Stinger IV-BGL (Petrobras)

The BGL barge is used for PETROBRAS for transport, lift operations and pipelay, when equipped with a stinger, and the Stinger IV is the biggest constructed for this vessel. Oceânica worked together with IPT to evaluate BGL’s weight and centers, numerical and experimental motion, and to perform the structural analysis of the stinger.

Oceanica’s scope of work:

  • BGL’s weight and centers estimation
  • Numerical and experimental evaluation of the RAO
  • Calculation of Morison loads on the stinger in waves
  • Structural analysis of the stinger
