Maritime structures are engineered facilities built in or near water bodies to support various activities. These include ports, harbors, docks, and piers, which facilitate the loading and unloading of ships. They are designed to withstand harsh marine environments and are crucial for trade and transportation. In addition to commercial uses, maritime structures can also include lighthouses and buoys, which aid navigation and ensure safety at sea. These structures often require specialized materials and construction techniques to resist corrosion and wave action, making them vital for both economic and safety purposes in maritime operations.
