Is there an example of the Intervention Workover Control Systems (IWOCS) configuration that someone can share?

IWOCS are complex and varied from one company to another. I would recommend to contact a specific manufacturer and ask them to propose an IWOCS configuration based on your requirements and project’s needs.
You can use the following conditions and requirements when specifying the IWOCS:
The control system is composed of all the equipment necessary to control the subsea test tree, the Tubing Hanger Running Tool (THRT) / Cap Tree Running Tool (CTRT), the lubricator valve, and the surface tree. The components of the control system include, but are not limited to, the following:
Umbilical clamps preferably are to be cast or forged steel, and must have no loose components. All bolting or fastening devices used by the clamps are to be trapped in place, preventing accidental dropping of sub-components in the hole.
A separate control system should be used for the subsea tree, utilizing separate multi-hose umbilical(s) attached along the outside of the marine riser. To avoid confusion, the umbilical used inside the marine riser to control the SSTT is to be called the "internal IWOCS umbilical" and the umbilical on the outside of the riser is to be called the "external IWOCS umbilical.”
