Abstract: A marine survey system includes a collar configured to be affixed to a tow member, to connect a separation member to the tow member and to release the separation member when a lock-release condition is met. Alternatively or additionally, the marine survey system includes a variable drag force mechanism configured to generate a first drag force pushing the collar downstream before the collar reaches a downstream element beyond which the collar cannot move, and to generate a second drag force after the collar has reached the downstream element.

Abstract translation: 海洋测量系统包括被构造成固定到丝束构件上的套环，以将分离构件连接到丝束构件上，并且当满足锁定释放条件时释放分离构件。 或者或另外，海洋测量系统包括可变牵引力机构，其构造成在套环到达下游元件之前产生推动套环下游的第一牵引力，超过该下游元件，套环不能移动，并且在套环具有 到达下游元素。

Abstract: A cable-protecting device is used on a cable of a marine survey system to oppose cable bending and/or to limit a bending radius of the cable. The cable-protecting device has a functional body made of at least two portions configured to be clamped together to surround the cable, a gripping system configured to oppose the functional body sliding along the cable, and a closing system configured enable the at least two portions to engage fast and remain clamped.
