In addition to the primary requirements of structural strength and function, the critical issues when designing concrete structures for the marine and underwater environment are buildability and durability. Buildability is essential for safety and economy during construction and can have a major influence on the long-term performance of the structure. Durability is influenced by design and by construction methods in addition to the environmental conditions. Understanding concrete technology, the process of construction in the marine and underwater environments and the mechanisms for the degradation of concrete in these hostile environments is necessary if durable structures are to be built. These aspects are discussed, a methodology is outlined and examples are given with reference to the latest British Standards for concrete specification, performance, production and conformity.
