Colt Industries To Furnish

Sewage Treatment System

For East Coast Ferryboat

A sewage treatment system for shipboard service, which was designed and built by Colt

Industries' Power Systems Division in Beloit,

Wis., will be installed aboard a 390-passenger ferryboat operating on the East Coast. The announcement was made by F.J. Eubank, vice president and general manager of the water and waste management operation.

The ferry Uncatena is operated by the

Woods Hole, Martha's Vineyard and Nan- tucket Steamship Authority in Massachusetts.

The boat is scheduled for enlarging and mod- ernizing in the fall, and the sewage unit will be installed before she returns to duty. John

J. McCue, general manager, and A.E. Libbra, maintenance superintendent, are in charge of the project.

For some time, Colt Industries has manu- factured these pollution control units for mili- tary vessels, but this will be the first ferryboat application. The equipment that will be placed on the Uncatena is rated at 5,800 gallons per day.

This sewage treatment system is an electro- chemical design which eliminates solids by odorless, smokeless combustion and dispenses a clean, pathologically safe effluent overboard.

The liquid discharged from this system meets current official requirements for preservation of water quality. The compact units make any ship self-sufficient in preventing harbor pollu- tion from sewage system discharges. "We at Colt Industries are heavily engaged in research and manufacturing of marine pol- lution control equipment and water desalting systems," Mr. Eubank commented. "Our sew- age treatment systems are designed for many marine applications and our desalting plants are built to produce fresh water where it is needed around the world."

Bethlehem Hoboken Shipyard

Uses Unigue Technigue To Cut

Tanker Repair Time In Half

Craftsmen of Bethlehem Steel's Hoboken, N.J., ship re- pair yard rebuilding the rudder for the 28,000-dwt tanker S/S Eagle Courier.

A unique technique developed by Bethlehem

Steel's Hoboken shipyard has halved the repair lay-up time for a tanker which recently lost most of her rudder in a North Atlantic storm.

When the 28,000-dwt tanker S/S Eagle

Courier arrived in the port of New York late in March, it was learned that three-quarters of her 30-foot rudder, including the lower casting, had been lost. Her owners, United Tanker Cor- poration, checked area shipyards and learned that the repair job would take from 40 to 60 days as it would require approximately six weeks to manufacture the lower rudder casting. This

L-shaped unit had a length of 4 feet 10 inches, a width of 27 inches, and a depth of 20 inches.

Overall, the lost section measured 23 feet 9 inches by 12 feet. The upper rudder casting, 10 feet by 6 feet, remained intact.

At this point, the Bethlehem yard advised the owners that through use of a new technique they could manufacture a substitute steel section to replace the original casting and cut the vessel's projected lay-up time in half. The process, which has the approval of the American Bureau of

Shipping and the U.S. Coast Guard, involves the welding of steel plates and has been employed successfully by the Hoboken yard heretofore.

United Tankers gave the Bethlehem yard the "go ahead," and on March 26 the Eagle Courier entered the Hoboken yard. On April 14, only 20 calendar days later, the tanker—with her rudder fully restored—put to sea and resumed her serv- ice.

Because of the proprietary nature of the proc- ess, details cannot be made available at this time.
