1. INTRODUCTION
Oil spill hazard is an event that
occurs suddenly and has complex impli-
cations. It leads to the loss of animal life,
property damage, environmental degra-
dation, and signicant disruptions to lo-
cal activities. Addressing such incidents
requires extensive resources, equipment,
skills, and coordinated efforts from multi-
ple agencies. The vulnerability to oil spills
varies across regions, but a substantial
part of the country is exposed to these
hazards, which can have far-reaching
socio-economic consequences and ad-
versely impact coastal communities.
While many contingency plans
and procedures for oil spill management
and relief are not standardized, some
emergency response agencies have ad-
opted systematic and computer-based
approaches for oil spill monitoring and
detection. Various computer-based emer-
gency response procedures are available
in the market, each offering different func-
tionalities for oil spill emergency response.
However, the diversity of databases with
different formats poses challenges in in-
tegrating these systems into a unied
framework for oil spill contingency. Conse-
quently, the lack of compatibility between
platforms, database formats, and system
congurations hampers effective oil spill
contingency efforts. Furthermore, most of
these systems operate ofine, providing
results that are not in real-time. Conse-
quently, utilizing these systems for oil spill
emergency response can be complicated,
costly, inefcient, and time-consuming.
Note that while these systems have
their limitations, they still play a crucial role
in mitigating the impact of oil spills and fa-
cilitating emergency response efforts.
NOAA Emergency Response Di-
vision (ERD) has recently adopted a suite
of modules tailored to oil spill trajectory
modeling and emergency response [1].
These modules, namely Computer-Aided
Management of Emergency Operations
(CAMEO) and General NOAA Operational
Modeling Environment (GNOME), are spe-
cically designed to support rst respond-
ers and emergency planners [2]. The in-
tegration of these modules is a signicant
milestone in the advancement of oil spill
emergency response technology in Can-
ada. However, there is still more work to
be done.
The GNOME trajectory model is
renowned for its impeccable algorithmic
performance. However, the user’s exper-
tise is crucial in conguring the model to
operate in diagnostic mode for spill re-
sponse. Despite the integration of these
two systems into a unied platform, they
do not encompass all the prerequisites for
oil spill management and emergency re-
sponse. A comprehensive system for oil
spill management should encompass all
the necessary procedures and information
required before, during, and after disas-
ters occur.
Oil Spill Information System (OSIS)
and Shoreline Oil Cleanup Recovery and
Treatment Evaluation System (SOCRA-
TES) are two systems developed by BMT
Marine Information Systems Limited and
AEA Technology PLC to facilitate oil spill
contingency planning [3]. While OSIS is
employed for oil spill trajectory simulation,
SOCRATES serves as a tool for contingen-
cy planning, providing detailed insights
into coastal characteristics, sensitive sites,
access points, and equipment bases. The
system boasts a robust database encom-
passing oil types and weather information,
along with commendable functionalities
for oil spill contingency. However, it still
lacks certain essential requirements nec-
essary to coordinate disaster mitigation
and relief operations. Authorities require
more comprehensive information pertain-
ing to disasters to enhance preparedness
levels concerning disaster planning and
execution of mitigation measures.
To improve readiness for handling
oil spill disaster events, disaster teams
require a real-time data transaction infra-
structure. An operational oil spill disaster
data processing and dissemination system
is needed to support all operational mitiga-
tion and relief procedures during oil spill di-
saster contingency [4]. The system should
be based on proven disaster models and
methodologies such as GNOME & CAM-
EO. It should also include an interactive
system that covers real-time disaster man-
agement, operation, and administration.

