The Suspension System Design for the Tensioner of the Ocean Pipeline Barge

Abstract

Based on the variable stiffness elastic principle, completed three series of variable stiffness elastic suspension system design for the ocean pipe laying tensioners, effectively improved the clamping ability of the tensioner when the local pipe diameter is changing, and improved the overall stress environment of the tensioner. Established non-linear mathematical model and got the impact of instant response and response force by using the Matlab software.

An apparatus design and testing of a flexible pipe-laying in submarine context

“…Based on crawler arrange form and quantity (Sun et al, 2008), tensioner (Guo et al, 2011;Wang et al, 2011) can be classified as two-crawler up-dower form (a), two-crawler horizontal form (b), three-crawler form (c) and four-crawler form (d). Four-crawler tensioner (Li, 2012) has larger tension force, for large-tonnage flexlay system, four-crawler tensioner should be selected.…”
