Definitions

  • the invention relates to a pier module according to the preamble of claim 1.
  • the invention also relates to a method of anchoring a pier module.
  • Conventional piers are typically assembled from large pier sections which require an installation barge and/or a floating lifting platform for moving the pier sections to desired locations. Therefore, it is difficult to assemble the pier and modify the pier configuration, for example the size of the pier and/or location of the pier sections. Further, the transportation of large pier sections to the marina area is difficult and costly.
  • Anchoring of the pier is also costly and time-consuming. Typically, about half of the installation costs of the pier are related to the anchoring.
  • the object of the present invention is to reduce the above-mentioned drawbacks.
  • the object of the invention can be achieved by a pier module according to claim 1 and a method according to claim 12.
  • the pier module comprises a frame and at least one ballast tank attached to the frame.
  • the pier module further comprises at least one anchor and the frame includes an anchor space for each anchor, and anchor is removably arranged in said anchor space.
  • the anchor (s) of the pier module are arranged in the anchor space(s) within the frame of the pier module and held in the anchor space(s).
  • the pier module with the integrated anchor(s) can be stored and transferred to the installation place of the pier module as a single unit.
  • the anchors are removed from the anchor spaces and lowered to the bottom of the waterway.
  • the anchor(s) are lifted from the bottom of the waterway into the anchor space(s) inside the frame. Thereafter, the pier module with the anchors can be moved as a single unit. This makes it easier and faster to transport and install the pier module.
  • the anchors are arranged in the anchor spaces of the pier module during the transport and installation of the module, it is not necessary to use separate anchors that must be installed with an installation barge or similar. This significantly reduces the transport and installation costs of the pier module and the pier.
  • Figs. 1 to 6 show a floating pier module 1 according to an embodiment of the invention.
  • the pier module 1 can be used as a mooring and/or a storage platform for boats 19.
  • the pier module 1 comprises a frame 2 and at least one ballast volume, such as ballast tank 3, attached to the frame 2.
  • the pier module 1 comprises three or more, for example 3 to 6 ballast tanks 3.
  • the pier module 1 comprises four ballast tanks 3.
  • the ballast tanks 3 are arranged one after the other in a longitudinal direction of the frame 2 and/or the pier module 1.
  • the ballast tanks 3 extend over the entire width of the frame 2.
  • the ballast tanks 3 are placed inside the frame 2.
  • the ballast tanks 3 can have a circular or rectangular cross-sectional shape.
  • the frame 2 comprises a lower frame part 2.1 and an upper frame part 2.2.
  • the lower and upper frame parts are rectangular.
  • the lower frame part 2.1 and the upper frame part 2.2 are arranged one on top of the other.
  • the lower frame part 2.1 and the upper frame part 2.2 are arranged at a distance from each other in the vertical direction.
  • the frame 2 further comprises connecting posts 2.3 that connect the lower frame part 2.1 and the upper frame part 2.2 to each other.
  • the connecting posts 2.3 are vertical.
  • the connecting posts 2.3 are located at least at the corners of the frame parts 2.1; 2.2.
  • the ballast tanks 3 are located within the frame 2 between the frame parts 2.1, 2.2.
  • the length and the width of the frame 2 and/or pier module 1 are equal to or less than those of the 20 feet standard container (length 6.1 m, width 2.44 m) or 40 feet standard container (length 12.2 m, width 2.44 m).
  • the frame 2/pier module 1 can be transported and/or stored as a container-type structure. Two or more frames 2/pier modules 1 can be placed on top of the other during the transport and storage to form a standard container-type structure. This enables efficient and cost-effective transportation of the pier modules 1.
  • End ballast tanks 3 nearest to the ends of the pier module 1 adjust the tilt angle of the pier module 1, i.e. the tilt angle with respect to water surface.
  • Middle ballast tank(s) 3 in the middle, i.e. between the end ballast tanks 3, adjust the buoyancy of the pier module 1.
  • the ballast tanks 3 may be internally divided into sections to increase their stability.
  • the ballast tanks 3 can be fluidly disconnected from each other so that liquid cannot flow therebetween.
  • the pier module 1 comprises a deck 4 located above the ballast tanks 3.
  • the deck 4 is attached to the frame 2.
  • the deck 4 is provided with keel rollers 5 for supporting a hull of the boat 19 as the boat 19 is on the deck 4 and/or when the boat 19 is lifted and pulled onto pier module 1 and lowered from the pier module 1 into the water.
  • the deck 4 comprises a lower deck 4.1 and an upper deck 4.2.
  • the lower deck 4.1 is located above the ballast tanks 3 and the upper deck 4.2 at a distance from the lower deck 4.1 in the vertical direction.
  • the pier module 1 comprises a storage space located between the lower deck 4.1 and the upper deck 4.2.
  • the upper deck 4.2 is hingedly attached to the frame 2. Thus, the upper deck 4.2 can be turned to an upright position in which it provides shelter for the boat 19 placed on the pier module 1.
  • the lower deck 4.1 is provided with the keel rollers 5.
  • the pier module 1 is also provided with a winch 6 for pulling/lifting the boat 19 onto the pier module 1, i.e. onto the deck 4.
  • the winch 6 is installed at a dry end of the pier module 1.
  • the dry end of the pier module 1 is the end that is intended to be connected to another pier part, e.g. to another pier module or to a fixed pier structure.
  • the dry end of the pier module 1 is pivotally connected to said pier part.
  • the opposite end of the pier module 1 is the free end.
