Project overview:

  • Critical path flare scope during TAR, involving the inspection of pipe work structural steel. 
  • Removal of obsolete pipe work and steel work including a half landing structure.
  • Installation of new pipe work and steel work.
  • Removal of cladding from 12" line from underside of flare weather deck.
  • Fabric maintenance.
  • Installation of ClockSpring to other pipe work sections.

 Key Challenges:

  • Critical path scope for TAR.
  • Time constrained.
  • Requirement to work multiple work faces simultaneously.
  • Personnel physically in water (exposure to cold, buffeting from swell).
  • Project required a spread of skills in a small team.
  • Isolation of work site.
  • Availability of competent material applicators (ClockSpring)
  • Removal of half landing in same time frame.

AquaTerra's Solution:

  • Select experienced and competent team.
  • Verify competence in core skills.
  • Train all team members in support functions for complete flexibility and rotation of team at worksite.
  • New training to ensure all tasks could be completed (ClockSpring) safely and competently.
  • Use of Netting to facilitate multiple work areas.
  • Working in daylights hours.
  • Compiled a plan including lift plans to remove the half landing.


  • Project and resources were managed and closed out completely by AquaTerra personnel both on and offshore.
  • No requirement to change out personnel.
  • Ability to rotate personnel eliminated non-productive time - maximised weather windows of opportunity, increased utilisation and productivity (wrench time).
  • Built-in redundancy - multiple personnel trained and interchangeable.
  • No requirement for third party support.
  • Reduced bed space requirements.
  • Removal of half landing during the time frame saved the client the necessity of another TAR.
