INTERFACE: INTERFACE: it is proposed to have one QA/RA responsible for each WP and per country. He refers directly to the WP7

Steering Committee:Steering Committee:

WP7 Meetings: WP7 Meetings: twice per year



WP 7 activities: Starting Point

1.) Deep study of the overall Project to identify the WPs’ links

2.) RA & QA activities are carried out in the framework of the KM3NeT Project:

to increase the knowledge about the submarine technologies and neutrinos detection (lesson learned from ANTARES, NEMO & NESTOR Projects)

(meetings were done in Paris, Marseille, Aberdeen and Italy) to prove the reliability of the RA & QA methodology

(from the PCC meeting of October 2006, application to the on going project)

to identify the weakest points



WP 7 activities performed: QA

Analysis of the ANTARES project- QA should start with the design study to be ready for the

production

Analysis of the NEMO project- Application of the QA and RA methodology developed to:

• Define and diffuseDefine and diffuse the “Quality Culture” overall the WPs• Obtained a common standardisation by an integrated strategy

among the different WPs.

Just to recall

QUALITY = Requirements definition

QUALITY ASSURANCE = To plan the actions to achieve the requirements defined

QUALITY CONTROL = Measurement of the results achieved with reference to the requirements defined




WP7: RA Objectives & Road Map for KM3NeT

Road Map

Risk Analysis involves three major stages:

Collect project/processes data;

Assessment of the undesired consequences of a potential set of actions;

Assessment of the probability that these consequences may obtain.

Objectives

1) Define the mission of the neutrino telescope in quantifiable terms;

2) Assess specific scenarios (sequences of events) that can lead to the inability of the system to perform its mission;

3) Assess the probability of each and every scenario.



WP7: Risk Analysis Actual ActivitiesFMECA ANALYSIS Qualitative Example (related to PCC Rome Meeting Request)

Analyzed Component : Optical Module

Hypothesis:

1. OM into its environmental conditions (working life);

2. Components cant’be repair (MTBF=MTTF=1/λ)

3. Criticality Analysis is only qualitative and based on MIL-STD 1629 A normative ;

4. Objects Information are based on the available licterature (there are not yet available risk data).

Goals:

Give remarks about possible test benchs development to simulate the Failure Causes put in evidence;

Focus on Risk parameters needed.



WP7: Risk Analysis Actual ActivitiesFMECA ANALYSIS Steps

Explode the Objects under analysis in all its parts (through a filled Questionnaires)

Build up FMECA TABLE by using modified MIL-STD 1629 A worksheet

Put in evidence the relevant functions by logical flow diagram

Brainstorming on potential failure modes, causes and effects

Allocate severity level and probability of occurrence using MIL-STD-1629 A reference tables

Build Up “Criticality Matrix”

Give final remarks



WP7: General RA Conclusion

1. Although Qualitative, Criticality Matrix focuses on :

Possible Criticality, using color ranking from Red (unacceptable condition) to Green (acceptable without revision)

Objects ordered by criticalities

2. Although Qualitative, Criticality Matrix gives a priority to the objects tests (related to the failure causes) based on the above ranking

Example of procedure after FMECA results:

Step 1) rank Criticality level by unacceptable to acceptable

Step 2) Calculate experimental MTBF from the worst to the better condition

Step 3) Verify availability and find solution to improve, if is necessary



WP 7 results 1 of 2

The work performed outlines that for a correct application of the QA and RA, it is needed to develop in the design study:

Functional analysis Definition of the requirementes Definition of the technical specifications

It means interaction with the WPs



WP 7 results 1 of 2

The QA/RA needs to define the reliability level to be reach. It is translated in:

Tests to be performed

Relation with the suppliers, which- Tests they should perform- Certificate they should release- Level of non conformity we consider acceptable

Definition of the preproduction and production specifications

WE HAVE A DREAM:

“Let us try”KM3NET WP7 Motto




"Design Study for a Deep Sea Facility in the Mediterranean for Neutrino Astronomy and Associated Sciences”

THANK VERY MUCH FOR YOUR KIND ATTENTION



Draft CDR contribution describing the standards and the quality evaluation method for all the Design Study procedures and initial results of the FMECA RA studies (16 month)

- Deep study of the Project (July 2006)- Collection of several normative and standards (June 2006)- Selection of the suitable normative and its application (ISO)

(May 2006)- QA & RA Questionnaire (May 2006)- Development of a preliminary QA manual (July 2006)- Preliminary Standard Data-Base model (June 2006)- FMEA/FMECA standards and methodology study (July 2006)