The alert system is a crucial compo-
nent of the system that provides real-time,
medium-term, and long-term early warning
information to enable rapid response to oil
spill events. The system aims to provide
timely alerts for oil spill incidents, catering
to real-time, medium-term, and long-term
requirements The system receives infor-
mation about oil spill location through its
communication infrastructure and lever-
ages various data sources such as GIS
data, remotely sensed data, and monitor-
ing technologies like deployed sensors
and observant systems. The Environmen-
tal Sensitivity Index (ESI) map serves as a
long-term early warning system for oil spill
risk, while trajectory simulation results over
this map offer medium-term risk early warn-
ing. Disaster models play a crucial role in
providing essential disaster products and
information. The Command & Control Sys-
tem facilitates disaster management and
administration. The Communication Sys-
tem enables authorized personnel and
disaster players to exchange data effec-
tively. In summary, the alert system is an
essential tool that provides timely alerts for
oil spill incidents, catering to real-time, me-
dium-term, and long-term requirements. It
leverages various data sources such as
GIS data, remotely sensed data, and mon-
itoring technologies like deployed sensors
and observant systems. The Environmen-
tal Sensitivity Index (ESI) map serves as
a long-term early warning system for oil
spill risk, while trajectory simulation re-
sults over this map offer medium-term
risk early warning. Disaster models play a
crucial role in providing essential disaster
products and information. The Command
& Control System facilitates disaster man-
agement and administration. The Commu-
nication System enables authorized per-
sonnel and disaster players to exchange
data effectively.
Database
To ensure effective situational anal-
ysis and disaster modeling, an integrated
database plays a pivotal role in consolidat-
ing input data from various agencies and
departments. These entities act as custo-
dians for essential information required for
oil spill modeling, assessment, and emer-
gency response. The integrated database
serves as a centralized repository, facili-
tating seamless access to crucial data. It
encompasses a wide range of information,
including weather data, sea states, and
other relevant parameters. While some of
this information is linked to the database
online and in real-time, other pre-existing
data is readily available for analysis. The
database structure includes spatial and
tabular information, which are indispens-
able for the oil spill disaster management
process. All processed data resulting from
disaster modeling and analysis is meticu-
lously stored within the database, ensuring
its availability for retrieval by authorized di-
saster players.
Disaster Models
Disaster models play a pivotal role
in oil spill disaster management by pro-
viding essential information about oil spill
locations, trajectory, risk areas, damaged
areas, and emergency response. These
models are primarily developed within
the Geographic Information System (GIS)
framework to generate accurate informa-
tion and products for oil spill disaster sce-
narios [5]. Additionally, there are models
that operate outside the GIS environment
but are compatible with various GIS en-
gines, such as OSIS, Oil Spill Risk Analysis
(OSRA) model, and GNOME [6], [7]. Re-
gardless of the specic application mod-
ules employed for oil spill modeling and
analysis, the resulting products can be
seamlessly integrated into an integrated
oil spill disaster management, operation,
and administration system database (Or-
acle 10g). This integration is facilitated by
ESRI’s ArcSDE and Feature Manipulation
Engine (FME) software. ArcSDE serves
as an advanced geographic application
server for relational databases, enabling
efcient management of geographic in-
formation within a database server and
seamless data sharing across all ArcGIS
applications. On the other hand, FME pos-
sesses the capability to integrate diverse
geographic features with geographic in-
formation analysis software.
The integrated database is a crit-
ical component of the system that plays
a pivotal role in situational analysis and
disaster modeling. It serves as a central-

ized repository for input data from various
agencies and departments that act as
custodians for essential information re-
quired for oil spill modeling, assessment,
and emergency response. The database
encompasses a wide range of information,
including weather data, sea states, and
other relevant parameters. While some of
this information is linked to the database
online and in real-time, other pre-existing
data is readily available for analysis. The
spatial and tabular information required
for the oil spill disaster database is listed
in Table 1 [8]. All processed data result-
ing from disaster modeling and analysis is
meticulously stored within the database,
ensuring its availability for retrieval by au-
thorized disaster players.

(Table 2).
To ensure effective disaster re-
sponse, relevant disaster products can be
conveniently loaded through the internet
portal. These products serve as valuable
references for disaster responders, en-
abling them to make informed decisions
and take appropriate actions. The system
further streamlines the process by provid-
ing relevant commands and tasks through
forms, emails, or messages. Pre-designed
forms are an integral part of the command
and control system, ensuring that each
authorized person receives customized
forms tailored to their specic responsibil-
ities and tasks.

Communication System
The communication system’s core
infrastructure is an internet portal that ef-
fectively manages all incoming and outgo-
ing transactions while enabling real-time
communication among various disaster
players. This portal also serves as a robust
platform for distributing data to individuals
such as shermen and other stakeholders
involved in coastal areas, including hotels,
resorts, tourism areas, and villagers. These
diverse groups have distinct requirements
concerning details and response times re-
lated to oil spills.
To cater to emergency needs, a
dedicated portal manager oversees the
on-scene commander and personnel man-
agement in the eld. Their primary respon-
sibility revolves around organizing all eld
activities and providing comprehensive
support for activity planning, logistics, and
resource allocation. Portal managers can
hail from different organizations, including
control centers, civil protection agencies,
local administrators, technical or scientic
personnel, or operators in a call center.
The internet portal is designed to
be highly intuitive and user-friendly, ensur-
ing seamless navigation for all authorized
users. It offers a wide array of features and
functionalities that empower disaster play-
ers to effectively communicate and col-
laborate in real-time. The portal’s robust
architecture enables it to handle large vol-
umes of data while ensuring optimal per-
formance and reliability.
In addition to facilitating real-time
communication, the internet portal also
serves as a centralized repository for criti-
cal information related to oil spills. It lever-
ages advanced data management tech-
niques to store and organize vast amounts
of data from various sources. This com-
prehensive database enables authorized
users to access up-to-date information re-
garding oil spill locations, trajectory analy-
sis, risk areas, damaged areas, and emer-
gency response protocols.
Furthermore, the internet portal
plays a crucial role in disseminating vi-
tal information to stakeholders involved
in coastal areas. By leveraging its exten-
sive network connectivity, the portal en-
sures that relevant data reaches individ-
uals such as shermen, hoteliers, resort
owners, tourism operators, and villagers
promptly. This timely information empow-
ers these stakeholders to make informed
decisions and take appropriate actions
based on the specic requirements of
their respective roles.
Overall, the internet portal rep-
resents a cornerstone of the communica-
tion system deployed for oil spill disaster
management. Its robust infrastructure and
comprehensive feature set enable seam-
less collaboration among disaster players
while ensuring efcient data distribution
across various stakeholders. By leverag-
ing cutting-edge technologies and best
practices in data management, the portal
serves as a reliable platform for real-time

