Despite its great theoretical and practical importance, the statistical distribution of crest heights has remained poorly known. The uncertainties are due to difficulties both with the theory, where nonlinear effects must be accurately modeled, and with measurements, where different sensors appear to give different results. In response to this unce...

Analysing investment drivers in fisheries is essential in understanding the long-term development of fishing capacity. This paper addresses the drivers of investment in the French commercial fishing fleets operating along the Atlantic coast, and the role of public policies have had on investment. First, we examine the changes in the capital value o...

Thirty French fleets fishing primarily in the Bay of Biscay were defined based on techno-economic input criteria: i) 18 fishing gear or gear combinations ii) the location of fishing grounds visited during a year (<12 nautical miles from coast, beyond 12 nm or both) and iii) total vessel length (<20 m for trawlers and other gears <24 m). The fleets...

The wavelength is an important quantity in a number of ocean-engineering applications, e.g. for design of structures that have dimensions of the same order of magnitude as the wavelength. Most often however, the description of the wave climate is given by a spectrum. We present a methodology based on a representation of a sea state in the frequency...

We present a method for the estimation of the distribution of the quasi-static hogging-bending moment for a floating body. Start-ing points of this study are temporal characteristics of the sea state. The approximation is deduced from the estimation of the joint distribution of crest amplitude and crest length. The qual-ity of the model is investig...
