Timber is still an important construction material in many small and medium-size marine structures owing to good properties with respect to strength, toughness, elasticity/resilience, weight, shaping, and cutting. The PIANC WG31 revised the PIANC WG17 report with the title “Inspection, maintenance and repair of maritime structures exposed to material degradation caused by a salt water environment”, and published the revision in 2004. In the revision, the chapter of timber was rewritten based on the data from foreign countries. In this report, the outlines of the degradation, inspection, maintenance and repair of timber in a marine environment are presented in reference to the revision.
