ON THE FATIGUE STRENGTH OF BRACE CONNECTIONS IN SEMI-SUBMERSIBLE OFFSHORE STRUCTURES

Brace connections in the tubular structures of semi-submersible offshore rigs have various types of reinforcement to ensure adequate fatigue strength, an important consideration for such structures. This paper presents some highly fatigue-resistant connections recently developed for this application, and describes a fatigue-strength assessment method for the connections. With these new connections, it is possible to limit the stress concentration factor to less than 2.0 for welds at the bracket toes and intersections, and this should give a fatigue life above the endurance period of 20 years. A test programme has confirmed the integrity of these connections.
