A Design Basis Report is a foundational document in an offshore wind project that outlines the technical criteria, standards, and methodologies used to guide the project’s engineering, procurement, and construction phases.

It establishes a clear framework for the design of all major components, ensuring that the project meets regulatory, environmental, and technical requirements. DB report is often a prerequisite for regulatory approvals, project financing, and risk assessments, as it provides a comprehensive, structured approach to the entire project lifecycle.

SanCo´s Technical Audit services add value to our Clients by enabling senior management to make informed decisions that will push the project in achieving its milestones.

SanCo supports developers, insurance companies, investors and banks, law firms, technology developers, manufactures and public bodies in protecting theirs assets, investments and ownership.

Design Basis Chapter	Contents
Standards and Regulations	Applicable Standards: Lists relevant international and national standards (e.g., IEC, ISO, DNV-GL, ClassNK, etc), codes, and guidelines governing offshore wind projects. Regulatory Requirements: Summarizes the regulatory framework for the project’s location, including environmental, safety, and operational requirements. Certification and Compliance: Specifies required certifications and agency approvals needed for the project’s design and construction.
Site Conditions	Metocean Data: Presents data on wind, wave, current, and tidal conditions, as well as extreme weather events. Geotechnical and Geological Conditions: Provides detailed information on seabed characteristics, soil types, sediment profiles, and geological hazards. Environmental Conditions: Summarizes local environmental data, including temperature ranges, salinity, and potential risks from marine growth and corrosion. Seismic and Natural Hazard Data: Includes any seismic data or tsunami risk assessments relevant to the area.
Design Criteria for Main Components	Turbine Design: Outlines design specifications for turbines, including wind loading, cut-in and cut-out speeds, and rotor diameter. Foundations: Specifies foundation types (e.g., monopiles, jackets, or floating structures), loads, and soil interaction parameters. Substructure and Transition Pieces: Provides criteria for substructure design, considering wave loading, fatigue, and corrosion protection. Electrical Systems and Cables: Details the design basis for inter-array and export cables, including cable routing, voltage requirements, and thermal constraints.
