Soon the ship will travel to sea, where an automated hammer will drive the pipes into the ocean floor to support wind turbines. “Everything in our industry has become larger,” says Koen Vanderbeke of DEME, a Belgian dredging firm that owns the ship. “But we’ve become smarter, too.”

Unlike their counterparts on dry land, marine contractors have made big leaps in productivity in recent years. From dredging and land reclamation to offshore construction of oil platforms, costs have dropped even as the speed and quality of work have increased. In Belgium, home to two of the world’s five biggest dredgers, efficiency gains have been so large that they have skewed productivity figures for the entire building...Continue reading
