survey performed every 5 years (or per class rules). Full NDT of all structural welds, hydrostatic test of pressure vessels, sea trial, certification verification.

Continuous survey (machinery): Continuous survey of machinery systems (not annual). Surveyor attends scheduled maintenance + overhauls. Alternative to scheduled surveys for machinery.

Lay-up survey: Survey for vessel in extended lay-up (idle for >3 months). Special procedures to prevent deterioration during lay-up. Reduces survey scope during lay-up.

Modification survey: Survey after significant modification (engine change, structural change, equipment upgrade). Verifies compliance with current rules (not the rules at original build).

Damage survey: Survey after damage (collision, grounding, fire, machinery failure). Determines scope of damage, repair procedure, re-certification path.

Surveyor authority: Class surveyor can order corrective action, suspend work, recommend withdrawal of class. Surveyor decision is binding for classed vessel.

Survey timing: Survey due dates are part of class record. Operating beyond survey due date without survey completion may result in class suspension (vessel cannot trade).

B2B recommendation: For marine-bound B2B equipment, coordinate installation timing with class survey schedule. Equipment manufacturer must support surveyor inspection (documentation, access, testing).

Klassifikationszertifikatstypen

Class society issues various certificate types for vessels, equipment, and components. Certificate types differ between class societies but share common purposes.

Class Certificate (vessel): ABS Class Certificate A1 + AMS, LR Class Certificate 100A1, BV Class Certificate I + HULL, DNV Class Certificate +1A1. Issued after initial survey. Valid for 5 years (renewable).

Short-term Class Certificate: For vessels under 5 years from construction. Simplified survey scope. Renewal at 5 years triggers full special survey.

Class Maintenance Certificate: Issued after each annual / intermediate survey. Confirms current class standing.

Class Status Report: Periodic report to owner / flag state / charterer confirming current class status. Used for vessel sale, charter, insurance.

Equipment Type Approval Certificate: For equipment manufacturers. LR / BV / ABS / DNV / ClassNK Type Approval. Valid 5 years, renewal + surveillance.

Equipment Design Approval Certificate: Less rigorous approval. Engineering review only, no factory audit. For low-risk products.

Welding Procedure Approval: For welding procedures used in vessel / equipment construction. Per IACS UR W3 + UR W4.

Forged Part Certificate: For forged components (shafts, propellers, anchors). Per class rules + IACS requirements.

Pressure Vessel Certificate: For pressure vessels (boilers, heat exchangers, pressure tanks). Per ASME BPVC or PED + class rules.

Hazardous Area Equipment Certificate: For Zone 1 / Zone 2 equipment. ATEX 2014/34/EU or IECEx + class society verification.

Statutory Certificate: For flag state / port state compliance. SOLAS, MARPOL, Load Line, COLREG, etc. Issued by flag state administration or Recognized Organization (RO = class society on behalf of flag).

IF applicable, Marine Equipment Directive (MED) / Wheelmark: For statutory marine equipment (liferaft containers, lifejacket cases, line-throwing appliances, navigation lights). MED 2014/90/EU + Wheelmark issued by EU Notified Body (typically class society).

B2B recommendation: For marine-bound equipment, target: Type Approval Certificate (most important) + Marine Equipment Directive Certificate (for safety equipment) + Statutory Certificate (if requested by flag state).

Klassifizierungsprüfungskosten + Zeit

Class survey cost varies significantly by vessel type, size, complexity, survey scope, and class society. Typical cost ranges are listed below for B2B planning.

Annual survey cost (vessel): Small vessel (under 24m) $1,500-3,500. Mid-size vessel (24-80m) $3,500-9,000. Large vessel (80m+) $9,000-25,000. Higher for offshore vessels (OSV / MODU / FPSO) due to complexity.

Intermediate survey cost: 1.5-2x annual survey cost. Plus NDT cost (typically 30-50% of survey cost).

Special survey cost: 3-5x annual survey cost. Plus NDT cost (typically 50-100% of survey cost). Plus docking / dry-dock cost (separate from survey).

Initial / new building survey: Typically 3-5% of vessel construction cost. Distributed over construction period (typically 18-36 months).

Equipment Type Approval cost: Application $1,500 + engineering review $5,000-25,000 + type testing $10,000-100,000 + factory audit $3,000-10,000 + annual surveillance $1,500-6,000 + renewal $3,000-7,000. Total first-time $20,000-150,000.

Survey time: Annual survey 1-3 days (in port). Intermediate survey 2-5 days. Special survey 5-15 days (depending on scope). Initial / new building 18-36 months (distributed).

Docking cost (separate): $50,000-500,000+ depending on vessel size + dry-dock location. Required for special survey of underwater hull + propeller + cathodic protection.

Cost optimization: Continuous survey for machinery (replaces scheduled survey). Pre-arranged survey scope with surveyor. Use approved third-party for NDT.

B2B relevance: Class survey cost is borne by vessel owner / operator, not directly by equipment supplier. However, supplier may need to support survey (engineer of FW attendance, documentation, sample units).

B2B recommendation: For equipment support contracts, include survey support in the price (typical $3-10k per part for documentation support + on-site engineer). Coordinate survey schedule with manufacturer engineering team.

Schutzkoffer-Korrelation

Protective cases used in marine / offshore / naval / class society-classed installation must be designed for harsh marine environment AND meet class society Type Approval requirements when applicable.

Class society requirements: For classed vessel installation, inner case typically requires IACS Type Approval (any member). For non-classed vessel, national approval or manufacturer specification may suffice.

Marine environment: Salt mist (IEC 60068-2-52, 504h), vibration (IEC 60068-2-6, 4 g RMS swept sine), temperature (-25°C to +55°C marine / -40°C to +70°C harsh), humidity (IEC 60068-2-78, 93% RH 55°C), inclination (IEC 60092-504, 22.5° static), EMC (IEC 60945 marine + IEC 60533 industrial).

Material selection: Stainless steel 316 (1.4401) for structural, aluminum 5083 / 6082 for weight-sensitive, engineering plastic (PP / PE / PA / PPS) for chemical resistance, EPDM / silicone for sealing. All materials must be marine-grade salt mist-resistant.

Gasket + sealing: Silicone or EPDM gasket, IP66 or IP67. Pressure equalization valve (Gore-Tex or similar) to prevent pressure differential across sealed case during temperature changes.

Latches + hinges: Stainless steel 316 hardware with positive locking + secondary retention. Tested for vibration (4 g) + shock (30 g marine).

ATEX / IECEx: For hazardous area marine environments (Zone 1 on tankers, Zone 2 in engine rooms), ATEX 2014/34/EU or IECEx certification required in addition to Type Approval.

MED / Wheelmark: For statutory safety equipment (liferaft containers, lifejacket cases, line-throwing appliances), MED 2014/90/EU + Wheelmark in addition to Type Approval.

Marking: Inner case marked with class society Type Approval (LR / BV / ABS / DNV / etc.) + manufacturer symbol + serial number + certificate number + manufacturing date. Compatible with vessel class records.

Quality system: Manufacturer certified ISO 9001 + IACS QSCS for marine equipment. Unit traceability test log embedded in manufacturer records.

Survey support: For class survey, manufacturer provides engineer + documentation + sample units. Pre-arrange survey support scope in B2B contract.

B2B recommendation: For 2026 marine-bound equipment, supply protective case with: IACS Type Approval (any member) + ISO 9001 + IACS QSCS + IP67+ + salt mist tested (504h) + EMC compliant (IEC 60945) + ATEX/IECEx (if hazardous area) + MED Wheelmark (if safety equipment) + serial-tracked marking + operator-specific markings + survey support scope in contract.
