... ABSTRACT This paper presents numerical simulation of key physical properties of typical offshore dynamic power cable. Axial, torsional and bending stiffness are included, and validated by performing full-scale tests. Comparison of the results indicates the inherent relation between the complex...

... ABSTRACT Modelling alternatives for non-critical components in dynamic offshore power cables are systematically investigated with the aim to clarify the extent to which these components in finite element modelling (FEM) should be considered depending on the purpose of the analysis. Level...

... ABSTRACT The fatigue behavior of a PbSnSb alloy used in subsea power cable sheathing was studied using small- and full-scale experiments. The aim of the work was to understand the transferability between the scales and suitable testing methods. Creep phenomena are addressed by considering...

... system well. INTRODUCTION Manufacturers of subsea power cables, umbilicals, and power umbilicals are constantly being challenged to deliver products for deeper waters and for lower-temperature areas, while being highly cost-effective. This combination of technological challenges and cost optimization...

... ABSTRACT To be able to meet our customers' future needs Nexans is developing dynamic cables for deep waters. One of the main challenges with a subsea power cable in deep waters is the high topside tension caused by the weight of the cable. In order to reduce the cable weight and increase...

...-Wind, one floating power substation and power cables. The present study objectives are, thus, to assess the technical and commercial feasibilities of the TX-Wind for Hawaii offshore at ultradeep water of 1,000 m. We believe that no study of such ultradeep water floating wind with any type of floating...

... ABSTRACT A semi-submersible hybrid platform moored at a water depth of 80 m is designed to generate a total of 10 MW power combining winds and waves. A power cable transferring the generated power connected to the platform is deployed in the water with a lazy-wave shape configuration. Two...

... University of Twente, chair group Water Engineering and Management, Enschede, The Netherlands ABSTRACT The aim of this paper is to optimize power cable routing in a wind farm based on the expected morphological behaviour in the design lifetime of an offshore wind farm. Up to now methods to optimize cable...

... Abstract Bitumen is field-proved to be a highly effective corrosion protection for steel armor wires in subsea power cables, umbilicals, and power umbilicals. Bitumen's viscoelastic properties are known to influence the mechanical properties of cables, umbilicals, and power umbilicals. Still...

... Abstract During ExxonMobil Offshore Power System Reliability- B (OPSRB) qualification program, it was identified that the axial tension has a remarkable impact on the power cable bending stiffness which impacts installation loading. The test results also showed the viscoelastic behavior...
