Surf‐Riding Threshold of Ships in Random Seas [PDF]
PAMM, 2013 AbstractA possible stability failure in ship dynamics is surf‐riding of the ship in waves followed by broaching‐to. In order to exclude broaching one thus seeks to prevent the ship from surf‐riding. We analyze the surf‐riding problem of a ship in random seas as a weakly perturbed Hamiltonian system, where the excitation owing to irregular sea waves is ...

Comparative analysis of surf-riding characteristics between waterjet and propeller-propelled ships
Zhongguo Jianchuan YanjiuObjectiveSurf-riding, often followed by broaching, is one of the five stability failure modes defined in the IMO's Second Generation Intact Stability (SGIS) framework and poses a significant safety risk to high-speed craft.

Hydrodynamic Aspects on Vulnerability Criteria for Surf-Riding of Ships
Jurnal Teknologi, 2014 For developing the International Maritime Organization (IMO) second-generation intact stability criteria regarding broaching, draft vulnerability criteria for surf-riding were agreed at the IMO in 2012. This paper describes their hydrodynamic backgrounds with captive model experiments for seven ships, a hydrodynamic theory and a random process theory ...

SURFS: Riding the waves with Synthetic UniveRses For Surveys [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We present the Synthetic UniveRses For Surveys ({\sc surfs}) simulations, a set of N-body/Hydro simulations of the concordance $Λ$ Cold Dark Matter (\LCDM) cosmology. These simulations use Planck cosmology, contain up to 10 billion particles and sample scales & halo masses down to $1~$kpc & $10^8{\rm M}_\odot$. We identify and track haloes from

‘Competitors in the surf-riding contest’: battle as theme in the first three surf novels
, 2021 In surf fiction it is common for wave-riders to be tested. The test of self – battling against nature, against others, and against one’s own capabilities – is a popularthematic pathway for discovery, growth and freedom, as manifested regularly in surf ...

An Investigation about Stability in Waves of Large Pleasure Yachts
Journal of Marine Science and Engineering, 2023 The IMO’s second-generation intact stability criteria (SGISc) have been applied to a set of seven megayacht units ranging from 40 m to 80 m. The application aims to evaluate their stability performance in a seaway.

Statistical Correlations of Ship High-Run with Broaching-to and Capsize
Journal of Marine Science and Engineering, 2020 In the current paper we are extending our earlier work on the assessment of a ship’s tendency to capsize due to broaching-to in a stochastic seaway. Capturing, in a probabilistic context, interferences between different phenomena occurring during ship ...
