Summary

Chapter 3 provides an introduction to the sea loads that act on ship structures, focusing on environment-related and transient loads. A hypothetical but realistic scenario of a loaded voyage of a bulk carrier is presented, and is used to identify and subsequently classify all loads that act on the hull girder. These are classified as environment-related, hull girder-related, mechanical equipment-related and cargo-related. The sources of environment-related loads are then discussed. These include hydrostatic pressure, wave loads, thermal gradients, ice loads, wind pressure and related variations on a geographic and temporal basis. Transient wave loads are then discussed (bottom slamming, bow flare impact and deck wetting), followed by a discussion on springing. The discussion of slamming includes hydroelastic effects. The need for nonlinear analysis in estimating springing and whipping loads is discussed in the last section of the chapter.
