... reduce the maximum stress level near TDZ (touch-down zone). It is because the riser motion can be isolated from the motion of the floater by the intermediate sag and arch members in the lazy-wave configuration. The general performance of SCRs and LWSCRs is directly compared under the same environmental...

... ABSTRACT: The paper describes a simple and quick method to determine the static behaviour of pipeline free spans. The method provides such data as sag at midspan, slope at shoulders, lifted length and slip length at each side of the span, effective axial force, pipe wall force (= "true" axial...
