Fully self contained and believed to be the smallest AIS on the market, the new AIS features a digital display and control panel which can be easily mounted within any bridge layout with simple cable runs to other bridge equipment and antennas. The unit measures just 6.5in wide by 3.4in high by 7.4in deep. It is based on a proven DSC Class A VHF radio which is used to broadcast and receive position and identification data through its integrated STDMA controllers. The result is a cost-effective solution for vessel operators seeking full compliance with IMO MSC 749(69) Annex 3 carriage requirements.

The Minimum Keyboard Display (MKD) complies with IMO specifications to show all AIS equipped vessels within VHF range, which are identified by name, Maritime Mobile Security Identity (MMSI), range and bearing. The unit can also provide input to ECDIS and ARPA radar displays to ensure optimum presentation of AIS data.

The standard equipment pilot port enables any user to attach a portable AIS compatible display system directly to the transponder unit for presenting data at a location away from the unit. This can consist of any display system capable of recognising the NMEA AIS data string and might include a laptop or hand held PC.

The new AIS provides the option of being operated in receive mode only, a feature potentially beneficial for port controllers as it can contribute to reduced VTS display clutter when the ship is berthed or at anchor.

The new Ocean VDR is the result of a detailed development programme aimed at overcoming the difficulties associated with installing such equipment on board older ships. This has been achieved by developing technology that enables a single cable to carry all data to the VDR from a specific area of the ship, reducing copper and fibre-optic cable runs to an absolute minimum and so reducing installation costs substantially.

The ease of installation is also expected to benefit operators by minimising disruption to their sailing schedules, with S G Brown engineers expected to be able to undertake most installation work during scheduled stays in dock or while the ship is underway.

The Ocean VDR can convert and accept information from every type of data generating device on any ship, effectively eliminating the basis for any VDR carriage exemption that some operators of older ships might attempt to claim with their flag state.
