NEWS FROM AUSTRALIA:
SIMAP
Makes a Mark
Recent
discoveries of oil reservoirs off the northwest corner of Australia have prompted
a flurry of oil and gas exploration activity. But the area is also environmentally
sensitive. Large tracts of the North West Shelf and Timor Sea regions are made
up of shoal areas and island chains with wide fringing reefs, and the area also
supports rich benthic and demersal fisheries. 
Because
oil spills and leaks from drilling and production pose a potential risk to local
biology and habitats, Australian regulations require oil and gas companies to
perform quantitative risk-assessment studies prior to drilling, or in planning
new facilities. In the past, studies have focused on risks to shorelines from
surface slicks. However, oil companies and their government regulators are now
increasingly focusing on the risks presented to the subsurface environment by
dissolved and entrained components of oil slicks.
Recently, Asia-Pacific ASA have been commissioned by a number of clients, including BHPP, Chevron, Apache Energy and Woodside Energy, to quantify potential risks to sub-tidal habitats using ASA's three-dimensional oil spill fates and biological effects model, SIMAP. SIMAP's physical fate model is being applied to estimate potential concentrations of dissolved and entrained components of spills within the water column and to estimate rates of sedimentation to the seabed. SIMAP's sub-surface release capabilities have also been used to quantify risks to submerged habitats generated by blowouts at the seabed and corrosion leaks from submerged pipelines. The example figure shows a detail of a SIMAP application to a blowout study in the Timor Sea.
SIMAP's ability to separately predict the path of submerged and surface-bound spill components and to estimate hydrocarbon dosage rates as a product of concentration and duration of exposure have proven to be particularly helpful to resource companies aiming to better understand and describe environmental risks associated with their activities.

Crisis
Management Simulator
ASA's Crisis Management Simulator (CMS) is an integrated client-server software application for handling a variety of emergencies including:
- Chemical
atmospheric releases
- Nuclear releases
- Marine Search & Rescue
- Oil and chemical response
- Ship stability and general marine emergency response
The system also incorporates a comprehensive resource management system based on the ICS system that ASA originally developed for the U.S. Coast Guard. The system manages deployment and cleanup costs, provides estimates on damages to the environment, and simulates evacuation for minimizing the impacts on the population from toxic releases.ASA's project manager for the CMS, Eoin Howlett, is very pleased with the progress, "The development schedule has been on a fast track, and the integration of these components with the resource deployment and management system represents the first application of this type in the world."
The Crisis Management Stimulator is being delivered in December to MPA's new integrated Simulated Centre (ISC) building in Singapore. The ISC also contains a full mission bridge simulator from Kongsberg Norcontrol. This simulator is fully integrated with the CMS so that students in the bridge simulator will see data such as oil slicks and booms.

ICOPCE
Roddy
Thomas from ASA's UK office and Sasha Zigic from Asia-Pacific ASA attended
the International Chemical and Oil Pollution Conference & Exhibition
(ICOPCE) in Singapore on 3 – 4 September. In addition to exhibiting CHEMMAP, ASA's
updated chemical dispersion model, and other model systems, Sasha presented a
paper entitled "Crisis Management Simulator - An Effective Tool to Preparing
for Emergency Response'', at this increasingly popular and important regional
conference and exhibition.

News from Brazil
Eduardo
Yassuda delivered SIMAP to PETROBRAS (Petróleo Brasileiro S.A.) as part of the
research and training project to provide the Brazilian oil company with the modeling
capabilities and computational tools to determine ecological risk and damage assessment.
This first presentation focused on the use of the SIMAP interface and the use
of GIS for managing the natural resources database. During this 18-month project,
ASA will provide technical support and training for a group of 10 professionals
from CENPES (Petrobras Research Center), including biologists, chemists, toxicologists,
physical oceanographers, and GIS experts. The initial training will be completed
in November (6-8) when Deborah French McCay introduces the technical features
of SIMAP.
ChemWatch Joins Forces with CHEMMAP
Applied
Science Associates recently concluded an agreement with The ChemWatch Chemical
Management System. As a result, a software link is available between ASA's chemical
spill modeling system, CHEMMAP, and ChemWatch's large database of Material Safety
Data Sheets (MSDS) for more than 40,000 pure substances and 75,000 common mixtures.
CHEMMAP, which predicts the trajectory and fate of spilled chemical products,
currently has its own database of 900 chemicals with physical and chemical data
properties. The extensive suite of Health and Safety information contained within
the ChemWatch MSDS's complement and expand upon the data in the CHEMMAP database.
A sampling of the information available through the ChemWatch MSDS's includes
descriptions of essential personal protective equipment, exposure standards, health
hazards, biological exposure indices and possible First Aid requirements. The
ChemWatch MSDS's also provide guidelines for how to determine the severity of
the risk to health, how to handle a spill, how to store and transport chemicals,
how to dispose of chemicals, what to do if a chemical catches fire and how to
plan for an emergency response. The wide variety of information in ChemWatch's
MSDS's will enhance CHEMMAP's role as both a contingency planning and real-time
response tool.

On 14-17 August, Deborah French McCay attended and presented at the First International Congress on Petroleum Contaminated Soils, Sediments & Water in London, UK. She presented a half-day workshop titled: "The Role of Modeling in Natural Resource Damage Assessment for Oil Spills". This workshop focused on the usefulness of computer modeling, in conjunction with field data, in assessing impacts. The North Cape oil spill provided a good example case study. The workshop was well attended and there was a lively and interesting discussion on the topic.
Matthew Ward, Craig Swanson and Malcolm Spaulding traveled to Philadelphia for the semi-annual meeting of the Drexel University/ University of Rhode Island/ ASA/ NOAA/ Brown University National Ocean Partnership Program project held on 10 September 2001. The project is focused on the development and application of an Internet-based monitoring and forecasting system for Narragansett Bay.
Eric Anderson and Eoin Howlett have been traveling to Singapore monthly as part of ASA's Crisis Management Simulator (CMS) Project for the Maritime Port Authority of Singapore. The CMS will be delivered in December of this year and will be linked directly with a ship simulator system from Kongsberg Norcontol.
ASA Software Being Used in WTC Response
The US Coast Guard is using software developed by ASA to help coordinate its response to the World Trade Center disaster in New York City. Members of the Coast Guard National Strike Force responded to the scene to apply their expertise in emergency response and deal with the dangerous conditions at the site of the recent terrorist attack. USCG personnel working around-the-clock use the prototype of the On-Scene Command and Control (OSC2) application to help manage people deployed to contain hazardous materials, including phosgene, methane, PCB's and asbestos, from the massive debris pile created by the collapse of the Trade Center towers. Chris Galagan traveled to US EPA district offices in Edison, New Jersey in September to support the Coast Guard's use of OSC
