ISO 29400:2020

Overview

ISO 29400:2020 - Ships and marine technology - Offshore wind energy - Port and marine operations provides comprehensive requirements and guidance for planning, engineering and executing port and marine operations for offshore wind farms. The standard covers documentation, engineering of components, systems and equipment, and the safe methods and procedures needed for loadout, offshore transport, installation, offshore commissioning, operation & maintenance, component exchange, repairs, and decommissioning or redeployment.

The document applies to a wide range of offshore structures including lattice steel foundations, concrete gravity base structures (GBS), piled and mixed foundations, subsea templates, towers, nacelles, blades, floating turbines, self-elevating units, launching systems and array/export cables. It explicitly excludes onshore fabrication (non‑marine exposure), road transport onshore, and diving operations.

Key topics and technical requirements

• Planning & organization: project and operational organization, communication, quality assurance and administrative procedures.
• HSSE & risk control: Health, Safety, Security and Environment (HSSE) planning, risk management techniques, job safety analysis and environmental impact studies.
• Documentation & certification: RAMS (Reliability, Availability, Maintainability, Safety), document numbering, operational schedules, contingency philosophy, emergency response coordination and as‑built/post‑construction files.
• Metocean requirements: wind, waves, swell, currents, temperature, marine growth, design criteria vs operational limits, return periods, weather windows, forecasts and on‑site monitoring.
• Marine operations engineering: structural integrity calculations for transport and loadout, transport frames and equipment, intermediate storage area design, pre‑assembly area requirements and procedures.
• Marine warranty & approvals: role and scope of Marine Warranty Surveyors (MWS), certification and national authority approvals.
• Equipment & vessels: specification and assessment of marine vessels, major lifting and handling equipment and launching/installation systems.

Practical applications and users

ISO 29400:2020 is intended for organizations involved in offshore wind port and marine operations, including:

• Offshore wind developers and owners
• Marine and structural engineers
• Port authorities and terminal operators
• Marine contractors, heavy‑lift and logistics providers
• Marine Warranty Surveyors and certification bodies
• HSSE and project planners, metocean analysts

Use cases include preparing port acceptance, loadout and transport plans, defining operational limits and weather windows, creating contingency and emergency procedures, and ensuring regulatory and warranty compliance during installation, maintenance and decommissioning.

Related standards

Standards commonly referenced alongside ISO 29400:2020 include industry codes and standards for wind turbines, offshore structures, metocean analysis and maritime safety (for example IEC wind turbine standards, ISO/IMO marine conventions and ISO 19901 series for offshore structures). These help integrate technical design, environmental and safety requirements into port and marine operation planning.
