Data acquisition and processing

Typically, AMS6 system incorporates four Allen Bradley marine certified programmable logic controller units, one for each mooring location (usually four corners). Each unit processes data – sampling, scaling, calibration, etc. – from the sensors on the anchor winches.

INCONTROL can deliver the best suitable sensors and transducers, such as load cells, load pins, proximity sensors, encoders, etc., to meet the environment and application requirements. Additionally to the standard monitoring parameters – tension, length, speed AMS6 local instrumentation can be customized and adapted for monitoring other parameters in the field.

AMS6 has been designed with anchor line over speed detection and control feature. The anchor winch braking system can be easily interfaced with the over speed dedicated PLC digital outputs. This function can be very useful for limiting the pay-out speed of the anchor line in normal operation or during an anchor line Emergency Release situation.

The AMS6 anchor monitoring system has been designed to monitor the main parameters (length, tension and mooring speed) of the anchor line – chain or wire -, on semi-submersible rigs. Using open system architecture and high-tech certified automation devices, AMS6 is engineered to comply with the latest marine standards and regulations for industrial monitoring and control systems.


Things you can achieve by choosing INCONTROL AMS6 system:

  • User friendly interfaces
  • Real time data monitoring and logging
  • Optimized alarm management system
  • High speed device communication network
  • Cost efficiency
  • Is upgradable and … more …


Our Human Machine Interface application developed for the local Allan Bradley monitoring operator displays is optimized for the best look-and-feel results: visualization, design and user friendlyness. The standard AMS6 system includes one operator display unit per mooring location – typically four anchor winch cabins, but if it is required, supplementary units can be added.

A very useful feature of the HMI application is the Cross Tension screen. This gives the anchor winch operator the flexibility to monitor, from one location, the anchor line parameters of all anchor winches on the installation. Some other features of the INCONTROL HMI are zooming, trending, alarms management (acknowledgment, silencing, historical logging), custom settings.

Using industrial Ethernet switches connected through an optical fiber layer in a ring topology, communication network architecture between AMS6 devices at different levels has been designed to achieve maximum speed performance and node redundancy at the same time.


At the supervisor level, the graphical user interface designed for the central unit, located in the barge control room, shows the real time continuous readings, of the main anchor-line parameters from all mooring locations. The supervisory unit is a robust and flexible fanless industrial computer suitable for marine operations. One of the main important features of the supervisory computer is the system health monitoring function. The user is notified through different alarm messages about any malfunction detected in the AMS6 network hierarchy. Optionally, the supervisory computer can be interfaced to provide useful information about mooring line parameters to third party systems, such as dynamic positioning systems, centralized data acquisition systems, centralized alarm systems etc.

Remote service and support

Using the VPN routing technology, INCONTROL offers the possiblity of remote maintenance for the AMS6 product. The solution is based on establishing a secure, encrypted, bi-directional tunnel through internet between INCONTROL office and AMS6 network, using a dedicated industrial VPN router.

By using the remote maintenance solution the following features must be considered:

  • Improved quality and reliability of digital data transfer
  • Improved security by using the encrypted data transfer VPN tunnel
  • Accessability
  • Fast software debugging and upgrading
  • Cost savings with the remote software maintenance
