Development of load-out design methodology and numerical strength evaluation for on-ground-build floating storage and offloading system

The load-out operation was carried out using two semi-submersible barges connected together by rigid frame structures. The ballasting operation of double barge unit (DBU) can be controlled like a single barge using a load master control software (LMC). Throughout the operation, relative deflection in the form of DBU connection frames was monitored and DBU motion were analyzed and compared to our model test result. After 4 years of dedicated research, we were finally succeeded in confirming the technology of Ground Build design of floating structure, construction, load-out and float-off.
