This semi-relieved shipbuilding drydock with tied back steel pile walls has recently been completed on San Diego Bay. Pressure relief is accomplished by cutoff walls and an underdrain system with continuous pumping. Substrata pressure is monitored by piezometers set in deep pipes with remote reading dials at the surface. The underdrain system is separate from the main dock dewatering system. The gate is floated by dewatering flotation chambers with compressed air.
