Ballast control systems are a vital part of semi-submersible oil platforms. The ballast control system is made up of a network of pipes, valves, pumps, and tanks, which work as a liquid control system to keep the vessel at an even keel. Offshore drilling is an extremely risky undertaking, which is susceptible to accidents, which may cause human casualties and environmental disasters. One of the key systems necessary to keep oil rigs afloat, is the effective design of the user interface for the ballast control system, which significantly contributes to overall safety of a rig’s crew and the environment. The threat of disaster is the main reason to provide the operators with the most effective ballast control system possible. One such disaster occurred in 2001 aboard Petrobras’ P36 oil rig.
