Design and analysis of jackets and subsea structures
Our experience covers:
- Marginal platforms, for example, monotower
- Conventional four-legged jackets
Our core engineering staff is fully conversant with all common North Sea design requirements such as DNV, NORSOK, API, ISO and Danish codes.
Services
Our jacket services include:
- Feasibility, and conceptual and detailed design
- Structural analysis covering load-out, lift, installation, in-place and fatigue analysis
- Dynamic ship impact analysis
- Wave-in-deck load scenarios
- Finite Elements Method (FEM) analysis of joints
- Dynamic pushover analysis (large deflection/rotation analysis)
- Inspection planning of jackets (fracture mechanics, member importance analysis)
- Assessment of existing structures (re-analysis and member strengthening, for example, grouted joints)
- Structural integrity management
- Construction supervision
- Decommissioning
Structural analysis software
At Ramboll, we focus on continuous technology development. This has helped us maintain our position as the leading Danish offshore consultant – offering the most effective, detailed and advanced design and analysis available.
We carry out jacket structure analyses using our cutting-edge structural analysis software ROSAP and RONJA – including advanced analysis and post-processing facilities. We apply FEM programs, such as ANSYS/LS-DYNA, for the analysis of critical joints or complex structures.
