Title:
UNDERWATER TOWING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/248740
Kind Code:
A1
Abstract:
An underwater towing system (1) according to an embodiment comprises: a pulling machine (2) that travels on or in water; a towing rope (3) that hangs down into water from the pulling machine (2); and a plurality of underwater work machines (5) that are pulled by the towing rope (3). At least one light emitting device (4) is attached to the towing rope (3). The light emitting device (4) is controlled by a control device (21) which is included in the pulling machine (2). Each of the underwater work machines (5) includes a light reception device (53) capable of receiving an optical signal from the light emitting device (4). The control device (21) causes the light emitting device (4) to emit a separation signal for the underwater work machine (5). The underwater work machine (5) separates from the towing rope (3) when the separation signal is received by the light reception device (53).
