摘要： This device comprises a pipe formed of separate flexible pipe sections which in use are supported by buoyant elements maintained immersed by anchoring means. The flexible pipe sections are interconnected by couplings with at least some of these couplings being connected to a buoyant element and comprising stress limiters applied to the pipe sections adjacent said couplings.

摘要： The equipment is connected through a line to an auxiliary buoyant element to form an assembly of positive buoyancy, the equipment to be submerged and the auxiliary element being at first held in spaced relationship. The equipment is thereafter dropped into water, the length of the connecting line being so limited that the equipment then becomes suspended in water under the auxiliary element without reaching the water bottom. The location of the assembly is then optionally adjusted, and its buoyancy is reduced to a negative value.

摘要： An underwater electric connector includes two elements (1,9) which may be coupled end to end and which are each equipped with a cylindrical cavity and a set of contact pieces (17, 20). One of the elements (1) is equipped with a device for injecting an insulating fluid under pressure. Housings (2,8) of the elements have end pieces (11,10) which may be fitted one onto the other. Each set of contact pieces is secured on the element (1,9) which carries it. A cylindrical pin (22) bears two groups (24,25) of contact pieces connected electrically by twos from one group (24) to the other (25), and is equipped with a head (26,23) which seals the cylindrical cavity (19) of the second element (9) when the pin is completely inserted. Devices for gripping (27) and displacement (28) are provided in the first element to secure the pin in the position at which its contacts (24,25) are opposite the contact pieces of the two sets (17,20) of contacts.
