All Planning Phases

I. Basis evaluation

• Preparation of the Design Basis with parameter (wind, wave, subsoil, loads)
• Cluster formation with sensivity analysis

II. Planning

• Determination of extrem load cases
• Pre-design / concepts of offshore foundation structures and transformer platforms
• Parameter studies, e. g. choice of offshore foundation type (Monopile, Tripod, Jacket, Gravity)
• Outline of foundations drafts and preparing mass estimation
• Verification of parameter studies for feasibility estimation
• Installation concept with driveability estimations related to existing subsoil expertises
• Transportation concepts for offshore foundations (logistic offshore wind)
• Preperation of basis for cost-effectiveness
• Consulting services in negotiations with authorities

III. Design engineering

• Design drafts on basis of planning concepts
• Preperation of structural steel solutions for offshore foundations
• Dimensioning of main parts (e. g. local joints, flanges, grouted joints)
• Preparing of mass calculations
• Basic assignment of design details and main dimensions of foundation types
• Perform of driveability estimation
• Consulting services in negotiations with auhtorities

IV. Approval planning

• Consulting services in negotiations with certifier
• Submitment of documents to certifier and audit authority
• Verifiable computations with documents
• Transport, assembling and deconstruction plan
• Reinforcement steel drawings
• Steel construction plans

V. Implementation planning

• Technical preparation of results from phases of planning III and IV
• Detailed design with verification
• Installation plans and fitting plans (reinforced concrete)
• Steel amount and parts lists
• Workshop drawings
• Welding seams

Examples of proven service packages

I. Design Basis

• Determination of design parameters from expertises
• Screening of major design loads
• Evaluation available expertise (plausibility control)
• Verifiable data basis for the whole planning of structural framework (basis to tender)

II. Cluster formation

• Determination of cluster with similar subsoil behaviour
• Safeguarding of cluster robustness by sensitivity analysis
• Minimizing of total numbers of foundation constructions from numbers of clusters

III. Parameter studies

• Variation of boundary conditions (hub height, wind turbine type, scour protection)
• Alternative solutions ond feasibility studies for foundation types of offshore-wind turbines and transformer platforms
• Prepare mass estimation
• Cost basis (fabrication, transport, installation, maintenance, deconstruction)
• Detect "relevant parameters" (park configuration, parameter, foundation type)
• Cost-effectiveness for the whole wind park

IV. Detail design with verification

• Tower and tubular joint (Jacket, Tripod)
• Grounted joint and flange joint
• Wartungsplattform
• Maintence platform
• Integration board crane
• Doorway
