Definitions

  • the present invention relates to a vessel for cleaning the ocean from pollution such as oil, plastic waste or the like and a method for collecting pollution from the ocean.
  • the plastic waste in the oceans is typically continuously crushed or degraded into smaller particles by wave motion, with a large amount of these smaller particles being in the range of 3-6 mm in diameter and hereafter being eaten by sea animals such as fish which confuses the plastic waste with food.
  • W02006061453 An example of ocean cleaning vessels is disclosed in W02006061453, which is incor- porated in the present disclosure by reference.
  • the reference describes a vessel and method for the specific purpose of collecting oil from water, by passing the oil on the water surface into a large space within the vessel, where the wave surge is damped enough to allow the oil on the water surface to be effectively collected. Inside the large space, a device for collecting oil from the surface of water is disposed.
  • the vessel de- scribed in W02006061453 is used for the cleaning purpose only and only removes the oil which flows into the larger space within the hull.
  • WO2012123873 describes a vessel for removing petroleum from the water surface.
  • the vessel comprises a large guide system disposed alongside the hull of the ship and at approx the entire length of the hull.
  • the guide is kept at the water surface, and together with the hull creates a guiding channel alongside the hull and towards a conveying surface for removing the petroleum from the water.
  • the entire system described in WO2012123873 is bulky and is not suitable for being stored inside the hull of the ship in a retracted position.
  • the vessel described is not suitable for travelling long distances and to be used for different purposes than water cleaning.
  • a vessel for cleaning the ocean from waste material comprising:
  • a hull extending between a bow and stern, and defining a port side and a star- board side
  • a conveyor assembly having a first conveyer for conveying said waste material from said ocean onto said vessel
  • said waste collecting system being outside said hull when said waste collecting system being in said extended state during cleaning of said ocean from waste mate- rial.
  • the waste collecting system When the waste collecting system is in a retracted state, the waste collecting system is placed inside the hull, meaning the waste collecting system being placed between the portside and the starboard side of the ship. In the retracted state, the waste collecting system can thus be positioned above a plane of the surface deck or below a plane of the surface deck.
  • the optimal speed of the vessel for cleaning the ocean surface is approxi- mate 2,5-5 knots.
  • the speed could be less or higher, however, at lower speeds the covered area gets smaller, and at higher speeds the forces of the water towards the waste collecting system gets higher and increases the fuel consumption of the vessel.
  • the width of the waste collecting system preferably ranges from 1-4 meters, however, the width may alternative range between 0.5-1 meters or from 4-6 meters. In a preferred embodiment the waste collecting system has a width of 3 meters.
  • the total covered width is equal to the breadth of the ship and the width of the two waste collecting systems.
  • the total covered width is 26 meters which results in a cleaned area of approx. 0,2 km 2 each sailing hour.
  • the waste material being collected is stored inside the hull in large storage tanks. At docking, the storage tanks can be lifted out of the vessel and emptied or in an alternative embodiment, the waste material may be conveyed out of the vessel with a suitable con- veyer.
  • the first conveyor having a water end, and a pulley end opposite the water end.
  • the pulley end has a pulley drive system powered by a motor for driving the conveyer.
  • the motor may be pneumatic, electric, hydraulic or manual.
  • the water end of the first con- veyor being below the waterline when the waste collecting system being in the ex tended state.
  • the conveyer conveys at a specific speed specified in relation to the travelling speed and/or the amount of waste material. If the amount of waste material encountering the conveyer increases, the conveying speed increases like- wise.
  • the first conveyor includes a belt having holes for passing water through the holes and for filtering the waste material from the ocean.
  • the conveyer has a belt conveyer having a width slightly smaller that the width of the waste collecting system enabling the conveyer to be supported inside the conveyer frame.
  • the belt is having a number of holes for filtering the waste material and for passing water through the holes. It is understood that the holes can have a va- riety of configurations; the amount of holes and the size of the holes suitable for differ- ent types or sizes of waste material.
  • the belt of the conveyer may be in- terchanged with another belt having a different configuration suitable for a different type or size of waste.
  • the belt may be manufactured from any suitable material such
  • 158748/BJ/JS/MT - Filing date 10 April 2019 as a large rubber band having holes, or as a woven mesh-like band woven from any suitable material e.g. nylon.
  • the waste collecting system may comprise different types of sensors, e.g. for sensing the amount of waste encountering the conveyer or any encountering of sea animals such as fish.
  • the vessel comprising a sea- water channel for leading seawater through the vessel, the hull having a first opening constituting an inlet into the seawater channel, and a second opening constituting an outlet from the seawater channel.

  • the conveyor assembly compris- ing a trawl and a winch, said trawl being attached to said winch for winching said trawl in and out of said ocean.
  • the trawl is a net similar to trawl nets used for fishing and is being dragged by the ves- sel for collecting waste material.
  • the trawl is a cone-shaped net having a“mouth” end and a closed“tail” end, where a vertical opening of the“mouth” end of the trawl is cre- ated by using flotation on an upper edge ("floatline”) and a weight on the lower edge of the net“mouth”.
