| Abstract: | Offshore platforms become increasingly integrated and modular with large weight and size. Floatover installation method which is more suitable for the installation of large topsides develops rapidly. This paper presents the field measurement techniques used in the floatover installation of the Liwan 3-1 mega topsides. The motion measurements of barge and the environmental field measurements, etc., were conducted to guide the entire floatover operation. The field measurement data ensured the floatover operation to be performed as rapidly as possible and coincident with safe practice. Numerical method is used to simulate the mating operation process, and the calculated results are compared with field measurement showing that they have the same pattern of changes. |
