Summary - Conclusions

• RSWI a viable solution• increase in injection capacity• minimised impact on existing facilities• re-deployment possible?

• Robust proven technology – a new applicationRobust proven technology a new application• reliable – 100% uptime since start up one year ago• in depth qualification of “new” elements

Summary - Conclusions

• Take the opportunity of high specification• e.g. single controls system• supports economic viability• simpler, efficient interface

• Mitigating project risksMitigating project risks• key elements with a single “system provider”• additional extensive testing performed filter and SCM• comprehensive SIT, wet & dry test (Framo Subsea test

d k) d h diff ”T ti b d thdock); made a huge difference. ”Testing beyond the normal; built operational confidence”

Summary & Conclusions
