Three methods of presenting wave data are discussed: the significant wave (including the "design wave" concept), the wave spectrum, and the directional spectra. Their use in calculating wave forces on pile supported structures is described, with a discussion of the relative usefulness of the linear versus the non-linear approach. The concept of...

It is described why, and to what extent the practicing engineer makes use of model tests in his design of rubble mound breakwaters. Furthermore an example is shown from practice illustrating the application of models for investigation of wave penetration into harbours. Especially the way in which model tests can confirm and supplement...

This memorandum proposes a mathematical approach of the interactions between a non-viscous fluid with a free surface and an assembly of structures composed of shells, whether fixed or not, partially or totally immersed in the fluid. Some fundamental aspects of the problem, such as the effects of the free surface and of the mutual influence of...

Until after the second World War, the ocean was regarded by the oil industry only as a cheap means of transportation. Before the war some timber structures very close to the shoreline had been constructed, but drilling for oil on the continental shelf did not really start until 1947, when the first steel platform was erected in 20 ft. of water...
