AI Technical Summary

Technical Problem

Existing mooring systems for seaweed cultivation are inefficient due to the time-consuming and costly process of connecting and disconnecting cultivation beds from the mooring arrangement, which requires submerging the beds and dealing with buoyancy issues.

Method used

A mooring arrangement featuring a plurality of anchors, buoys, taut-lines, anchor-lines, and a frame-line, configured to create a main frame that can be adjusted between growth and maintenance depths, allowing for easy access and efficient connection/disconnection of cultivation structures.

Benefits of technology

The mooring arrangement enables efficient and cost-effective cultivation and harvesting of seaweed by allowing for dynamic depth adjustment, reducing the complexity and cost of connecting/disconnecting cultivation structures, and improving access for maintenance.

Abstract

A mooring arrangement (2) for mooring a cultivation structure (8), the mooring arrangement comprising a cultivation structure connection (46) configured for connecting the cultivation structure (8) to the mooring arrangement (2), wherein: - the mooring arrangement (2) comprises a plurality of anchors (3), a plurality of buoys (22), a plurality of taut-lines (24), a plurality of anchor-lines (32), and a frame-line (42); - the mooring arrangement (2) is configured such that the frame-line (42) creates a main frame (4) comprising a repetitive pattern (44); - the taut-lines (24) are configured to provide a connection between each buoy (22) and the main frame (4); - the anchor-lines (32) are configured to provide a connection between each anchor (3) and the main frame (4); and - the buoy (22) comprises a taut-line retention system (28) configured to adapt a taut-line length, wherein the taut-line length is a length between the buoy (22) and the main frame (4) It is also disclosed a cultivation structure (8) for cultivating low trophic organisms, the cultivation structure (8) is disconnectable from the mooring arrangement (2), wherein: - the cultivation structure (8) comprises a lower member (82), an upper member (84) and a substrate line (86); and - the cultivation structure (8) is formed such that a plurality of substrate lines (86) connect the upper member (84) and the lower member (82).
