Riser Support Structure for Support of Flexible Risers and Umbilicals

Offshore Technology Conference Asia, 2016
Abstract Mid-water arches are often used for supporting flexible risers and umbilical's from floating structures onto seabed. If the structure needs to support a number of flexible risers and umbilicals located at a site which is prone to soil liquefaction during seismic conditions, then the selection of an appropriate foundation system ...

HORA Hinge-Over Riser Assembly Riser System

Day 1 Mon, May 01, 2017, 2017
Abstract HORA (Hinge-Over Riser Assembly) is a new riser system that improves the traditional Free Standing Riser (FSR). The system includes an articulated horizontal connection located at the base structure, eliminating the requirement for a subsea base jumper between the flowline and riser needed with the conventional FSR.

Cables for vertical risers

Electrical Engineering, 1951
VERTICAL RISER CABLE is used for power distribution systems over 100 feet in height, which might be found in tall buildings, mine shafts, and tunnels. It is distinguished from conventional cable by the need for incorporating in its design some method of supporting the weight of cable and insulation.

Instability of a vertical riser in the wake of an upstream vertical riser

Applied Ocean Research, 2010
The static solution and its associated dynamic stability of a vertical riser situated in the wake of an upstream riser is investigated in the paper. Both the upstream and downstream risers are top-tensioned and pinned at the bottom ends on the seabed. Due to the wake effects, the downstream riser is subject to mean lift force as well as drag along its ...

Effect of Riser-Seabed Interaction on the Dynamic Behavior of Risers

2017
In recent years, the production of oil and gas has been developed in deep water depths which exceed 500m. Deep water developments are being followed strongly in different parts of the world (Caspian Sea, Gulf of Mexico, etc.). The movement of floater causes severe stress at the touchdown point (TDP) in steel catenary risers (SCR). The main objective of
