Sea Engineering Inc., was contracted by the State of Hawaii Division of Boating and Ocean Recreation (DOBOR), DLNR to redesign the mooring layout and mooring assembly design for Keauhou Bay, Hawaii. The purpose is to more effectively accommodate vessels and improve mooring assembly design and vessel and user safety.

The work included the following:

  • Detailed site investigation to map existing moorings and bottom composition
  • Design of a gravity mooring anchor system suitable for the variable, rocky, rubbly substrate in the bay
  • Design of a mooring layout that maximizes vessel capacity in a safe manner
  • Acquisition of a Department of the Army permit for the mooring buoys

In total, the proposed moorings will accommodate 14 vessels ranging from 30 to 60 feet in length. Mooring locations have been selected to avoid areas with high benthic marine life as far as practicable.
