On 26 May, Sasha
Zigic traveled to Melbourne to present the findings of a novel
pilot dispersant modelling study to the stakeholders for Western Port
Victoria. At the forum a number of agencies were represented along with
ESSO Australia and community group leaders. The pilot study is to assist
in decision making concerning the use of dispersant in the event of
a spill.
Sasha Zigic was a participant at
the annual ConocoPhillips Indonesia Incident Management Team training
held in Jakarta. Sasha presented "Fate and Effects of an Oil Spill
on Water" and "Trajectory Modelling (OILMAP)". Sasha
also presented "Response Trajectory Modelling" to the Incident
Management Assist Team from the ConocoPhillips Asia-Pacific region.
The presentations covered data requirements and various software tools
that can be used for a range of marine emergencies including oil spills
(surface and sub-surface), chemical spills and search and rescue.
Marc Zapata from Asia Pacific ASA's
Queensland office is spending the next three months supporting the Perth
office of Asia Pacific ASA.
In March, Scott Langtry delivered
an OILMAP update and provided training to Woodside Energy Ltd operating
within the Australian Bureau of Meterology. This system has now been
in place for 4 years. As part of this update, Scott installed tidal
data files to support OILMAP operations in Bass Strait, Australia.
Sasha Zigic was invited to present
at the National Plan Marine Chemical Spill Response Course held in Glenelg,
South Australia, 2 March. The presentation titled "Decision Support
Tools for Chemical Spills - Chemical Plume and Spill Modelling"
covered ASA's hydrodynamic (HYDROMAP) and chemical (CHEMMAP) models
and their use for planning and response. Following the presentation,
CHEMMAP was used as part of desktop exercise to examine the potential
impacts from a hypothetical styrene spill at the mouth of Bass Strait.
In February, Scott Langtry gave
a briefing on the SARMAP model to the Western Australian Water Police,
as a follow-up to assistance provided with that model by Asia Pacific
ASA to locate an elderly couple lost at sea off metropolitan Perth.
Sasha Zigic, Scott Langtry
and Nathan Benfer assisted Western Australian Water
Police with their search and rescue efforts, 5-7 January 2005. Numerical
modelling was undertaken to locate an elderly couple that went missing
after they set off in their small inflatable raft from Rottnest Island,
Western Australia, to paddle out to their yacht moored only 60 meters
offshore. At 17:30 on the 4th of January a crayfisherman discovered
the raft floating empty. The location of the raft was then compared
with the model predicted search area and it was found to be contained
within its limits. Since the persons were still lost at sea, a number
of release sites were added along th dingy track line from the previous
simulation. The release sites were run simultaneously and a search area
was created to encompass all possible locations of the missing persons.
This predicted search area was then used by the Western Australian Water
Police as part of their search.
Eoin Howlett visited ASA's office
in the Gold Coast, Australia, 4-7 December. Eoin spent a few days working
on soem joint projects with Brian King, Sasha Zigic and Marc Zapata,
including design of an ArcGIS extension for the Australian Navy.
Scott Langtry traveled through
Papua, New Guinea, 15-22 Nov. to review fuel, oil and chemical handling
procedures followed by Ok Tedi Mining Limited, who operate the Ok Tedi
gold and copper mine in the Western Province of Papua, New Guinea. APASA
is applying BF-HYDRO and HYDROMAP to model water circulation along the
Fly River and in the Gulf of Papua, respectively. OILMAP, SIMAP and
CHEMMAP are being applied in stochastic mode to quantify social and
environment risks from defined spill scenarios.
Asia Pacific's premier marine environmental pollution
prevention and response conference, Spillcon, was held in Brisbane,
Australia, 23 - 27 August. Brian King, Marc
Zapata and Sasha Zigic shared a booth with
John Leeder, Bill Stavropoulos and Rean Monfils from Leeder Consulting,
and provided information about our various services. The conference
was considered a great success with approximately 250 delegates from

Sasha Zigic presented a paper "Modelling
the 3-dimensional flow between the Nerang River Estuary and Burleigh
Lakes system, Gold Coast" at the 8th National Conference on Hydraulics
in Water Engineering, Gold Coast on the 16th July 2004.
