A Typical Interconnection System

Figure 3 shows a typical power-cabling system. An umbilical cable is terminated to a SUTA (subsea umbilical termina- tion assembly), which is roughly equiv- alent to the wall socket in your home.

From the SUTA, electrical fl ying leads (EFLs) bring power to the pump or other modules. To continue the home analogy,

EFLs are like extension cords. A sec- ondary jumper harness ensures connec- tion from the EFL to the penetrator that serves as a transition at the pressurized motor enclosure.

Wet-mate connectors are highly engi- neered devices suitable for harsh marine environments. They are a key element of subsea equipment used in the subsea fac- tory processing for oil & gas extraction.

Wet-mate connectors provide a means of communications between the control room and the subsea equipment. They enable information retrieval from the sensors located in the well and related subsea equipment to assess the integrity of the well and related equipment opti- mizing reservoir production. They are more complex than standard electrical connectors because of the need to pro- vide a sealed interface that can be main- tained at subsea water pressures, carry high voltages and currents, and deliver very long operating lives. Products such as TE’s DEUTSCH line of subsea wet- mate connectors and penetrators are the result of years of offshore experience, both topside and undersea. Our prod- uct development advantage includes a close working relationship with design- ers and users of deepwater equipment to best match the connector to applica- tion needs, providing for subsea power distribution and subsea processing in a safe, reliable and economical manner.
