I occasionally consult, for compensation, to companies about the topics of "hot tapping" and related processes, machinery or pressure vessels; field-applied composites used in the areas of pipeline or structural repair; on-stream leak sealing processes, pressure vessels and sealants; industrial health & safety; general science processes and procedures; general business management.
