Abstract
The objective of the study was to test several bristle
materials, which are designed for arctic brush skimmers,
and find out the possible differences in their
performance with two different oil type and in three
temperatures. Additional objective was to clarify the
possible correlation between the results from Wilhelmy
plate experiments and macro-scale test results. The tests
were performed in the collaboration with VTT and SYKE.
Two test drums from both bristle materials were
manufactured for the macro scale tests, one for marine
diesel oil and one for heavy fuel oil. The design of the
drums and bristles were predefined to enable the
comparison of the results. The test program was two-fold;
in the first phase totally 11 different materials were
tested with the Wilhelmy plate method in order to
determine the surface tension of the particular test oil
with the bristle materials. According to the Wilhelmy
plate measurements, two materials were selected for the
macro-scale tests. The tests were carried out according
to a specific test program particularly prepared for the
macro-scale tests. All the tests were performed without
water or ice, and depending on the oil type and
temperature, each test was repeated 5 or 10 times. The
results indicated that the differences in the oil pick-up
rates were smaller with heavy fuel oil than with marine
diesel oil, and different materials had diverse trends in
the variation of the pick-up rates between the test runs.
In addition, the correlation between the Wilhelmy plate
experiments and the macro scale tests could be observed.
