... in deepwater assets and over long distances remains underexplored. This paper, from the perspective of an energy company, delves into the challenges of HV Electrification, focusing on subsea cables and topside equipment, and draws parallels with Power Transmission in Floating Wind projects. Through...

... cables, which are otherwise too high with traditional High Voltage Alternating Current (HVAC) system, the Italian regulatory authority, ARERA, has already highlighted in its guidelines the importance of implementing High Voltage Direct Current (HVDC) systems, when applicable. This paper gathers all...

... the electrode cables for the execution of the measurements directly on the seabed. This entailed the need to use specifically made cable, with an extension of 50 m with respect to the position of the first electrode lying on the bottom. 1 GEOLOGICAL AND GEOMORPHOLOGICAL FEATURES The site has been investigated...

... methodology for monitoring the structural integrity of the MT based on a network of optical fiber cables (defined "sensing cable") in which both strain and temperature sensors are embedded. These sensors have been realized through Bragg technology. The measurements are based on the monitoring of the axial...

... are logged and remotely transmitted by a topside based data logger and communication systems. All together, these scientific systems require a peak power load of 270W. All such subsea systems are connected to the topside by cables, to be safely routed and protected from the offshore environmental conditions...

... Legislation regarding the emissions limits. Due to expected growth in power demand (i.e. in Crete and Rhodes), but also in order to reduce the cost of electricity and comply with the emissions limits, installation of submarine power cables to connect the islands with Continental Greece is scheduled. However...

...). Designer of HTS cables for fusion magnets actually project REBCO tapes to fall below 50$/kAm already by 2030 [30]. As soon as the price for REBCO tapes is driven by fusion below a certain threshold, presumably around 50 $/kAm, the usage of coated conductors also for other applications will start to become...

... in novel markets; regulatory compliance; and standardization for cost and quality benefits. Experience from floating production of oil and gas can assist the evolution and qualification of new methods, materials, or technologies, like anchoring, mooring and dynamic cables, and reduce FOW systems costs...

.... This paper proposes the study of the kinematic rotation of a prototype machine required to lay down an umbilical system, needed to provide the vital supply (electricity and fiber optic) from platforms or topside vessel to subsea oil and gas furniture. In the studied case, the Client asked to have a cable...

... is, to date, the most widespread electrical heating technology and has been operated for over 15 years. DEH technology is relatively easy to implement as it consists of a heating cable piggy-backed on the production line. However, has significantly low efficiency levels in the range of 25% to 60% depending...

...), but with a technology readiness level lower than AGISCO's one, that proposed an advanced solution based on already available industrial components and easily implemented up to desired size. The AGISCO proposed tool was based on the internal cable altitude-dependent pressure changes, measured using pressure transducers...

... water penetration inside motor. Power cable was changed from Galvanized to Monel Armor for high corrosiveness. Completion wise, one or double 1/2" water dilution lines were adopted, run along tubing, connected to tail pipe which run to perforations. Modification in completion metallurgy took place also...

... is determining the position of the CT BHA in the well. Surface depth measurement systems, however reliable, simply record the length of tubing conveyed into the well and do not precisely determine the position of the Coiled Tubing BHA. Previously, in operations where depth control was critical a logging cable...

A separate DEH cable riser (based on a pliant wave riser configuration) connects the FPSO topside DEH equipment...

... and delivered a system with 7000m depth rating. The use of cable design and engineering of Nexans, allowed use of 6600 VAC as a major feature to derive at absolute minimum topside equipment. To deliver a system to a client the terminations, frequency converters and other associated equipment was developed...
