Work environment
Project-based work, often close to shore, port-frequent. Crews rotate on 4-on/4-off or 6-on/6-off depending on operator. Major employers: Boskalis, Van Oord, Jan De Nul, DEME, China Communications Construction (CCCC). Strong land-reclamation demand in Middle East and Asia keeps the fleet busy year-round.
