The IWOCS Pneumatic Umbilical Winch is a robust, self-contained unit designed for subsea control operations in harsh offshore environments. It delivers control fluids, chemicals, and power to subsea trees for valve operation and monitoring. Key features include a pneumatic drive, automatic level-wind, and dual failsafe braking, offering reliable performance for demanding energy applications.
We are pleased to showcase our advanced IWOCS (Interface Winch for Operating Subsea Systems) Umbilical Winch, a robust and reliable solution designed for critical subsea intervention tasks on both offshore platforms and land-based operations.
This winch system is manufactured to meet stringent industrial standards for performance and safety in corrosive marine environments. It is engineered to transport water-based control fluids, chemicals, and electrical power to subsea Christmas trees, enabling essential functions such as valve operation, pressure testing, chemical injection, and remote system monitoring.
Key Features & Technical Specifications:
- Drive System: Powered by a reliable pneumatic motor for smooth, infinitely variable speed control and safe operation in hazardous areas.
- Automatic Level-Wind: Ensures clean, even, and damage-free spooling of the umbilical during deployment and retrieval.
- Integrated Safety Braking: Features a failsafe, closed-loop pneumatic braking system with dual brakes on both the motor and drum, supplemented by a mechanical lock-pin for secure parking.
- Drum Interface Panel: A side-mounted panel equipped with needle valves and pressure gauges simplifies umbilical connection and allows for easy system testing and monitoring.
- Corrosion-Resistant Construction: Built for the harshest conditions, the entire unit is housed within a single frame, treated with a RAL 5015 paint system compliant with Norsok M-501 Edition 1 standards.
- Lifting Points: Integrated lifting lugs facilitate easy and safe transportation and installation.
