Disconnect switches in general purpose enclosures should not be used offshore in classified locations; this is a departure from the NEC. Inch, size or larger conduit run entering an enclosure that contains splices, taps, or terminals.
Regulators such as U. Type PLTC appi, power-limited tray cable. Applicable gas classification group s eg. Must be installed in and explosion proof container unless the certificate states otherwise.
Mineral-insulated 14ff cable as defined by NEC Article Applicable gas classification group s.
Upstream 500 – 505 (API RP)
Zone 2- Not likely or normally confined in containers. This is to provide a higher level of protection for their hazardous area equipment and personnel as they deem necessary. They accomplish this by maintaining a permanent seal. Strict rules must be followed, system calculated to ensure energy levels 14 within tolerances and diagrams must be followed closely as wells as the current RP, Codes and Standards. Energy Limited nL Limit energy of sparks; wpi the temperature of a device replaced by Ex ic.
Nonincendive equipment is normally limited to communication and instrumentation systems.
Sealing accomplished by fusion of metal to metal or sealed through glass to metal. If Associate Apparatus is placed in the 14t area then it must have another ai of protection. Spi only intrinsically safe when employed in a properly designed intrinsically safe circuit. C — Sparking equipment in which the contacts are suitably protected other than by restricted breathing. As tested by the NFPA This document is intended to bring together in one place a brief description of basic desirable electrical practices for offshore electrical systems.
Markings on the equipment to ensure the correct location of installation are as follows; Zone Equipment.
OK Forward looking statement. All seals should be installed as close as practicable, but in no case more than 18 inches, from the enclosures to which they are attached. Must provide adequately maintained breathers and drains to prevent accumulation of moisture This document provides guidelines and recommended practice for the satisfactory design of offshore structures against fire and blast loading. This document recommends minimum requirements and guidelines for the design, installation, and maintenance of electrical systems on fixed and floating petroleum facilities located offshore.
The practitioner should in all cases seek full and proper guidance from the relevant legislation and codes aapi practice in addition to following company guidelines and procedures. Providing protection from fire, smoke, water and blast pressures.
Associated Apparatus 14ff apparatus that not all the circuits are intrinsically safe. The surrounding gas air mixture can automatically pai with out a spark being formed.
The classified areas are different and some protection concepts also differ. Zone 1 Equipment must be certified as meeting the requirements of the area this could be a number of different protection concepts not just Flame-Proof.
API RP 14F: Recommended Practice for Design and Installation of
Wpi cable as defined by NEC Article This document recommends minimum requirements and guidelines for the design apu installation of electrical systems on fixed and floating petroleum facilities located offshore. These advantages may include reduced initial capital expenditures, enhanced safety, or facilities that are more easily and more economically maintained.
Explosion proof equipment may not provide protection against the ingress of liquids or solids therefore, breathers and drains may be required. Metal-clad cable for hazardous locations as defined in UL MI cable: Published by Nickolas Allan Jenkins Modified about 1 month ago.
This recommended practice is intended to assist in development of a management program designed to promote safety and environmental protection during the performance of offshore oil and gas and sulphur operations. Grounding of electrical equipment on fixed and floating offshore petroleum facilities in a positive manner is of particular importance because personnel standing on steel decks or in contact with steel framing present a low impedance path to ground, effectively grounded For sizing equipment grounding conductors, refer to NEC Pai.
This recommended practice covers methods of installation for pressure-relief devices for equipment that has a maximum allowable working pressure MAWP of 15 psig 1.
qpi About project SlidePlayer Terms of Service. This document recommends minimum requirements and guidelines for the design and installation of new piping systems on production platforms located offshore.

If you wish to download it, please recommend it to your friends in any social system. This equipment has additional security against the possibility of excessive temperature and the equipment is assembled very carefully to ensure that arcing or sparking from part to part or connection to connection will not occur.
Why is it NOT acceptable? This ensures that apu gas or vapor located above the arcing or sparking parts or the gas or vapor located exterior apu the enclosure cannot be ignited by the electrical arcing parts within the oil.
Thus, the protection techniques for equipment to be installed in Zone 1 locations can be less demanding than the protection techniques for equipment to be installed in Division 1 locations. Medias this blog was made to help people to easily download or read PDF files.
