AIS Collection
• Limitation of AIS coverage (meteorological conditions, height of
AIS base antenna)
• AIS base stations available?
• No data on oil transport
• The transponder is not operational or the transponder is not
properly working
• Vessels equipped with a Class-B AIS transponder
AIS Analysis
• AIS data sorting and cleaning
• Traffic density
• Traffic sorting by ship size, ship type
Oil Transport Data
•
•
•
•
Collection of oil transport data
Analysis of oil flow data
Compliance with AIS data regarding time and area
Inclusion of transit
Parameter Identification
Sensitivity - Vulnerability
SOS
Anything that is vulnerable to an oil spill must be classified as a ‘parameter’
Parameter Identification

Accidents at Sea Analysis
"Analysis of Accidents at Sea" includes:
• Collision accidents
• Grounding accidents
• Fire and Explosion accidents
• Ship damage and Foundering due to various causes,
such as hard weather
• Collisions with fixed objects (i.e. offshore structures).
• STS operations
Accidents at Sea Analysis
Collision & Grounding Analysis
Collision and Grounding types of accident are linked
directly with the AIS data analysis and more specifically,
with the position of the vessels and how close they come
to each other. All the other types of accidents are less
important, since collision and groundings account for
95% of the modeling efforts of all the types of accidents.
Moreover, all the other types rely on statistical data only.

Types of Collisions:

Types of Grounding

Collision & Grounding Analysis
TWO OPTIONS FOR ESTIMATING THE PROBABILITY OF
OCCURRENCE-FREQUENCY (RISK ESTIMATION)
Statistical Only
Modeling the Physical process
Collision & Grounding Analysis
Modeling the Physical process
Modeling the physical processes consists of two parts:
a) Geometrical calculations using input data from AIS (lateral
distibution, course over ground, speed, ship length, beam)
b) Statistical parameters (causation probability = 1 - The probability
of making a succesful evasive manoeuvre given that you are on
direct collision corse).
Thus, collision and grounding analysis model does have a statistical
component, but it is only a small part of the model.
Accidents at Sea Analysis
Conclusion
The main part of the ’Analysis of accidents at sea’ is to figure out the
probability (frequency) of a specific accident to occur, that is calculating
the risk probability of a specific accident based on the AIS data and
statistical parameters. And this is done for both collision and grounding
Accidents.
PROBABILITY OF OCCURRENCE = RISK ESTIMATION
Accidental spill of oil Analysis
The main part of the ’Accidental Spill of Oil Analysis is to take into
account the amount of risk calculated in the Accident At Sea Analysis
(probability of occurrence) and find the closest match against
‘collision model scenarios’ with the aim to ‘forecast/predict’ the amount
and type of oil spill at sea.
ACCIDENTAL SPILL OF OIL ANALYSIS = RISK EVALUATION
OVERALL MODEL – RISK ASSESSMENT
ACCIDENTS AT SEA ANALYSIS
= RISK ESTIMATION
ACCIDENTAL SPILL OF OIL ANALYSIS = RISK EVALUATION
DAMAGE IMPACT ASSESSMENT
The damage analysis is used to determine the consequence from
an accidental spill of oil in a uniform way throughout the project
area. The model for environmental damage will be developed
with input from the accidental oil spill analysis and the sensitivity
analysis.
