Abstract
A catamaran, adapted for use in laying a submerged pipeline, is provided with a slidable support for the pipeline, including a slightly inclined ramp integral with the awning deck of the catamaran for carrying out the operations for building the pipeline, a moveable stinger extending from the rear end of the catamaran, and an intermediate pipeline supporting element having its bow end hinged to the stern end of the ramp and its stern end pivotally hooked to the front end of the stinger. The stern end of the intermediate pipeline supporting element may be raised or lowered so that its angle of inclination may be varied and it may be locked in position at a selected angle of inclination through a castle-shaped member located abaft the catamaran and including two side frames fixed to the awning deck of the catamaran so that they straddle the intermediate pipeline supporting element and their lower ends are submerged. The frames are provided with vertically spaced pairs of opposed holes for the reception of check pins extending through holes located in the sides of the intermediate pipeline supporting element at its stern end.
