Offshore Wind Energy

ISO 29404:2015 specifies content and format of the messages initiating and controlling the physical movement of wind turbine generator (WTG) components from suppliers to the construction site during the construction phase as well as for repair and maintenance purposes. ISO 29404:2015 is applicable to all organizations involved in the production, transportation, storage and installation of WTG parts and related components. This International Standard is not intended to be applied to substations. Messages described in this International Standard covers only the operational aspects of logistics and therefore this International Standard will represent only one aspect of the entire information flow. ISO 29404:2015 does not specify the technical implementation of appropriate IT products. It rather provides an approach based on the EPC Information System (EPCIS) standard and describes the usage of extension mechanisms provided by the EPCIS standard for the exchange of information in the offshore wind supply chain. It aims at standardizing the exchange of essential logistic information. This International Standard specifies elementary informational needs of involved parties in the offshore supply chain and defines mechanisms for the exchange of this information via the EPCIS. Due to the high degree of specialization along different offshore supply chains, partners exchanging information might require mechanisms for personalizing according to their individual demands. The underlying extendable EPCIS concept allows end users and industry consortiums to extend and to refine the information exchange. These extensions might go far beyond the basic information exchange described in this International Standard.

This document 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. This document 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. This document is applicable to port and marine operations for offshore structures including: — lattice structure foundations made from steel; — concrete gravity base 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 quay side or onshore; — array cables within the wind farms as well as export cables connecting the wind farm to the grid. This document is also applicable to modifications of existing structures, e.g. installation of additional modules, exchange of components or decommissioning, and to marine operations during the service life of the windfarm related to the technical maintenance works. It 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.
