Properties of barge is an important factors for offshore module transportation.

While transporting the huge modules, these barges experience rolling,pitching, and heaving motions from the combined action of waves, wind etc.

The intensities of these motions largely depend upon the particular sea-rout considered for transportation, prevailing sea conditions head winds, size of barge, design draft, geometry and weight of modules being transported.

ISB Engineering has been experienced to conduct feasibility studies,Conceptual,basic and detailed design including :

  • Dynamic behavior in fluid-structural interaction
  • Hydro-dynamics loads studies
  • Detailed Design & Studies of combined action of waves for Offloading Barge Transportation and Modular Load-Out

Proven as risk minimizer,cost saver and facilitator to many EPCI as well Oil companies, ISB Engineering has experienced of more than 12 (twelve) years to conduct Feasibility Studies,Conceptual,Basic and Detail design for platform elements transportation as well as its installation procedures such as Loadout, Transportation and Installation Operations).

ISB is capable to conduct installation engineering for :

  • Tension Leg platforms, Spar, Compliant/Tower platforms & Seastar Platforms
  • Semi Submersible & Submersible platforms/rigs
  • FPSO,Drillships,FPU & Floating production systems
  • Jacket & Topside
  • Concrete Gravity Structure
  • Soil investigation for Platform Foundation
  • Topsides Transportation
  • Topside to jacket attaching pre-commissioning & commissioning support

Our engineers are familiar with installation engineering codes such as :

  • API RP-2L
  • API 1996
  • ASTM grade A36

We design and analyze offshore platforms by considering many factors, including :

  • Initial transportation Study
  • In-place of 100-year storm conditions (or with other parameters as needed)
  • Soil Characteristic investigation & Geotechnical Data Gathering
  • Failure Consequences
  • Installation Engineering Standard&Code check
  • Other Specific Relevant Studies suited to client needs/projects

ISB has completed a number of jacket/topsides installations for major EPC contractors in the region.

The services offered included the following:

  • Load out
  • Sea fastening and Transportation, Barge Stability
  • Grillage Design
  • Barge Strengthening
  • Installation
