tic. The principal output of the model is the month-by-month sum- mary for each route leg of maximum power required, fuel consumed, car- go delivered, attained speed, and cost per unit of cargo. The Transportation Planning Tool (TPT) is a simulation model designed to assist shipowners/oper- ators in optimizing the composition and deployment of a bulk fleet. The user of TPT specifies his required commodity flow pattern, lifting/de- livery constraints, and the mix of owned or controlled tonnage he pro- poses to use. The model calculates the delivery capacity of the speci- fied fleet, route-specific transporta- tion costs, and the number of voyage-chartered vessels that may be needed to meet the specific de- livery requirements. Circle 68 on Reader Service Card MCNAB, INCORPORATED McNab's Fuel Management Sys- tem is a self-contained package of dedicated hardware and software. It makes available a display of speed versus profit on a per-voyage basis for a particular ship. The system uses shoreside data containing ac- counting and scheduling informa- tion, as well as shipboard data rele- vant to vessel characteristics, and real-time data on the main shaft torque, rpm, and speed. Circle 69 on Reader Service Card MICRO MARINE LTD. This U.K.-based firm offers sev- eral packages for computerized planning and analysis. The Broker System provides an information re- trieval tool for brokers and owners. The database covers vessel details (characteristics and positions) and client information. Telexes can be generated automatically from the data files. The Voyage Estimating and Anal- ysis System consists of a sophisti- cated voyage estimating tool linked to a post-fixture voyage analysis program. It incorporates a distance table and historic port and canal cost data. The program calculates an optimum bunker plan automati- cally, and incorporates a steaming speed analysis feature. An Invest- ment Appraisal program performs cash flow, equity, and risk analyses for investment projects. Micro Ma- rine programs are designed to run on Apple II and IMB-PC/XT micro- computers.

Proprietary Nav-Com software handles a wide range of vessel business tasks, including po- sition reporting, purchase requisi- tions, requests for medical assis- tance, electronic mail, data logging, word processing, and automatic ac- cess to subscriber databases. Other application modules include vessel inventory control, personnel man- agement, voyage planning, and car- go loading calculations.

U INCREASES FUEL EFFICIENCY, DECREASES OPERATING COSTSl' / IVIERCIZE deposit modifier/ combustion improver Here's news that will save substantial money for shipowners-savings on fuel, down time and maintenance. You already know that the quality of today's marine fuels, with higher levels of contaminants, not only create operating inefficiencies, but can cause considerable damage to engine parts and leave harmful combustion deposits. To help solve your fuel problems, Drew Ameroid* Marine has taken the industry lead once again with AMERGIZE" deposit modifier/combustion improver. The introduction of AMERGIZE represents a major breakthrough in chemical additive technology. AMERGIZE, combined with the PACE fuel evaluation program provides a total worldwide service that will save you money. This unique product and service produces significant increases in fuel efficiency, while reducing breakdowns and maintenance. THE PRODUCT: A deposit modifier and combustion improver in one. AMERGIZE is a new, specially formulated, concentrated blend of organometallic compounds that combines both combustion improvement and deposit modification in one product. It improves diesel engine combustion. It reduces smoking. It decreases valve and turbocharger deposits. AMERGIZE is effective in diesel engines burning today's heavy fuels. AMERGIZE is non-abrasive and does not harm engine parts or close-tolcrance metering equipment. THE SERVICE: Dosage treatment analysis and PACE fuel evaluation. Today's refiners obtain a higher' yield from every barrel of crude they process. Unfortunately, that leaves you with higher concentrations of contaminants-the worst of these are unknown quantities of vanadium, sodium and sulfur. Drew representatives will assist ship managers in determining specific AMERGIZE treatment rates for bunker fuels high in these harmful contaminants. In addition, Drew Ameroid Marine offers the PACE" program. It provides you with data on the levels of contaminants in your present bunker fuel prior to dosing, and the best course of action to take in handling the fuel with maximum efficiency and minimum cost. Besides being one of the industry's most comprehensive fuel evaluation services, PACE is also the fastest and most economical. INDEPENDENT LABORATORY TESTS PROVE IT: Documented tests* by a recognized independent facility demonstrate conclusively that AMERGIZE significantly reduces specific fuel consumption, carbon deposits, exhaust smoke levels, and deposits. Tests were performed on a test-bed engine utilizing a residual fuel blend. Both visual and operating characteristics from the baseline and AMERGIZE treated runs were monitored and recorded. The results of these tests clearly prove the benefits of AMERGIZE: AMERGIZE substantially reduces carbon deposits, exhaust smoke levels and metallic deposits. AMERGIZE reduces fuel consumption up to 8%. The AMERGIZE program needs only a 1% improvement in fuel consumption to pay for the entire treatment. AMERGIZE realizes substantial additional savings and benefits in longer engine life, less frequent repairs and lower maintenance costs. AMERGIZE comes in 25 liter and 120 liter containers, and is available through Drew's network of service representatives in strategically located ports worldwide.
