are compact for easy positioning at various points aboard ship. The clearly laid out panels provide continuous analogue information at up to 100 levels, along with al- pha-numerical information on alarm levels, temperatures, weights, volumes and other vital data. All indicated levels can be corrected for trim and list at the push of a button. For maximum safety and con- venience, all tank levels can be transmitted to the Loadmaster B24 for on-line calculation of the ves- sel's stress and stability. By incor- porating control of valves and pumps, the system can be ex- tended to an integrated Cargo Handling System. For those vessel operators wish- ing to employ Kockumation's ex- pertise in calculating stress and stability but not wanting to pur- chase a dedicated loading instru- ment, Kockumation is now offer- ing software for use with Nav- Com's BUSISHIP work station. The combination of two major ma- rine electronics companies strengths provides a versatile, multi-purpose vessel management system which can be supported around the world! Circle 5 on Reader Service Card viewing screen. An extremely pre- cise XY mechanism positions the microchart behind a cross hair on the view screen which represents the "own ship" position. These mi- crocharts are permanently mounted in durable cassettes and are se- lected for a specific coverage area and scale in the same manner as a corresponding paper chart. Passage planning features in- clude manual entry of bearing fixes, waypoint sailing, and navi- gational hazard markings. If de- sired, course to steer information can be provided to an autopilot. Circle 6 on Reader Service Card SUMMARY OF CURRENT SYSTEMS PROJECTS As a summary to the technical session, Nav-Com re-emphasized the benefits of integrated systems by describing several projects for which their engineering services had been contracted. Their most recent project involved the most sophisticated yacht ever built in the United States. Reading from an equipment list five pages long, nearly every element discussed during the seminar was included onboard the motor yacht "Grand Cru". In addition, a vessel moni- toring system will check over 260 points throughout the vessel. Jack Provenzano, Nav-Com's executive vice president and direc- tor of engineering, stated that the vessel could be operated, safely and efficiently by a crew of one. Attendance of the seminar ex- ceeded one hundred people with an equal split between the public and private sectors. The audience included senior executives from the U.S. Coast Guard, Federal Communications Commission, De- partment of Navy, U.S. Army Corps of Engineers, National Oceano- graphic and Atmospheric Admin- istration, several naval architects, shipyards, and major merchant fleet operators. r.

Kockumation of Malmo, Sweden is one of the world's leading inno- vators and producers in the field of automated marine equipment. Systems solutions are a key con- cept at Kockumation. The presentation given by Kock- umation at the Nav-Com Seminar centered around the NLM 200 level-gauging system. The NLM 200 provides the flexibility to choose the best sensor for each ap- plication. There is virtually no limit to the different types of sen- sors that may be required. A tai- lor-made, automated system is de- veloped for each type of ship. Level-gauging in cargo tanks is highly specialized. Sensors vary widely with the commodities being carried. For example, aboard chemical tankers, sensors in con- tact with cargoes are made of stainless steel. Performance must be independent of viscosity, tem- perature, foaming surfaces and re- flectivity to provide maximum safety. Aboard crude oil or product carriers, Kockumation offers a Magnetic Float Gauge. This new technique is rugged enough to op- erate during tank washing and at sea without being damaged. In the miscellaneous vessel service tanks, a variety of pressure transmitters are used to sense levels of fuel oil, lube oil, freshwater and ballast.

Introduced as one of the most significant advances in naviga- tion, this automatic visual posi- tioning aid does offer some unique capabilities. The Bowditch Navi- gator provides the bridge team with a continuous automatic dis- play of the vessel's position on a standard nautical chart. As an in- tegrated navigation system, the watch officer can select an operat- ing mode of Loran, Satellite, Omega, Decca or Dead Reckoning and the vessel's position will be updated by that mode's incoming data. The visual display of ship's po- sition on the nautical chart is de- rived from an optical projection of a "microchart" onto the unit's 1500 Ton Dock 160' x 80' 70' Between Wing Walls HISTORY Founded in 1948, Main Iron Works, Inc.'s current facilities are available for construction of new vessels ranging in size from 45' to 250' in length Dry docking and a full range of repair services are also available, including a complete machine shop facility, sandblasting and painting services.
