2000 Dispersal
of Produced Formation Water from an Oil Production Facility
The
environmental effects of Produced Formation Water (PFW) discharged from offshore
oil production platforms into the marine environment is of growing concern among
environmental regulators and industry. Analyses of PFW discharges have found various
concentrations of hydrocarbons, which are potentially toxic to marine organisms.
Environmental agencies require petroleum companies to carry out predictive dispersion
modelling to determine the likely distribution and concentration of PFW after
discharge from a platform and its toxicity to surrounding marine ecosystems.

Asia-Pacific
ASA (APASA) were commissioned by Apache Energy to forecast the dispersal of
PFW from the "Stag" oil production platform on the Northwest Shelf,
Australia. To simulate the PFW release under environmental conditions, APASA applied
numerical models to describe two important processes. Firstly, the hydrodynamics
of the receiving waters was simulated by Mr Scott Langtry of GEMS (WA) using the
three-dimensional circulation model, GCOM3D. Secondly, the mixing and dispersion
process was simulated using the subsurface plume model, MUDMAP. MUDMAP was used
to assist in understanding the dilution, mixing and ultimate fate of PFW
when discharged from "Stag". Included were estimates of the excursion
of the plume until concentrations weremixed to levels well below those of likely
environmental concern. The
information was used by John Nielsen and Shane Chaplin, scientists from International
Risk Consultants (IRC), to select appropriate sampling sites for testing seawater
concentrations of hydrocarbons arising from discharged PFW. The results provided
by APASA assisted the IRC scientists in locating and sampling within the plume
at different times during the day and during different stages of tidal water movement.
IRC's field observations confirmed the MUDMAP predictions of plume dynamics
under average prevailing conditions experienced in the region during autumn. Finally,
peak concentration levels attained from both the simulations and the laboratory
analysis from the field sampling, were used by the Apache Energy environmental
managers to demonstrate that the total oil concentrations are well below the Statutory
Release Concentration for platform PFW discharge in Western Australia. Back

Maritime and Port Authority of Singapore Takes Delivery of OILMAP ASA
recently secured a contract from the Maritime and Port Authority of Singapore
(MPA) to deliver the latest version of our oil spill trajectoryand fates model;
OILMAP. As well as regulating and managing the busiest port in the world in terms
of shipping tonnage, the MPA has responsibility for a wide range of marine environmental
programmes and maritime contingency plans in Singapore. Being at the cross-road
of international shipping routes and near one of the busiest waterway in the world,
MPA has an important national responsibility for responding to all spill incidents
in and around Singapore waters. In support of this requirement, MPA
has decided to upgrade their existing spill response software systems among other
plans to help meet both their future maritime technical and operational needs.
Eoin Howlett and Roddy Thomas recently visited Singapore to deliver OILMAP and
completed a comprehensive training programme for key model users in MPA's offices.
The contract includes the latest version of OILMAP's multiple spill prediction
trajectory and back tracking models, and the integration of a range of comprehensive
environmental databases.
MPA
developed high resolution current data for the region which was integrated into
OILMAP. Back

News Eoin
Howlett, Sasha Zigic and Brian King travelled to Perth, Western
Australia in early May for a SIMAP training session with environmental managers
Libby Howitt from Apache Energy and Scott Langtry from GEMS (WA). Shown (from

Eva Stejskal (environmental manager for Apache), Scott and Eoin.
Craig
Swanson participated in the North Kingstown High School Career Day 2000 on
12 April. Although he was not able to convince any students to take up hydrodynamic
modeling as a career during his presentations he did discuss the type of work
that computer modelers (of all kinds) do, what sorts of background education is
needed and examples of the jobs these student can expect.
Craig Swanson and Matthew Ward participated in Narragansett Bay
Summit 2000 held 24-25 April. They hosted the ASA display booth and participated
in various sessions on research, transportation, industrial development, tourism
and fisheries. The summit was designed to bring the diverse stakeholders together
to discuss the state of the bay, multiple uses and how competing interests can
come together to ensure that the bay remains a unique resource. Craig
Swanson presented a talk entitled Pollutant Fate and Transport Model of
Salem Sound at the State of the Sound: Current Knowledge and Future Directions
symposium held 25 May. The purpose of the symposium was to communicate to stakeholders
the present state of research about the sound and included discussions about future
issues to be addressed. Steve

