Base Station Monitoring Systems
Real time load display is available via telemetry communications with the CALM buoy.The SPM-LMS-02 system is provided with a base station consisting of the telemetry communicationinterface, PC based operators workstation with LCD monitor, and report printer.The dedicated Harbour Marine operating software allows clear display of hawser loads withstructured reporting and editing of load information.Load data and alarms are recorded at the Base Station for future analysis. An interface may be
provided using industry standard protocols such as MODBUS allowing loads and alarms to be readby the plant based DCS.
Hand Held Wireless Monitors
Hand held monitors may be added to systems SPM-LMS 01 or 02 to monitor load and alarm information. An SPM monitoringsystem can support multiple hand held units which may be issued to parties having a vested interest in monitoring hawsertensions. Features include:
Over all size in mm 83(Length) x 53(Height) x 16(Depth). Mass 65 grams Display screen automatically refreshes with new data every 10 seconds Alarms are prioritized with audible alert Degree of protection IP 68 (within pouch) Self powered using replaceable batteries Intrinsically Safe for Zone 1 & 2 hazardous area Multiple units can be supported over a range of 4 to 10 KM
GPS Position Monitoring
The SPM buoy systems may incorporate GPS positioning complete with tilt sensor and gyro providing heading, position and
via the system software, excursion of the buoy.The relative position of the buoy and vessel may be monitored during vessel approach and following its connection to thebuoy.Data can be transmitted to a portable or fixed base station over the common system telemetry link and positioning informa-tion can be graphically represented by the dedicated software.

Single Point Mooring (SPM) Monitoring
For the Real Time monitoring, broadcasting and recording of hawser tensions that develop during the mooring of a
vessel to a CALM buoy or SPM offshore oil facility.
The system provides hawser tension warnings and information in an effective and
timely manner allowing the vessels Master time to attend to potential mooring
problems in the event of Low Near High or High-High hawser tension.
Other options that may be integrated and supported on the SPM monitoring systeminclude:
Navigational aid operation and status
Product pressure and flow monitoring
Relative position monitoring of the buoy and vessel using GPS
System Configuration
Load Monitoring is available for either single or dual leg hawsers and the system may be provided as an upgrade or replace-
ment to an existing CALM buoy. Standard system configurations include:
SPM - LMS-01: The basic Harbour Marine system isfully contained onboard the SPM itself. Load data
recording is performed locally and stored for later
retrieval. Audible / visible hawser tension warning
lights and sirens are installed on the buoy to alert
the vessel crew.
SPM - LMS-02:Building on the above system a
remote Base Station Monitoring system may be
installed onshore with monitoring operation and
diagnostics performed over UHF telemetry communi
cations.
Enhancements to the above systems may also include:
A Portable Operators Workstation
Hand Held intrinsically safe monitors to receive loads
and high load warning
Features of the Buoy Mounted Equipment
Load Cellsare designed to suit the tri-plate or pad eye connection for most styles of new and
existing CALM buoys.
Buoy Controllercontains the control system microprocessor, load cell interface, navigational aid
control, data logger and telemetry equipment depending upon the system configuration and options
chosen. The controller is generally located on the deck of the SPM within an explosion proof enclo-
sure. A unique design feature of Harbour Marine systems is that the controller is double sealed
within a second outer stainless steel enclosure providing superior marine protection. This ensures
that the inner explosion proof controller remains in a fully protected and serviceable state resistant
to the harsh external environment.
Telemetrysystems developed by Harbour Marine for offshore applications have a proven history of reliability spanning 20
years. Hawser loads and load alarms are transmitted over telemetry from the buoy system in real time to portable or fixed
workstations located on or offshore. Telemetry is UHF band and incorporates inputs for load cells, battery monitoring, and
optional line pressure; navigational beacon photocell; navigational aid status. Other optional interfaces are available for
anemometers, temperature and humidity sensors.
Power Supplyto operate the buoy equipment is provided from deep cycle batteries which are solar charged and micro-
processor controlled and monitored to provide automatic load shedding, temperature compensation and charge status. The
power status may be interrogated from the Base Station Monitoring System.
