Abstract: In order to study dynamic ice force induced by icestructure interaction, we adopted the most reliable method to directly measure ice force on fullscale structure. This paper mainly demonstrates the qualitative description ...

Abstract: Deep water pipeline installations by Slay present many challenges, especially in the overbend section. The Slay requires a long curved and stiff stinger to support the pipeline weight. The interaction between the overbend ...

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 ...

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 ...

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 ...

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 ...

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 ...

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. ...

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 ...

Abstract: Due to the complexity of ocean environmental loading models and the nonlinearity and empirical parameters involved in hydrodynamic numerical modeling and model testing, many uncertainties still exist in the design and ...