4. SYSTEM ANALYSIS
The system is designed to evaluate
the capability of oil spill disaster players
through a core operation and administra-
tion system at the disaster management
center. It provides early warning, detection,
monitoring, and mitigation functionalities in
the event of an oil spill disaster. The system
includes oil spill disaster models designed
to produce situational information through
thematic products required in oil spill man-
agement and emergency response. Figure
4 shows the data ow diagram through dif-
ferent system components.
In the Central Repository System,
data collections have to be carried out
based on the specication of thematic lay-
ers required for oil spill disaster through
relevant agencies before a disaster hap-
pens. This will be prepared through down-
loading and uploading utilities. All of the
gathered data requires pre-processing,
which includes image pre-processing and
enhancement, vectorization, interpreta-
tion, and extracting related features and
converting them to an appropriate data
format for modeling. Finally, all pre-pro-

cessed data will be stored into a database
and will be ready to get utilized by specic
disaster models.
Oil spill disaster modeling and
analysis will proceed by using available
models to achieve disaster products im-
mediately after an oil spill disaster hap-
pens. All the data stated will be modeled
based on their particular models to gen-
erate various types of thematic products.
The major models/systems for oil spill di-
saster are shown in Figures 2 and 4.
One of the major advantages of
this system in comparison with other ex-
isting oil spill management systems is its
command and control module for oil spill
emergency response. The Command and
Control System is like an oil spill opera-
tion and administration ofce that enables
the disaster responders to have thematic
products and information on the current
oil spill event integrated with decision sup-
port. The system includes but is not limited
to the following sub-components.
a) Alert System: The Alert System uses
Email and SMS through Portal.
b) Disaster Operation: Disaster Operation
includes Situational Reporting, Request for
Resources, and Fill in Command Forms.
c) Disaster Declaration: Disaster Decla-
ration includes Incident Report, Red Alert,
and Thematic Products.
d) Correspondence: Correspondence in-
cludes Notication, SMS, Email, Contract
Directory, and Discussion Board.
e) Database Administration: Database
Administration includes Inventory Man-
agement, Organization Management, Fa-
cility Management, Human Resource Man-
agement, and Document Management.
f) Disaster Administration: Disaster Ad-
ministration includes Assign Privileges,
Resource Management, Task Manage-
ment, and Activate Operation Centers.
One of the advantages of this sys-
tem design is having a mutual commu-
nication through the internet portal. The
system can also implement other commu-
nication infrastructures. Situational data
from elds or disaster players can be sent
to the disaster operation and administra-
tion ofce for evaluation, updating the-
matic products, and decision making. The
portal system facilitates all functionalities
described for the command and control
system through forms, reports, emails,
messages, and other utilities. It is simply a
web page with several security levels that
allows accessibility to different people on
the ground like public, players, managers,
and VIPs to different data related to the oil
spill. The portal system is the core com-
munication system between all mentioned
parties involved with the disaster.
5. CONCLUSION
The system designed in this pa-
per is a solution to incorporate the dis-
tinct systems currently used for oil spill
management and make them a unique
multi-functional oil spill management sys-
tem. This makes the operational oil spill
management real-time, more efcient,
and systematic. It covers all aspects of
oil spill management before, during, and
after oil spill events, including disaster
warning, mitigation, communication, as-
sessments, documentation, and data re-
pository. The system can reduce warn-
ing alert and emergency response time.
The system can be easily integrated into
all available systems currently used for
oil spill monitoring and management like
GNOME & CAMEO or other new technol-
ogies to facilitate robust real-time and in-
teractive emergency response for oil spill
accidents. Oil spill response agencies
such as Canada-US Joint Marine Pollu-
tion Contingency Plan (CCG & USCG),
Environment Canada (EC), and other or-
ganizations can easily join their system
to this new web-based technology for
better and efcient oil spill management
and response. Finally, this architect de-
sign for oil spills can be used to develop
other disaster applications. By linking all
disaster applications like ood, landslide
forest re, and tsunami, the system can
be converted into a centralized multi-di-
saster support system [9], [10]. The sys-
