AL KHAZNAH C O M P L E T I O N R E P O R T  

G E N E R A L I N F O R M A T I O N :  

Fire Security’s crew mobilized on Saturday 31st October 2015, to Singapore, and entered onboard LNG Al Khaznah on Sunday 1st November 2015. The Supervisor in charge was Mr. Paul Filby. The crew was demobilized from LNG Al Khaznah on 22nd November, 2015 at Singapore anchorage.    

Following areas were worked in:  - Main Cable Trays along-ship on top of 5 Domes  - Cables on Dome 1  - Cables on Dome 2  - Cables on Dome 3  - Cables on Dome 4  - Cables on Dome 5  - Cables on fore mast  - Cables in Manifold area  - Compressor house cables    Notes:  Chaff damaged cables at expansion joint locations were lifted, repaired and had chaff protection installed. Chaff protection was a combination of rubber sheeting and Teflon sheeting attached to the cable tray ladders. Previous chaff protection in the form of Teflon sheeting attached to the cables was removed.

Chaff Protection of Cables at Expansion Joints on Main Cable Tray

 Previously  installed  Chaff  protection  had  mostly  protected  the  cables  but  had  allowed  water  to  collect  next  to  the  

cables.

Product comments:    The FS 5 coating is tested to provide fire resistance in accordance with a hydrocarbon fire curve of 1100 degree C for one hour in accordance with the IEC 60331 regulation.  

Further, the FS 5 coating is approved to repair cables outer sheath and tested UV and Ozone resistant. The dielectric strength of FS 5 is 8,5kv per mm thickness and will provide added safety to the cables.    Cables are an especially weak point when it comes to fire, since there are significant amounts of cables that generally are routed throughout the vessel. Cable insulation will catch fire very quickly and even a small fire can rapidly propagate throughout the vessel using cables as a pathway. Coating cables with FS 5 prevents this.    Our coatings have been approved to protect cables with the intention to ensure that signals pass through the cables when it is needed the most, and to allow you to reuse the existing cables if the fire is extinguished within a reasonable time. In this case you do not need to replace any cables as a result of the incident.  The coating will also upgrade the cables insulation value as well as increase the life expectancy of the cables outer sheath.    Please note that our FS 5 coating is resistant to mud, oil and chemicals. The FS 5 coating is also approved to repair and restore outer sheath of damaged cables.
