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
