ABSTRACT:
The present invention refers to a process to permit descent to sea bottom, with the use of two conventional tug boats, of equipment used in submarine field oil field exploration, especially descent of equipment of large size and mass in deep water fields.Equipment is being suspended by a sling, attached to an auxiliary component. This, on its turn, is attached to two cables, each one activated by one of the two tug boats. Connection of the auxiliary component to cables is being made by means of connectors, which are trespassed thru cable openings and attached to auxiliary component by screws, forming a connection, in which connectors may carry out a pivotal movement around holes of auxiliary component. This movement of said connectors almost entirely absorbs oscillations of tug boats caused by waves, without transmitting same to equipment. In this way, both tug boats may lower equipment and cross the so-called resonance area without risk of its occurrence.
