INTEGRATED STRUCTURAL ANALYSIS, DESIGN AND EVALUATION OF OFFSHORE/ONSHORE STRUCTURES ACCORDING TO THE API 4F (4th EDITION).

V E S S E L   D Y N A M I C   M O T I O N S

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.

API 4F

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

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.

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

WEIGHT DATA

High pressure mud piping, electrical cable trays, junction boxes, racking boards, tong counterweights, turning sheaves, deadline anchors, crown accessories, casing stabbing baskets and other outfitting items add weight to the derrick. Weight data is converted to masses applied at the correct locations on the derrick.
