Review and Assessment of Model Experiment and Structural Calculations for COSL Innovator
Review and Assessment of Model Experiment and Structural Calculations for COSL Innovator
Overview
Engineering IDS conducted a review of model experiment results from 2016 and assessed structural calculations for COSL Innovator. The study aimed to evaluate the feasibility of reducing the established design loads and identify opportunities to decrease conservatism in existing assessments while ensuring compliance with updated regulations.
This project was successfully executed under the leadership of Terje Olsen, a highly experienced and skilled project manager at COSL Drilling Europe. His expertise in structural integrity and hydrodynamic assessments ensured a well-structured and efficient execution of the study.
Objective
The project assessed model experiment results to verify slamming loads, explored potential reductions in design loads using updated statistical methods, and ensured alignment with the regulatory requirements.
Scope of Work
Review and verify slamming loads from previous model experiment.
Estimate new design loads using alternative extreme value distributions.
Assess the impact of trim adjustments on wave impact loads.
Methodology
The study applied advanced statistical analysis and updated hydrodynamic assessment techniques:
Extreme Value Distributions: Alternative distributions, such as tail-fitted Weibull and Generalized Pareto, were used to estimate slamming loads.
Trim Effects: The influence of trim on wave impact loads was analyzed based on model experiment data.
