Equipment — Hercules (continued from page 33) unloading times have been re- duced from as much as 48 to eight hours because the UHMW polymer allows material to slide out, not bulk up requiring lengthy times to get the last portions out.
Shippers cite average times of 16-20 hours have been reduced to a mere eight, at cost savings of several thousand dollars per trip.
An additional benefit is that 1900
UHMW polymer has virtually zero moisture absorbtion; mate- rials slide easier wet or dry.

Kockumation AB of Malmo,
Sweden, one of the world's lead- ing producers of loading instru- ments, is now marketing the Load- master B20, the most advanced that the company has produced.
It can instantly update a loading condition for fast decision-mak- ing. It can simulate all stages of a loading condition in order to identify the optimum solution. It allows the operator to store dif- ferent loading conditions for fu- ture reference. It provides per- manent storage for three loading conditions approved by a classi- fication society. It can be con- nected to a level-gauging system.
And it minimizes the risk of hu- man error.
Kockumation's Loadmaster C30 model is a digital stress calcu- lator. The system consists of a general-purpose minicomputer, a floppy disc storage medium, an alpha-numerican display, and a hardcopy unit. The program can be adapted to suit the require- ments and operational routines of each individual customer.
The latest Loadmaster intro- duced is the V40, a fast, compact instrument that despite its low price is as flexible and powerful as the B20 over a wide range of applications.
The Loadmaster D50 calculates deadweight, forward 7 aft draft, bending moments and shear forc- es. An option is available for cal- culations of actual and required ship's stability. The D50 is a com- pact digital instrument—the com- plete calculator for cargo distri- bution.
The Loadmaster G70 is a com- puter that gives simple answers to difficult questions. It provides fast, accurate, and above all sim- ple answers to questions about the effects of cargo distribution alternatives on stability, draft, trim, and deadweight. The data and results displayed on the panel can be obtained in a printout, eliminating the need for time- consuming manual documenta- tion.
