Ships and other marine structures are exposed to various environmental loads, such as those from wind, wave and current. The interaction between a marine structure and the environmental loads must be understood in order to optimize design and develop groundbreaking concepts. To ensure that your marine assets can withstand extreme or changing environments, we offer a range of services.
Improve stress analysis validation and assessment by combining traditional stress reporting with stress analysis visualization. Display your structural member stress results graphically and perform post-analysis member and tubular joint code checking to international design codes. Display shear force and bending moment diagrams.
Predict behaviour of a platform or topside structure with comprehensive analyses of the global response, linear static analysis, estimation of dynamic amplification factors, time domain simulations in Riflex or SIMA, frequency domain analysis, hydrodynamic analysis in Wadam. Use integrated models to calculate the wave, wind and current effect.
Import real time offshore structural motion data and then calibrate numerical design tools to comply with the full-scale vessel motions. 7Waves also perform static structural analysis featuring automatic model generation and steel code checking for a range of design and loading conditions. Produce detailed stress analysis reports to verify the structural integrity. Improve offshore structural design, quality, and design code compliance.
Comply with offshore design codes by calculating complex variable stress concentration factors (SCF). Assess wind and wave fatigue using standard or user-defined S-N curves. Re-design fatigue hot spots by strengthening surrounding area or soften the critical detail.
Typical fatigue projects are to ensure the structural integrity of a flare tower, offshore wind tower grillage, global fatigue calculations of ships and other marine structures, and local fatigue calculations of structural details.
Ensure structural compliance using DNV GL’s built-in code checking tools. Filter results for critical conditions. Optimize design and configuration for compliance to numerous current and past international codes including API, AISC, EC, ISO, DNV GL, and NORSOK. Deliver compliance documentation.
