Abstract—Float-over installation method has been recently used
to install topsides onto jacket type of platform. As a viable
alternative to the traditional lifting installation method, this
method uses a float-over barge to transport and install topsides
onto the platform by ballasting operations. This method
eliminates the use of heavy lift vessel, and thus is economical for a
platform with heavy topsides. The motions of the barge during
float-over installation are critical and must be analyzed to ensure
successful operations. For the study presented in this paper, the
model tests for a float-over barge were conducted on a model
following Froude Scaling Laws with geometric scale ratio of 1:50.
The model was tested in random wave sea states with varying
drafts. The result of the physical modeling study are then
analyzed and presented in terms of Response Amplitude
Operators (RAOs) for surge, heave and pitch. The results
quantify the importance of design parameters such as draft or
ballast condition in the response of float-over barge
Keywords-float-over barge response, model test; Response
