Welcome to the State of California, Prison Industry Authority

Marine Technology Training Center

The California Prison Industry Authority (CALPIA) operates the Marine Technology Training Center, an 11-month training program, providing training in diverse curriculum including diving physics, navigation, report writing, air systems, welding, seamanship, blueprint reading, diesel engines, and marine construction. The training not only focuses on technical skills, but also instills a professional attitude of determination, perseverance, and courage. Together, these skills provide graduates with employment opportunities in commercial diving in areas such as underwater construction, dam repair and maintenance, welding, harbor diving, and offshore oil drilling.

On December 1, 2006, CALPIA re-established the commercial diving center at the California Institution for Men (CIM) in Chino as part of the renewed rehabilitation efforts of the California Department of Corrections and Rehabilitation.

The Marine Technology Training Center (MTTC) has a renowned history of not only educating and training inmates as commercial divers, but also of providing inmates with the confidence needed to successfully transition into meaningful employment and avoid re-incarceration.

The commercial diving program was initially established in 1970 at CIM, under the vision and guidance of Leonard Greenstone, Vice Chair, Prison Industry Board Member, former U.S. Navy salvage diver and successful commercial diving contractor. This successful commercial diving, with the graduates consistently maintaining a recidivism rate as low as 6 percent, ended in in 2003 because of budget constraints.

The technical skills learned at the MTTC are designed to ensure that nearly 100 percent of the program's graduates secure jobs after release. The training modules also focus on helping the graduates in adjusting and developing proper attitude, initiative, and industrial skills.

Program Goals

  • The MTTC has expanded from just producing commercial divers, to training inmates in other occupations in the marine industry. The training courses prepare inmates for all forms of employment opportunities in the marine technical fields, as well as preparing inmates to become productive members of society.

Values to Inmates

  • Marine-related technical work is most appropriate for the lifestyle of inmates who are courageous and enjoy challenging types of work. The training provides inmates with internationally certified and recognized skills that are readily transferable to well-paying jobs upon parole.

Program Curriculum and Certification

Classes offered by the MTTC are diversified to meet the interests and abilities of the individual inmates. All inmates are required to master classes in general education, physics, physiology, dive medici nine, proper tool handling, blueprint reading, and seamanship. The classes in various programs include welding and cutting, all phases of operations and repair of diesel engines, compressors, pneumatic tools, rigging, marine construction, power plants, and pump houses.

  • Bridge Repair and Maintenance, (R&M)
  • Wharf and Pier Construction, (R&M)
  • Underwater Non-destructive Testing, R&M of steel structures
  • Commercial Diving/Inland and Offshore.
  • Underwater Salvage & Recovery
  • Underwater Remote Control Vehicles
  • Hyper baric Chamber Operations
  • Boom and Environmental Pollution Control in U.S. ports
  • Underwater Welding & Burning

The certifications for successful graduates will meet the standards required by U.S. Coast Guard, Department of Labor (OSHA), and the Association of Diving Contractors International.
