E-784 - Subsea Integrity Management (II) - Non conformity management

5 days PL/SUBINT2
Level
Proficiency
Audience
  • Engineers and technicians whose activity is related to the operation of oil & gas subsea facilities
Purpose
  • To provide technical knowledge on oil & gas subsea facilities
Learning Objectives
  • To determine integrity characteristics
  • To evaluate consequences of failures
  • To plan repairs
Ways and means
  • Lectures carry numerous examples from ongoing projects
  • Trainers are specialized engineers currently involved in deep offshore projects

PHYSICAL/STRUCTURAL INTEGRITY ISSUES AND THEIR MAIN CONSEQUENCES
  • Stress & fatigue
  • External corrosion, internal erosion/corrosion
  • Hydrogen induced stress cracking
  • External event
  • Thermal Insulation, heat loss
  • Case studies, prevention & remediation
“FUNCTIONAL” INTEGRITY ISSUES AND THEIR MAIN CONSEQUENCES
  • Defective subsea retrievable modules
  • “Internal” leakages (passing valves, passing non-return valves…)
  • Leaks to environment
  • Electrical lines/conductors defects
  • Monitoring sensors signal loss
  • Hydraulic locks
  • Chemical lines blockages
NON CONFORMITY MANAGEMENT
  • Objective
  • Non conformity
  • Non conformity “dossiers”
  • Non-conformity register/database
MAINTENANCE & REPAIR
  • Planned events
  • Unplanned events
