As more natural gas reserves are found in increasingly remote areas, a problem facing the gas industry is how to transport the gas to its end users. Historically, the most common mode of transportation has been through pipelines. However, with large transit distances involved, transport by ship to LNG terminals is the only cost effective alternative. In order to assess the potential consequences of LNG operations on the environment and human safety, ASA has focused on several LNG-related modeling efforts. These include the determination of spread and thermal radiation zones in the event of an LNG spill on water, and the potential effects on marine biota from both the construction and operation of offshore LNG facilities.

Consequence Analysis of LNG Spills
ASA is now completing the alpha phase of LNGMAP, an LNG model to determine fate and transport of LNG on the water surface and in the atmosphere, as well as the extent of thermal radiation in the event of a fire. This tool can be used to perform consequence analysis of LNG spills from offshore LNG facilities, LNG tankers and pipelines.

Entrainment and Impingement of Marine Biota
A major operational issue for offshore LNG terminals is the technology used for regasification. Open Rack Vaporization (ORV), the preferred method to heat the LNG, uses the heat from seawater. When the cooled seawater is discharged, it can sink to the bottom, potentially affecting benthic species. Of more concern, however, is the entrainment and impingement of marine biota in the seawater moving through the heating system. Since large volumes of water are used, the loss of fish, as well as eggs and larvae, can have an impact on population levels. ASA has been working with the developers of proposed offshore LNG facilities to determine the potential entrainment and impingement effects for specific species.

Construction Effects
The construction of both LNG terminals and their connecting pipelines will impact the benthic communities in their vicinity. Benthos will be directly affected in the footprints of these facilities and indirectly in adjacent areas, particularly in the short term. ASA's analyses of both sediment concentrations in the water column and the deposition patterns generated by jet plows used to bury pipelines are providing quantitative estimates of these impacts.





ASA has been working with WeatherFlow (www.weatherflow.com) to link to WeatherFlow's network of real-time weather stations and mesoscale wind models. These weather stations are installed at meteorologically strategic locations that fill gaps in the public data network throughout coastal locations of the United States, Canada, and most recently Mexico. The operational regional meteorological wind models use advanced data assimilation to provide high resolution forecasts for coastal regions. WeatherFlow observational and model data provide a unique source of wind and weather information for a variety of clients including the military, commercial maritime industry, recreational boating community and the National Weather Service. ASA's COASTMAP extension for ArcGIS 9.0 allows the WeatherFlow observation and model data to be integrated in its native formats (GRIB, NetCDF), for ArcGIS display, animation, analysis and linkage to other data products and forecast models.

ICS_Tampa
The map shows GIS information for the Tampa Bay area necessary to assist planners and responders for emergency incidents. The form shows the ICS organizational structure used in CMS.

The concept of the Incident Command System (ICS) was developed more than thirty years ago after wildfires burned over one-half million acres of Southern California, killing 16 people and destroying 700 buildings. Criticism of the response to the 1970 fires focused on the failure to provide leadership in solving cooperation, command and control, communications and training issues for responders. An interagency group was formed to address the problems and ICS was born. Now when a natural event or terrorist attack occurs in the U.S., the response and recovery are most often managed using the Incident Command System because it provides the command structure necessary to quickly assemble an effective response organization in a potentially chaotic emergency situation. The ICS organizes personnel into a hierarchical structure so that everyone knows his or her responsibilities as well as their place in the organization. The ICS also facilitates the deployment and tracking of response resources such as vessels, aircraft and rescue vehicles to multiple locations in the response, and provides mechanisms for the management of these resources through a cycle of work periods lasting days and sometimes weeks. ICS contains the organizing principles, organizational structure, operating and communications protocols and common terminology around which emergency preparedness planning, response and recovery operations are based.

In February 2003, the U.S. Homeland Security Presidential Directive 5 directed the Secretary of the Department of Homeland Security to develop and administer a nationwide system, called the National Incident Management System (NIMS), which provides a consistent approach for Federal, State and local governments to prepare for, respond to and recover from all domestic incidents. ICS forms the backbone of the NIMS, providing standards for management, terminology, span of control and communications during all phases of incident management. HSPD-5 also requires all Federal departments and agencies to adopt and use the NIMS in their incident management and emergency preparedness, response and recovery activities.

Government agencies at all levels use the ICS for a range of applications. The Federal Emergency Management Agency (FEMA) uses ICS for managing the response and recovery from naturally occurring events such as hurricanes, tornadoes and floods. The Forest Service and the National Park Service have built their wildfire response and recovery operations around ICS. The US Coast Guard has been a leader in the adoption and use of ICS, applying it to hazardous materials spill response and recovery, and to search and rescue operations. ASA has implemented the Incident Command System in software systems used for crisis management by the US Coast Guard and international government agencies. Currently ASA is under contract to supply an ICS-based software system to the Transportation Security Administration (TSA) for use in an ongoing port security exercise program at major port areas around the U.S. As emergency preparedness, response and recovery become more important to organizations in the US, ICS will become more widely used and accepted for incident management practices.

 

 


SARMAP & the Western Australian Police Service

The Western Australian Police Service have committed to adoption of the SARMAP system covering waters off the coast of Western Australia, which stretches for over 18,000 km. Asia Pacific ASA is customizing the system to include tidal and geostrophic current inputs as well as GIS data covering the state.

Antigua Barbuda Search and Rescue Utilize SARMAP in Rescue
Antigua Barbuda Search & Rescue (ABSAR) uses SARMAP to assist in logistical support for missing vessels in the waters surrounding Antigua and Barbuda. On 14 May, ABSAR assisted in retrieving a Trans-Atlantic rower, James "Tiny" Little, using SARMAP. The rower was caught in a current about 50 miles NE of Antigua and running out of food. Although ABSAR had good communications with Tiny, they used SARMAP to predict his drift so that the retrieval vessel could plot an accurate course for intercept. The search team found him within 1.5 miles of the predicted location.

 

 


During the first week of April, Kelly Knee delivered and conducted training for the OILMAP, CHEMMAP, and SARMAP ESRI ArcGIS extensions to the Rijkswaterstaat North Sea Directorate (RNSD) in Rijswijk, The Hague.
