LS2C Meeting

2. LS2C meeting 30-Jun-2017 SPS Fire Safety Project
SPS-FIRE Safety Project launched in Sep-2016 after the SPS Fire Safety Study Jan-2015 to Jul-2016
LS2C meeting Jun SPS Fire Safety Project

3. Recap of the current situation
The SPS fire safety equipment and standards date from the 1970s. Therefore consolidation and improvement is recommended.
The fire load, principally cable insulation, is deemed capable of fuelling fires in the order of tens of Megawatts of heat release rate in certain areas.
The SPS has no fire compartments in the tunnel to impede the propagation of fire and potentially activated smoke.
The evacuation system is not currently capable of evacuating the tunnel remotely, neither evacuating large tunnel areas.
Fire-fighting possibilities are currently extremely limited

4. Four Project Work Packages
WP1: (leader: Richard Morton)
Comprehensive active and passive fire compartment scheme with ventilation isolation
WP2: (leader: Michael Dole)
Automatic fire detection and protection system
WP3: (Leader: Willy Van Den Broucke)
Significantly enhanced manual fire fighting means with dry risers and CAFS (Compresssed Air Foam System) trailers
WP4: (Leader: Miriam Munoz Codoceo/Anna Suwalska)
Modern water based automatic Fire Extinguishing system in PA and TA/LSS

7. LS2C meeting 30-Jun-2017 SPS Fire Safety Project
WP1 – Fire Compartments
The fire compartments concern the SPS and transfer line connections only.
Fire partitions are required in the vicinity of the underground area of the access shaft and at the midpoint of each arc.
Some 50 doors/frames to be installed of 5 different location types
SPS Point 7 is not included.

R. Morton

8. WP1 – Fire Compartments - Planning
Currently confirming commitment and resources for the development of the basic cross sections.
Detailed planning for LS2 has started but requires complex interfaces with all other activities, first detailed draft due by end 2017.

R. Morton

9. WP1 – Outstanding Issues
Timescale for the scan processing and cross sections
Schedule for the cross sections to be confirmed
Additional resources may be needed for general arrangement drawings and as built drawings
Some areas will need additional scans/on site measurements – technical stops and YETS
Fire test
Very useful but not essential, go-no-go decision to be made
Cost was not calculated nor foreseen
Organizational risk
Planning and coordination of the works day to day
On site supervision - how many and who?
Quality control – HSE?
Reception and maintenance – Doors (EN?), Partition (SMB?), overall (HSE?)
Future coordination of works (post LS2) for cable pulling pipework etc – Responsibility for reinstatement of the partition?
Technical specification
Requires input from the EN maintenance team for the specification and in the reception of the works as well as EN-EL, EN-CV and FB
Review of cost and schedule of work package needed on the basis of the current base line

Ensure adequate resource available for integration
Define missing doors (4 number)
Verify budget allocation
Space reservation request
ECR to be done

12. WP2 – Fire Safety Systems - Status
SPS CSAP
Presentation held the 16th March (EDMS V1), well received
For safety reasons: the existing system shall be kept operational until the commissioning of the new one -> Strong integration constraints
Integration
Studies started
Visits performed in underground areas the 31st of May
Planning: requirements presented the 7th June at the LS2 SPS planning coordination meeting
R2E
First campaign on going
Second campaign to be performed by the beginning of 2018
WP2 resources: detailed workload updated (under-estimated before the start of the project), under discussion for repartition

14. WP3 // EN/CV activities in the project
EN/CV has several works related to other work packages
The main work is the installation of the Dry Risers (WP3)
X The main points updates and changes.
LS2C meeting Jun SPS Fire Safety Project
W. Van Den Broucke

15. WP3.1: Fire compartment, Fire Dampers
Control of dampers with WP1. EN/CV BE/ICS scope limits are defined.
Remaining questions on access and intervention to install the fire dampers to be clarified in detailed design.
Latest decisions:
TT61 TT70 BA7 out of scope.
Work during beam BA4 BA6. BA1 to confirm.
Work during stop BA2 BA3 BA5 TT20. TT10 remain a problem for RP issue.

