SCOPE OF WORK

Basic & Detailed Design Stages

  • Structural verification of the integrated deck during integration of new modules for Rosalirio and Girri projects
  • Derive an optimized PFP mapping
  • Define new specifications to replace bearing devices

SPECIFICS

  • Consider the full structural model of the FPSO (hull, integrated deck and modules) under annual and centenal environment conditions to identify the impact of the additional loads coming from added modules on the structural strength of the integrated deck
  • Suggest modifications and reinforcements
  • Conception of a procedure to study PFP mapping of the integrated deck, cell by cell, element by element
    Done in partnership with MAREAL

PROJECT

POLAR POD PROJECT – 2015

CLIENT

SCOPE OF WORK

Basic Design Stage

  • Checking structural integrity of the steel truss under extreme environmental loads and cyclic loads (fatigue)
  • Vertical and horizontal positions are considered

SPECIFICS

  • The model contains both hull shape and trusses
  • Hydrodynamic loads on the hull shapes (ballast and floater) are mapped to the structural nodes of the truss and are accounted for automatically in the stiffness analysis
    Done in partnership with MAREAL

PROJECT

GUINARD ENERGY PROJECT – 2017

CLIENT

SCOPE OF WORK

Detailed Design Stage

  • Stability calculations during ballasting operation
  • Ballasting and deballasting procedures

SPECIFICS

  • Study done as a succession of equilibrium positions and also in time domain
  • Air pressure is taken into account in the ballasting of the compartments
  • Vents and flood valves are considered in the model at the correct location

PROJECT

SPUD CAN INSPECTIONS – 2008 & 2013

CLIENT

lamprell

SCOPE OF WORK

Detailed Design Stages

  • Support of Jackup on one or two barges for spud can inspection operation
  • Structural verification of the jackup hull and barges

SPECIFICS

  • Consider a simplified structural model for the jackup and barges
  • Model the jackup with legs as separated parts of the body jackup so that their elevation can be modified independantly
  • Compression only connectors are located betwen the barges and the jackup hull
  • Static analysis
    Done in partnership with GPMC
