The Chesapeake Section of The Society of
Naval Architects and Marine Engineers held
the fourth meeting of its 1972-73 technical pro-
gram on January 11, 1973, at the Naval Medi-
cal Center Officers Club in Bethesda, Md.
Following the social hour and dinner, which
were enjoyed by approximately 150 members
and guests, vice chairman Seth Hawkins open-
ed the meeting by welcoming those in atten-
dance and congratulating William Hunley,
chairman, membership committee, for his role
in recruiting 139 new members and 59 upgrad-
ings in membership during the past year.
Vice chairman Hawkins also introduced the
national president of SNAME, Phillip Eisen-
berg, who was in attendance.
After completing other normal Section busi-
ness, vice chairman Hawkins introduced the
moderator of the technical session, E. Scott
Dillon, Assistant Administrator for Operations,
Maritime Administration. Because of the tur-
moil surrounding both the need to import oil
during the energy crisis and the Government's
pollution abatement program, Mr. Dillon in-
troduced this paper as a "painfully timely pa-
per." He introduced the authors as representa-
tives of a Government/industry team establish-
ed to study one phase of this problem. The
authors are: Peter M. Kimon, head, research
tanker department, ESSO International Divi-
sion, EXXON Corp.; Ronald K. Kiss, Chief,
Division of Ship Design, MarAd, and Lt.
Comdr. Joseph Porricelli, MMT, USCG, and
the title of their technical paper was "Segre-
gated Ballast VLCCs—An Economic and Pol-
lution Abatement Analysis."
The technical discussion of the paper was
Roland Verret Joins
Scully Brothers Boat
Roland Verret, formerly with the Central of
Georgia Railroad, Macon, Ga., has been named
general office manager of Scully Brothers Boat
Builders, Inc., Morgan City, La., Raymond
Scully Jr., president, reports. A graduate of
Iowa Institute of Telegraphy, Marshalltown,
Iowa, Mr. Verret was with Petroleum Heli-
copters in Morgan City before joining Scully
Brothers, where he will be in charge of per-
sonnel, payroll, accounting and purchasing.
Scully Brothers reports that it currently has
contracts for eight shrimp boats, two towboats
for Big T Marine Towing and Sales, and one
towboat for Wisconsin Barge Line. The Big T
boats measure 75 feet by 30 feet by 10 feet, and
presented in two parts, one by Commander
Porricelli, and the other by Mr. Kiss. The pa-
per presented the results of a study of very
large crude carriers (VLCCs) to determine the
cost and effectiveness of variations in the ca-
pacity of segregated ballast in these tankers
and several variations in tank arrangements
to reduce oil pollution due to operational and
accidental causes. The tank arrangements con-
sidered were double bottoms, double sides,
double skins and alternating cargo and ballast
wing tanks. The paper concentrated on a series
of 250,000-dwt tankers, but did also consider
the influence of ship size by including results
for tankers of 120,000 dwt and 477,000 dwt.
The degree of effectiveness for each tank ar-
rangement was estimated for both operational
and accidental pollution based on the best
available data. Sensitivity studies were pro-
vided to verify the general conclusions of the
report. Finally, estimates of the cost to pre-
vent one cubic meter of oil pollution were pre-
sented for each of the various design arrange-
ments.
Written discussions were presented by Lt.
Comdr. Virgil Keith, USCG; Captain Dickson
(read by Captain Van Lier), Shell Oil Co.;
M. de Leon, J.J. McMullen Assoc.; Lee Parke
Adair, J.J. Henry Co., and R. Granville Parker,
Bethlehem Steel. The authors' closure and an-
swers to both the written and verbal discus-
sions were presented by Mr. Kimon.
The obvious interest of the membership and
the discussions generated by this paper in-
dicated that the final solution has yet to be
determined and will be the subject of future
analysis and debate.
58 feet by 22 feet by 8 feet. The larger boat
will be equipped with two Brons diesel engines
supplied by Oosterhuis Industries, Inc. The
small vessel will have a stilted pilothouse.
The Wisconsin Barge Line vessel measures
65 feet by 24 feet by 8.6 feet, and will be de-
livered in early spring. Also, an offshore supply
vessel was recently built and launched for Joe
Galloway of Morgan City. Named the Star
Buck, this vessel measures 100 feet by 26 feet
by 10.5 feet.
'Scully Brothers is currently expanding its
facilities for prefabrication of pilothouses and
storage of steel. A new warehouse with a stock-
room and two offices for foremen is also under
construction, and the main office has been re-
located and enlarged to accommodate increased
production expected in 1973.
Seaspan International Ltd. has recently com-
menced a new tanker-barge service with a new-
ly constructed 25,500-barrel-capacity vessel.
Designed by Cove Hatfield and Company
and built by Vancouver Shipyards Co. Ltd.,
the Seaspan 822 has dimensions of 240 feet by
54 feet by 16.6 feet and a mean draft of 12 feet
6 inches in the loaded condition. It contains 18
separate tanks with four pumping systems that
can be used in tandem. In addition, i-t is equip-
ped with a crane and storage areas for handling
drum and packaged cargo. Antipollution con-
trols are included in the barge equipment.
Following the trend of the more recent Sea-
span barges, the vessel is not fitted with hull
guards but has a heavy 5/8-inch side shell with
suitable internal stiffening. The boarding lad-
ders are recessed to give an overall sleek ex-
terior appearance.
This addition to Seaspan's fleet will enable
the company to fulfill a recently signed con-
tract with Standard Oil Company of B.C. Ltd.
covering transportation services on the British
Columbia coast.

SNAME EASTERN CANADIAN SECTION MEETS: In fol-
lowing with the adopted policy of the Eastern Canadian
Section of The Society of Naval Architects and Marine
Engineers to hold a number of meetings outside of the
Montreal area, the January 25 meeting was convened in
Ottawa. Sidney Mathews, area vice chairman, presided.
The guest speaker, Lt. Comdr. R.C. Smith of the Canadi-
an Armed Forces, presented a paper titled "Developing
a Canadian Undersea Capability," outlining the economic
technological relationship which would be likely to occur
in an undersea exploratory program. Following the paper,
a lively discussion from the floor ensued, indicating a
very high degree of interest by the members and guests
in the topic discussed in the paper. Pictured at the meet-
ing, left to right, are: R.C. Truax, chairman of the East-
ern Canadian Section, Commander Smith, author, and
