Abstract EN
This paper deals with ship-jacket platform collisions.
An examination on NORSOK N-004 rule is carried out.
Furthermore, elastic and plastic response of jacket platform is studied.
This paper also conducts a sensitivity analysis, focusing on collision points.
Simulation models of a ductile and a rigid supply vessel were developed, as well as models of two typical jacket platforms.
Data such as collision force, kinetic energy, and deformation energy have been obtained.
Several conclusions have been drawn: NORSOK rule underestimates the resistance for certain indention, due to inaccurate description of column deformation mode.
Elastic response is extremely important in dynamic analysis of ship-platform impacts, by contributing to reducing impact loads and local energy dissipation.
Struck members are therefore subjected to impacts to a low extent, which can be regarded as result of a buffering effect.
Before a buffering effect works, a time delay exists.
This is caused because the topside has to take up adequate kinetic energy.
Striking position has an effect on dynamic behavior of platform.
High local strength is in favor of buffering an effect.
Elastic response is more significant in a flexible platform than in a sticky one.
