Accuracy of Visual Wave Observation from Merchant Ships and Estimated Wave Loads

Occupational accidents aboard merchant ships.

OBJECTIVES To investigate the frequency, circumstances, and causes of occupational accidents aboard merchant ships in international trade, and to identify risk factors for the occurrence of occupational accidents as well as dangerous working situations where possible preventive measures may be initiated. METHODS The study is a historical follow up on occupational accidents among crew aboard D...

Definitions for Autonomous Merchant Ships

Hospitalisations among seafarers on merchant ships.

AIMS To study morbidity among active seafarers in the merchant navy in order to clarify possible work related morbidity and the morbidity related to work and lifestyle where possible preventive measures may be initiated. METHODS From a register in the Danish Maritime Authority a cohort of Danish merchant seafarers who had been actively employed at sea in 1995 was identified. For each seafarer...

Waves, damped wave and observation

This talk describes some applications of two kinds of observation estimate for the wave equation and for the damped wave equation in a bounded domain where the geometric control condition of C. Bardos, G. Lebeau and J. Rauch may failed. 1 The wave equation and observation We consider the wave equation in the solution u = u(x, t)    ∂ t u−∆u = 0 in Ω× R , u = 0 on ∂Ω× R , (u, ∂tu) (·, 0) = (u...

Design Aspects of Survivability of Surface Naval and Merchant Ships

The paper addresses various design aspects of survivability for surface naval and merchant ships through a common rational probabilistic methodology. It is based on earlier work of Kurt Wendel on a probabilistic approach to the damage stability of surface ships. This method was adopted by SOLAS 1974 through Res. A.265 (VIII) as an alternative to the deterministic SOLAS criteria for passenger sh...
