Standards

Part 4-41 pf IEC specifies essential requirements regarding protection against electric shock. Including basic protection (protection against direct contact) and fault protection (protection against indirect contact) of persons and livestock. It deals also with the application and co-ordination of these requirements in relation to external influences.

This Part 1 of International standard IEC 50598 specifies general requirements for luminaires incorporating electric light sources for operation from supply voltages up to 1000V. The requirements and related tests of this standard cover, classification , marking , mechanical construction and electrical construction .

This technical report presents an overview and guidance for the IEC 61158 series. IT explains the structure and content of IEC 61158, shows how to use it in combination with IEC 61784, and relates the structure to the ISO/IEC 7498 OSI basic reference model.

This action of IEC 1241-2 specifies two last methods for determining the minimum ignition temperatures of dust. The methods are not suitable for use will having explosive properties.

In addition to the scope of International standard IEC 61326-1, this part specifies minimum requirements for immunity and emission regarding electromagnetic compatibility for in vitro diagnostic medical equipment equipment, taking into account the particularities and specific aspects of this electric equipment and their electromagnetic environment.

This part of IEC 61508 contains information and guidelines on IEC 61508-2 IEC 61508-3 - Annex A gives a brief overview of the requirements of IEC 61508-2 and IEC 61508-3 and sets out the functional steps in their application.

This part of IEC 61606 specifies the basic measurement methods of a linear PCM signal for an audio part of personal computers (PCs) and applies to both desktop and portable computers. The common measuring conditions and methods are described in IEC 61606-1 specific conditions and methods of measurement for PCs are given in this standard.

This clause of Part 1 is replaced by the following. This International standard deals with the safety of electric fans for household and similar purposes, their rated voltage being not more than 250V for single-phase appliances and 480 V for other appliances.

1 Scope 1.1 Coverage The purpose of this document is to recommend practices and procedures for promoting and maintaining safe and healthy working conditions for personnel in drilling and well servicing operations.

1.2 Applicability These recommendations apply to rotary drilling rigs, well servicing rigs, and special services as they relate to operations on location. It is intended that the applicable requirements and recommendations of some sections of the document be applied, as appropriate, to other sections. The recommendations are not intended to cover seismic drilling or water well drilling operations. These recommendations do not apply to site preparation and site remediation operations.

1.3 Responsibility Employers have the responsibility to identify, communicate, and mitigate hazards at the work site. A process of risk assessment may be an effective method to protect employees at the work site.

This recommended practice (RP) provides guidance for floating system integrity management (FSIM) of floating production systems (FPSs), which include tension leg platforms (TLPs), used by the petroleum and natural gas industries to support drilling, production, storage, and/or offloading operations.

FPSs described in this RP are governed by local regulatory requirements and recognized classification society (RCS) rules (if classed). No specific regulatory compliance or RCS requirements are restated in this RP. The requirements of this RP do not apply to mobile offshore drilling units (MODUs) or to mobile offshore units (MOUs) used in support of construction operations. For integrity management (IM) considerations, these units are typically governed by RCS rules, and include, among others:

— floating systems intended primarily to perform drilling and/or well intervention operations even when used for extended well test operations;

— floating systems used for offshore construction operations (e.g. crane barges or pipelay barges), for temporary or permanent offshore living quarters, or for transport of equipment or products (e.g. transportation barges, cargo barges); for these, see appropriate RPs.

This RP does not address moorings or risers; these are addressed separately by API 2MIM and API 2RIM, respectively. Dynamic positioning is not covered in this RP.

The following types of floating systems are explicitly covered by this RP:

— ship-shaped floating systems and barges (monohull or otherwise);

— semisubmersibles;

— spars;

— tension leg platforms (TLPs), including tendon systems.

The following types of floating system components are included within the context of this RP:

— hull structure, including above water, below water, and internal (i.e. hull compartments) structure and corrosion protection systems (e.g., coatings, cathodic potential, etc.);

— structural systems, such as turrets, topsides structure, helidecks, flares, cranes, and process decks, and their interfaces with the hull structure;

— mooring system support structure on the hull (e.g. foundations for chain jacks, fairleads, chain stoppers, etc.)

— tendon systems, including foundations;

— marine systems, such as ballast, bilge, venting, soundings, firefighting systems, cargo systems, emergency power, propulsion, steering, sensors, alarms, and controls (vessels in transit are not included);

— permanent means of access and egress, including walkways, grating, handrails;

— structural interfaces between hull structure and riser system;

— appurtenances;

— life safety appliances.

This RP is directly applicable to oil and gas producing floating systems operating at ambient temperature, including floating liquefied natural gas (FLNG) plants, except for the aspects related to handling and storage of cryogenic liquids.

The FSIM process provided in this RP is applicable to floating systems installed at any location worldwide. However, the referenced metocean criteria has regional limitations.