In the first week of July Sasha Zigic
provided Greg Terrens, Sarah Sheales and Katrina Kaufman from ESSO Australia
with an intensive 1-day OILMAP training course. The training course
exercises provided hands on experience for emergency response and contingency
planning for their various operations around Victoria.
Kathy Sheridan presented the results
of the Port Walcott Oil Spill Risk Assessment study to the Western Australian
Department for Planning and Infrastructure (DPI). HYDROMAP and SIMAP
were used to estimate the rate of spread of a possible oil spill, and
results were added to the WA Oil Spill Response Atlas to help guide
spill response.
As part of the technology transfer, 8 senior The
Australian Maritime Safety Authority (AMSA) staff (Trevor Gilbert, Peter
Hadrill, Tracey Baxter, Karen Shaw, Shane Wilde, Paul Nelson, Keith
Brown & Lisa Holman), underwent a three day intensive HYDROMAP and
OILMAP training course from the 28-30 June, carried out by Sasha
Zigic and Marc Zapata. See story in Articles
for more details on the technology transfer.
Results of modeling for a proposed major port facility
in Cockburn Sound, Western Australia, were presented to the Fremantle
Port Authority by Scott Langtry on 10th June. The modeling, which was
carried out by Scott Langtry, Sasha Zigic
and Kathy Sheridan of Asia Pacific ASA using WQMAP,
compared local and regional-scale impacts of 5 conceptual designs for
an artificial island in terms of circulation and flushing.
At the invitation of ConocoPhillips Indonesia, Scott
Langtry of Asia Pacific ASA gave a presentation on 5 May, in
Jakarta, to the company's Crisis Management team on the behaviour of
oil on the sea, which was followed by a demonstration of how the OILMAP
and SARMAP software can greatly assist with forecasting this behavior
for effective emergency response. The presentation formed part of a
three-day training program that involved response exercises to a range
of marine emergencies, which made use of the HYDROMAP, OILMAP and SARMAP
models as well as automatic data links to weather forecasts through
COASTMAP.
Sasha Zigic participated in the
National Environmental and Scientific Coordinators (ESC) workshop in
Tasmania, Australia, 10 & 11th March, 2004. ESC's from around Australia
attended the workshop along with other environmental personnel from
Defense, the oil industry and other government agencies, to address
various issues relating to marine incident response, including advances
in modelling tools. As part of the workshop Sasha also presented a paper
on the various ASA commercial hydrodynamic (HYDROMAP & BFHYDRO)
and spill (OILMAP, SIMAP & CHEMMAP) management tools available to
an ESC, to address issues relating to marine incident response with
a view to minimizing damage to the coastal and marine environments.
Sasha Zigic and Brian King
were the keynote speakers at an "Offshore Drilling Workshop"
organized by International Environmental Management Co. Ltd in Bangkok,
Thailand. The purpose of the workshop was to provide a forum in which
personnel from government agencies and the oil industry could raise
and address questions about ASA's sediment and solute model, MUDMAP,
which has/is used extensively to simulate mud and cuttings discharges
into the Gulf of Thailand.
Thailand's Pollution Control Department (PCD) and
Chulalongkorn University recently purchased ASA's oil spill model, OILMAP
for Arcview, to assist in planning and emergency decision making for
the Gulf of Thailand. Ten of the PCD staff underwent an intensive three-day
training course carried out by members of the Asia-Pacific office, Sasha
Zigic and Brian King. The training course
provided a thorough understanding of how the OILMAP for Arcview system
in conjunction with PCD's extensive Arcview GIS database can be used
for spill exercises, response and as a prosecution tool in the event
of a spill. The Gulf of Thailand is a semi-enclosed sea, measuring approximately
400km by 800km, covering an area of about 320,000 square kilometers.
Millions of people derive their livelihood from fish and mineral resources
produced from the Gulf, and millions more can/are affected by changes
in the environment of the Gulf.
East Asia Response Private Limited (EARL) is an
international Tier Three Oil Spill Response Centre established in 1993
to provide rapid and efficient response to oil spill incidents in the
Asia-Pacific region. EARL responds to oil spills with equipment and
specialist staff to combat spills and provide technical support. EARL
recently purchased ASA's oil spill model (OILMAP) to assist with tracking
the weathering and movement of the spilled oil to assist the on-scene
responders. Mr. Sasha Zigic from our Australian office,
