lustrations, this impressive bro- chure unfolds to reveal a large re- production of the DataBridge-7

ARPA console. One of the major breakthroughs in modern naviga- tion has been the development of the automatic plotting aid (ARPA), and now at the touch of a switch, an officer can insure accurate and auto- matic plotting and logging through the additional features provided for the system. The main innovation has focused on extending the sys- tem's unique radar map overlay functions by adding unlimited stor- age capacity, an X/Y track plotter, and datalogger. Another optional feature allows radar maps to be sta- bilized with the aid of navigation data where fixed points for radar tracking are missing. Norcontrol's

DataBridge-7 is a third-generation

ARPA that acquires and tracks up to 50 radar targets and continuously displays collision avoidance data on the most threatening 20. It will sound a collision-warning alarm whenever any of these targets ex- ceed user-specified values for clos- est point of approach and time to closest point of approach. As a colli- sion-avoidance system, DataBridge- 7 meets or exceeds IMO recommen- dations and USCG and Maritime

Administration standards.

Circle 12 on Reader Service Card • DataChief-7 Monitoring and

Control System—This eight-page color publication explains that the chief function of DataChief is to monitor the running condition of the ship's main propulsion machin- ery. In addition, the system moni- tors the main machinery's second- ary parameters and controls motors, pumps, etc., to ensure optimum run- ning efficiency. The DataChief-7 is based on microprocessor technology and satisfies the classification soci- eties' requirements for unmanned operation of engine rooms for both diesel and steam-turbine ships. A ring data highway links a number of dedicated distributed microproces- sors to a central control station, with the choice of local or central readout facilities. Standardized modules together with the ring data highway minimizes the possibility of system failure and ensures a high degree of redundancy without the need for extra components. Full sys- tem control is achieved from one or more operator stations via a variety of displays and functional key- boards.

This eight-page color brochure explains that Norcontrol's cargo handling systems provide continual and accu- rate information on level measure- ment for cargo ballast and fuel tanks, on-line assessment of ship stability, vessel list and trim, hull sheer force and bending moment, etc., as well as providing cargo re- ports including damage stability.

These systems were first introduced in 1971 and have been installed onboard tankers, bulk carriers and

RO/RO-container ships.

Circle 15 on Reader Service Card • Vessel Traffic Management

Systems—Norcontrol's vessel traf- fic management systems significant- ly reduce the risk of ship collisions with offshore oil and gas installa- tions, both on the surface and sub- sea, according to this 12-page color brochure on vessel traffic manage- ment for coasts and ports. The traf- fic surveillance system provides the operator with a detailed presenta- tion of the traffic situation within the actual surveillance area together with continuous information on all vessels' positions, course, speed, range and bearing. Surveillance of traffic is undertaken centrally and the system may be tailor-made for offshore production fields, harbor areas and critical channels. It is based upon signals from a virtually unlimited number of radars, and the traffic situation thus detected is presented on the operator's console together with programmed informa- tion such as subsea installations, traffic lanes, boundary lines, an- choring areas, etc., and speed and course vectors for moving targets.

All data concerning target move- ments may be recorded for later playback. Extensive warning func- (continued from page 96)
