Ch. Delamare GS-ASE

Persons in LHC – Sept. 2014 – March 2015

13

Access Systems – Special SMACC

Ch. Delamare GS-ASE

• «James Bond» suitcase

• Specific development

• Used in some LHC points

• Easier access of the SMACC train

Our opinion: useful system but not essential

14

Access Systems – Availability/flexibility

• Availability

• Very few incidents with the Access Systems

• MAD difficulties => remote operation by CSA

• Systems heavily solicited

• More maintenance

• Always difficult to find slots for maintenance

• “Swap”/juggling between the access points

• Typical use case: incident with lifts

• Flexibility well appreciated by EN-MEF

• Manual procedure for the LS1

Ch. Delamare GS-ASE

Access Systems – Lessons learnt

• Two different contexts

• Large Project (owner)

• E.g. PS Access, LHC Access LS1 evolutions

• “Small” project workpackage

• E.g. SUSI Access Control (or Fire detection works)

• plan.cern.ch was essential

• Permitted to identify tens of coming requests

• Should come asap for LS2

• Identify and analyze proposed evolutions asap (ECR)

• Point 7 Collimation: September 2012

• Preparatory phase organized by EN-MEF well appreciated

• Integration (3D) laser scans, studies and conflict detections to pursue and reinforce

• Early detection of conflicts between key projects (and “big” items)

• E.g. PS Access & PS Cooling and Ventilation

• Develop and simplify publication and approval of 3D views

• Keep the notion of “LS1 mode” (Access Safety System “in reduced mode”)

• To be planned with BE DSO

16

Access Systems – Lessons learnt

• Access conditions & Safety training

• A lot of newcomers – how to practice ? Safety Training Center ?

• Safety trainings (&DBs) must be in place much before the start of the LS

• CSA (guards) involvement

Ch. Delamare GS-ASE

GS-IS LS2 forecasts• Forecasts are needed for almost all GI-IS areas

• Budgets, service contracts

• Inform on quantity and quality change versus LS1

• E.g through plan.cern.ch enhance activity details with data such as

• Required storage space

• Material needs

• Cleaning request

• Generated waste

• CERN Stores standard items

• Anticipate project needs to identify the best suppliers, prepare supply contracts, stock only the necessary level of material (no dead stock), respond at the right time to material demands.

• Infrastructure: New building for radioactive storage

• On-going process. Can take up to 3 years

• Please answer to the corresponding surveys (+regular updates)

Ch. Delamare GS-ASE

LS1 – dedicated organization

37Ch. Delamare GS-ASE

38

Civil Engineering – Lessons learnt

• Allow sufficient time for preparation

• Many things GS-SE does are needed well before the beginning of the shutdown.

• Additional resources need to be on board well in anticipation (1 year!).

• Strategy of support contracts needs to be finalized NOW.

• Note that Civil Engineering large works require ~2-3 years from the decision to the realization (contract for design, design, building permits, contracts for works, works)

• Huge list already collected (e.g. Chamonix)

• Communicate at all level (internal/external to the group)

• Management of priorities (machine/tertiary)

• Quick decisions are needed to shift personnel from the standard services (e.g. leaking roof) to tunnel services (e.g. equipment supports)

• Time consuming participation to coordination meetings.Ch. Delamare GS-ASE
