Cable Quality Assurance Services

Cable Quality Assurance Services

Fault-free operations require highest quality and respectively quality control during manufacturing and installation. The highest cable-specific requirements on quality measurements are set by ISO 13628-5, design and operation of Subsea Umbilical’s. Measurements are required for the following steps:

  • At Cable Manufacturer:
    - components acceptance test
    - condition control
  • At Umbilical Manufacturer:
    - post umbilical manufacture
    - condition control
    - umbilical final acceptance test (FAT)
    - condition control
  • At Loadout to Installation Vessel:
    - pre loadout test
    - post loadout test
  • Transport & Installation:
    - integrity monitoring during lay
  • Post Installation
    - condition control
  • Trenching & Rockdumping:
    - pre & post condition control
  • Pre Connection (connection is typically performed some time after installation):
    - condition control
  • Post Connection:
    - condition control
  • During Operation:
    - monitoring
    - regular condition control 

Our Cable Quality Assurance Services performed with LIRA® Technology will ensure highest quality from the first moment, as LIRA® can detect all deteriorations and their severity which might have been induced during manufacturing and installation.
All measurements data will be stored like a fingerprint for future use e.g. for introduction of condition based maintenance (CMB) based on regular assessments for even online condition monitoring.

Features

  • Best-in-class cable diagnostic system.
  • Sensitive to small degradation and defects.
  • Accurate Hot-Spots and deviations location.
  • Non-intrusive and non-destructive.
  • Applicable on multi-segment systems with different cable types.
  • Pre-study/simulation of cable data and defects.
  • LIRA® performs a power spectrum analysis of impedance phase and amplitude – an advanced detection method of abnormal conditions.
  • Fast and simple connection to test object.
  • Only one access point needed for measuring.
  • LIRA® provides possibility to zoom in on the blind zone at the near end termination. This feature enables detailed, high resolution measurements in the cable end close to the connection point.
