MODULAR SUBSEA DISTRIBUTION UNITS

The SDU (Subsea Distribution Unit) is located subsea and provides the hydraulic, chemical, fiber optic and electrical distribution between the SUTA (Subsea Umbilical Termination Assembly) and the rest of the subsea system. The SDU distributes the hydraulic, chemical, fiber optic and electrical supplies to the flying leads which in turn connect to the subsea trees and subsea manifolds. The SDU is mounted onto a special mounting base which in turn is installed onto a subsea foundation such as a mudmat.
