Introduction

GB/T 14099 "Gas Turbine Procurement" aims to clarify the requirements for procuring gas turbines, including combined cycle systems and their auxiliary equipment.

Technical information. GB/T 14099 is proposed to consist of the following parts.

---Part 1: General Provisions and Definitions. This section aims to define the terms and definitions relevant to the procurement of gas turbines.

---Part 2: Standard Reference Conditions and Ratings. The purpose is to specify the standard reference conditions and ISO standard ratings for gas turbines.

A constant value.

---Part 3: Design Requirements. The purpose is to specify the design requirements for the gas turbines and auxiliary equipment to be procured, providing a basis for the procurement process.

Related technical information support.

---Part 4: Fuel and Environment. The purpose is to establish guidelines and provisions regarding fuel quality and environmental requirements in gas turbine procurement.

Required information.

---Part 5: Applications in the Oil and Gas Industry. The aim is to provide information on gas turbine applications in the oil and gas industry.

Provide guidance on design, materials, manufacturing, inspection, testing, and transportation preparation.

---Part 7: Technical Information. The purpose is to clarify the delivery requirements for technical documentation during the gas turbine procurement process.

---Part 8: Inspection, Testing, Installation and Commissioning. The purpose is to provide inspection, testing, and installation services for gas turbines and their complete systems.

And guidance on debugging.

---Part 9: Reliability, Availability, and Maintainability. The purpose is to specify the reliability, availability, and maintainability of gas turbines.

The content facilitates communication and exchange among gas turbine manufacturers, users, consulting firms, regulatory authorities, insurance companies, and other entities.

It provides information on the reliability, availability, and maintainability of gas turbines.

The formulation of this document can standardize the procurement process of gas turbines and ensure the performance and quality of gas turbines.
