Crowley's Vessel Management Services subsidiary
signed a contract with VT Halter Marine Inc. to build another four articulated tug-barge (ATB), 185,000-barrel tank vessels
. The new contract, which includes owner-furnished equipment, is valued at $190
million. Total construction time for all four vessels is 36 months.
ATBs will be delivered to and put into service by Crowley's newly formed
Petroleum Services segment as they are completed. Two similar 185,000-barrel
ATBs are already under construction for Crowley at VT Halter's facilities in
Mississippi and are scheduled for delivery to Crowley in the first and third
quarters of 2006. They will join four 155,000-barrel ATBs already in service
on the U.S. West Coast. By 2008, Crowley will have 10 ATBs serving customers
in the U.S. coastwise petroleum trades.
The ATB currently under construction and scheduled for delivery in the first
quarter has already been chartered to ConocoPhillips under a three-year
agreement reached earlier this year.
"This is yet another example of our commitment to invest in new equipment
and technology to meet the current and future needs of our customers," said
Tom Crowley Jr., company chairman, president and CEO. "We are bringing the
best available technology to our customers who understand and appreciate
safety and operational excellence.
These new vessels will provide
reliability, cargo flexibility and environmental protection."
An ATB has an articulated, or hinged, connection system between the tug and
barge, which allows movement in one axis or plane in the critical area of
fore and aft pitch. The four tugs being built under the new contract will be
interchangeable with all vessels in the Company's ATB fleet. The
185,000-barrel barges will be substantially identical to those currently
The new ATBs feature
the latest systems technology and double-hull
construction for maximum safety and reliability. Not only does the unit have
the capability of transporting refined products, but it can also carry
heated cargoes and easy chemicals, which require special arrangements of
vents, stripping systems, pump components and tank coatings not required of
All of Crowley's ATBs are built under the ABS SafeHull program for
environmental protection. This program puts the vessel design through an
exhaustive review to identify structural loads and strengthen the vessel
structure. The 650-Class barges will be 27,000 deadweight tons, 587 feet in
length, 74 feet in breadth and 40 feet in depth. The fully loaded draft will
be 30 feet.
There is an electric cargo pump in each of the 14 cargo tanks to assure
maximum cargo integrity and segregation flexibility; two anchor windlasses
and associated equipment to enable the vessel to accommodate offshore
mooring operations, and a vacuum system with three retention tanks to easily
handle cargo changes. There is also a dual mode inert gas system and vapor
collection system for maximum safety. A layer of inert gas covers
in the tanks to make the atmosphere too lean for combustion. An enhanced
mooring system features 1,000-foot Spectra-type lines on split drums with a
high-speed recovery rate of 100 feet per minute.
The tugs meet all SOLAS (Safety of Life at Sea) and ABS criteria, and have a
foam capable fire monitor; twin fuel-efficient diesel engines; a noise
reduction package and other upgrades to increase crew comfort. The
communication and navigation equipment
is among the most technologically
advanced in the industry today.
