SELF-ALIGNING SUBSEA STRUCTURES

摘要

A subsea assembly comprises a first structure (1) including a plurality of substantially parallel guide posts (4) and a second structure (2) comprising a support and depending therefrom a plurality of tubular receptacles (12) each positioned for fitment on a respective one of the guide posts. At least one of the receptacles includes a plurality of longitudinally disposed semi-elliptical springs (15) disposed to engage the exterior of the respective guide post (4) and thereby to axially centre the receptacle with respect to the guide post. In a converse arrangement at least one of the posts (4) carries a plurality of longitudinally disposed semi-elliptical springs (15) disposed to engage the interior of the respective receptacle (12) and thereby to axially centre the receptacle with respect to the guide post.
