Abstract
An offshore farming system comprising an elongated vertical support column floating vertically in water with a larger extension below sea surface than above the sea surface, and a rigid cage structure enclosing the elongated vertical support column in circumferential direction and arranged movable in longitudinal direction of the elongated vertical support column.
Claims19
An offshore farming system comprising:
- an elongated vertical support column arranged to float vertically in water and defining a longitudinal direction, the support column being configured to have a longer extension portion extending below a sea surface and a shorter extension portion extending above the sea surface;
- a rigid cage structure circumferentially surrounding the elongated vertical support column, the rigid cage structure being configured to move in the longitudinal direction relative to the support column;
- said rigid cage structure including an attachment assembly having an inner volume and formed by an upper inner cage ring, a lower inner cage ring, and vertical beams or rods extending between and attached to a respective circumference of the upper inner cage ring and the lower inner cage ring;
- and
- a controllable moving device configured to move the rigid cage structure,
- wherein the longer extension portion of the elongated vertical support column is configured to allow the rigid cage structure to move in the longitudinal direction so as to be submerged at a position either:
- below affection of waves at a location of the offshore farming system;
- or
- below an area where lice and similar organisms live that affect farmed marine species;
- and
- wherein the rigid cage structure comprises a controllable ballast and is controllably movable in the longitudinal direction of the elongated vertical support column, said controllable ballast being provided by taking in and removing water from the inner volume of the attachment assembly.

- a rigid cage structure circumferentially surrounding the elongated vertical support column, the rigid cage structure comprising hollow tubular members and being configured to move in the longitudinal direction relative to the support column;
- said hollow tubular members comprising an upper inner cage ring, an upper outer cage ring, a lower inner cage ring, a lower outer cage ring, and vertical beams or rods extending between and attached to the upper inner cage ring and the lower inner cage ring as well as between the upper outer cage ring and the lower outer cage ring;
- and
- a controllable ballast system that supplies power to the elongated vertical support column, air to the hollow tubular members of the rigid cage structure and being configured to take in and remove water from the hollow tubular members;
- and
- a winch device located on or inside the elongated vertical support column and being configured to function with the controllable ballast system to raise and lower the rigid cage structure relative to the elongated vertical support column.
