In December 2021, we carried out Horizontal Member repair services for Larsen & Toubro Hydrocarbon Engineering Limited using Nautec’s proprietary NaX® Q140-E UHPC grout.

Scope of Work

  • Engineering services
  • Provision of manpower
  • Equipment and consumables for the repair and rectification of damaged HM Jacket horizontal bracing for Heera Re-Development Phase III Project


  • Analysis of damage
  • Engineering and design of clamps
  • Grout supply and grouting services
  • QC checks
  • Close out report

Challenges & Solutions

  • The Member was broken and bent upward due to pulling impact
  • The affected member was replaced with a new member using grouted clamp

Project Highlights

  • This was the first time a member was replaced by hinged grouted clamp technology at (-30.00) meter water depth, in Indian waters.

Project Performance

  • All deliverables were achieved with high quality and customer acceptance.

Client Benefits

  • Grouted clamp technology is one of the best methods available for under water strengthening; it takes less diving and vessel time compared to other traditional repair solutions, which in effect significantly lowers the repair cost.
