Capabilities Project management Project management capabilities have enabled Dril-quip to better manage the design, manufacture and delivery of Dril-quip products on large, integrated projects throughout the world.

3 The project management techniques utilize time-proven proc- esses, which are defined at the start of a project via a formal Project Execution Plan (PEP). This formalized project management system has proven invaluable for successful management of the resources necessary to complete projects on time and to the customers' requirements. Engineering Dril-quip's technological leadership in the industry is the result of an ongoing commitment to a professional engineering staff with in-depth experience in the design of Drilling and Production equipment. This experience is supported by state-of-the-art computer systems networked to expedite and optimize the process of modeling, analyzing, modifying and testing each design. These capabilities enable Dril-Quip to consistently provide new and improved products to the oil and gas industry worldwide. Manufacturing Dril-quip products are manufactured from selected high-grade forg- ing material. Computer Numerically Controlled (CNC) machine tools are used for dimensional accuracy, precision machining and consist- ent quality.

4 Each product is inspected, assembled and tested prior to shipment. Computer tracking systems are used to schedule and monitor each customer's order during the manufacturing process. This attention to detail ensures product quality and on-time delivery. Service In order to ensure vital support to the offshore industry, Dril-quip field service technicians are rigorously trained and tested in the proper use, handling and repair of Dril-quip products. Only the most qualified and knowledgeable personnel are employed by Dril-quip for field service. These technicians are then posted at strategically located Dril-quip facilities throughout the world, readily available to our customers on a 24-hour basis. Training The Dril-quip Training Department offers to the industry training courses in the installation, operation and maintenance of offshore Drilling and Production equipment. These courses utilize computer- assisted training tools, models and actual equipment to enhance the participants' knowledge of offshore operations.

Spars and Tension Leg Platforms (TLPs) are floating Production vessels that serve as host platforms for the Production subsea wells. These vessels can feature top-tensioning Drilling and/or Production riser systems that are attached to subsea wellheads di- rectly beneath the vessel on the ocean floor. Each well is completed at the surface with a surface Production tree. Spars and TLPs can also serve as host platforms for ocean floor field developments that are tied back to the floating Production vessel with flow lines. Each well , in this case, is completed at the ocean floor with a subsea tree, and then funneled through a mani- fold to the floating Production platform.
