Definitions

  • the present invention generally concerns the field of providing utilities such as electric power from shore to floating vessels.
  • apparatus including a cable management system for storing electrical cables.
  • Examples may have particular use in applications for feeding power from an onshore power grid through flexible cables to a floating vessel.
  • the apparatus may perform both at surface splash zone and for subsurface and subsea applications.
  • Shore power is established to achieve a greener, less polluted, and less noisy port environment. It is applied in ports around the world, and has a significant positive effect on local C02, particular matter SOT and NOX emissions. This environmental benefit happens as the vessels can turn off their onboard diesel power generator, when connected to onshore clean power supply.
  • Quays are often congested spaces with a lot of activity ongoing both when floating vessels are moored and in cases where vessel is not present.
  • An increased demand for shore power to floating vessels is imposed by governments all around the world. Today this is normally done by installing equipment such as cabinets, cable reels and cable towers on the quay front. This often diminishes the quay flexibility and often make standard operation such as craning and forklift operations difficult to perform due to obstacles on the quay.
  • apparatus for providing power or/and other utility from shore to a floating vessel as set out in claim 1 of the claims appended hereto.
  • apparatus for providing power or/and other utility from shore to a floating vessel through at least one flexible elongate member as set out in claim 23 of the claims appended hereto.
  • One major objective is to manage one or more flexible electric cables, from shore to and from a floating vessel.
  • Some embodiments can be designed for feeding electric power through mentioned flexible cables, from an onshore power grid, to the vessels, without taking up any valuable quay space, improving greatly existing reel and tower-based cable feed solutions, on the market today.
  • Some embodiments can be designed to achieve a better, no space demanding front- end shore power distribution system.
  • Another major objective is to feed power to the vessels without any power derating, as the cables are not spooled onto a reel. This can provide a clear advantage compared to a reel- based system that has a significant heat derating and resulting power loss.
  • Some embodiments can include using a tube/well system can be applied from 0-90 degrees on the water line, as the local conditions in the port, fjord or open harbour dictates. For example, it can be built below, or into quay structures, or in some cases mounted on top of the quay deck. Some embodiments can include using an internal electric powered cable injector system, and a corresponding electric powered cable“zip-lock” system for a controlled feeding sequence of cable, in and out of the tube/well, and for securing the cable in a tailor made ducting system, during cable storage situations.
  • Some embodiments can be electrically operated and have internal control and power drive system, that will operate the cable in and out, and store the cables automatically, with very little or no service demand. All based on existing proven and secure industrial servo drive control solutions
  • Some embodiments of invention are distinguished from existing reel or tower-based systems with a unique and totally different design. It will require no deck space on the quay. Only a quay hatch will be visible, where the cables come out from below the quay structure, in desired cable lengths. No obstacles for trucks and cranes, carrying goods, as all quay space will be intact for regular port logistics.
  • Some embodiments of the invention can also be used as an anchored floating version.
  • anchored in the open sea in open water in a harbour, or in a fjord. Attached to a floating raft or just a floating power buoy, so a vessel can attach to floating shore power, while at anchor in a fjord, or just waiting for mooring and slot time in a busy harbour.
  • a primary objective is to provide a system for feeding electric power through mentioned flexible cables, from an onshore power grid, to the vessels, without taking up any valuable quay space.
  • Another primary objective is to provide a solution intended for this shore power market. It is designed to store and administrate on or more flexible electric cables, from shore, to and from floating vessels. Vessels moored in the harbour, free floating, or at anchor in the sea. This multiple power cable feed device is unique among existing cable management systems known in the market.
  • Another primary objective is to provide a, cable feed system below or integrated in the quay, submerged or partly submerged, that store and manage the cable lengths inside a cable tube, or cable well.
  • One or more cables can be applied in the tube, as dictated by the harbour application power demand, based again on the vessel(s) power demand.
  • Another primary objective is to provide a sea water tight unit, that can withstand outside water pressure, provided the other open-end reach above the water line. This make the design very flexible, and an ideal solution for shore power feed to free floating cruise vessels in fjords.
  • Another primary objective is to provide a tube/well that has an open duct, where the cable(s) goes in and out of the tube/well.
  • An opening that can be run through the quay deck and be secured in the quay deck through a bolted flange.
  • This flange can be applied with a top hatch, to cap and secure the device from unintended incidents, and act as a weather seal.
  • Embodiments of the invention segregates itself from existing reel or tower-based systems with a unique design, that will require no deck space on the quay. Only a quay hatch may be sufficient, where the cables can come out from below the quay, in desired lengths. No obstacles for trucks and cranes, carrying goods, as all quay space will be intact for regular port logistics.
  • the apparatus will not appear on the quay, and can be built below, or into quay structures and the cable duct system will be hidden away, and has a tube/well that has an open end, where the cable(s) go in and out of the tube/well, and an opening that can be run through the quay deck and be secured in the quay deck through a bolted flange.
