Model Testing

The Versabuoy technology has been developed and refined through multiple engineering studies and scale model test programs. The introduction of the connections between the buoys and topsides results in a multi-body class numerical analysis problem, where the individual bodies are able to move independently of each other in one or more degrees of freedom. Specialist tools (WAMIT, AQWA, and SESAM) have been available for 5 years plus, allowing for independent engineering assessments to be performed. The extensive model test program completed has provided a large database of multi-body test results under a wide range of loading conditions, and which has been used to benchmark and validate the various analytical tools used.


Figure 1 shows a Versabuoy platform undergoing testing in the Gulf of Mexico 100-year hurricane wave conditions.


Table 1 presents a summary of key response parameters measured during the model
test program.


A key attribute of the system is the low topsides motions experienced even under extreme hurricane storm conditions. These low motions support another unique operating capability of the technology, that of being able to rigidly (simply) connect two or more Versabuoy platforms together to provide very large offshore platforms (or bases), or a phased development approach where additional platform modules are combined over the life of a development.
