March 2019, the Mid-Term Project Review on the Liuhua Compliant Tower Pre-FEED at OTL Houston office by a CNOOC delegation led by Chief Engineer Mr. Zhigang Li has been conducted. OTL presented the design results for the configuration and feasibility cycles, and have had deep technical discussions with client on various design processes, issues and conclusion. OTL’s work so far concluded that Compliant Piled Tower concept is feasible for the CNOOC Liuhua field development and CNOOC delegation agreed. OTL is striding to the next optimization cycle and expect a better configuration can be reached with significant steel saving. Compliant Tower concept is an advanced very deepwater fixed offshore platform concept requiring high knowledge and skill for the analysis and design.
