LIGHTING DESIGN PHILOSOPHY FOR COMP3 PROJECT

1

INTRODUCTION

The North Field is the world’s largest natural gas field and accounts for nearly all the State of Qatar’s gas production. The principal objective of the NFPS projects is to sustain plateau from existing QatarEnergy LNG Operation – S1, S2, S3, N1 and N2, production areas by implementing an integrated and optimum investment program consisting of subsurface development, pressure drop reduction steps and compression.

NFPS projects comprise 3 main investment programs:

1. Investment #1: Drilling and Associated Facilities [WHP12S/ WHP13S/ WHP14S/

WHP12N/ WHP13N]

2. Investment #2: Trunk line Looping and Intra-field pipeline looping [32” PL1LN, 32”

PL1LS, 38”PL610LS]

3. Investment #3: Compression Complexes and associated facilities [Phase 1 CP6S & CP7S; Phase 2: CP8S & CP4N; Phase 3: CP4S & CP6N Phase 4: CP1S & CP1N]

Drilling and Looping, Investments #1 and #2, projects are in execution phase and are being executed as I1P1, EPCOL Projects except for WHP13N, which will be part of NFPS Compression Projects execution which compromises total up to 9 COMPs.

1.1 Project Objective

The objective of this Project includes:

• Achieve standards of global excellence in Safety, Health, Environment, Security and

Quality performance.

• Sustain the Qatarenergy LNG North Field Production Plateau by installing new RPs and one WHPs to support new Compression Complex facilities CP6S & CP7S and pre-installed facilities for future Compression Complex facilities including but not limited to CP4N & CP8S tie-in with integration to the existing facilities under Investment #3 program.

• Facility development shall be safe, high quality, reliable, maintainable, accessible,

operable, and efficient throughout their required life.

1.2 Project Scope

The Project Scope includes detailed engineering, procurement, construction, brownfield modifications, transportation & installation, hook-up and commissioning, tie-in to EXISTING PROPERTY and provide support for start-up activities of the following facilities and provisions for future development. The WORK shall be following the specified regulations, codes, specifications and standards, achieves the specified performance, and is safe and fit purpose in all respects.

LIGHTING DESIGN PHILOSOPHY FOR COMP3 PROJECT

7.1 General Design Concept

Lighting shall be installed in all areas of the facilities to ensure that there is an adequate level of illumination for operators / maintenance personnel to safely access all areas. Luminaires shall be installed to facilitate easy maintenance and re-lamping. Refer to “HFE Workplace Design Specification”[200-20-PI-DEC-00020] Suitable illumination shall be provided at facilities to facilitate normal operation and maintenance activities and at the same time ensure safety of the operating personnel. General lighting on the new facilities shall be categorized into the following:

• Normal lighting • Emergency and Escape lighting

The emergency and escape lighting to be located such as to illuminate the escape routes, ladders and walkways to allow safe movement of personnel to the muster points, lifeboats, etc.

Emergency and escape lighting shall be provided with self-contained batteries with autonomy of 90 minutes. The self-contained units shall be equipped with test provision and have an automatic switching device to light the unit when the normal lighting supply fails.

Lighting for outdoor operating areas that are not continuously attended shall be controlled via photocell and auto-remote-manual on/off selector switch and shall also be possible to ON/OFF from remote DCS.

The location and mounting of luminaries shall take account of efficient illumination, accessibility of luminaries and convenience of servicing. Luminaries shall not be mounted above machinery having exposed moving parts. Adjacent light fittings shall, as far as practicable, be on separate circuits. Lighting circuits shall also be arranged to prevent stroboscopic effects, so minimum two (2) circuits of lighting shall be provided at each area.

Sufficient power and convenient socket outlets shall be provided to enable maintenance to be carried out. Socket outlet circuits shall be protected with earth leakage protection in the distribution board or MCC.

Power outlets installed in hazardous areas shall be fitted with padlocking facilities. Outdoor including process area, the socket outlets shall be located approximately 1.5m above deck level measured to center of socket outlet. Sockets outlets earth pin shall be connected to earth via dedicated earth wire. Circuits connected to convenience socket outlets shall be provided with RCCB at distribution board. Plugs shall not be interchangeable with sockets of a different voltage or current rating, nor shall it be possible to insert an industrial type of plug into a Zone 1 classified outlet. Unless specified otherwise, all the outdoor welding and small power socket outlets, shall be designed for Zone-1, Gas group IIB and T3 temperature requirement.

7.2 Other Design Requirement

Lighting, sockets and junction boxes shall be provided in accordance with IEC 61892. Compliance to API RP14F is acceptable subject to COMPANY approval.

All the lighting system and Convenience sockets shall be operated at 240V / 230V AC, 1Ph+N+E, 50Hz.

3. Welding sockets (63A) shall be operated at 415V / 400V AC, 3Ph+E, 50Hz.

All lighting fixtures shall be LED (Light Emitting Diode) type.

Each outdoor lighting fixture shall be connected with sub junction box.

LIGHTING DESIGN PHILOSOPHY FOR COMP3 PROJECT

All equipment shall be designed, tested and marked in compliance with project requirements according to latest international codes and Standards.

Fixture location shall allow safe and convenient re-lamping and cleaning. In no case shall lighting fixtures be located directly over electrical equipment having exposed energized parts or equipment having exposed moving parts.

Floodlights shall be mounted and aimed in such a way that they do not impair the vision of persons approaching or leaving the illuminated area. Peripheral lights shall be installed in such that the re-lamping activity shall not become overboard job.

Light switches are provided in such a way that, these switches shall be located so that personnel can proceed from outdoor to indoor and from room to room in the unlighted building, lighting their way ahead by switches located within arm’s reach of the last lighted room or outdoors.

10. Emergency lighting shall be provided for the following equipment and areas:

Instrument and operating consoles and panels in process and utility control rooms • • Switchgear control, relaying, metering, lighting panel, and alarm panels in the following

areas: −

Radial substations with intertripping (transfer tripping) connections to their source substation feeder breakers

Instrument and equipment rooms All substations to the extent necessary for personnel to safely exit the building Equipment access ways, emergency escape routes, evacuation routes, stairs,

Crane control panel and access ways / ladders Key operational areas such as, platform supervisor or co-ordinator’s offices, radio/telecom room(s), Access to helideck area Life raft embarkation areas

11. Emergency lighting illumination levels shall have a minimum average value on the “seeing

task” (surface requiring emergency lighting) of 22 lux (2 foot-candles).

12. Plugs shall not be interchangeable with sockets of a different voltage or current rating, nor

shall it be possible to insert an industrial type of plug into a Zone 1 classified outlet.
