Liberia And Japan Continue

Lead In Sun Oil Co/s 29th

Annual Tank Ship Survey

For the 14th consecutive year, Liberia with 24.7 percent, led the world in total carrying capacity of tank ships registered, according to the 29th

Annual World Tank Ship Survey recently issued by Sun Oil Company.

Japan again led for the year 1970 in construc- tion of new tankers, a lead position she has main- tained for all but one year since 1956. The United

States remained fifth in world carrying capacity in 1970 and retained 11th place in tanker con- struction.

The Sun Oil survey reports that the world tank ship fleet on December 31, 1970 was 14.2 percent larger in deadweight tonnage than a year earlier, with 3,994 vessels of 2,000 gross tons or more totaling 166,744,000 deadweight tons. The fleet increased by 101 vessels and by 20,745,000 dwt.

In terms of carrying capacity, United Kingdom,

Norway and Japan occupied second, third and fourth places respectively, with the United States in fifth place. Greece and Panama were sixth and seventh leading flags of registry. France was eighth, followed by Italy, U.S.S.R., Sweden and the Netherlands.

Japan had 32.1 percent of the total world tanker tonnage under construction in her shipyards, total- ing 24,248,000-dwt., to maintain her lead in new ship construction. Sweden, France, Denmark,

Spain and Norway followed in descending order.

Western Germany retained seventh place, while the Netherlands rose from 10th to eighth position.

The U.S. had at year's end, 21 tankers totaling 1,873,000 dwt under construction.

During 1970, there were 213 tankers delivered into the world fleet, while 125 vessels were scrap- ped. Transfers between flags totaled 148 vessels.

The average deadweight tonnage of oceangoing tank ships of 2,000 gross tons or more increased from 37,500 dwt a year earlier to 41,800 dwt. The average speed remained at 15.8 knots.

Japanese flag tankers continued as the newest among major flags of registry, with an average age of four years two months at the end of 1970.

The U.S.-flag tanker fleet was the oldest, averag- ing 16 years, five months.

At the end of the year, there were 649 tank ships of 2,000 gross tons or more representing 75,447,000 dwt on order or under construction in the world's shipyards, an increase from the year before of 79 vessels and 16,119,000 dwt. The average vessel under construction increased in size to 116,300 dwt from 104,100 dwt a year earlier.

Iotron Conducts Vessel

Collision Avoidance Seminar

Iotron Corporation of Bedford, Mass., recently conducted a collision avoidance seminar at the

Showboat Motor Inn, Greenwich, Conn. Capt.

H.E. Van der Linde, president of Transportation

Concepts and Techniques, sponsored the seminar to inform both administrative and technical man- agement of the shipping industry on recent ad- vancements made in marine collision avoidance equipment. A seagoing demonstration of the latest production model of Digiplot® was given aboard

Tradewinds, Iotron's test vessel, and Long Island

Sound provided an excellent setting for proving the benefits of Digiplot in congested waters.

Representatives from the following organiza- tions were present: American Bureau of Shipping,

ARCO, Continental Oil Co., Gulf Oil Corp.,

Island Navigation, Liberian Services, Lykes Bros.

Steamship Co., Marcona Corp., Mobil Oil Corp.,

Moller Steamship Co., National Bulk Carriers,

Olympic Steamship Co., Sea-Land Service Inc.,,

Southern Star Shipping Co., Texaco Inc., J.P.

Tilden Ltd., Transoceanic Marine Inc., Triton

Shipping Inc. and Victory Carriers Inc.

Presentations were given which traced the evolution of various types of radar navigational aids, including a summary of current techniques and systems intended to minimize the risk of collision. John C. Herther, Iotron president and seminar chairman, introduced Digiplot, his com- pany's fully automatic radar plotter. Mr. Herther stated that Digiplot is the most advanced system in operation today.

Navigation, listening to a question during the demonstra- tion. John C. Herther, president of Iotron (far right), demonstrates the Digiplot aboard the Tradewinds.

The Digiplot unit will analyze 200 objects on the water within 12 miles and automatically dis- play the 40 most threatening. It also displays the shoreline on the scope with dotted lines.

Each object on the Digiplot scope is represented by a single white dot. Emanating from each white dot is a white line showing the course that the ship in question will travel in so many minutes.

The desired number of minutes is set by a control on the console. The computer, memorizing past movements of the ships, generates the course lines in a flash. If there is no white line from a white dot, it indicates that the object is a buoy or a stationary target.

Among other features of the Digiplot were meters showing the closest distance that the ship using it would come to any selected other "target" and the time till that closest approach, audible and visible alarms, and devices to produce indications on the scope of how a certain course change would affect the traffic situation.

Mr. Herther states that Iotron is now in pro- duction and that the company had received orders for 18 Digiplot units from vessel operating com- panies.
