Ken Arnold, NAE, contributed greatly to the responsible development of offshore oil and gas resources. Among Ken’s achievements – lead engineer for a major offshore operator, entrepreneur who founded a successful engineering and management company, author of production textbooks, distinguished SPE lecturer and university instructor, NASEM Marine Board member, and safety leader who participated in the development of OCS regulations and standards.

Ken explains how his new engineering company was involved in the Gulf’s first “Rigs to Reactors” initiative:

My first job as Paragon Engineering Services was to advise Westinghouse on the ability of their yard in Jacksonville, FL to fabricate offshore jackups. 

They had built a total facility with acres under roof, a huge drydock, and the biggest gantry crane in the US to fabricate large nuclear reactor vessels which stood on top of a barge hull which contained all the equipment necessary for a power plant.  They had an order for, I think, 12 of these units.  The plant was designed to complete one a year through an assembly line type of process.  The facility was approved by Nuclear Regulatory Agency, and others.   The piping model of the barge hull (this was in 1980 before we had 3-D models and large complex facilities were often constructed in scaled plastic) had a footprint as big as my house.

The goal was to make identical units which would be floated to a shore-based site where it would be sunk and protected from waves, etc.

Then came Three Mile Island and all orders were canceled.

Ken recalls further:

They eventually decided not to get into the rig fabrication business. The only thing I know of which was ever fabricated in the huge fab building was some cars for a ride at Disney World. I drove by the site many years later and the gantry crane was gone and it had been turned into a container port. I am not sure what happened to the huge drydock.

Note the unique MMA logo! 😉

MMA and NRC signed an MOU (attached) to strengthen cooperation on potential nuclear projects on the OCS. Nuclear power has been on the alternate use list (Rigs-to-Reefs+++) from the outset, so this is pretty exciting. Challenges and opportunities!

“Submerged reactor systems have been safely deployed in naval applications for decades, demonstrating their potential as a reliable source of energy in demanding marine environments. While no commercial deployment on the Outer Continental Shelf is planned or approved at this time, it could greatly strengthen America’s energy security in the future,” said MMA Acting Director Matt Giacona. “With nearly 3.2 billion acres of the Outer Continental Shelf under federal jurisdiction, this MOU is an important step toward building the technical expertise, regulatory clarity, and interagency coordination needed to assess whether and how this technology could be responsibly implemented in the years ahead.”
