SPS-FIRE The SPS Fire Safety Project Planning Status R. Billen BE-ASR 30th June 2017 LS2C Meeting

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 30-Jun-2017 SPS Fire Safety Project

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 LS2C meeting 30-Jun-2017 SPS Fire Safety Project

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 LS2C meeting 30-Jun-2017 SPS Fire Safety Project

Project Core Team But many other people and teams are involved and solicited! LS2C meeting 30-Jun-2017 SPS Fire Safety Project

LS2C meeting 30-Jun-2017 SPS Fire Safety Project Overall Planning Main phases Taking into account tunnel accessibility LS2C meeting 30-Jun-2017 SPS Fire Safety Project

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. LS2C meeting 30-Jun-2017 SPS Fire Safety Project R. Morton

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. LS2C meeting 30-Jun-2017 SPS Fire Safety Project R. Morton

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 LS2C meeting 30-Jun-2017 SPS Fire Safety Project R. Morton

LS2C meeting 30-Jun-2017 SPS Fire Safety Project WP1 – Next Actions Agree schedule for cross sections Ensure adequate resource available for integration Define missing doors (4 number) Verify budget allocation Space reservation request ECR to be done Place order for frame and partition design Place order for Prototype for BA4 Prepare IT Organise Fire test – if decided LS2C meeting 30-Jun-2017 SPS Fire Safety Project R. Morton

WP2 – Fire Safety Systems - Status Scope : fire detection system (SDI), fire protection system (SMSI) and voice alarm system (SSS) PLAN: 3 activities created before the start of the project, merged into one for WP2: 10777, 10724, 10775 Market survey (MS-4286) Sent to 20 firms the 17th March 9 answers received 4 firms qualified Invitation to tender (IT-4286) Document sent to the Specification Committee the 7th June: verification in progress End of July: Document sent to firms 13th December: Finance Committee LS2C meeting 30-Jun-2017 SPS Fire Safety Project M. Dole

WP2 – Fire Safety Systems - Status SPS CSAP Presentation held the 16th March (EDMS-1763848V1), 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 LS2C meeting 30-Jun-2017 SPS Fire Safety Project M.

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 30-Jun-2017 SPS Fire Safety Project W. Van Den Broucke

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. LS2C meeting 30-Jun-2017 SPS Fire Safety Project W. Van Den Broucke

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. LS2C meeting 30-Jun-2017 SPS Fire Safety Project W. Van Den Broucke

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. 2200 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? LS2C meeting 30-Jun-2017 SPS Fire Safety Project W. Van Den Broucke

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. LS2C meeting 30-Jun-2017 SPS Fire Safety Project W. Van Den Broucke

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. LS2C meeting 30-Jun-2017 SPS Fire Safety Project W. Van Den Broucke

WP4 – Layout at each SPS point LS2C meeting 30-Jun-2017 SPS Fire Safety Project A. Suwalska

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) 10 - 14 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 LS2C meeting 30-Jun-2017 SPS Fire Safety Project A. Suwalska

LS2C meeting 30-Jun-2017 SPS Fire Safety Project WP4 – 2019-2020 site planning CASE1: SPS point 7 not included in the scope In line with the original SPS-FIRE Safety project planning LS2C meeting 30-Jun-2017 SPS Fire Safety Project A. Suwalska

LS2C meeting 30-Jun-2017 SPS Fire Safety Project WP4 – 2019-2020 site planning CASE2: SPS point 7 included in the scope Not foreseen in the original SPS-FIRE Safety Project planning Recent request, not discussed at project level LS2C meeting 30-Jun-2017 SPS Fire Safety Project A. Suwalska

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).
