Following the chartering of the Greatship Rachna and the commissioning of its latest heave compensated geotechnical drilling rig in Q2 2019, EGS secured a project for the largest international offshore wind developer off Changhua County in Taiwan. The Scope of Work consisted of acquiring PCPT data and undisturbed samples in boreholes over 90m deep for the WTG foundation design study. The project was successfully completed on time at the end of September and without any HSE incidents.
The latest EGSA-20 drilling rig mobilized onboard the Greatship Rachna in accordance with LRS standards was designed and fabricated in Singapore in Q2 2019. EGS opted for a twin derrick design with innovative safety features to improve working conditions for the drilling team by providing a safer environment on the drilling floor. The various tooling available onboard has been specially selected to tackle challenging geological conditions on offshore windfarm sites in Taiwan, Japan, and South Korea.
In addition, the twin derrick design provides an ideal platform to deploy a 200kN Seabed CPT through the moonpool to further increase productivity on large windfarm projects in areas where typhoons and monsoonal weather conditions severely restrict operation windows.
Greatship Rachna, which has proven to be an excellent platform to work in the challenging conditions of the Taiwan Strait, will be available for geotechnical work in the Asia-Pacific region from Q1 2020.
