Technical Consultancy

Advanced Numerical Modelling & Complex Analysis

At Sea & Gao, we have developed an inhouse particle method tailored for addressing large motion and breaking waves phenomena. This method has found applications in coastal wave analysis, liquid sloshing, and green water slamming assessments.

In addition, we harness an array of diverse numerical techniques and high performance tools to address intricate challenges spanning both the naval architectural aspects of marine offshore structures and the structural mechanics aspects of large steel structures. 

Our toolkit comprises commercially available software packages commonly employed in the marine and offshore industry, as well as open-source code packages like OpenFOAM.

Some illustrative applications of these tools include:

  • FEM Analysis and Fatigue assessment
  • Structural integrity and health monitoring
  • Propeller characteristics
  • Ship hydrodynamic performance
  • Ship grounding or collision investigation
  • Liquid sloshing and wave slamming
  • Coastal wave simulation and interaction with structures
  • Vortex induced vibration for deep-water risers and pipelines
  • Cargo lashing and transportation
  • Mooring analysis

Ocean Engineering

Leveraging our advanced computational expertise, we employ mathematical and scientific methodologies to address challenges arising from tidal forces, waves, and currents affecting a wide range of coastal, offshore, and subsea structures. Whether it involves the analysis of ports, coastal zones, subsea pipelines, wind turbines, wave-energy harvesting devices, mooring buoys, Floating Production Storage and Offloading (FPSO) units, or oil platforms, our capabilities extend to provide effective solutions in diverse marine and offshore environments.

Litigation Support

Expert Witness

We conduct forensic investigations into a diverse range of structural failures, marine casualties and incidents.  We serve as expert witnesses and offer expert testimony in arbitrations and courts in many countries. Our familiarity with the specific requirements governing the use of expert evidence in various jurisdictions enhances our ability to provide valuable insights and support to our clients. A significant proportion of these cases are resolved through the leading maritime arbitration institutions, including but not limited to LMAA, SCMA and HKIAC.
