Abstract: Fatigue of welded fixed offshore platforms is a primary design and operational concern. Environmental, fatigue data, and method uncertainties, as well as inspection and repair activities, are major parameters that influence ...

Abstract: The effect of increasing water depth on the performance of deep water tendons of tension leg platforms (TLP) is examined. Equations to determine limits on water depths for tendon systems based on strength and hydrostatic ...

Abstract: During construction of an oil tanker loading terminal in the northern Arabian Gulf, two vertical, singly standing piles failed due to fatigue damage in girth butt welds near the mudline. The failures were reported ten days ...

Abstract: An analytical model of a vertical, singly standing pile is constructed to study the mechanism by which fatigue damage is produced in girth butt welds near the mudline. Top restraints are known to have been present on the ...

Abstract: Laboratory fatigue tests were performed on girth butt weld specimens taken from both vertical piles and batter piles salvaged from the terminal. Specimens were selected to be representative of welds found to be acceptable ...

Abstract: Motion response calculation procedures are described for a vertical, singly standing pile with no top restraint. Discussion is directed to: (1) Sea state energy distribution versus frequency; (2) hydrodynamic force ...