16. LS2C meeting 30-Jun-2017 SPS Fire Safety Project
WP3.5: Dry Risers
12 bar max at the end, pressure reducer possible but position to confirm with fire brigade.
Double connection on surface confirmed. One outside for fire brigade, one inside directly on SPS loop in DN100
Presence, number and localization of valves on dry risers required and validated by fire brigade.
General integration layout to be done then update estimate.
Scheduling works with co-activities of other projects difficult.

17. LS2C meeting 30-Jun-2017 SPS Fire Safety Project
WP3.7 Sprinkler Supply
Latest decisions:
SPS loop confirmed as safe and sufficient water supply.
Execution Flow and pressure requirement to be calculated l/min for preliminary design : Connection replaced with DN200.
Every BA has its specific solution defined. BA3 still to be defined.
BA7 not included.
Pending issues:
Fire water evacuation and treatment (containers?)
Existing sprinkler remaining while installing new ones?

18. LS2C meeting 30-Jun-2017 SPS Fire Safety Project
WP3.x : Other CV works
WP 3.2 Air balancing. Visit done with SMB. Holes to fill identified.
WP 3.3 Cold air extraction. ECX4 dismantled, ECX5 consolidate to standards.
WP 3.4 Shaft end ventilation. New fan and cubicle down in tunnel for every BA.
WP 3.6 : Control
WP2 command Fire dampers directly and will take care of cabling.
WP3 CV will stop fan and command fire damper re-arming actuator
Only one sextant stops at the same time.
Cold smoke extraction independent of fire detection.
WP 3.7 Sump pump: Standardization of control ongoing in EN/CV.

19. CV related works to fire safety project
Toilets removal
Confirmed?
Sump pump issue: Toilet sump pump is used for lift shaft drainage.
Pump removal
Requires welding and scaffolding close to elevator
Transport and intervention scheduling issue to clarify.

23. LS2C meeting 30-Jun-2017 SPS Fire Safety Project
WP4 – Works
Location (per SPS point):
BA surface (next to the current sprinkler station)
SPS Shaft
TA Gallery, TA Passage, TA Storage Area (behind the lift)
LSS+, LSS-, Intersection
Duration (per SPS point)
weeks of installation
2 weeks for commissioning
2 - 4 weeks for dismantling of the old system (Shafts)
Start of works: Week 04, 2019
Scheduled End: Week 30/2020
Impact on other works:
Heavy piping works (welding, lowering down pipes) – the access through the shaft stairs might be limited through a period of time.
Limited space for other works
Shafts - no scaffolding but the access through the shaft stairs might be limited
TA Passage, TA Storage Area, LSS, Intersection: Scaffolding (6.0 x 1.5 x 3.0 m)
TA Gallery – access might be difficult
Other services (Plan. Activity 11195)
Power, Cabling from LSS, TA to BA surface (3 weeks before he installation end)
Drainage (SMB)
HSE-FB, HSE-SEE for Commissioning

26. LS2C meeting 30-Jun-2017 SPS Fire Safety Project
WP4 – Main Constraints
Integration: installation of the new system shall be done prior to dismantling of a legacy system but little physical space is available (the most critical problem is in BAs).
LS2 schedule is tight, leaves little margin for delays – if SPS7 is added to the scope the parallel installations in two SPS points at the same time are inevitable (= 2 contractor teams).

Closing remarks
Other SPS areas have the same fire safety issues
SPS-FIRE Safety Project Scope defined in the mandate, limited to the SPS ring, its 6 access shafts, TT10, TT20
North Area : will be upgraded during LS3
SPS Point 7
Originally excluded from the scope due to the risk analysis to perform, clearly more complicated that for the other points
Arguments by BE-ICS-AS to include the work in the contracts, execute during LS2
All WPs would be involved, not discussed yet, meeting scheduled on 3rd July
Issues to address: funding, risk analysis, implications for all WPs, work volume, manpower, supervision,…
Full Project Review foreseen in Autumn 2017
