PDI is a member of the Association of Diving Contractors International (ADCI) and endeavors to promote the highest possible level of safety while providing diving services. PDI conducts job safety analyses for each service provided, requires personal protective equipment (PPE) at all times, and its dive supervisors conduct pre- and post- safety meetings. Equipment is routinely checked, then staged and tested prior to each job.

PDI follows the ADCI Consensus Standards for commercial diving and underwater operations. Operational and Health and Safety Procedures have been reviewed, updated, and documented through the below documents:

  • Pacific Diving Industries Inc. Safe Operations Manual
  • Pacific Diving Industries Inc. Health and Safety Program
  • Pacific Diving Industries Inc. Quality Management Systems Manual

PDI has an exemplary safety record. There has been no lost time in the past seven years.

Performance Standards

PDI has written procedures for services provided (i.e. hull and propeller cleaning, NDT testing, and UWILD surveys under the direction of a surveyor). The NavSea Underwater Ship Husbandry Manual is used for services such as Cofferdam Installation and Shaft Wraps. All work is carefully planned and discussed with PDI’s general manager, dive supervisor, and the ship’s chief engineer.

The Company’s capabilities in marine construction include: the installation of several of Hawaii’s small boat marinas; bridge, pier and pile repair for the U.S. Navy, Air Force, and Coast Guard in Hawaii, Wake and Midway Islands; buoy & mooring maintenance and installation for the State of Hawaii; ultrasonic testing and maintenance of pipelines for the U.S. Coast Guard; extensive work on the OTEC-1 project for the U.S. Department of Energy, including inspections, rigging, underwater welding, and installation of mooring facilities; and surveying suitable undersea routes for cable laying ships.

Equipment & Location

PDI’s Honolulu facility is in Mapunapuna, conveniently located to Honolulu and Pearl Harbors and a short drive from both the airport for travel to outer islands and the west shore harbor facilities at Barber’s Point.

In Mapunapuna, PDI has a spacious shop that houses the diving equipment (scuba and surface supplied), an air compressor for on-site tank filling, portable air compressors, hull cleaning equipment, welding and cutting equipment, a stock of anodes, cofferdams, rigging, lift bags and dive related items. There is a separate office on-site for administration.

PDI uses pneumatic (air-driven) hull cleaning machines that can be fitted with a variety of
brushes depending on the intensity and density of bio-fouling present and the type of hull coating. These machines are efficient and eliminate the risk of oil pollution to the water.

The Company’s main transportation vehicle serves as a “drive and dive” set up containing the surface air supply equipment and a station that houses video graphic and through water communication equipment. This increases operational efficiency and facilitates a real-time viewing and recording area for our clients.
