Use Of Helicopter To Install 18 Tank Cleaning Machines

Saves Operator $37,000 And Time

How can 18 tank cleaning machines for crude oil washing be permanently retro- fitted onboard a 101,500-dwt ore/bulk/oil carrier when its decks have too many hatches to use sheerlegs and the sea is too rough to use a floating crane?

The superintendent of a six-year-old Great

Eastern Shipping Ltd. vessel, the Jag Laadki, was faced with just that problem, and solved it. What's more, an unprecedented $37,000 and nearly 2l/> days were saved in the process.

It began when the operators of Great East- ern decided that the Jag Laadki — already equipped with an inert gas system — could provide additional operating efficiencies by switching from water to crude oil washing (COW).

They selected the LAVOMATIC® (SA) tank cleaning machine manufactured by But- terworth Systems Inc., because of its highly efficient use of crude oil as a washing me- dium. By means of a cam-operated, variable- pitch impeller, the LAVOMATIC (SA) unit can be adjusted to slow its rotational speed when washing critical areas such as tank bottoms, and to increase its speed when washing noncritical areas such as tank sides and tops. This speed programming feature can result in up to 60 percent reduction of both cleaning time and wash fluid used.

Heavy seas and winds up to 30 knots pre- vailed as the Jag Laadki sailed into Balti- more, Md., and docked alongside a long, nar- row jetty to take onboard the 18 LAVO-

MATIC SA machines delivered by Butter- worth Systems. The rough weather ruled out the immediate use of a floating crane for the installation of these machines, while the complex hatch work on the Jag Laadki made it impossible to use sheerlegs.

Faced with substantial losses due to ex- pensive ship downtime, Captain Shah came up with an innovative method for raising and positioning the LAVOMATIC SA ma- chines. He chartered a local helicopter.

With the 18 LAVOMATIC SA machines lashed amidship, the Jag Laadki proceeded to the mouth of the Delaware River and a rendezvous with the helicopter. There, a high-risk complication was discovered. The vessel's inert gas system was malfunctioning, and her tanks were filled with a potentially explosive atmosphere. Ever resourceful, Cap- tain Shah ordered all tanks flooded with sea- water to eliminate any chance of explosion.

The helicopter was able to land on the Jag

Laadki, where the pilot reviewed the instal- lation plans with Captain Shah and the crew.

One at a time, the helicopter swiftly lifted each LAVOMATIC SA tank cleaning ma- chine from the deck of the Jag Laadki, po- sitioned it over the designated hatch open- ing, and lowered it precisely on target. The on-deck installation crew carefully guided each machine into place where it was per- manently secured.

Captain Shah's innovative decision to use a helicopter to install this equipment resulted in considerable savings for the Great Eastern

Shipping Company. Expensive ship downtime was avoided, and actual installation time and cost were greatly reduced. A look at the bot- tom line verifies this.

A floating crane would have completed the installation in three days at a cost of $40,000.

Using the helicopter took only 13 hours—12 for ballasting and deballasting, and only 1 hour for the helicopter installation. The ac- tual cost was only $3,000. Hence, a saving of $37,000 in installation costs alone. 12 Maritime Reporter/Engineering News
