Tank Deck Control
Tank Deck Control is a marine control system installed on ship tank decks for remote operation and management of valves and tank-related equipment.
The system provides a centralized operating location on the deck, allowing crew members to control cargo tank valves, ballast valves, and other marine piping equipment safely and efficiently.
Tank Deck Control is mainly used in:
Oil tanker cargo systems
Chemical tanker systems
Fuel oil tank systems
Ballast tank systems
Marine liquid handling systems
By connecting with remote valve operating mechanisms, Tank Deck Control enables operators to control valves located inside cargo areas or other restricted locations without direct access.
Overview
Working Principle of Tank Deck Control
Tank Deck Control works by transmitting operation commands from the tank deck control position to remote valves or tank equipment.
The system can operate through:
Mechanical shaft transmission
Gear operating mechanisms
Hydraulic control systems
Cable remote control systems
Operating Process:
Operator operates the control handle or handwheel on the tank deck.
The control mechanism transfers the operating force.
The remote valve actuator receives the movement.
Cargo, ballast, or tank valves open or close.
Valve position can be monitored through indication devices.
