Description: Preservation failure of storage and handling Material
Main Contractor ENPPI and Sub-Contractors Petrojet failure to maintain proper material preservation at Brown Field and
Green Field Laydown Area of STG Project at SHEDGUM Gas Plant.
Root Cause:
Lack of Communication and provision of required resources, in addition to supervision discrepancies in maintaining the
material with proper demarcation and implementing the requirements of preservation procedures.
Root Cause Analysis:
Meeting arranged with all parties including Project Management, Warehouse, Sub-Contractors and Site Quality Team in order
to discuss the preservation issue:
 Lack of provision of required resources (Space constraint, designated manpower, Protective materials) to ensure that
warehouse can be properly laid out to accommodate all the material as per the requirements of preservation procedures.
Sufficient manpower is not provided to comply with the preservation requirements even after providing required awareness
regarding handling storage and preservation. The issues highlighted through weekly preservation walkthrough were also not
getting proper attention due to lack of resources in addition to the improper maintaining of material with suitable
demarcation (Under inspection, released for construction, quarantined material and storage as per discipline) resulted
misuse of storage area. Additional area provided for storage was also not utilized properly by providing designated areas.
 Shortage of Contractors QC personnel specially the piping QC Inspector resulted lack of attention for Receiving Inspection
of valves and preservation at Contractors location in addition to Sub-Contractor negligence of the preservation procedures
requirements and failed in maintaining piping and tested Valves preservation.
 So, additional precautions became evident to ensure proper implantation of handling and preservation requirements and to
ensure compliance to COMPANY requirements, necessary actions were concluded as follows:
- Investigation and unveiling of root causes.
- Evaluating the current condition and identifying the gaps.
- Assignment of adequate resources, including personnel and protective materials
- Assignment of responsibility regarding proper implementation of preservation and handling requirements
