Knowledge of the strength characteristics of docking block timbers is a key element in safely drydocking ships. Such knowledge has become especially important for the Navy, because of changes in Navy ship design, coupled with heightened safety concerns regarding seismic loading. Although, over the years, timber strength knowledge has evolved to a general level, it has never reached the detailed level required to meet todays needs. This paper describes a study to gain timber strength knowledge at the detailed level by testing actual docking block timbers. The tests were conducted on individual timbers, timbers formed into layers, and timbers within full-sized docking block build-ups. The implication of the test results are discussed.
