Increasing Demand for Regas - How Large
Does Exmar See the Regas Fleet Growing Jay
Cotaya, Exmar Offshore Company Exmar confirmed
a long-term charter in
December 2005 with
Excelerate Energy LP for a fifth LNG regasification
vessel (LNGRV) to be built by Daewoo Shipbuilding
& Marine Engineering Co. Ltd (DSME). This
vessel will incorporate the GTT membrane
containment system together with Excelerate's
Energy Bridge™ technology. The ship will
have a capacity of approximately 150,900
cu. m and will be delivered in the 2Q 2009.
Excelerate Energy anticipates using the
ship to deliver regasified LNG to its Gulf
Gateway terminal offshore Louisiana as well
as support their application to construct
the Northeast Gateway terminal located offshore
in Massachusetts Bay, near Boston. The vessel
is owned by a 50/50 joint venture between
Exmar and Excelerate Energy, as is the revised
ownership structure for the vessel, Explorer,
announced in July.

Lessons
Learned from the Installation of the World's
First Regas Buoy Jens
Kaalstad, president, Advanced Production
and Loading (APL)
APL’s submerged turret
loading (STL™)
system, some 116 miles offshore Louisiana,
will have accumulated nearly one year of
operations since Excelerate Energy began
offloading LNG in March 2005. Similar STLs
have had decades of performance in the North
Sea. Kaalstad has been asked to describe
the lessons learned from the installation
of the first LNG STL and how new designs
will benefit from the experience.

Why
Conventional Terminal Developers Should
Respect Regas Ship Competition John
Wolff, director, LNG, Zeus Development Corporation
While LNG turret and buoy systems are commonly
more expensive per MMBtu than conventional
terminals, smaller investment is devoted
to fixed infrastructure, which makes the
turret and buoy systems highly flexible
and able to target profitable peak-demand
markets. What seasonal premium is enough
to warrant developers adding turret and
buoy systems on top of conventional shore-based
terminals, and what are the implications
for profitability to the owners of conventional
terminals? Wolff will address these questions.

The
Neptune Deepwater Project - Supplemental
Gas Supply to Everette Richard
M. Paglia, vice president, Market Development,
SUEZ LNG NA LLC
The Neptune Deepwater project is a prime
example of a regas-ship buoy in concert
with an existing terminal, the Distrigas
terminal in Everett, Massachusetts. Suez
is the owner of the Distrigas terminal and
in October 2005, it received a letter from
the U.S. Coast Guard deeming its application
for the Neptune Deepwater Port complete
and ready for review. Without the project,
Suez says, New England could face a supply
gap approaching 500 million cubic feet per
day by 2010. Paglia has been asked to describe
how the two terminals will work together
and the implications around the world for
other onshore baseload terminals with buoys.

Regasifying LNG in Cold Water Tony
LaValle, Chicago Power & Process
An advantage of Excelerate Energy's Gulf
Gateway deepwater terminal is the ability
to use seawater as the warmant to vaporize
LNG. In colder waters like those offshore
Massachusetts, ships will need to use other
sources of heat. This presentation will
discuss these issues.

Making
Every Ship a Potential Regas Ship: Latest
Advancements in the Remora HiLoad Technology Lars
Odeskaug, president, TORP Technology
Remora Technologies' HiLoad system would
allow any conventional LNG ship to serve
as regas ship. The technology is designed
to allow faster vaporization of the cargo
-- up to 1.0 Bcf/d, and thereby, improve
the economics of the terminal. Odeskaug
will describe the latest design elements
and the implications of seawater vaporization.

A
Non-Biocide Approach to Ship Regasification:
The Latest Advancements in the Bishop Regas
Process Bill
Bishop, Conversion Gas Imports
CGI has done further work on its vaporizer,
indicating the impact on seawater biota
should be low. The basis for this low kill
rate is that CGI injects no biocide into
the seawater, but rather uses a recyclable
flush system between deliveries. Moreover,
the fluid dynamics indicate that biota do
not come in contact with the cold wall of
the heat exchanger. CGI has applied to the
DOE for funding to demonstrate this.

2: U.S. Seawater Vaporization: Getting to
Resolution
Concerns for Seawater LNG Vaporization
and Steps Being Taken by NOAA to Investigate
Its Harmful Affects William
T. Hogarth, assistant administrator for
fisheries, NOAA
The unknown effect of LNG vaporization systems
on marine biota has been an issue for the
fishing industry and other groups concerned
for marine habitat. Consequently, regulators
have delayed applications for offshore LNG
terminals that rely on seawater vaporization
until further studies can be performed.
Yet, approximately 80% of the world's LNG
is vaporized with seawater, especially in
Japan -- a nation heavily reliant on its
fishing industry. Moreover, the replacement
technology for seawater vaporization is
most often gas-fired systems that consume
fuel and emit carbon pollution. What is
the current position of NOAA on seawater
vaporizers and when might a decision about
their use be issued? These are some of the
questions posed to Hogarth.

Potential
Effects on Marine Biota from Seawater Use
at LNG Terminals Dr.
Craig Swanson, principal, Applied Science
Associates
Applied Science Associates (ASA) is an international
leader in developing and using computer
modeling tools to address challenges regarding
water pollution, from permitting facilities
to accidental spills. ASA has extensive
experience in analyzing the biological effects
from the construction and operation of many
types of facilities, including offshore
LNG terminals. Dr. Swanson and Dr. Deborah
French McCay led the technical team at ASA
in studying the effects of seawater vaporization
on marine life for several proposed offshore
LNG facilities. Dr. Swanson's presentation
will describe the prime issues with this
technology and how industry might address
these issues.

Biocides: Fundamentals of
Ecological Risk Assessment; Applications for
Biocides in LNG Kent
B. Woodburn, ecotoxicologist, Dow Chemical
Company Biocides are commonly introduced
into the flow stream of seawater heat-exchange
systems to kill microorganisms that would
foul heat exchangers or other sensitive process
equipment. As such, discharge of such compounds
has the potential to adversely impact ecosystems.
The current risk-based tool for assessing
these types of impacts is the process of ecological
risk assessment (ERA), which is designed to
assess the likelihood of adverse ecological
effects associated with environmental contamination.
This presentation will provide an overview
of ERA and the new probabilistic methods used
to quantify the relationship between exposure
and effect.

Offshore
Alternatives to Open-Rack Vaporizers Joe
Nelson, manager, Mustang Engineering
Mustang Engineering has devised an alternative
solution to seawater vaporizer systems.
Are they large enough to do the job, without
causing excessive fog? What is their cost
and foot print relative to conventional
open-rack or shell-and-tube vaporizers?
These are some of the questions to be posed
to Souder.
