Detection of surf-riding behavior of ships in irregular seas

Nonlinear Dynamics, 2014
From investigations with ship models tested in steep periodic following waves, it has been conjectured in the past that, if the speed is observed reaching (in transient) the celerity value, attraction toward the condition commonly identified as “surf-riding” is already in progress.

Surf-Riding Operational Measures for Fast Semidisplacement Naval Hull Form

, 2020
Surf-riding/broaching failure mode is one of the Second Generation Intact Stability Criteria (SGISC) dealt by IMO. The SGISC are structured with a multi-tiered approach: Level 1, Level 2 and Direct Stability Assessment (DSA). When a ship does not verify one level, the next once must be applied, or the ship design must be modified.

Improved prediction of the threshold of surf-riding of a ship in steep following seas

Ocean Engineering, 2010
Abstract An extended version of Melnikov's method is implemented in order to predict more accurately the threshold of global surf-riding for a ship operating in steep following seas. The key advantage of the proposed method is that it overcomes the limitation of small damping and/or small forcing that are intrinsic to the implementation of the ...

Application of surf-riding and broaching criteria for the systematic series D models

Ocean Engineering, 2018
Abstract The Second Generation Intact Stability Criteria (SGISC) have been introduced after the occurrence of stability-related accidents, which clearly demonstrated that “actual” intact stability criteria were not adequate. New generation criteria are based on the physical and failure mode analysis of parametric roll, pure loss of stability, surf ...

Vulnerability assessment of surf-riding-broaching and pure loss of stability for Systematic Series D1 model

Ships and Offshore Structures, 2019
This paper is focused on the first and second level vulnerability assessment of Surf riding/Broaching and Pure Loss of Stability Criteria according to IMO second generation intact stability criteria.

Surf-riding model for cell capping

Journal of Theoretical Biology, 1979
Abstract A model is proposed for cell capping which postulates that progressive waves on the surface of motile cells are the inducers of movement of membrane bound particles and macromolecules. First order calculations are performed which indicate that a large particle will be entrained by waves more readily than a small one; this corresponds with ...

Riding the Wave: History, Definitions, and a Proposed Typology of Surf-Riding Tourism

Tourism in Marine Environments, 2012
Surfing has evolved from a fringe counterculture recreational activity to a multibillion dollar global industry with a diverse range of equipment and millions of participants. The growth and influence of surfing, in its myriad of forms, has not been widely researched and is scarcely reported in the academic literature. This article reviews the history

Successful surf-riding on size spectra: the secret of survival in the sea

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1994
Abstract All ecosystems require constituent species to survive against a backcloth of biotic and abiotic scenery. How this scenery shapes the life-history strategies of the players and how they in turn shape the scenery are important themes of the play of life.
