The Calhoun LNG Project under development at
The Port of Port Lavaca – Point Comfort will be designed, constructed, and permitted
for a capacity of regasifying
up to 1 Billion cubic feet (Bcf)
of natural gas per day. The terminal
facility will be located on a
remote piece of Port property
fronting on the Matagorda Ship
Channel. The project has several strategic advantages compared to other
proposed LNG projects in North
America such as existing deepwater
port and facilities infrastructure,
strong support of the Port Authority,
interest from large industrial users in the area, and nearby
access to gas pipelines. Provided
below is a brief description
of the technical aspects of
the Project.
Marine
Facilities
The berthing facility will be structurally designed to handle a variety of LNG tanker
sizes and designs. The unloading dock will be equipped with three 16” diameter articulated
LNG unloading arms and one 16” diameter articulated vapor return arm. Each arm will
be equipped with emergency shut-down systems to minimize the possibility of a spill during
unloading
operations. Construction of the marine facility will
require some dredging along the property and the turning basin.
Storage Tanks
The storage facilities will consist of two storage
tanks with each tank capable of storing 160,000 cubic meters (5.7 million cubic feet)
of LNG at a temperature of minus 260 degrees Fahrenheit. The inner tank will be fabricated
from 9% nickel steel plate, aluminum hanging roof plate, further enclosed by a carbon
steel outer tank and roof. Specialty insulation will fill the annular space between the
inner and outer tank, and blankets the internally suspended roof plate. The tank will
be constructed on a pile-supported concrete cap and will be situated inside a dike capable
of containing 110% of its full contents.
Vaporization and
Separation
The vaporization and separation system will consist
of LNG transfer pumps, vaporizers and a re-condenser/separation system necessary to warm
LNG back into a gaseous state to meet natural gas pipeline quality specifications for Natural
Gas. The Facility will be designed to separate natural gas liquids (NGL’s) from the
LNG thus allowing the Terminal to take higher Btu LNG which provides added benefits to
potential industrial end-users and conformity of natural gas to meet the stringent pipeline
specifications of the natural gas pipelines.
Utilities
The Terminal will tie into and utilize existing
Port utilities such as power, water, waste water and fire protection systems. Supplementary
infrastructure will be installed as required including a dedicated and self-contained
fire detection and emergency system within the Facility. A central control center and
administration building will be constructed within the facility, and tied into the exiting
port control room.
Interconnecting
Pipelines
The pipeline connecting to the Calhoun LNG terminal
and delivering the natural gas to the local markets
and major pipelines in the region will be owned
and operated by Point Comfort Pipeline Company, L.P., an affiliate of Gulf Coast
LNG Partners, L.P. The natural gas pipeline will
consist of 27 miles of 36-inch pipeline designed
to transport one billion cubic feet (Bcf) per day of natural gas from the LNG
terminal. The pipeline will be able to access
approximately 5 Bcf per day of pipeline takeaway capacity, allowing
it to reach two-thirds of the natural gas consumers in the U.S. as well as Northern
Mexico. The planned pipeline connections include Energy Transfer (Houston Pipe Line/Channel System), Florida Gas Transmission, Kinder Morgan (Texas and Tejas Systems), Enterprise (Valero and Channel Systems), Boardwalk (Gulf South System), Natural Gas Pipeline of America, Transcontinental, and Tennessee Gas.
Permitting
The permitting process for LNG terminals is led
by the Federal Energy Regulatory Commission
(FERC) and also involves numerous other
state and federal agencies such as the Texas Commission of Environmental Quality (TCEQ),
the
Coast Guard and the U.S. Army Corps of
Engineers.

the FERC permitting process can

Project
Schedule
The
project schedule can be divided into two phases,
permitting and construction. The permitting phase
is expected to last between 12 and 18 months.
The construction phase will commence once all
permits and necessary commercial contracts have
been secured. Once underway, construction of the facility will take
approximately 3 years. The Facility could be
operational in late 2009 or early 2010.
