Abstract: A mooring chain stopping device including a locking housing with a channel inside which a mooring chain slides, and including a connection to a buoyant structure to direct the channel axis to the pulling axis of the chain, the housing having bolts inhibiting sliding of the chain in the channel and a device for measuring tension in the chain built into the locking housing. The measuring device includes a chamber including a defonnable shell, and filled with a liquid; a bearing part movably mounted in the locking housing, the bearing placed between the bolts and the chamber, and engaging the shell wall to pressurize the liquid, the bearing arranged so the forces exerted by said mooring chain on the bolts cause the movement of the bearing part and the pressurization of said chamber; and at least one pressure sensor to measure the pressure of the liquid.

Abstract: The invention relates to a mooring chain stopping device, comprising: a locking housing (50) provided with a channel (53) inside which a mooring chain (2) is capable of sliding, said housing including a means for connecting to a buoyant structure (1), which is configured to direct the axis of said channel to the pulling axis (A) of said chain, said housing further having built-in bolts (2) that are configured to inhibit the sliding of said chain in said channel; and a means for measuring the tension in said mooring chain, said measuring means being built into said locking housing, characterized in that said measuring means includes: at least one chamber (6) consisting of a deformable, closed shell, said chamber being filled with a liquid; at least one bearing part (7) movably mounted in the locking housing (50), said bearing part being placed between the bolts (52) and the chamber (6), said bearing part engaging with the wall of the shell of said chamber so as to pressurize the liquid contained therein, said
