Abstract: A design method is presented, which aims at the optimal crosssectional layout of the multilayer steel tube umbilical. The merit of the method is to improve the tension stiffness and the fatigue life of umbilical. An ...
Flexible Riser Configuration Design for Extremely Shallow Water With Surrogate Model Based Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of this paper is to study the optimization design of a steep wave configuration based on a surrogate model for an extremely shallow water application of a flexible riser. As the traditional technique of riser ...
Multi-Objective Shape Optimization Design for Liquefied Natural Gas Cryogenic Helical Corrugated Steel Pipe
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, the flexible cryogenic hose has been preferred as an alternative to exploit offshore liquefied natural gas (LNG), in which helical corrugated steel pipe is the crucial component with C-shaped corrugation. Parametric ...
Multidisciplinary Optimization Design for the Section Layout of Umbilicals Based on Intelligent Algorithm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Umbilicals, which link top floaters and subsea devices, provide control functions through electrical cables and hydraulic remote transmission. These cables are considered the “lifeline” of subsea production systems for ...
Electro–Thermal–Mechanical Coupled Analysis on Two High-Current Composite Umbilical Cable Cross Sections
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new type of umbilical cable named “high-current composite umbilical cable” is composed of electronic cables, optical cables, steel tubes, and structural strengthening components. It can be regarded as a key piece of ...
Multi-Objective Collaborative Flexibility Optimization Design of the Strengthening Layer of a Flexible Riser
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Marine flexible risers are widely used in ocean oil and gas extraction, and need to withstand environment loads (wave and current) and the large offset of the floater. Therefore, the flexible riser is subjected to tension, ...
Study of Temperature Field in Helical Carcass-Supported Flexible Cryogenic Pipes for Liquefied Natural Gas
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Helical carcass-supported composite flexible cryogenic pipes (HC-FCP) for liquefied natural gas (LNG) are critical components in floating liquefied natural gas (FLNG) storage and offloading systems. The complex cross-sectional ...
Study on Failure Prediction Methodology of Flexible Pipes Under Large Torsion Considering Layer Interaction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible pipes are distinctive multi-layer structures that are designed to resist different loads when they are utilized in severe deep-water environments. However, they lack a special structural layer to withstand torsion. ...
A Finite Element Model for Prediction of the Bending Stress of Umbilicals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Umbilical is an important equipment in the subsea production to supply a connection between the floater and the subsea well. Analyzing strength and fatigue behaviors under bending is a key requirement to assure safety. An ...
