PROBLEM 002 Pipe lines block due to the by-products of the salt water environment .
The problem is so bad today that operators are focusing on preventing pipes from blocking rather than on the sprinkler heads themselves !
The risks and costs of service and maintenance are high , with rope access being required on the majority of these systems .
It was missed by an operator that the RigDeluge ® CFT™ Adaptor protects the sprinkler heads and allows water to the fire . He was more concerned about the pipe blocking and the effect the RigDeluge ® CFT™ Adaptor would have on a maintenance regime than getting water to the fire on demand .
Note : Sprinkler heads that block actually cause service and maintenance regimes to be extended !
LESSONS 002
• Full system failure
• Rodding required to clean
• Contamination is environmental based
• Expensive servicing regimes required
• Fail & Fix process fails in the event of a fire !
• Maritime classification required
• Blockage testing required for system
• Poor service and maintenance contribute to blocking
• Sprinkler heads and screens fail through pipe blockages
• In line filters fail
• Bypass valves allow debris into system
• All delivery line materials suffer from marine by-product contamination
SOLUTION 002 RIGDELUGE ® DEBRIS DRAW DOWN FILTER™
We have now achieved a solution based around the full host of problems encountered - retrofit products that will enable clients to service and maintain whole systems during operation .
Where pipe lines block in an end of line position ( as shown ), introduce a RigDeluge ® Debris Draw Down Filter™ ( DDDF™ ).
While the RigDeluge ® CFT™ Adaptor allows water to the fire , the RigDeluge ® DDDF™ removes large quantities of debris from the delivery line .
The RigDeluge ® DDDF™ is the first filter in the world that does not sit in the direct flow path of the delivery fluid . All other filters have the potential to block a delivery line when they themselves become blocked ( as frequently happens on the inlet to a fire sprinkler system ) where the bypass is activated ; contaminants make their way through the system , thus contributing to its failure when tested or when activated in the event of a fire .
When the RigDeluge ® CFT™ Adaptor and RigDeluge ® DDDF™ are used in conjunction ( as shown ), the delivery lines will be kept free from debris .
( PROBLEM 003 will note the small branch down pipe solution )
The RigDeluge ® DDDF™ mitigates the requirement of rope access as it can be located at ground level . This enables predicative service and maintenance regimes to be implemented by vessel operators . It also mitigates the risks associated with working at height and over water , whilst reducing personnel on the helicopter and freeing up the bed space for other production operations to be complete .
After the initial upgrade , cleaning , service and maintenance activities will be dramatically reduced .
Note : During research and development , it was recorded that 90 % of the contaminants would be removed from the delivery line if the RigDeluge ® DDDF™ was positioned before the actual system .
COSTS 002
The initial cost reduction , as for the RigDeluge ® CFT™ Adaptor , will be for the removal of the Fail & Fix process (£ 38K on repeat ).
Cost reduction thereafter is un-quantifiable , through the mitigation of rope access and improved production .
The unit cost for the RigDeluge ® DDDF™ when purchased with the RigDeluge ® Reducing Bush™ will be £ 500- £ 1000 per individual system .
