Trim and Heel | Display Monitoring System

Connect TH Series – a dedicated Trim and Heel monitoring System

Connect DI Series – a dedicated Draught monitoring System

The Scanjet PSM Connect -TH and Connect DI systems are based upon PSM’s established Connect vessel monitoring system, and are suitable of all Vessel types.

Connect TH is configured specifically for the monitoring and display of vessel trim and heel. Comprising a central display with a 7″ touchscreen, and a single remote wall mount enclosure with dual inclinometers to measure trim and heel angles, the system is supplied pre-configured with all parameters relevant to the intended application.

Installation is simple, the display can be located as required in the bridge / control room requiring only a single 24V DC supply, and the inclinometer enclosure on a suitable vertical bulkhead, with a single 4 core interconnecting cable.

Display of both instantaneous and averaged Trim and Heel values are provided in user required units. The averaging period and preference of whether trim by stern is positive or negative, and heel to port is positive or negative can all be set by the operator. Repeater displays can be added as required and are connected to the primary display via a dedicated Ethernet link.

The system includes correction parameters to allow the installer to correct for the “as fitted” position of the inclinometer panel to ensure true zero at even keel conditions. In operation the user can switch between dark and light display modes for night / day operation and the averaging period can be adjusted to optimise stability of reading for the averaged values of Trim and Heel.

A further RS485 port on the primary display allows connection to the vessels central AMS / Platform Management System. The exchange protocol is standard Modbus RTU where the AMS/PMS is Modbus master and the PSM system is Slave.

Connect DI is a dedicated vessel draught monitoring and display system. The system can be configured for single, 2 point (Forward & Aft), or 4 point (Forward, Aft & Midships) monitoring.

Measurement of draught levels is taken care of by PMS’s APT1000 level transmitters which are connected directly to the central display communicating via Modbus RTU. The central display is configured with the location of each APT1000 with respect to the Vessel’s hull draught markings, and includes correction parameters to enable true “draught at the marks” to be displayed. In operation the user is able to make initial corrections to displayed values by entering visually observed values to ensure the systems accuracy.

For systems with a single draught measurement point, the APT1000 is positioned centrally to the vessel and an inclinometer measures the trim angle to allow projected readings for Forward and Aft.

If required, the vessels current Trim (and Heel where a 4 point system is installed) may also be displayed based on actual measured draught values and the specifically configured dimensional parameters of the vessel.

As the Connect TH system, Connect DI also has a Modbus output which can provide information to other shipboard systems.

Depending on the specific requirements of a particular Vessel the two systems may be combined to provide both Vessel Trim/Heel and Draught display. PSM will be pleased to discuss your particular needs.
