API 17A provides general requirements and recommendations for the development of subsea production systems, from the design phase to decommissioning and abandonment. This document also references to other API 17-series documents as well as various other relevant industry documents.

The complete subsea production system comprises several subsystems necessary to produce hydrocarbons from one or more subsea wells and transfer them to a given processing facility located offshore (fixed, floating, or subsea) or onshore, or to inject water/gas through subsea wells.

This document, given its broad scope, has a systems engineering section. The purpose of this section is to help ensure consistency across the various subsystems.

If requirements as stated in this document are in conflict with, or are inconsistent with, requirements as stated in other API 17-series documents, then the specific requirements in the subsystems series document(s) take precedence.

This recommended practice (RP) aims to provide operators, contractors and suppliers with guidance on the management and application of reliability and integrity management (RIM) engineering techniques in subsea projects and operations within their scope of work and supply. It is applicable to:

— standard and nonstandard equipment (within the scope of API 17A);

— new field developments, further development of existing fields and field upgrades;

— all life cycle phases from feasibility through design, manufacture, and operation to decommissioning.

NOTE API 18LCM ^[1] gives additional guidance on general requirements for life cycle management of equipment.

This RP is not intended to replace individual company processes, procedures, document nomenclature, or numbering; it is a guide. For example, this RP does not prescribe the use of any specific equipment or process. It does not recommend any actions, beyond good engineering practice. However, this RP may be used to enhance existing processes, if deemed appropriate.

This part provides standardized calculation methods for the determination of meter factors under defined conditions, regardless of the point of origin or destination or units of

measure required by governmental customs or statute. The criteria contained here will allow different entities using various computer languages on different computer hardware (or by manual calculations) to arrive at identical results using the same standardized input data. 

This document also specifies the equations for computing correction factors, including the calculation sequence, discrimination levels, and rules for rounding to be employed in the calculations. No deviations from these specified equations are permitted, since the intent of this document is to establish a rigorous standard.

IEC 61511-2 provides guidance on the specification design , installation operation and maintenance of safety instrumented functions and related safety instrumented system as defined in IEC 61511-1. This standard has been organized so that each clause and sub clause number herein addresses the same number in IEC 61511-1 (with the exception of the annexes).

This International Standard applies to the generation of electromagnetic energy, from sound and television receivers, for the reception of broadcast and similar transmissions and from associated equipment. The frequency range covered extends from 9 kHz to 400 GHz. No measurement need be performed at frequencies where no limits are specified.

This part of CISPR 16 is designated a basic standard which specifies the characteristics and performance of equipment for the measurement of radio disturbance voltage and currents in the frequency range 9 kHz to GHz. Specifications for the ancillary apparatus are included for artificial mains networks, current and voltage probes and coupling units for current injection on cables. The requirements of this publication shall be complied with at all frequencies and for all levels of radio disturbance voltages and currents within the CISP indication range of equipment. Methods of measurement are covered in Part 2 and further information on radio disturbance is given in Part 3 of CISPR 16.

This part CISPR 16 is designated a basic standard , which specifies the manner in which measurement uncertainty is to be taken in to account in determining compliance with CISPR limits. The material is also relevant to any EMC test when interpretation of the results and conclusions reached will be impacted by the uncertainty of the instrumentation used during the testing . Annex A contains the background material used in proving the amount of measurement uncertainty found in generating the CISPR values shown in Clause 4 and hence provides valuable background material for those needing both initial and further information on measurement uncertainty and how to take into account individual uncertainties in the measurement chain. The annex however is not intended to be a tutorial of user manual or to be copied when making uncertainty calculations. For that, the references shown in the bibliography should be used.

This International standard specifies the information to be listed in specification sheets for electrophotograpic digital copying machines and multi-function devices. The intention of this International standard is to allow purchasers and users to compare the characteristics models of copying machines and multi-function devices so that they can more easily select copying machines and multi-function devices that meet their requirements.

Radio communication in which transmissions are intended for direct reception by the general public these may include sound programmes television programmes and other types of transmission.

This international standard applies to single- phase and three phase oil - immersed power transformers including auto-transformer with the exception of certain small and special transformers as defined in the scope of IEC 60076-1 It identifies transformer windings to their highest voltage for equipment Un associated with their corresponding rated insulation levels and details the relevant applicable dielectric tests and minimum external clearances in air between live parts of bushing and to objects at earth potential.
