President Reagan And Sponsor
Authenticate Keel Of 'Yorktown' At Ingalls
As part of his participation in
the bicentennial celebration of
the Battle of Yorktown, Va., that
ended the Revolutionary War,
President Reagan authorized the
start of hull construction on a
new U.S. Navy cruiser to be
named Yorktown (CG 48). In the
upper photo, the President and
Secretary of the Navy John F.
Lehman look on as Mrs. Mary
Mathews, sponsor of the Aegis
guided missile cruiser, initials a
plaque that will become a perma-
nent part of the ship. The Presi-
dent also initialed the plaque,
which authenticates the keel-lay-
ing of the second ship in the
Ticonderoga Class. Prior to the
ceremony at Yorktown, employ-
ees of Ingalls Shipbuilding Divi-
sion of Litton Industries in Pas-
cagoula, Miss., the builder of the
ship, positioned the first hull sec-
tion or "keel" onto its blocks,
signifying the beginning of con-
struction.
Marathon Launches Jackup
Penrod 86 At Brownsville Yard
These four frames capture the
launch sequence of the Penrod 86,
a class 82-SD-C self-elevating off-
shore jackup drilling platform
built by Marathon Manufactur-
ing Company, Houston, Texas.
The shallow-draft cantilever
drilling unit was launched re-
cently at Marathon's Gulf Marine
Division yard in Brownsville, Tex-
as. The rig is rated for water
depths up to 250 feet. When the
remaining sections of its three
triangular legs are added, thev
will be 360 feet tall. The derrick
and other drilling components
have yet to be installed. The rig's
cantilever design lets the derrick
move out beyond the stern so
that the rig can work next to
permanent offshore platforms
without putting the weight of the
drilling package on these plat-
forms.
Halter Delivers
New Offshore Express Supply Boat
Built by Halter, the 166-foot
Cameron Express (shown above)
is operated by Offshore Express,
Inc. of Houma, La., for Mesa Pe-
troleum of Freeport, Texas.
The first of three 166-foot liq-
uid mud supply boats for the com-
pany, the Cameron Express is one
of seven new vessels added or be-
ing added to the Houma-based
Offshore Express fleet in a recent-
ly announced $16-million expan-
sion program. The others are the
Cameron 166-foot supply boats
Breton and Chandeleur Express;
the 102-foot crewboat Lightning
Express, already in service; two
115-foot utility boats, and a 180-
foot supply vessel. The latter is
scheduled for delivery in Decem-
ber. The others were delivered in
the fall.
Built by Halter Marine at its
Calumet yard for Shearson Equip-
ment Investors of New York, a
limited partnership, the Cameron
Express is one of the largest in
Offshore Express's 16-vessel fleet,
which range from 80- and 102
foot crewboats and 110-foot util-
ities, to the 187-foot supply boat
Trojan Express.
The Cameron Express provides
below-deck storage of 1,900 bar-
rels of liquid mud for delivery to
the drilling platform. It also is
equipped with four 750 Pneu-
tanks for storage of dry mud. It
is powered by 16-149 Detroit Die-
sels delivering 2,000 hp, has deck
cargo space for 500 tons, and a
cruising speed of 12 knots. The
deck size of the Cameron Express
is 118 by 29.
"This is a significant new ad-
dition to our growing fleet," com-
mented Robert C. Schmidt, vice
president and general manager of
Offshore Express. He said the
company has long had a policy of
acquiring vessels tailored to the
specific needs of its customers
and "the Cameron Express exem-
plifies that policy. She is designed
for extreme stability in rough
seas, for speed and maneuver-
ability as well as for maximum
storage facilities," he said.
New Compact Oil Water
Separator From Sigma
—Literature Available
Sigma Treatment Systems, Inc.,
Chester Springs, Pa., is offering
literature on a new addition to its
line of marine pollution control
equipment. The SH2 Oily Water
Separator is U.S. Coast Guard cer-
tified and meets IMCO standards.
Designed with simplicity and
minimum maintenance in mind,
the single-tank units are fully
automatic devices with only one
pump. No disposable cartridges
or other consumables are used.
Permanent coalescer beds are au-
tomatically backwashed every
time separated oil is discharged.
Failsafe operation is ensured by
the addition of an optional mon-
itor which activates an automatic
recirculate valve and an alarm
system when oily content of the
effluent exceeds 15 ppm. Addi-
tional features of the monitor in-
clude outputs for continuous mon-
itoring and remote alarms. The
SH2 OWS is available in standard
capacities from 2-50 gpm through
Sigma's worldwide distribution
network.
