ISO 19859:2016

• Abstract:

  ISO 19859:2016 specifies the minimum technical and documentation requirements for the evaluation and procurement of gas turbine systems for electrical power generation. It applies to simple cycle and combined cycle gas turbines for both onshore and offshore applications, where applicable. It also applies to gas turbines used in cogeneration (see ISO 11086:1996, Annex B). Testing of the gas turbine in combination with a generator is included in the scope. It is not applicable to gas turbines used for all types of propulsion including aircraft, mobile barges, floating production vessels and marine propulsion applications and microturbines. ISO 19859:2016 defines the requirements for gas turbine power generation from an international perspective based on the content of existing, recognized ISO and IEC standards to the greatest extent practical. Nonetheless, it is recognized that within the industry other codes or standards are used, some of which are included in the text of this International Standard. The use of other such codes and standards is permissible provided an appropriate and acceptable level of requirements, functional design and safety is achieved and agreement has been reached for their use between the Purchaser and Contractor and such use is suitably documented. Consideration should be given to applying/using standards in the following hierarchical order: international; regional; national; local. ISO 19859:2016 identifies the requirements for both the Purchaser and Contractor attributable to the design and procurement of a gas turbine power generation package. The defined requirements apply to the scope of supply, except where excluded, encompassing the following equipment and the associated selected options, located within the power generation package, (see 3.14), listed below: - gas turbine package; - load shaft coupling and clutch, as applicable; - air inlet system; - exhaust system; - fuel equipment; - control equipment; - electrical equipment; - additional auxiliary systems, including starting, lubrication, barring, compressor wash, pipework, drains and vents; - fire and gas protection; - cooling water equipment. Where applicable to the integrity of the gas turbine package, the interface and applicable design requirements are included for equipment, utilities and supplies that interface with the power generation package. The following equipment is excluded from the scope of supply, but references are included where required for interface or performance measurement: - generator and auxiliary systems, except the module control option; - steam turbine and auxiliary systems; - equipment external to the power generation package. Data sheets in Annex A of this International Standard are provided for defining requirements and exchanging information between the Purchaser and the Contractor. The Purchaser fills in the data sheets for the tender and forwards them to the Contractor. The Contractor responds by completing the applicable data sheets for their tender. Annex A identifies the different types of data sheets and how they are to be used. Where the Contractor does not comply with a selected requirement of this International Standard, this is detailed as an exception, referencing the applicable clause and describing the deviation and any alternatives available in a document listing all the exceptions taken. Where the text in this International Standard requests procedures and operating, maintenance and commissioning manual information or equipment that would require the disclosure/supply of proprietary information/equipment which the Contractor is not prepared to release, such exceptions are listed. Where this situation exists, the Contractor will be prepared to release appropriate personnel and equipment to undertake all the tasks that otherwise would be undertaken by the Purchaser. A bullet ● at the beginning of a paragraph in the text of this International Standard indicates an optiona

Overview

ISO 19859:2016 - Gas turbine applications - Requirements for power generation is an international standard that defines the minimum technical and documentation requirements for evaluating and procuring gas turbine systems used for electrical power generation. It covers both simple cycle and combined cycle gas turbines for onshore and offshore installations and includes testing of the gas turbine in combination with a generator. The standard is intended to harmonize purchaser and contractor responsibilities and to reference recognized ISO/IEC and other industry codes where practical.

Key topics and technical requirements

ISO 19859:2016 addresses the full lifecycle and interface requirements for a gas turbine power generation package. Major technical areas include:

• Scope of supply and interfaces

  • Defines equipment within the power generation package (gas turbine package, air inlet, exhaust, fuel, controls, electrical and auxiliary systems, fire/gas protection, cooling water).
  • Identifies excluded items (generator and its auxiliaries except module control option, steam turbines, external equipment) and interface responsibilities.

• Performance and testing

  • Comparative performance assessment at standard reference conditions and site conditions, including site rating, net heat rate, minimum load and peak load.
  • Testing requirements when the turbine is combined with a generator.

• Site conditions and utilities

  • Requirements for ambient air, water and steam quality, purge media, interface and orientation due to site constraints.

• Emissions and environmental

  • Design philosophy and requirements for preventing unplanned fluid release, exhaust emissions, noise measurement, visible plumes, and emission monitoring.

• Fuel and fuel systems

  • Contract fuel definitions, fuel composition, alternative fuels (syngas, LNG, high hydrogen fuels), fuel supply and treatment, metering, purge and filtration.

• Operation, quality and reliability

  • Operating limits, start/stop cycles, grid requirements (frequency response, island/black start), project quality management, reliability/maintainability and documentation.

• Procurement documentation

  • Annex A data sheets for tendering: purchasers complete and forward to contractors; contractors respond with compliance or documented exceptions.

Practical applications - who uses this standard

ISO 19859 is used by:

• Utilities, independent power producers (IPPs) and plant owners specifying gas turbine purchases
• OEMs, EPC contractors and system integrators preparing proposals and designs
• Procurement teams and contract managers for tendering and supplier evaluation
• Commissioning, operations and maintenance teams for acceptance testing, documentation and performance verification
• Regulators and consultants assessing compliance with international design and environmental requirements

Related standards

• ISO 11086:1996 (cogeneration) - referenced for cogeneration applications
• Existing ISO and IEC standards and recognized national/regional codes - ISO 19859 is intended to align with these where practical; users should apply standards in hierarchical order: international → regional → national → local.

Keywords: ISO 19859, ISO 19859:2016, gas turbine power generation, procurement, performance assessment, fuel systems, emissions, combined cycle, simple cycle, onshore, offshore, cogeneration.
