The main objectives of providing active fire protection systems for the platforms are to:

• Contain / reduce the effects of smoke and radiation

• Provide cooling (when firewater is available)

• Extinguish moderate fire as appropriate

For safety of personnel, active fire protection systems provided for offshore platforms are not designed to fight / extinguish escalated fire. During such MAE, personnel are required to muster in the LTR and evacuate / abandon the platforms.

Active fire protection systems and equipment will be provided for the platforms that have a significant hydrocarbon inventory and/or that are regularly manned.

Active fire protection systems for the platforms comprise the following:

• Firewater system

For the wellhead platform, which is not normally manned, a dry pipe deluge system will be provided to give protection (to provide cooling water spray) to the wellheads and the manifolds. This dry pipe system will be connected to the jack-up rigs firewater system when the rig is on station. Operation of the system will be done manually or automatically from the jack-up rig. Also, this dry pipe system will be

provided with a connection (at the boat landing) for firewater supply from the boat. No manually operated firewater appliances such as hose-reels, hydrants or monitors will be provided.

• Gaseous system

Gaseous system provided for the platforms consists of total Flooding system for the LTR.

• Twin Agent skid

Twin-Agent skid comprising foam (AFFF) and dry chemical will be provided for the Helideck.

• Wheeled and Portable fire extinguishers

Wheeled extinguisher system will be provided for CO2 (22 kg) and dry chemical powder (45 kg). Portable extinguisher system will be provided for CO2 (5 kg) and dry chemical powder (12 kg).

Appendix II of this document provides the quantity and locations of the wheeled and portable fire extinguishers on the platforms.

9.2.1 FIRE ZONES

A fire zone is defined as an area where fire shall be contained by means of fire walls, decks, bulk heads or open side to the sea. Fire zoning allows a clear indication of the location of an incident to be received in the control room so that suitable emergency response can be planned.

The platforms will be subdivided into fire zones as follows: Fire Zones WHP1 / WHP2 and WHP3

Areas

Fire Extinguishing Capabilities

1 Helideck / Main Deck As per Appendix II

2 Hazardous (Process) Areas on Mezzanine, Cellar Decks and boat landing

Deluge system and as per Appendix II

3 Non-Hazardous areas (LTR, battery room, WHSC, transformer)

As per Appendix II

Each fire zone shall be suitably equipped (where appropriate) with means for fire and gas detection and fire fighting.

Calculation of firewater demand / deluge quantities will be based on the Fire Zones above and will be provided in the Firewater Demand Report.

Means of fire fighting will be designed and the capacities will be calculated based on the defined designated fire zones and in accordance with the relevant NFPA codes.

9.2.2 CONTROL OF FIRE FIGHTING EQUIPMENT Control of the fixed fire fighting systems will be as follow:

Fire Fighting Systems Locations Control

Twin Agent system (hose reel) Helideck Local & manual upon helicopter accident on the Helideck

Deluge system Mezzanine, Cellar,

Closed Drain decks

Local & manual on the jack-up rig (upon confirmed fire alarm from F&G system) and Manual supply of firewater from a standby supply boat (upon confirmed fire alarm from F&G system)

Flooding system LTR (Mezzanine

Deck)

Automatic and manual (local) activation upon confirmed fire

Automatic and remote manual control will be via the Fire and Gas executive system.

9.2.3 FIREWATER (DELUGE) SYSTEMS

As far as practicable, the fire main (dry pipe main headers) routing will be such that maximum use is made of structural shielding in order to minimize the risk of damage by impact, blast and resulting projectiles.

Deluge will be provided where necessary for cooling purposes of high pressure process vessels, hydrocarbon pumps, pipe-work / manifolds and to provide general area protection for cellar and mezzanine decks. Water will be applied to these areas at a rate of 10.2 l/m2/min in accordance with NFPA 15.

Deluge will be provided in well-bay areas at a rate of 400 l/min per well in accordance with industry practice and ISO 13702 recommendations.

Deluge valve is located on the jack-up rig. Release of deluge valve will be by manual activation upon fire alarm raised by F&G system.

Main Supply of fire water to deluge areas will be from the fire ring main via isolation valves, lockable in open position. After drilling period, supply of fire water to deluge areas will be from the standby supply boat (If any).

9.2.4 CARBON DIOXIDE (CO2) FLOODING SYSTEM

Carbon dioxide flooding system will be provided for the unmanned LTR. Carbon dioxide systems will be designed for deep seated fires in electrical and instrument equipment enclosures.

The system will be automatically / manually activated upon confirmed fire by the F&G system. Manual local discharge will be possible by direct manual actuation of the controls in the storage cabinets. A pre- discharge alarm will be provided, 30 seconds before discharge commences.

Protected areas will be arranged and designed such that all ventilation is stopped; fire dampers are closed and relevant equipment shutdown automatically prior to discharge of CO2.

Additionally, interlocks shall be provided between entrance doors to LTR and CO2 discharge. Before personnel can enter a CO2 protected room, CO2 discharge must be mechanically and electrically isolated. The CO2 system status (including the discharge inhibit state) shall be displayed in the relevant Main Control Room (MCR) at onshore facilities.

Spare capacity (100%) shall be installed and fully hooked up in each carbon dioxide skid cabinet.

9.2.5 TWIN-AGENT SKID

Twin-Agent system / skid combine foam (AFFF agents) and dry chemical powder. The self-contained system shall utilize nitrogen to charge and expel a combination of dry chemical in one vessel (to extinguish the fire) and the premix foam solution in the other (to blanket the flame-free surface) through the twin hose assembly.

The application rate of the twin agent is 4.1 liters per square meter per minute as minimum. Total application of 2 minutes is required as per NFPA 481.

One skid will be required to be located at each excess to the Helideck.

9.2.6 WHEELED AND PORTABLE FIRE FIGHTING EQUIPMENT

Portable and wheeled fire extinguishers shall be provided at strategic locations around the installation. The following types of portable fire extinguishers shall be used as appropriate to the type of risk:

• For areas where there are ordinary combustibles, such as wood, cloth, paper, plastic, etc. extinguishers shall be suitable for Class A Fires. These shall be dry chemical.

• For areas where there are flammable liquids, oils, greases, paints etc extinguishers shall be suitable for Class B fires. These can be dry chemical or carbon dioxide.

• For areas where there is energized electrical equipment, extinguishers shall be suitable for Class C fires. These shall be dry chemical or, preferably, carbon dioxide.

Wheeled and portable fire extinguishers will be located as follows:

• Helideck – 22 kg wheeled CO2

• Main Deck (near chemical tote tank area) – 12 kg dry powder.

• Process and utility areas - 12kg dry chemical, 45 kg wheeled dry chemical, 5 kg CO2

• LTR – 5 kg CO2 and 12 kg dry powder.

• Transformer, wellhead safety cabinet (WHSC), battery room – 5 kg CO2

Appendix II of this document provides minimum quantities of the wheeled and portable fire extinguishers.

CO2 extinguishers located at the Helideck access platforms shall be provided with suitable applicators to enable the contents of the extinguisher to be directed into the helicopter engine.
