Shipboard Computer

Survey (continued)

Ucean Motions Company software and hardware for tasks ranging from traditional trim, stability and strength to very sophisticated sta- bility calculations in wind and waves. Ocean Motions offers Ship

Loading Programs for operation on all IBM PC, PC-XT and PC-AT computers, with fully illustrated user manuals, and also a series of

Ship Loading Computers, which are fully marinized against shipboard shock, vibration, power transients and line noise. All Ocean Motions software is menu driven with simple prompts and complete input error checking. Six loading conditions are preprogrammed for immediate re- trieval, and tonnage, ullage, specific gravity and percent-full changes to bring the nearest condition in line > Thrusts Underway > Thrusts While Pitching • No Reversing Impeller to Change Directions > Minimum Buoyancy Loss » Smaller Hull Penetration » Fuel Savings

OMNITHRUSTER DOES IT ALL! > Thrusts with nozzles out of water in rough seas : vertical systems only. » No protrusions ... no change in hull shape. » Small nozzles reduce drag . .. save fuel and passage time. » Easily retrofitted.

Micro-Processor Control

System, Model 1200A . . with gyro input . . . holds vessel's heading. System also accepts compatible

NAV/AIDS lore alt and slow speed propulsion and positioning.

MODULAR THRUSTER SYSTEM . . .

OMNITHRUSTER ship control systems* utilize individual module thrusters of up to 3000 HP in any combination to produce desired forward or lateral net thrust. Prime movers for the

Modular Thruster System may be electric, hydraulic or diesel powered in conjunction with manual/automatic or integrated control networks.

ADVANTAGES FOR LARGE VESSELS ... • Incremental Thrust Capability • Multiple Module Reliability • Easily Retrofitted or Installed in New

Construction • Minimum Maintenance

Circle 150 on Reader Service Card with the user's required load out. In containerships, the stowage/load/ discharge sequence is continuously tracked and presented to the user so that he retains the most practical and efficient container distribution.

Sophisticated calculations of any stranded, damaged, flooded and in- tact ship are made easy for the load- ing officer/master/shore manager by very carefully written minimum in- put algorithms. Also available from

Ocean Motions is the new Stability

Alarm, which is absolutely unique and a definite breakthrough in ship- board computer technology. It con- tinuously and automatically senses ship stability. Not to be confused with a traditional loading computer, the Stability Alarm is entirely auto- matic with no user inputs. It is in effect a navigation feedback device, telling the helmsman how his head- ing and speed increase or decrease the vessel's stability. Recent instal- lations and orders for Ocean Mo- tions include the General Dynamics

Maritime Prepositioning Ships,

Avondale T-AO 187 fleet oilers, So- hio West Coast tankers, USCG barge monitoring, Western Geo- physical and many other commer- cial vessels from 30-295 feet.

A.S. SKARPENORD

Circle 14 on Reader Service Card

A.S. Skarpenord is manufacturer of Cargomaster computerized tank monitoring systems for closed level gauging, temperature monitoring and inert gas pressure monitoring in one system. The system will also measure the density/specific gravity of the cargos and present the vol- ume and weight in each tank, groups of tanks or all tanks jointly. An on- line/off-line loading computer, draught measurement, cargo line pressure and automatic pump and valve control can be integrated in

Cargomaster. The system is based on a specially designed pressure/ temperature sensor. The installa- tion has no moving parts and can withstand all types of tankwashing.

The materials selected for the sen- sor are of highest quality nickel alloys, resisting the most aggressive acids. Cargomaster has since 1979 been installed on chemical, products and crude oil tankers with excellent results. The system has also been installed on semi-submersible rigs under the name Rigmaster for bal- last control, draught measurement and stability calculation.

SPECTEC CONSULT A.S.

Circle 15 on Reader Service Card

The AMOS-D marine mainte- nance program has been developed by SpecTec A.S., the daughter com- pany of Arnesen, Christensen &

Co., one of Norway's oldest and most respected shipping consultant firms. The system is based on

Arnesen, Christensen's 70 years of experience in the field and has been developed through intimate cooper- ation between SpecTec's own in- house maintenance engineers and computer specialists. Most recently, the AMOS-D system was installed on the M/S Mariella, Viking Lines' luxury passenger ferry. AMOS-D provides the user with full control of maintenance planning and report- ing while simultaneously winning the struggle for coordinated spare parts administration. With AMOS-

D, a complete overview of what needs to be done, what has been done, who did it, when and where, plus the kind of "bird's-eye view" of parts inventory that maintenance supervisors need, are all available at the touch of a key. Automatic and selective parts requisitioning, one- key search for components and spare parts, full library of vendors, detailed information at all levels and statistic routines for spare parts consumption and maintenance ex- penses are standard features. The system is based on a logically struc- tured menu interface which guides the user to the desired operation with clear instructions, written by maintenance experts instead of computer programmers. This menu interface has grown and matured through the several months of test- ing on actual installation sites and through feedback from users work- ing with AMOS-D daily. SpecTec has installed over 50 systems and instructed some 100 maintenance engineers.

STANWICK CORPORATION

Circle 16 on Reader Service Card

The Stanwick Maintenance Man- agement System integrates preven- tive maintenance and repairs with a management information system. It provides preprinted maintenance work orders and collects cost and repair data for each item of equip- ment maintained. Complete ma- chinery histories can be printed on command. Other reports include ex- ecutive summaries of maintenance not accomplished, maintenance la- bor and material and material ex- pended and repair labor and materi- al expended. Stanwick's programs are designed to run on IBM-PC microcomputers. Stanwick offers programs for onboard inventory control and preventive mainte- nance. The Spare Parts Inventory

Program prints a list of spare parts according to a shipping company's numbering system, cross-referenced to a manufacturer's or vendor's part number, associated costs, quantities on hand, on order and order date.

The listing provides an interface be- tween the ship's crew and the pur- chasing department ashore. Reports include stock status, reorder re- ports, excessive parts on hand and inventory value.
