Hellenic Yards To Build 300,000-Ton Graving Dock —Six 300,000-Dwt Tankers

Hellenic Shipyards Company, Skaramanga,

Greece, has announced a contract to add a 300,- 000-ton graving dock to its already extensive facilities. In addition, orders to build six 300,000- deadweight-ton tankers have already been re- ceived.

The dock will be completed in two, to two and one-half years. However, prefabrication will enable the ship construction in the dock to pro- ceed rapidly thereafter.

The announcement was made at the launching at the yard's 21st SD-14 cargoship of 15,000-dwt.

Six similar ships, of liner configuration, are under construction, as well as seven 35,000-dwt bulk carriers and five 30,000-dwt product carrying tankers.

Hellenic Shipyards was started in 1956 in a country with little industrial activity and has become one of the leading Mediterranean yards in ship repair, which continues to be a major activity. It has three floating drydocks, with ca- pacities up to 72,000-dwt, and a 250,000-dwt grav- ing dock, temporarily used for new construction.

Another Greek marine project being under- taken by the Niarchos Group is the construction of a diesel engine factory and associated with it,

Greece's largest iron foundry. Grand Motori, a subsidiary of Fiat and the Italian Government's

IRI, will participate in the diesel factory.

These marine projects are part of a 1970 under- taking by the Niarchos Group with the Greek

Government, which also includes major ex- pansion of oil refining facilities and a new aluminum plant for a total investment of more than $200,000,000.

Texaco Contracts For

Two Drilling Barges

Texaco Inc. has announced that it is entering into long-term contracts for two new semisub- mersible drilling barges, primarily for use in the

United Kingdom and other waters of the North

Sea.

Texaco said that these drilling barges will be capable of drilling in offshore areas anywhere in the world. One will be built and operated by

Storm Drilling Co., Houston, Texas, and the other by Sedco, Inc., Dallas, Texas.

The first unit, scheduled for delivery in Feb- ruary 1973, will be built by Storm in a U.S.

Gulf Coast shipyard. The second unit, known as type 701, is to be delivered in the fall of 1973 and will be built by Sedco in the Hawker-

Siddeley shipyards at Halifax, Nova Scotia.

NEW LANDMARK: Artist's conception shows how sub- marine building ways at Electric Boat Division of General

Dynamics, Groton, Conn., will appear after they have been enclosed. Berlin Construction Co., Berlin, Conn., has begun work on the enclosure, which will provide an im- proved year-round environment for production employees.

The ways, 502-feet long and 1 86-feet wide, tower 140 feet above the Thames River. The shipyard development project will also include additional lighting and will not interfere with submarine construction currently under way. Four nuclear powered subs can be built within the structure.

COMPLETE, FLEXIBLE FULLY AUTOMATIC DIAL TELEPHONE

SYSTEMS ENGINEERED FOR SHIPBOARD COMMUNICATIONS

Larger vessels, smaller crews and increased efficiency have created a need for a more flexible communications system to supplement sound powered telephones. Hose-McCann— pioneers in the introduction and development of sound powered telephones for marine use —provides the perfect answer with AUTOMATIC DIAL TELEPHONE SYSTEMS. Expandable systems available in 20, 40 and 100 line capacities. Larger systems available and engineered to meet your special requirements.

EXCLUSIVE HOSE-McCANN FEATURES

PLUG-IN TRAYS: Insure trouble-free operation and minimum maintenance. Identical and interchangeable, can be replaced instantly.

COMPONENTS: All electro-mechanical parts for the operation of the switchboard are located on the Plug-In Trays. All contacts self cleaning.

MarAd Awards Curtiss-Wright

Contract To Develop Marine

Power Transmission Systems

The Power Systems Group of the Curtiss-

Wright Corporation, Wood-Ridge, N.J., has 'been awarded a multimillion dollar two-phase development contract by the Maritime Admin- istration (MarAd) to develop marine planetary gear transmission systems, it was announced by Leonard Schatz, director of the Curtiss-

Wright Group.

The aim of the MarAd project is to develop a family of transmission systems capitalizing on the advantages of planetary gears over re- duction gears currently in use. The epicyclic's compact, readily reversible, modular form make it attractive for a wide variety of ship types and sizes, particularly when combined with gas turbine prime movers.

The first phase of the contract is a one-year program funded by MarAd at a cost of $950,- 000 to design and detail two planetary mod- ules.

The second phase, funded jointly by MarAd and Curtiss-Wright, will include fabrication and prototype testing. This portion is esti- mated to cost $6 million and require about three years.

Two types of systems are to be developed leading to a family of derivative reduction gear modules satisfying the needs of merchant ves- sels for 15,000 horsepower to 75,000 horse- power per shaft.

The first system to be developed is a two- stage planetary with reversing capability; the second is a two-stage planetary with reversing and contra-rotating output shafts.

Mr. Schatz emphasized that this work rep- resents a continuation of effort to apply exist- ing aerospace technology to industrial, marine and power generation markets.
