WHAT DO WE DO?
Moonpool Consultants Pte Ltd is a company based in Singapore. They provide three kind of Services: 1. Engineering
I. Basic Design II. Construction Preparation
2. Budget & Procurement 3. On-Site Supervision
Major construction projects To date, Moonpool Consultants Pte Ltd has successfully led several projects to completion: Soehanah - New built jack-up Rig 105 - Conversion of a swamp barge Yani - New built swamp Barge Maera - Re-built swamp barge Raissa - New built swamp Barge
Main Structural Analysis Tasks:
1. Global Analysis
2. Spudcan
3. Hull Analysis
4. Jacking House and Leg Well
5. Cantilever
6. Helideck
7. Crane Pedestal
Global Structural Analysis
Main Challenges for analyses:
1. To build a robust FEA model with least simplification.
2. To create accurate representative elements at connections
3. To create both Static and Environmental loads with accuracy
4. To run more realistic analysis.
5. To post process result with more understanding and control.
Typical Software used for such analysis in Industry:
For Global Analysis:
Beam Modeling Software with Hydrodynamic Load
creation capability. They also provide unity check for
the model.
For other detail Analysis:
General purpose software like Femap with NX Nastran.
Limitations of Beam Modeling Software:
1. FEA model is too simplified to fit capabilities of the
software.
2. Easy for Beam modeling very difficult and tedious for
plate modeling and can not create solid model.
3. Sometimes peak results are less reliable.
4. Engineers need to learn two software.
5. Cost of ownership high.

Result from Femap with NX Nastran
Benefits:
1. Entire structural analysis performed using Femap with NX Nastran.
2. FEA engineers spent less time in learning the software and
focused more in acquiring expertise on it.
3. Engineers could reuse models for more detailed analysis.
4. Robust FEA modeling of Femap enables relatively faster design
change verification.
5. Cost of ownership of one software is always lower.
