The offshore supply vessel 'Doc Tide' after conversion by Bender Shipbuilding.
Bender Shipbuilding Converts
Two Offshore Supply Vessels
For Tidewater Marine
Bender Shipbuilding & Repair
Co., Inc. of Mobile, Ala., recently re-
delivered two offshore supply ves-
sels to Tidewater Marine Services,
Inc., New Orleans, La., after com-
pleting extensive conversions.
The Doc Tide and Darol Tide
were lengthened by 16 feet to ac-
commodate liquid mud tanks and
chain lockers, making the new over-
all length 216 feet.
Both vessels are equipped with a
more efficient, 55-inch diameter
Bird-Johnson 35/3S/FP bow thrust-
er which develops 16,050 pounds of
thrust; a Fritz Culver releasable ca-
ble stop; and a GM 4V71 diesel
engine which was added to drive the
four Mission Viking liquid mud
pumps. Each pump can transfer 850
barrels per hour. Bender also car-
ried out routine drydocking and re-
pairs on the two vessels.
Tidewater Marine Service, Inc., a
division of Tidewater Inc., operates
one of the world's largest offshore
service fleets.
Aside from its well-known new
construction capabilities, Bender
Shipbuilding & Repair is a leading
ship repair facility on the Gulf
Coast with three floating drydocks
of up to 18,000 tons of lifting capac-
ity.

Fuel Management Systems
Lease Program Introduced
By DiFlo International
DiFlo International recently an-
nounced that the company is intro-
ducing a monthly lease program for
its Series 1000 Fuel Management
Systems as an alternative to an out-
right purchase, according to Thom-
as E. Prosser, DiFlo president.
Available to financially qualified
operators of vessels and fleets in the
inland waterways and offshore, the
leasing program has been designed
to eliminate the initial outlay of
capital for the purchase of the
equipment and to allow the operator
to immediately lower operating ex-
penses from lower fuel costs.
The lease can be structured up to
36 months, depending on the cus-
tomer's needs, with an option to
purchase the system for a small per-
centage of the original purchase
price. Depending on its tax struc-
ture, the customer may also choose
to take advantage of the Investment
Tax Credit with the lease. Installa-
tion of the system and training of
key wheelhouse/bridge personnel is
also included in the DiFlo Lease
Program.
"Based upon savings documented
by customers currently using the
Series 1000, and combined with an
estimated daily lease cost in the $13
to $15 range, we believe that an
operator can gain the advantage of a
10 to 30 percent fuel savings," Mr.
Prosser stated. "Depending on the
daily fuel costs for a vessel, the daily
accumulation of these savings can
be very attractive to fleet managers
working in a competitive industry
currently characterized by signs of
slow growth in the short term," he
added.
"In addition to the direct benefits
associated with lower fuel costs.
operators have experienced reduced
expenditures for lubricants and
maintenance when they find they
can run their engines at the lower
rpm indicated by the DiFlo Sys-
tem," Mr. Prosser concluded.
DiFlo International, Inc., from its
headquarters in Houston, Texas,
designs, manufactures, markets and
installs a line of computer-based
fuel management systems for inter-
nal combustion engines fueled by
diesel or natural gas in the marine,
and oil and gas and transportation
industries throughout the United
States and internationally.

Flo's new leasing program for its

New Control Valve
By Pittsburgh Brass
—Literature Available
Pittsburgh Brass Manufacturing,
Irwin, Pa., has introduced the pres-
sure logic valve, a new concept in
directional control for fluids, gases
and air.
The operating principle incorpo-
rates a unique "sliding stopple" that
logically shuttles back and forth to
direct media flow. With its short
travel stroke, motivated by low cost
air pressure, (20 psi max) thousands
of cycles have been accomplished
without any sign of wear.
These full port valves reduce the
cost of a piping system, with one
P.L.V. taking the place of two 2-way
valves and in some cases a more
costly three or four way multi-port
valve with a standard actuator.
Available in % through 4-inch
sizes with screwed, grooved or
flanged ends.

sure logic valve,
