Abstract
Spring systems for subsea applications and equipment projects for the oil and gas industry are preferably manufactured from composite materials and include at least one pair of springs consisting of a first spring component and a second spring component, mounted so as to offer a first central contact region and double curvature and rebound areas forming a coupling. The pair of springs are thus, self-centering.
