Mechanical Installation Where to install Radascan The Radascan system is designed for permanent or semi-permanent installation at a suitable location on the installation vessel.
How to install the Radascan System Unpacking the Radascan System The whole Radascan system is supplied and shipped in a custom-built crate, Use the following procedure to unpack and prepare the Radascan System. To unpack the Radascan System 1. Position the Radascan crate on a level surface, close to the area where the sensor will be installed. 2. Remove the top panel and then the side panels from the crate. 3. Remove the securing bolts (M12) from the base of the Radascan system.
Cable Installation The Radascan system is supplied without cables that are necessary to connect the sensor to the DP system or to the PC control console. These must be supplied and fitted as required for a particular vessel installation by the installer. The installer must provide power to the Radascan sensor.
Console and DP Feed connections Console Connection You will require a shielded Ethernet cable, remove one of the screw heads from the M20 glands mounted on the hatch and feed the Ethernet cable through it. You will see a metal box in front of you with the LED display mounted on it, the Console Ethernet connector is located on the right hand side of this metal. Each connection is labeled appropriately.
Radascan Console Computer options The Radascan system is available with three different optional configurations of PC hardware to run the Control Console application. The wiring connections for each of these are shown here. Use the one that is appropriate to your PC hardware configuration.

Radascan Console set-up Once the full Radascan system has been installed on the vessel, a number of tasks need to be performed to ensure accurate operation. These are: • Location offsets – these define the exact position of the sensor on the vessel, • Vessel name – identifies the vessel and is included in all reports created by the Radascan system, • Log file creation – create and collect a log file to confirm the correct installation and operation of the Radascan system.
Entering service access mode There are many settings within Radascan Console that can seriously affect system operation if they are incorrectly adjusted. For this reason they are concealed until you enter service access mode. There are two ways to enter service access mode: • Insert an engineer’s USB key into one of the Console computers’ USB ports, or • Obtain a temporary service access code from either Guidance Navigation Limited or an authorized customer service representative.
Location offsets (requires service access) Location offsets allow you to define exactly where, within the outline of the vessel, the Radascan sensor is positioned. The location offsets are expressed as four values (length and breadth of the vessel, plus a bow offset and a starboard offset) held with the Configuration page tab of the property sheet. To adjust the location offsets 1 Enter Service Access mode using either an engineer’s USB key or a temporary service access code.
Vessel name (requires service access) The vessel name is displayed within the Radascan Console application and is also written to all activity logs that are produced. The latter is an important reason to enter the vessel name, particularly to avoid confusion between logs sent from different vessels. To set the vessel name 1 Enter Service Access mode using either an engineer’s USB key or a temporary service access code. 2 View the Configuration page tab within the Property sheet.
Additional shutdown menu features (requires service access) When service access mode is invoked, the Radascan Console shutdown menu displays an additional Exit option that is concealed during normal user mode: Radascan Installer – 15
Initial log file creation As part of the commissioning process, it is accepted best practice to initiate and store a log file of the Radascan system operation. The completed log file should then be archived and a copy also sent to Guidance Navigation Limited as a base reference for the system. Normally, the Radascan system creates automatic log files whenever it is navigating. For commissioning and diagnostic purposes, it is possible to force the system to create a log file while it is in standby mode.
Bearing offset (requires service access) The Bearing offset allows you to optionally correct any deviation of the Radascan sensor’s centre-line from that of the vessel’s. The bearing offset is calculated based on the direction of the Radascan sensor relative to the bow - irrespective of whether the sensor is mounted with its connectors facing the bow or the stern. To adjust the bearing offset 1 Enter Service Access mode using either an engineers thumb key or a temporary service access code.
4. In the Bearing Offset field, enter the exact angle by which the centre-line of the sensor deviates from that of the vessel. If the angle is to port (anti-clockwise), the angle must be positive. 5. Click the Apply button.
Operator training Aspects of Radascan and its use that should be described to a new user to complete the installation As part of the commissioning process it is important to ensure that the vessel’s DP operation staff are familiar and comfortable with the operation of the Radascan system.
Technical notes • Technical note 1: Target Transponder • Technical note 2: Target Installation • Technical note 3: DP message types • Technical note 4: Low temperature operation Radascan Installer – 20
TECHNICAL NOTE 1 Target types The Radascan sensor uses specific transponder targets.
TECHNICAL NOTE 2 Target installation Key to the operation of the Radascan system is the correct installation of targets. Please follow the guidelines given below when installing targets on the rig. Once the targets are installed, their relative positions can be automatically surveyed by the system. Installation tips • Targets should be placed in positions where the sensor can see them while the vessel is within the expected working area. Consider vertical position as well as horizontal.
TECHNICAL NOTE 3 DP message types Introduction The Radascan distinguishes between two operating modes; (a) single target/prism, and (b) multiple target operation which can affect the type of data sent to the DP feed. However, independent of this operation mode different DP feed message types can be selected from a range of formats. The DP message update rate is 1 Hz.
• CC computed checksum in hex • Carriage return (ASCII 0D hex) • Line feed (ASCII 0A hex) ASCII17 Format (0x0004) A 17 character string delimited only by and with bearing measured bow clockwise.
TECHNICAL NOTE 4 Low temperature operation Introduction Radascan is a precision electro-mechanical device with hardware components that, of necessity, are mounted in an external position on a vessel’s superstructure. It is recognized that industrial marine operations may subject these components to harsh environments, including low temperature. The standard variant of Radascan is designed to operate within the temperature range -25 to 55ºC.
