An intervention system and method for control of seabed equipment, including a control umbilical connected to a support vessel or rig via a surface winch; a tether connected to underwater seabed equipment; and an umbilical management system unit coupled between the tether and the control umbilical to couple the support vessel or rig to the seabed equipment. The control umbilical and the tether via the umbilical management system unit provide a communications channel for communicating media, including data, electrical power, hydraulic power and/or chemical treatment fluid, from the support vessel or rig to the seabed equipment. The umbilical management system unit allows for easy deployment and management of the control umbilical and tether and can reel in or pay out the tether and/or the control umbilical under remote control or autonomously.

The system of claim 9, wherein the system is configured to adjust a horizontal position of the umbilical management system unit using one or more thrusters provided in the umbilical management system unit. 14. The system of claim 9, wherein the system is configured to adjust a vertical position of the umbilical management system unit using a winch provided in at least one of the umbilical management system unit and the support vessel or rig. 15. The system of claim 1, further comprising a hose drum or reel provided on the umbilical management system unit for reeling in or paying out a fluid top-up line connected to the control umbilical for chemical injection or topping up of fluids. 16. The system of claim 15, wherein the hose drum or reel includes a constant tension capability provided by a spooler arm, and the hose drum or reel and the spooler arm are operated by a power system of the umbilical management system unit. 17. The system of claim 15, wherein a hot stab connection is provided for detaching the fluid top-up line from the hose drum or reel of the umbilical management system unit, and an exit chute is provided on the hose drum or reel for the fluid top-up line, with the fluid top-up line having another hot stab connection on the exit chute end. 18. The system of claim 1, further comprising a fluid top-up line connected to the control umbilical for chemical injection or topping up of fluids, with upper and lower floats provided on the fluid top-up line for providing tension and/or heave compensation, and with a sheave or roller device mounted on the umbilical management system unit for accommodating the fluid top-up line. 19. The system of claim 1, further comprising: a fluid line connectable with the control umbilical between the support vessel or rig and the seabed equipment for communicating at least one of hydraulic power and chemical treatment fluid from the support vessel or rig to the seabed equipment. 20. The system of claim 1, wherein the control umbilical and the tether via the umbilical management system unit provide the communications channel for communicating electrical power from the support vessel or rig to the seabed equipment for controlling the seabed equipment. 21. An intervention method for control of seabed equipment from a support vessel or rig, the method comprising: connecting a control umbilical to the support vessel or rig;connecting a tether to seabed equipment located underwater;coupling an umbilical management system unit between the tether and the control umbilical;coupling with the umbilical management system unit the control umbilical via the tether to the underwater seabed equipment, thereby coupling the support vessel or rig to the seabed equipment;providing via the control umbilical, the tether, and the umbilical management system unit a communications channel for communicating data and power from the support vessel or rig to the seabed equipment;controlling a distance between the umbilical management system unit and the seabed equipment with the underwater seabed equipment through the control umbilical and the tether; andcontrolling the seabed equipment from the support vessel or rig via communications through the control umbilical and the tether. 22.
