Accidental Limit State of Submarine Pipeline: Trawl Gears Pull-Over Loads and Effect of Free Span
International Journal of Maritime Technology, 2017 Submarine pipelines failures lead to oil spills in water and may even lead to explosions with heavy financial and environmental damages. Trawl gear is one of the main factors in the failure of the submarine pipelines.

Influence of soil plasticity models on offshore wind turbine response
Wind Energy, Volume 27, Issue 2, Page 131-151, February 2024.Abstract While recent numerical modelling advances have enabled robust simulation of foundation hysteresis behaviour, uptake of these models has been limited in the offshore wind industry. This is partially due to modelling complexity and the unknown influence of including such soil constitutive models within a design philosophy.

An analysis of parametric instability of risers
Latin American Journal of Solids and StructuresIn this work, three catenary riser models subjected to harmonic oscillations are studied. Two are finite-element models, one studied with Orcaflex, an offshore marine system analysis software, and another one with Abaqus, a generalist structural analysis

Study on Optimization of Design Parameters for Offshore Mooring System using Sampling Method
한국해양공학회지, 2018 In this study, the optimal design of a mooring system was carried out. Unlike almost all design methods, which are based on the deterministic method, this study focused on the probabilistic method.
