Project Number 263
Date of Summary June 15, 2001
Subject Underwater Welding Development Program, Phase II
Performing Activity Global Divers and Contractors, Inc.
Principal Investigator C. E. Grubbs
Contracting Agency Mineral Management Service
Estimated Completion Complete
Description This is a Joint Industry Project (JIP). The purpose is to develop welding electrodes to make wet welds that will, to the greatest extent possible, meet the requirements for Class A dry welds. This will be done be compensating for pressure-induced changes in weld metal. A realistic goal may be Class A welds to 100 feet, Class B+ (reduced porosity and increased ductility) from 100 feet to 200 feet, and consistent Class B welds to 300 feet.
Progress Project work is complete.
