A Track Control System (TCS) controls the error relative to a planned route. Either it has an embedded autopilot function to keep a ship on the planned route, or it gives commands to an external autopilot. A Speed Control System (SCS) controls the ship speed.
A Ballast Control System may control trim, list and/or draft. A Dynamic Positioning Control System (DPCS) controls the position and heading of a ship at very low forward and reverse speeds. A Dynamic Tracking System (DTS) is a track control system able to function at low forward and reverse speeds.

What are the features of centralized control room in ships?
This chapter describes the features of central control room in ships
The normal practice in ships with centralized controls is to locate them in a control room fitted in a position which is of optimum convenience to the operator and giving as much surveillance as practicable of the main machinery
What is a propulsion control system?
The Propulsion Control System is a key feature of the automation systems on board a ship
In addition to ensuring safety and reliability, modern Propulsion Control Systems are also playing an increasingly important role in facilitating smooth and efficient operation of the ship
What is a ship control system?
These systems control and monitor platform machines, steering and on-board systems, and are comprised of sensors, actuators, remote terminal units and data processing to provide safe, secure, condition-based control, monitoring, steering and diagnostics on the status of a ship and its major systems
Control systems on ships
US class of dock landing ships
The Harpers Ferry class of the United States Navy is a class of dock landing ships completed in the early 1990s. Modified from the Whidbey Island class, the design sacrifices landing craft capacity for more cargo space, making it closer to an amphibious transport dock type, but was not designated as such. Externally, the two classes can be distinguished by the positions of weapons: The Harpers Ferry class has the Phalanx CIWS mounted forward, and the RAM launcher on top of the bridge, while the Whidbey Island has the opposite arrangement.
International Maritime Organization treaty
The International Convention on the Control of Harmful Anti-fouling Systems in Ships is a 2001 International Maritime Organization (IMO) treaty whereby states agree to prohibit the use of harmful anti-fouling paints and other anti-fouling systems that contain harmful substances. In particular, the use of the organotin tributyltin is prohibited, since leaching of that chemical from the hulls of ships has been shown to cause deformations in oysters and sex changes in whelks.
The Sea Control Ship (SCS) was a small aircraft carrier
Concept aircraft carrier
The Sea Control Ship (SCS) was a small aircraft carrier developed and conceptualized by the United States Navy under Chief of Naval Operations Elmo Zumwalt during the 1970s. Currently the term refers to naval vessels that can perform similar duties. The SCS was intended as an escort vessel, providing air support for convoys. It was canceled after budgetary cuts to the US Navy.
The Whidbey Island-class dock landing ship is a dock
United States Navy amphibious assault ship
The Whidbey Island-class dock landing ship is a dock landing ship of the United States Navy. Introduced to fleet service in 1985, this class of ship features a large well deck for transporting United States Marine Corps (USMC) vehicles and a large flight deck for landing helicopters or V-22 Ospreys. The well deck was designed to hold four LCAC hovercraft, five if the vehicle ramp is raised, for landing Marines. Recent deployments have used a combination of LCU(s), AAVs, tanks, LARCs and other USMC vehicles. The Whidbey Island class of ship also uniquely benefits from multiple cranes and a shallow draft that further make it ideal for participating in amphibious operations.
A white box system is a mechanical system installed in the engine room of a ship for controlling and monitoring the engine room bilge water discharge from the vessel.
