VESSEL DYNAMIC MOTIONS

PSE PETROLEUM STRUCTURAL ENGINEERING® SOFTWARE

VESSEL DYNAMIC MOTIONS

In the PSE Petroleum Structural Engineering® software, vessel dynamic motions are defined according to API 4F Specification for Drilling and Well Servicing Structures.

The inertial forces due to the vessel dynamic motion as well as radial, tangential and translational forces due to the acceleration of masses attached to the drilling structures have a significant influence on design and reliability.

In various production wells, the offshore drilling structures are located on top decks of vessels, semisubmersible or floating hulls. Vessel motion includes roll, pitch and yaw rotations and heave, sway and surge translations.

INERTIAL FORCES

The PSE software computes the inertial forces due to the vessel dynamic motion as well as radial, tangential and translational forces due to the acceleration of masses attached to the drilling structures. These forces have a significant influence on the structural design and reliability of offshore structures.

The PSE software accepts three types of user input in order to estimate the inertial forces induced by the vessel dynamic motions:
– Linear displacements, angular rotations and time periods 
– Linear and angular velocities and accelerations 
– Linear accelerations at two points in the vessel which are converted to linear and angular accelerations by the program.

KEY features

The PSE is a structural engineering software solution for the analysis, design and rehabilitation of drilling structures including drilling masts, derricks and substructures.
