2. 1. INTRODUCTION
1.1 RESEARCH BACKGROUND
O’conneli (2006) stated that oil pollution affects on :

Fisheries and aquaculture resources ,

Tourism and,

Costal industries
In this research:

It is essential to predict the oil fate and slick trajectory

Combating strategies need to be set

Through simulation

3. 1.2 PROBLEM STATEMENT
Oil pollution control strategies need to be
developed for each oil fate and slick trajectory
scenario. Since each scenario is unique and
independent, simulation method is preferred.

4. 1.3 OBJECTIVE
To develop a method of choosing oil pollution combating
strategies

5. 2. LITERATURE REVIEW
i.
Oil fate; The most important processes are spreading, evaporation, dispersion
viscosity and emulsification (O’connel, 2006c).
ii.
Slick trajectory; When an oil slick is predicted to affect on high sensitive
area, this prediction helps the decision maker significantly to choose the
combating strategies.
iii.
Types of shorelines; according to geographical shape, types of beaches
and to the environmental and socio-economic activities (IPIECA 2008a).
iv.
In-hand equipment and combating strategies; the limitation of spill control
techniques must be taken into consideration in determining the most appropriate
clean up response (Persga, 2009a). All of on-scene commanders are allowed to
take whatever action is appropriate to clean up and/or mitigate the effects of an
oil spill (Ch'ng,1997).

The remained 300 m3 of oil and emulsion reached
next to tidal zone and might be scattered along the
shoreline and went into part of Johor strait.
The recovery of collected oil in the deployed
protection booms areas depend upon instant
findings and ought to be done by using oleophilic
skimmer, Shore and harbour weir skimmer

 Protection of the most environmental and economical sensitive areas such
as Tanjung Pelepas Port, Tanjung Bin steam power, most of the mangrove
shoreline up to Puteri Habour was based on prediction of the slick
trajectory.
 Large quantity of contaminate was accumulated next to the protection
booms which led to make shoreline clean-up and recovery easier and faster.

45. 5 CONCLUSION


marine oil pollution control strategies to reach highest environmental and
economical benefit in south east of Johor.

