General Dynamics Awards

Contract To Build Two

Building Basins At Quincy

General Dynamics has announced the award of a multimillion dollar contract to Perini Con- struction Company of Framing-ham for the construction of two shipbuilding basins at its

Quincy Shipbuilding Division, Quincy, Mass.

P. Takis Veliotis, president and general man- ager af Quincy Shipbuilding Division, in mak- ing the announcement said: "Construction of these basins will be similar to our three exist- ing building basins and will allow us to com- pete effectively in today's market as well as future markets, not only for liquefied natural gas tankers, but for other ships of comparable size."

General Dynamics has contracts for $270 million to construct three LNG ships, and is currently negotiating with several companies for additional contracts.

Conversion of the shipways will mark the end of sliding-ty.pe launchings at the Quincy shipyard. Construction of the basins is expect- ed to be completed by the summer of 1974.

The last ship to be launched from the sliding ways was the Navy replenishment oiler Kala- mazoo, on November 11, 1972. She is in the final stages of fitting out preparatory to com- missioning-.

B&W Shipboard Disposal

Systems To Be Installed

On States Steamship Vessels

Three systems (for the disposal of shipboard wastes have been sold by the Babcock & Wil- cox Company to the Bath Iron Works Cor- poration, Bath, Maine for the States Steamship

Company, San Francisco, Calif.

B&W's "zero discharge" Sanitary Waste

Disposal system (SWD), the first of its kind to be sold, will be installed with B&W marine boilers on three new 18,000-ton roll-on/roll-off type ships scheduled for commercial operation during 1974. The total contract amounts to $2.1 million.

According to R.E. Whitam, B&W manager of marine marketing: "This type of system is an advancement over the present practice of chemically treating waste and discharging it overboard. Because of its unique nature in in- cinerating the effluent in the ship's propulsion systems," he added, "no liquids are discharged overboard."

The SWD system has been undergoing test- ing for two years at B&W's Alliance, Ohio Re- search Center. Based on test results, it will meet Environmental Protection Agency stand- ards regulating marine sources of pollution.

The B&W Sanitary Waste Disposal system utilizes the main propulsion boilers to inciner- ate sewage 'from the vessel's sanitary system, laundry washwater and galley garbage disposal.

The SWD system consists of a holding tank where waste is chlorinated and aerated, a pump grinder, and a mechanism for firing the waste into the boiler. Once in the boiler furnace, the liquid is evaporated and the waste is burned, converting it into steam and a biologically in- ert gas.

Because of its simplicity and few number of moving parts, it can be installed on new ships or retrofitted to existing boilers. The system requires little maintenance and is designed for completely automated operation.

The size of each system varies according to the specific needs of the ship so that the hold- ing tank can handle approximately one and a half days of accumulation. The systems design- ed for the new States Steamship Company ves- sels will handle 70 gallons of sewage per man/ per day, and is based on a capacity of 55 people.

Mr. Whitam stated that the system has been designed to operate on ships using freshwater sanitary systems, as in the case of most mod- ern vessels. "The conversion," he said, "of ex- isting saltwater systems to fresh water is rela- tively a simple task, and would involve an amount equal to approximately 30 gallons of fresh water per day/per man."

Commenting on the SWD system's market- ing potential, Mr. Whitam concluded that: "As the stringent environmental laws governing shipboard dumping come into effect, our sys- tem looks like the answer for the future in shipboard waste disposal for steam-propelled ships."
