Partially Displacement Controlled conditions in the overbend: During S-lay pipeline installation

The S-lay pipeline installation method is characterised by its fast installation process and its application in all water depths. Offshore standards and design codes provide local buckling checks for combined loading criteria for load controlled and displacement controlled conditions, where a load controlled condition is defined as a case in...

Pushover analysis of a fixed steel offshore platform - Part I: Beam-column and strut elements in the INTRA program. Part II: Piles and pile groups under extreme loads

Part I: The computer program INTRA models the collapse behavior of trusswork offshore structures with the aid of two types of elements: 'Beam-column' elements, designed to simulate bending dominated failure of structural members, and 'strut' elements, that can represent normal force dominated failure. The behavior of both types of INTRA elements...
