Due to the development trend of large and ultra-large vessels, port construction is gradually realizing network layout, deep water structure, and business logistics. Fa- cilities such as reinforced concrete and steel structures, such as breakwaters, caissons, intakes, box culverts, and pipe culverts, face the problem of high transportation volume and cost. Some components weigh up to 20,000 tons and involve on-site production transportation services, placing higher technical requirements on engineering service enterprises. MEGAMOVE provides clients with engineering services for component transportation during port and terminal construction. This includes the lifting, transportation, and loading onto ships of movable gantry cranes, SPMT transportation, dry and wet towing to installation locations, and other lifting and integrated land- sea transportation services. Taking into account various aspects such as specialized equipment such as SPMT, semi-submersible ships, deck barges, and floating docks, equipment design, program design, technical services, and on-site implementation, we provide comprehensive solutions for the overall displacement and transportation engineering of components.
