Two Colt-Pielstick PC 2 V-14 engines are the main power units on the M/V SEABULK MAGNACHEM, an ultra modern 39,900 ton integrated tug/barge owned by Hvide Shipping Company of Port Everglades, Florida. When the vessel was commissioned, Gulftow® Special 30 was chosen as the lubricating oil. Since the engines use fuel with a sul- fur content as high as 1.9%, with a viscosity of 1121 SSU at 100° F and vanadium at 32 PPM, sodium at 38 PPM, that's tough duty for any oil. Gulftow Special 30 stood the test. (Left) The M/V SEABULK MAGNACHEM in port at Mobile, Ala. for drydocking and overhaul of engines.

And when the engines were torn down and inspected, the piston skirts were clean and smooth, with no scoring, and all rings were completely free. Hvide carefully con- sidered the demands these conditions would place on an oil before choosing Gulftow Special 30. They chose it for stability, long life and superior protection in the tough marine environment. Careful lubricant selec- tion is only part of Hvide's meticulous maintenance program. They con- stantly monitor the performance of this vessel's engines on sophisticated monitoring consoles reading in both the engine room and on the bridge. And they use Gulf-Check tests on a regular basis to keep aware of oil close inspection and engine condi- noscoring- tion. It's this complete main- tenance program that al- lows Hvide to get such long and economical service from its machinery. In addition to using Gulftow Special 30 in the Pielstick Diesels, the M/V SEABULK MAGNACHEM Write 198 on Reader Service Card also uses Gulftow 193, Gulf Harmony® 68 AW, Gulf Har- mony 46 AW, Gulf E.P.
