Design of Platform Strengthening and Repairs

Design of Platform Strengthening and Repairs

Project involved determination of the  structural integrity and fitness-for-purpose to support proposed deck extensions, gravity loads, and to design strengthening or modifications where necessary.

The scope of work involved:

  • Designing and detailing of new deck extensions for pig receiver, including IFC (Issued For Construction) drawings,                                       
  • Performing integrated topside and jacket structure assessment: API RP2A WSD and LFRD for as-is members (accounting for effects of damaged member- with and without damaged member) Review pipe supports on proposed decks,                                              
  • Performing ultimate pushover analysis of as-is (damaged member) to determine Reserved Strength Ratio (RSR),
  • Design of stressed mechanical clamp for replacement of brace to jacket leg,  
  • Performing static and fatigue Finite Element Analysis (FEA) to validate the clamp design by hand calculations,                          
  • Preparation of clamp fabrication drawings,
  • Design of strengthening scheme for connection of new brace to existing brace, 
  • Performing fatigue assessment of as-is and repaired structure using SACS         
  • Preparation of structural assessment and design reports (SACS & ABAQUS) as required.
