Fiberspar Spoolable Products, Inc. 1995 to 1999
Consultant
Quality Assurance Manager -
Product Line Manager – Line Pipe

Engaged as a consultant to identify markets and applications for spoolable composite piping products. My market research became the basis of the company business plan. Became a direct employee in January 1996 to help develop and commercialize spoolable composite piping products. Spoolable pipe production involves a continuous filament winding process. Other processes used in the factory include pultrusion, RIM and secondary operations such as sanding and finishing.

· Led the Quality team in documenting the ISO 9001 system, co-ordinated the ISO pre-audit and QA/QC functions for the spoolable composite pipe business. Assisted in limited instances with sporting goods quality issues.
· Used extensive background with standards and regulatory agencies to prepare the Product Development Specification for all spoolable products (there are no accepted industry standards for spoolable composite pipe.). These specifications provided guidance for engineering and manufacturing in developing processes and qualification of the products. Allowed product development with minimal time loss.
· Developed and tested a metallic flush outside diameter connector for use on the first composite coiled tubing installations. Assisted in development of compression type fittings for general applications.
· Participated in material selection, process improvements and evaluation of outside vendors / opportunities.
· Part of a two-person team that developed the marketing strategy for the line pipe products line, all associated literature, advertisements and catalogs. Participated in North American sales efforts.

· P&L Responsibility for an instrument design and manufacturing operation that developed speciality instruments (torque & torque-turns monitors) for running tubing and casing.
· Led the effort to reduce the manufacturing costs and improve the quality of existing designs. Power Tong manufacturing costs were reduced by more than 35% while improving quality and interchangeability.
· Led in an effort to develop new cementing tools that included developing test methods and standards that led to development of an industry (API) standard. New tools included cement shoes, stage cementing tools, and inflatable packers.
· Managed two laboratories on separate sites. One performed evaluation of various casing and tubing running tools and procedures and the other was used to evaluated down hole cementing tools.
· As a part of a two-person team - taught the technical portion of the Mobil Oil Casing and Tubing Running and Handling course for three-years. This was a two-day course available three-four times a year that reviewed the technical aspects of running and handling casing and tubing and the tools required. Taught other (in-house and customer) seminars on various tools and operations on an international basis.
· Assisted international Weatherford operations with development of new tools, processes and quality issues.
· Led in development of a "standard Maintenance Manual" to support rental services
· Presented international training seminars
