Enriched by our vast industrial experience in this engineering business, we provide qualified and competent personnel to support your operations in the areas of shipbuilding, repair, heavy lifting & the transportation industry. We can minimize your administrative obligations so that you can focus solely on operational duties. We can provide our experts in a range of disciplines, including

• Structural design of floating offshore units
• Production design and drawings
• Feasibility study for conversion engineering
• Lifting analysis for offshore structures
• Finite element analysis
• Buckling and ultimate strength analysis
• First-principle calculations for scantlings, sea fastening,
• lashing
• Linear and non-linear analysis
• Vibration analysis

Engineering the ballast & sea fastening calculations, checking local & global strengths of the barge or the heavy-lift vessel during transportation, the cargo being transported is subjected to dynamic loads due to waves from the ocean and subsequent vessel motions. Engineered sea fastening prevents the potential
loss or damage to cargo during transportation. Dynamic loads used to design the tie-down members are either based on MWS standard motion criteria or maximum motions the vessel could undergo while experiencing the worse anticipated sea state along the tow route deduced from vessel motion response analysis. When it comes to the safe transportation of cargo, we perform the

following operations:

A simple subsea lowering analysis is conducted for vessels as recommended by DNV-RP-H103, or a detailed fully coupled dynamic analysis is conducted including all important bits of lowering or recovery operations such as lift in the air, lift through splash zone, lift in the water, lowering on to the seabed and lifting off from the seabed. These tests help estimate the dynamic loads on slings and associated equipment during the lowering or recovery operations while also establishing and quantifying the restrictions for installing or recovering subsea structures. Launching substantially large or heavy jackets from the launch barge helps them float without challenges. Jacket launch analysis aims to provide the

following checks:

•  Barge ballasting requirement for arriving at launch floating condition
• Jacket push/pull force required to commence launching
• Rocker arm reaction loads estimation

•  Jacket launch trajectory and dive depth
•  Reserve buoyancy analysis
•  Sensitivity studies for jacket COG positions and friction coefficients
