Consultancy

PAFA Consulting Engineers offers a wide range of skills centred on structural engineering, structural reliability analysis (SRA) and naval architecture.
Structural engineering expertise covers:

  • Design for both strength and fatigue (spectral where necessary) of buildings, bridges, fixed steel offshore structures, floating structures, wave energy devices
  • Assessment of damage from construction in the form of welding residual stresses and associated deformations (out-of-straightness, out-of-plane), and accidents and abnormal events
  • Ultimate strength of components and systems including large deflection (geometrical) effects and material non-linearity. The effects of damage on ultimate strength can also be addressed
  • Flaw/defect assessment to BS 7910
  • SRA for component and system reliability determinations, partial load (action) and resistance factor derivations
  • Floating offshore structures – Green water and wave slam, Weather-sensitive operations, Shuttle tanker – FPSO impact forces, FPSO design risk assessment, FPSO survey requirements, ISO 19904-1 and ISO 19901-7 development, Schiehallion design basis review, TLP for intermediate water depths and limited payload, e.g. wind turbine (patented), design of a large mid-water steel structure for riser supports in extreme water depths, barge design specification for procurement as a transhipment facility for natural gas
  • Floating marine structures – dock and lock gates, large caissons acting as floating dock gates for submarine outfitting facility, floating dock and crane support for submarine servicing, multi-pontoon and link- span design for Navy and Coastguard support base, design loads and safety factors for the strength of tanker mooring equipment (within OCIMF publication on mooring equipment guidance), extensive assessment of recorded and simulated loading conditions and associated structural modelling and SRA of Thames Barrier rising-sector gates in support of design life extension
  • Helideck design and detailed assessment involving both aluminium and steel decks, and testing of wheel loads on stiffened steel deck and corresponding simulation using non-linear analysis
