Client: Confidential

Date of Started: 10/25/2019

Location: Marjan Field, Arabian Gulf,Saudi Arabia; water depth of 49.1 m.

Topside Weight: 5180MT

SOW: Based on the provided structural drawings, design basis, soil report, metocean data, WCR, and SACS models, OTL performed following optimization design and analyses:

  • Optimized the jacket structure and ensure the weight of the jacket with temporaries of lifting and rigging being less than 1700 MT

  • Optimized the topside structure and foundation piles based on iterated analysis results.

  • The optimization includes following analysis:

    o   Inplace strength analysis with DAFs

    o   Jacket and topside loadout analysis

    o   Jacket and topside transportation analysis

    o   Jacket lifting analysis

    o   Jacket on-bottom stability analysis and mudmat design and analysis

    o   Foundation pile drivability analysis

    o   Floatover marine analysis, and structural analysis for topside and jacket under critical mating loads

    o   Topside loadout analysis

    o   Topside transportation analysis
