Definitions

  • the invention relates to a Mobile Electromagnetic Mooring System for small watercraft, consisting of a set of at least two electromagnetic grippers, powered by floating power supply buoys, connected by mooring lines to a set of at least two mooring winches located on the bow and stern of the ship, respectively, ensuring controlled constant tension on the mooring lines and allowing for the free movement of an intervention/service vessel moored to a larger vessel along its side.
  • the Mobile Electromagnetic Mooring System controlled by the intervention/service unit system is designed to fit a small intervention/service vessel that moors to the sides of larger vessels requiring intervention for repair, servicing, or the transfer of cargo or people, without the need to involve a large number of crew members during mooring operations.
  • Every type of ship must have appropriate mooring systems that, following the shutdown of its propulsion at the end of a voyage, allow it to be moored in order not to be exposed to the dangers associated with the negative influence of external factors, i.e., wind, water currents, and waves.
  • Mooring systems secure the ship at the quay, its fixed and/or movable jetty, terminal, or loading berth in the port, or in the case of another ship, another fixed, mobile, or loading installation located on the shore, in an offshore sector, or a water basin, as in the solution according to the invention.
  • mooring two ships of different and/or similar dimensions for transhipment and/or service always requires special techniques and extreme caution to ultimately avoid damage to the units throughout the approach or breakage of the lines due to excessive loads during their securing.
  • Such mooring can be done in three ways: (a) in port, using the so-called double berth, where one of the ships is already berthed to the quay and the other is moored to its outer side on the side opposite from the quay, (b) at anchorage, when one of the ships is at anchor and the other is approaching and mooring to the ship already anchored, (c) when mooring operations are being carried out when both ships are in motion in the water and/or over the ground (drifting).
  • the mooring arrangement depends on the size of the ships involved in the planned mooring operations.
  • a manoeuvring vessel shall approach a vessel at anchor or when drifting and maintain a steady course with the smallest possible approach angle.
  • the approach area is normally behind the traverse of the vessel approached by the manoeuvring unit.
  • the manoeuvring vessel steers a course parallel to that of the other vessel and reduces the horizontal distance between the vessels.
  • the manoeuvring vessel uses the motions of the engine and rudder to reduce the distance smoothly and with the lowest possible speed, until the fenders located on their sides come into contact.
  • the two ships connect in parallel and the ropes pass according to the mooring plan. It is a very difficult and demanding operation for both the person manoeuvring the vessel and the crews of each unit responsible for the quick and safe mooring of such ships.
  • the currently proposed mooring systems in particular with regard to small intervention, diving, service and cargo or people transfer units where it is also crucial to perform underwater repair works, pose many problems, including: (a) they increase the risk of the mooring breaking or sliding off, which may result in serious injury or death to crew members; (b) they cause a high angle of the mooring lines directed upwards to the main deck of the serviced mothership with high freeboard, which has a significant impact on the level of stresses and breaking forces (loads) generated there, and in combination with unfavourable hydrometeorological conditions (e.g.
  • Patent description PL232697 describes a known device for mooring a watercraft, which is a fender with a front panel containing at least one electromagnetic module connected to the electric power supply of this module, the front panel having elements for fixing the panel to the berth which include shock-absorbers.
  • This device is both a mooring device and a fender.
  • the description of the utility model Ru.59099 details a floating object mooring device in the form of a pivoting arm, consisting of a catch and a cooperating mooring cylinder to which the piston rod is attached.
  • the solution enables quick and reliable fixing of the mooring vessel relative to the quay. These are large-size port facilities and cannot be used in ship-to-ship operations.
  • the Mobile Electromagnetic Mooring System solution tackles the problems and requirements of small intervention/service watercraft, including work dive boats, during mooring to a larger serviced unit.
  • the Mobile Electromagnetic Mooring System allows the intervention/service vessel to move freely along the serviced unit, which eliminates the risks associated with the possibility of breaking the mooring lines and minimizes crew interference involved in the mooring process and/or mutual movement of these ships, which in turn has a very positive effect on the general safety and speed of mooring operations carried out on the side (mooring and unberthing).
  • the essence of the invention is a Mobile Electromagnetic Mooring System mounted in the overwater zone located above the waterline of the small intervention/service vessel, equipped on the approach side with mobile pneumatic distance fenders, and at least two mooring winches located at each end of the intervention vessel, mounted with a system of constant tension mooring ropes, the ends of which are attached to floating power supply buoys via insulated power cables with mooring ropes positioned horizontally in electromagnetic grippers, controlled from the central control panel of the intervention/service vessel,
  • each set of at least two electromagnetic grippers is provided with an electromagnet powered by at least two floating power supply buoys, all single electromagnetic grippers being powered by a single floating power supply buoy using an insulated power cable.
  • each of the electromagnetic grippers is provided with an emergency electromagnetic release for activation in the central control panel of the intervention/service vessel.
  • each mooring winch is equipped with an integrated system to measure and maintain constant tension on each mooring line connected to the floating power supply buoy through a common control panel located with the emergency electromagnetic release in the central control panel of the intervention/service vessel,
  • each floating power supply buoy is equipped with a photovoltaic panel-assisted power supply to allow operation for at least 10 hours.
  • the power supply is a battery or a power source supplied by an intervention/service or serviced unit.
  • the Mobile Electromagnetic Mooring System is intended to equip a small surface intervention unit mooring to the side of larger vessels to carry out servicing, repairs, or the transfer of cargo or people.
  • the main advantages of the presented solution are the reduction of the probability of an accident related to operations on the mooring lines by reducing the "high viewing angles" and the breakage of the mooring lines.
  • the mooring lines look up to the ship's main deck, usually with a very high freeboard.
  • the mooring lines look horizontal and are attached to the mobile electromagnetic grippers attached to the hull of the intervention vessel.
  • An additional advantage of the system according to the invention is the short time of mooring and unberthing operations, as well as the unnecessity of the crew of a damaged/serviced ship to interfere with mooring operations.
  • the valuable importance is the movement of the intervention unit along the side of a larger vessel to carry out the necessary work without the interference of the crew of the serviced vessel and to improve the safety of the underwater diver.
  • the central control panel of the Mobile Electromagnetic Mooring System guarantees quick disconnection of the electromagnetic grippers with floating power supply buoys, and the use of conventional mooring winches ensures the mobility of the system.
  • the solution according to the invention allows the intervention unit to be attached to a larger ship with a steel hull, even if it is contaminated, which in standard conditions makes such operations difficult.
