E02 Rigid Hinged Stinger Pdf Pipe Fluid Conveyance Force The document describes the modeling of a rigid hinged stinger for pipelaying operations using orcaflex software, detailing the setup of the model, including the lay vessel, pipeline, and piggyback cable. In these examples, two different methods of modelling a simple rigid stinger are presented. both use the pipelay supports method, with one model using a simple supports geometry, and the other using an explicit method.
Stinger Handling Systems Huisman If you know the relevant stinger structural and hydrodynamic properties, you should select the flexible or flexible hydro options and input these properties. otherwise, you can opt for the rigid format, and pipelay will automatically compute default stinger properties for you. This is achieved by performing a fully coupled analysis (fca) in time domain, with capability to capture the impact of stiffness and hydro elastic properties of stinger and pipeline. Conventional method for rigid pipe. when using the s lay installation method, onboard welded pipe joints leave the vessel horizontally and are guided to the seabed over a “stinger” a structure on the back of the ship that supports the seagoing pipe string to control its bend radius. Is this a trussed stinger or rigid articulated stinger? sled segment: only one is used. a floating stinger (trussed or articulated) is subject to considerable load and risk failure at the hinge location(s). operational personnel prefers the trussed stinger as it is easier to handle offshore.

Due to the high production rate and the possibility to install concrete coated pipe, s lay is extremely suitable for pipe installation in shallow and intermediate waters. greater water depths are also possible, but require a relatively long stinger and a large vessel to support it. The active parts of the model consist of a lay vessel, the pipeline being laid, a tensioner and a stinger. the stinger is connected to the vessel using two constraint objects, to represent a hinged system. Poe pl1 is a pipe lay barge with a fixed truss stinger. the same was modified and strengthened to be used for the serica project to lay the 14” pipeline at a maximum depth of 55m. It includes both the pipe being laid and a piggybacked cable. the stinger is modeled using supports on a buoy with negligible properties. the pipe and cable are each tensioned using winches and are in contact with each other via line clamps.
