munications Technology Joint Re- search and Development Project.

The project is sponsored by the

Council of American-Flag Ship

Operators (CASO) as part of the

Maritime Administration's fleet management technology program.

ARINC Research Corp. of An- napolis, Md., is a subcontractor to CASO on the project.

One of the project's objectives has been to establish a reliable, inexpensive, medium-speed data connection between ships and their home offices using INMAR-

SAT'S satellites, ships equipped with satellite antennae, and pub- lic switched telephone lines.

Issues Call For Papers

Two GM Detroit Diesel engines will supply the main propulsion for the new dredge and another two Detroit Diesels will power the drag arms. Maritime Industries Ltd. of Canada supplied two Z-drive steerable propellers and a new thruster.

New Ferry Contract For

Over $1-Million Awarded

To Offshore Shipbuilding

The North Carolina Depart- ment of Transportation has awarded a contract "in excess of a million dollars" to Offshore

Shipbuilding of Palatka, Fla., for the construction of a 250-passen- ger/vehicle ferry.

The contract is the second for a ferry awarded to Offshore Ship- building since October 1982, when the firm launched construction on a $4.5 million, 1,200-passenger "cruise ship" ferry for service in the State of New York.

Anthony M. Tenore, vice pres- dent and general manager of Off- shore Shipbuilding, said his yard was low bidder among "25 major shipyards" that wanted the North

Carolina ferry job.

The vessel will be of standard design by the North Carolina

Department of Transportation,

Ferry Division, with detail work by Bold Craft Engineering of

Jacksonville, Fla. The design calls for an open vehicle deck extend- ing the length of the ferry with two 40-foot passenger cabins lo- cated amidships on both sides. An overhead deck spanning the two cabins will accommodate the pi- lothouse.

Overall length will be 129.6 feet, with a beam of 40 feet, and a 9-foot depth to make the ferry serviceable in various rivers and sounds in North Carolina. Load- ing and offloading will be possi- ble at both ends but unlike stand- ard double-ender ferries, the ves- sel will have propulsion at only one end in the form of twin

Caterpillar 3412 diesels.

Mr. Tenore said construction will begin early in January with delivery scheduled for April of 1984.

Lykes Ship Sends Data

By Satellite-Phone Hookup

Lykes Bros. Steamship Co.,

Inc., New Orleans, La., recently demonstrated a reliable, inexpen- sive method of transmitting data at medium speed from ship to shore via satellite and regular telephone lines.

Lykes made repeated transmis- sions between one of its ships, the Cygnus, and shore on a re- cent voyage as part of a Mari- time Administration-sponsored program. Lykes is the first com- pany to participate in such a sat- ellite-telephone ship data trans- mission for which technical re- sults are being published.

The ship-shore data communi- cation can be used to transmit cargo and payroll information and vessel performance infor- mation.

Two Lykes ships, the Cygnus and the Lyra, are participating in the Advanced Maritime Com-

The Marine Technology Soci- ety (MTS) and the Institute of

Electrical and Electronic Engi- neers (IEEE) Council on Oceanic

Engineering (COE) have invited papers from all interested au- thors for the Oceans '83 Confer- ence and Exposition.

Each accepted paper will be presented at the conference in

San Francisco, Calif., which will be held at the Hilton Hotel,

August 29-September 1, 1983. All accepted papers will be published in the Proceedings and mailed to the participants at the conclusion of the conference. Deadline for the receipt of abstracts of the papers is Feb. 11, 1983.

The theme of Oceans '83, "Ef- fective Use of the Sea — An Up- date," underscores the objectives of marine science and technology to explore, conquer, develop, and utilize ocean resources for the benefit of mankind. The goal of the conference will be to identify current and future technology, knowledge, and programs needed to achieve these objectives by the year 2000.

Papers are requested which highlight technological advances in the understanding, use, and recovery of marine resources, and identify and/or suggest oth- er technologies that could be used to advance marine science and engineering.

Oceans '83 will be international in scope and will focus on the science and technology required for the utilization of five major ocean resource areas: mineral re- sources and energy; non-mineral resources; transportation; ocean science; and military ocean engi- neering. The emphasis in each of these areas will be on technolo- gies, technology assessment, ap- plication, and programs. Papers that address other important de- velopments applicable to marine science and technology will also receive consideration.

Work commenced at Nichols

Brothers Boat Builders, Inc.

Whidbey Island yard, Freeland,

Wash., recently on the initial phase of a 265-foot by 54-foot by 22-foot self-propelled trailing suc- tion split-hull hopper dredge.

Manson Construction & Engi- neering Company of Seattle,

Wash., is the customer for this unusual work vessel.

The hull is made up of two longitudinal half sections hinged together at the deck. This split- hull concept was conceived before the year 1900 and has been used primarily in dump barges. Man- son's new dredge, provisionally named Newport, being self-pro- pelled, will be a new departure from their traditionally tug- assisted barges.

Through this design, Robert

Presents Paper At SNAME

New England Meeting

The recent meeting of The So- ciety of Naval Architects and

Marine Engineers, New England section, held at the New Eng- land Aquarium, Central Wharf,

Boston, Mass., featured the pres- entation of a technical paper en- titled "Marine Installation and

Operating Requirements for Con- tinuous Electric Liquid-Level

Gauging Equipment."

The paper was delivered by

Albert D. Ehrenfried, founder and president of Meritape, Inc. of Concord, Mass. The author first presented an overview of the liquid-level gauging requirement for a wide range of marine float- with a vessel capable of dredging mud and sand to a depth of 65 feet. Hopper capacity is 4,000 cubic yards. The drag arms are operated by two Detroit Diesel 16V149 diesel engines and two additional Detroit 16V149s will propel the dredge at a speed of 10 knots with a light load and 8 knots when loaded.

The propulsion system, featur- ing two "Z" drive steerable pro- pellers and a bow thruster, is from Maritime Industries Ltd.,

Vancouver, B.C. The 18-man crew will be comfortably housed in a centrally heated and air- conditioned deckhouse.

When the first phase has been completed in March 1983, then construction of the superstruc- ture, wheelhouse, and living quar- ters will follow, with total com- pletion due in May 1983. ing structures, including tankers, drydocks, drill rigs, and military vessels. Applications he described included the accurate determina- tion of cargo, ballast, and fuel oil levels; the measurement of ship's draft, trim/list, hog/sag; and the quantification of com- partment flooding for naval dam- age control.

The principles and performance characteristics of electric dis- tributed-resistance level gauging equipment developed by the au- thor were then set forth, along with current practices for inte- grating such gauging into the hull structure. Human factors re- lating to the equipment, includ- ing training for familiarization, calibrating procedures, and trou- ble-shooting, were also discussed.
