ABS and Polish Register to extend cooperation

14 Jul 2008

ABS and Polish Register of Shipping (PRS) have announced a multi-year, joint research and development program that will focus on ship dynamic stability in extreme wave conditions and the time variant reliability of aging bulk carriers.
Agreement on the R&D projects follows the conclusion of a wide-ranging co-operative accord that was signed by the two class societies in March. The two societies are already working closely on several dual class newbuilding projects.
ABS president and COO Christopher J. Wiernicki said that these two major research projects would dovetail the strengths of both societies and are expected to result in criteria that will further improve marine safety. PRS president Dr Jan Jankowski noted the increased interest in ship behavior in extreme wave conditions in light of a growing concern that the prevalence of extreme waves may be greater than previously thought.
The multi-phase, multi-year investigation will evaluate the component parts of each society?s existing methodology and simulation software that address issues such as pressures, forces, loads and ship motions, and validate the results against extensive model tests and experiments. Subsequent research will then consider specific issues such as the dynamic stability of smaller vessels, and also the impact on specific components of larger vessels such as the foredeck structure, hatch coamings and hatch covers. The study is also expected to further advance the class societies? understanding of the issue of parametric roll and broaching phenomena.
With respect to bulk carriers, ABS is enlisting PRS assistance in its on-going study into the cumulative, long term effect on the structure of bulk carriers of the increasingly high loading rates at iron ore terminals. The first two phases of the ABS project, carried out with the assistance of Intercargo, have been completed.
Both Wiernicki and Jankowski emphasized that these two projects are just the first steps in what is intended to be a closer technical cooperation between the two societies. "There are several other promising areas of joint research that have been identified," Wiernicki said. "Discussions will continue on how we can craft an effective joint approach to research these. Our focus is on improving our understanding of the reliability of the entire ship structure over its service life."
