For the second time in three years, ISOPE rewarded Laurent Brosset, Technical Expert in the Liquid Motion Department at GTT, with the Best Paper Award, for his contribution to the article  “Elementary Loading Processes (ELP) involved in breaking wave impacts: findings from the Sloshel project”.

The International Society of Offshore and Polar Engineers (ISOPE) gathers every year hundreds of engineers and researchers for a conference composed of several symposia mostly related to marine engineering.
ISOPE is one of the most important technical conferences, along with OMAE, on this domain. What makes it particular is its special symposium dedicated to sloshing.

GTT has participated actively in every conference since the first one including a sloshing symposium, which was held in Osaka in 2009.

Each conference ends with a rewards ceremony, including the best conference paper of the previous year. On July 3rd, this prize was awarded to Wim Lafeber (MARIN), Hannes Bogaert (MARIN) and Laurent Brosset in Anchorage (AK, USA). The paper was selected from a total of 645.

“Elementary Loading Processes (ELP) involved in breaking wave impacts: findings from the Sloshel project” shows that all wave impacts generate loads in time and space domains, which are always made of the 3 same elementary components (Elementary Loading Processes or ELPs). This result is illustrated thanks to experimental data (mostly pressure measurements and synchronized high speed videos recording the shape of the waves during impacts) obtained during wave impact tests in the Delta flume of Deltares (NL), at the time of the Joint industrial Project Sloshel.

The first ELP appears at the first contact point between the free surface and the wall. It is related to the propagation of a pressure wave throughout the liquid. The second ELP basically corresponds to the hydrodynamic load. The third ELP is associated to the gas compression either when the gas escapes during the wave approach or when it is entrapped in pockets in between the liquid and the wall.

This decomposition of the loads due to liquid impacts helps understanding the scaling effects, which is essential in the study of sloshing essentially based on small scale model tests.
