A submersible pen system

A submersible pen system for aquaculture, comprising:

• a collar circumferentially arranged around a hub, at least one of the hub and the collar having a variable buoyancy;
• at least one net panel having a first end and a second end and surfaces at least partially defining a pen having a containment volume;
• the first end of the at least one net panel being coupled to the collar;
• at least one tensioning element being coupled to a second end of the at least one net panel;
• and
• a stabilising diaphragm being coupled between each of the hub and the collar and being at least partially deformable, the stabilising diaphragm comprising at least one elastic tendon and being configured to operatively provide a stabilising force between the hub and the collar such that a deformation of the stabilising diaphragm effects a degree of movement in the collar with respect to the hub when exposed to external dynamic loading.

• and
• an anchor (A), the anchor (A) being separate to, and operatively mate-able with, the hub.

A submersible pen system for aquaculture in a column of water, comprising:

• a collar circumferentially arranged around a hub, at least one of the hub and the collar having a variable buoyancy which is controllable to adjust a vertical position of the collar in the column of water;
• at least one net panel having a first end and a second end and surfaces at least partially defining a pen having a containment volume;
• the first end of the at least one net panel being coupled to the collar;
• at least one tensioning element being coupled to a second end of the at least one net panel;
• and
• a stabilising diaphragm being coupled between each of the hub and the collar and being at least partially deformable, the stabilising diaphragm being configured to operatively provide a stabilising force between the hub and the collar such that a deformation of the stabilising diaphragm effects a degree of movement in the collar with respect to the hub when exposed to external dynamic loading;