Eoin Howlett
visited with Alan Hutchings, Emergency Planning Officer for Dorset County Council,
UK. Dorset County Council use OILMAPX, the Mapinfo version of OILMAP to integrate
pollution planning with ARCS charts, UK Ordinance Survey charts, Vertical Aerial
photographs and high resolution vector GIS information. Alan Hutchings (right)
and Steve Spring worked with Eoin to customize the system to meet Dorsets
specific needs. Eoin
Howlett travelled to the lovely Isle of Man in the Irish Sea in May to deliver
a SARMAP upgrade to the Isle of Man Coast Guard. Captain Colin Finney and Erica
Kermode were trained on allocating response resources for Search & Rescue
operations using SARMAP.
Eric
Anderson and Malcolm Spaulding attended the 2000 Arctic and Marine
Oilspill Program (AMOP) in Vancouver, British Columbia in June. They presented
a paper on deep water oil spill blowout modeling which demonstrated ASA's integration
of gas hydrate formation in several deep water blowout sensitivity studies. June
14-16 Deborah French presented her work on oil toxicity at the 23nd
annual Arctic and Marine Oilspill Program(AMOP) Technical Seminar in Vancouver,
BC. She has developed and validated an additive model for the toxicity of the
aromatic components of oil. She also enjoyed the scenery and social aspects
of the conference venue.
Eric
Anderson traveled to Buenos Aires in April to deliver OILMAP training to Total
Argentina personnel, together with Sergio Wojda of Morken, S.A. who distribute
ASA's software in Argentina and Luis Vila, who assists in the training and application
of these applications.
Dr. Deborah French was a co-presenter of a workshop in Kuwait April 28-May
3 on marine NRDA procedures and practices. She provided an overview of methods
for assessing damages to marine biota and habitats, including the use of modeling
to evaluate oil fates, impacts, and damages. The models included in NRDA regulations
in the United States were described. The workshop participants worked through
modeling of case examples, both historical and for an existing nearby site in
Kuwait. In
the light of the recent ERIKA spill incident offshore France, IFREMER recently
invited Dr. Deborah French to their Brest office and present ASA's spill
impact analysis model system, SIMAP. IFREMER is a public company under the administrative
supervision of various French Ministries including Education, Research and Technology,
which particularly focuses on agriculture and fisheries. Debbie French and Roddy
Thomas conducted a one day SIMAP workshop with IFREMER and other agencies, and
included a detailed overview of the system's science, its validation, capabilities
and range ofpotential applications, including to the ERIKA spill.
Roddy Thomas recently attended Environment and Water Quality India 2000,
in Delhi, a conference specialising in a wide range of marine and fresh water
quality problems presently be addressed by both industry and government in India.
A number of ASA's model systems were demonstrated at ASA's stand including a number
of WQMAP applications covering industry and domestic effluent discharge dispersion,
dredging and thermal discharge dispersion studies. Back

warm congratulations to Roddy Thomas, ASA's UK director with responsibility
for our international sales and marketing, and his wife Victoria, who recently
celebrated their wedding in Chelsea, London on 27 May. After a short honeymoon
on the Mediterranean island of Corsica (see picture), they are setting up home
in St Andrews, Scotland.

There must have
been something in the air, another big ASA wedding occurred on April 22 when our
accounting manager, Linda Nolan married Gary Gagne. Despite stormy winds
and torrential rain, they happily tied the knot at 6am on Narragansett Beach. Back
