DockAlert™

Strainstall's docking system, DockAlert™, protects vessel and jetty infrastructure by measuring distance and calculating vessel approach speed to ensure it remains within allowable limits for safe operations.

DockAlert™ allows pilots and vessel masters to monitor vessel approach and take corrective action to prevent any incidents should the vessel speed or approach angle move outside the allowable limits. Once the vessel is safely moored, the docking system will also monitor any drift-off of the vessel and provide warning to operators.

The docking system uses eye-safe laser units installed on either side of the jetty head to measure the distance of the bow and stern relative to the jetty, while also providing speed and angle of the vessel to the berth.

The data from these lasers is fed to a central control system, where it can be displayed in the jetty control room and relayed to either hand-held pagers/PDAs and/or to a large digit display mounted on the jetty providing the pilot and vessel master with critical information.

DockAlert™ docking system benefits:

  • Protects vessels and jetty infrastructure by facilitating a safe berth
  • Enables larger vessels to dock without undertaking expensive infrastructure modifications
  • Improves vessel 'turn around' times
  • Improves safety

DockAlert™ docking system features:

  • Real-time display of vessel approach speed and distance
  • Reliable, low maintenance design
  • Operation is unaffected by weather conditions
  • High accuracy, increasing during the critical approach phase
  • Simple above surface installation
  • Provides alarms in the event the vessel moves outside selectable parameters
  • Event logging to provide historical data

How DockAlert™ works:

Jetty-based laser system

Strainstall's DockAlert™ system uses two eye-safe laser units installed on either side of the jetty head and aimed perpendicular to the berthing line. These measure the distance of the bow and stern relative to the jetty, while also providing speed and angle of the vessel to the berth.

The data from these lasers is fed to a central control system, where it can be displayed in the jetty control room and relayed to either hand held telemetry units (i.e. pagers and/or PDAs) or a large digit display mounted on the jetty.

The large digit display is visible from over 200m and provides the pilot and vessel master with data on the speed of approach and distance from the jetty.

Incorporated into the display are arrows indicating whether the vessel's speed is increasing or decreasing using simple traffic light indicators to warn of excessive speed. These can be set against pre-determined safe parameters to ensure smooth and gentle berthing.

Once the vessel is safely moored the system will also monitor any drift-off of the vessel and provide warning to operators.

Ship-based global positioning system (GPS) system

Strainstall can also supply a portable GPS system that is carried on-board by the pilot. It comes in a lightweight waterproof case that is placed on the bridge wing, with its two antennas attached to the vessel's railings by either magnetic mount or spring clamp.

Data is passed wirelessly to the display laptop, which the pilot can place in any convenient position.
