Conventional Tree System Dual Bore/WITS

36 Core Workover Control System

I.D. NO. 9801

Conventional Tree System Dual Bore/WITS The workover control system consists of:

Hydraulic power unit - 9801-1
Workover control panel - 9801-2
10 core umbilical annulus umbilical - 9801-3
36 core workover umbilical c/w 1 electric line - 9801-4

The hydraulic power unit/workover control panel is self-contained inside a transportable container. The workover reeler is of an open frame cabinet design, housing the umbilical.

The annulus reeler is of an open frame design, housing the umbilical. A transportation basket is provided to allow storage of jumper hoses, control panels, sheaves, etc.

Hydraulic Power Unit Workover Control Panel

I.D. NO. 9801-1

��

The hydraulic power unit generates hydraulic pressure at 3 different levels for supply to the workover control panel.
Each supply header has a flow meter/totalizer fitted.
The workover control panel supplies pressure via manual control valves to control of all the functions associated with the Workover, and provide common ESD headers as required.
The unit has a total of 36 functions with 6 functions for double acting valves or lock/unlock functions.
The layout is a pigeon hole arrangement, labeled 1 to 36.
Mimic plates are mounted adjacent to the control valves with different functions and labeled accordingly with the valve function number.
The unit is containerized, with all controls being performed inside the unit.
The workover control panel is fitted with a male multi-way stab plate for connection to the workover reeler via a jumper umbilical.
Connection to all other supply/return jumpers is via quick disconnect couplings (male half fitted to the panel).
The HPU/workover control panel is supplied with certified lifting equipment.
