Off Shore Engineering

Off-Shore engineering services include detailed structural analysis, Finite Element Analysis and Computational Fluid Dynamics. In addition, 3D scaled models can be created from CAD models in order to simulate and verify interaction between modelled components.

The types of FEA and CFD analysis methods available are as follows:

  • Structural FE Analysis - 3D Design, Explicit and Implicit, Linear and Non-Linear, including:
  • Static analysis of Steel and Composite structures
  • Buckling
  • Nonlinear
  • Linear Dynamic
  • Fatigue analysis
  • Pressure vessel Design
  • CFD - External and Internal Flow simulation, including:
  • Determination of drag coefficients and flow within pipes and ducts
  • Heat Transfer
  • Ventilation
  • Mixed Flow Simulation
  • Fluid-Surface Interface (FSI)
  • Rotating Machinery
  • Code checks (e.g. DNV, Lloyds, ABS)
  • Development of Innovative Structural Solutions

Case Studies for some recent applications of Offshore Engineering

Development of Jackets and Transition Pieces for Wind-Turbine Installations:

A series of Transition Pieces, for 6MW wind turbines, have been developed with the main aim of reducing weight and fabrication costs while allowing for a fatigue life in excess of 25 years. Of the range of different concepts investigated, a design, with an inverted conical section, that connects the turbine mast to the jacket, emerged as the most efficient and advantageous design. The concept was designed for jackets in shallow (20m) and medium (up to 60m) water depth.

Natural Frequency Extraction:

Linear dynamics analysis with the aid of FEA has been used on a variety of structures. These include Eigen value extraction for determination of natural frequency as well as Modal analysis.

Recent examples include:

  • Natural frequency and modal analysis of an Off-Shore Wind-Turbine Foundations
  • Natural Frequency determination of a furnace, at operating temperature of 2500C

Innovative Foundations Systems:

In the course of development of Wind Turbine Foundation systems, several new concepts have been developed. The principal aim had been to facilitate rapid deployment and overcome some of the current operational problems that this industry has been facing. All these concepts had been subject to extensive Finite Element Analysis.

Recent examples include:

  • A Demountable Pile Joint
  • Mono-Pile with retractable skirt piles
  • Tower Levelling system.

Computational Fluid Dynamics Simulation:

Computational Fluid Dynamics (CFD) has been used for a variety of applications.

Some recent examples include:

  • External and Internal Flow simulation,
  • Determination of drag coefficients of anode systems,
  • Mixed Flow at gas Flue outlet,
  • Flow within pipes and ducts.
