Project Information

Synergy Engineering B.V. was engaged by Boskalis/Smit Salvage to design grillage and seafastening (G&SF) systems for the transport of jackup legs from Trinidad to Rotterdam. This project required innovative solutions for unique challenges and a rapid turnaround.

Design and Standard Compliance: Our engineering design complied with DNVGL ST-N001 guideline. The focus was on accommodating the unusual shape of the spud can and working within the constraints of limited material availability on the island.

Key Challenges:

  • Time Constraints: The project demanded a swift design process due to urgent timeframes.
  • Unique Design Requirements: The atypical spud can shape necessitated a bespoke design approach.
  • Material Limitations: The project was further challenged by the restricted selection of materials available locally.

Scope Of Work

Tasked with both conceptual and detailed design of the G&SF, our deliverables included a design report, 3D models, FEA models, design drawings and HLV strength check under transport load. Additionally, our team supervised the project on-site in Trinidad to ensure assembly was carried out as planned.

Finite Element Analysis (FEA) in Ansys

The concept was initially developed through hand calculations and then refined and verified through detailed FEA in Ansys. We considered all relevant load cases as per DNV guidelines, which were based on motion analysis.

3D Modeling and 2D drafting

Utilizing Ansys SpaceClaim and Autodesk Inventor, we developed precise 3D designs, streamlining our workflow toward the final 2D design drawings completed in Autodesk AutoCAD.

Project Engineering and offshore support

Our presence in Trinidad was critical for supervising the construction of the G&SF. We provided on-the-ground support and advice on necessary changes or adjustments, ensuring the project's success.
