Offshore Marine Engineering Advanced Analysis & Simulation

Consulting & Engineering ⁄

Advanced Analysis & Simulation

AqualisBraemar LOC has access to a broad range of engineering software which our naval architects, structural and civil engineers use to analyse the most complex of problems.

We can draw on our advanced analysis and simulation expertise to support design and engineering projects for all marine structures but with a particular focus on the construction, transportation and installation phases of an offshore project. For floating and fixed structures, these services are provided for the whole lifecycle, from concept to operations, life extension and decommissioning.

We also provide independent technical support and advice to owners, salvors or insurers following a shipping casualty, during salvage or wreck removal operations or as part of subsequent casualty investigation for dispute resolution.

    Computational Fluid Dynamics

    AqualisBraemar LOC company Longitude Engineering has extensive experience covering fluid flow problems and the use of turbulence-resolving modelling approaches for various physical and application areas. Our specialists have been working across all industries with a special focus on the marine, energy and other offshore sectors. We cover:

    • Custom-developed Tools and dedicated in-house services
    • Aerodynamics
    • Hydrodynamics
    • Thermal Analysis

    Advanced Finite Element Analysis

    Longitude Engineering’s structural engineers have extensive experience with advanced finite element analysis in the marine environment. Our clients regularly request us to assess all manner of floating structures with a combination of structural dynamics, time domain simulations, linear and non-linear stress analysis, fatigue and buckling checks. In addition our engineers can model gaps and contacts in structures which may be a wide range of materials including, steel, aluminium, composites even soils. Applications include:

    • Mooring of vessels in tandem alongside a quay, such as in the case of a floating LNG terminal
    • DP capable vessels working in track target mode close to an FPSO or FSO
    • STS operations where a smaller vessel may be in the lee of a larger vessel
    • Heavy lift operations with multiple floating cranes

    Multibody Hydrodynamics

    As a basis of many other analyses, the derivation of accurate and reliable hydrodynamic coefficients and properties of vessels and offshore structures is critical. At Longitude, we apply this experience through the use of in house macros and sub routines developed over many years which include.

    • Advanced Hull form modelling
    • Fine Mesh control
    • Validation of Response Amplitude Operators (RAOs) and Quadratic Transfer Functions (QTFs)
    • Calculation of vessel motions and accelerations suitable for design and operability analyses.
    • Mooring analyses
    • Operability Assessments

    Dynamic Simulations

    Longitude is highly experience in undertaking a range of dynamic analyses for all vessel types or other offshore structure throughout the marine industry.

    These analyses typically take the form of structural dynamics, where a time history approach is taken to identify the response of a structure to a pulse or dynamic loading. Alternatively, we look at the hydrodynamics, where we assess in detail the response of an offshore structure to a seastate. We cover:

    • Specialist Dynamic Simulations
    • Structural Dynamics Analysis
    • Hydrodynamic Analysis
