What is ISO 29400 about?
ISO 29400 provides comprehensive requirements and guidance for the planning and engineering
of port and marine operations of offshore wind farms, encompassing all documents and works related to such operations, e.g., the design and analysis of the components, systems, equipment, and procedures required to perform port and marine operations, as well as the methods or procedures developed to carry them out safely.
ISO 29400 is intended to be comprehensive, covering all relevant information related to port and marine operations necessary for loadout, offshore transport, installation, offshore commissioning works, operation and maintenance, component exchange, repair operations, and decommissioning or redeployment of offshore wind farms.
ISO 29400 is applicable to port and marine operations for offshore structures including:
- Lattice structure foundations made from steel
- Concrete gravity-based structures (GBS)
- Piled steel foundation or mixed steel and concrete foundation structures
- Subsea templates and similar temporary structures or installation aids
- Steel or mixed material towers, nacelles, and blades forming part of the wind turbine generators (WTG)
- Floating turbines moored to the seabed
- self-elevating offshore units for offshore substations or offshore accommodations platforms
- Launching systems at sea from quayside or onshore
- Array cables within the wind farms as well as export cables connecting the wind farm to the grid
ISO 29400 is also applicable to modifications of existing structures, e.g., installation of additional modules, exchange of components or decommissioning, and marine operations during the service life of the wind farm related to the technical maintenance works.
Note: ISO 29400 is not applicable to the following operations:
- Construction activities, e.g. In a fabrication yard onshore, where there is no exposure to the marine environment
- Road transport onshore
- Diving
Who is ISO 29400 for?
ISO 29400 on offshore wind energy is useful for:
- Ships and marine manufacturers
- Port products manufacturers
- Design engineers for port applications
- Quality control personnel for marine applications
Why should you use ISO 29400?
ISO 29400 helps in achieving reliability levels appropriate for offshore wind farm components, whatever the type of structure and the nature or the combination of materials used may be.
ISO 29400 helps you in providing comprehensive requirements and guidance for the planning, engineering and safe execution of port and marine operations for all types of offshore wind farm components including cable-laying and burial operations and installation and operation of floating turbines moored to the seabed.
Adopting ISO 29400 helps you in providing the principles of and requirements and guidance for, port and marine operations associated with foundations, substructures, WTG, cables, and topsides installed in offshore wind farms, from the point of view of planning, engineering, construction, and documentation
ISO 29400 ensure that port and marine operations are conducted within defined and recognized safety and reliability levels.
What’s changed since the last update?
BS ISO 29400:2020 supersedes BS ISO 29400:2015. BS ISO 29400:2020 includes some technical changes with respect to BS ISO 29400:2015. These include:
- Clause 3: terms and definitions revised; new entries inserted
- Clause 7, “Metocean requirements”: fully revised
- Clause 20, “Cable loadout and offshore transfer”: new subclause added
- Revisions made throughout most other clauses
- Annex A: revised
