In offshore structural engineering, buoyant leg storage and regasification platform (BLSRP) is one of the recent innovative structural forms that is archived to suit industrial requirements. Proposed platform consists of a deck, which is connected to six buoyant leg structures (BLSs) through the hinged joints while BLS units are connected to the seabed using taut-mooring tethers. The conceived structural form is a hybrid concept, which restrains transfer of both rotational and translational responses from the BLS units to the deck and vice versa. The main advantage is the improved functionality in terms of increase in the storage and regasification capacity of liquefied natural gas. Experimental investigations are carried out on a scaled model of BLSRP (1:150) under regular waves for two different wave approach angles. Free vibration tests are carried out on the scaled model to estimate the natural periods; results show that BLSRP resembles a tethered compliant structure like tension leg platform (TLP) except showing relatively higher stiffness in the yaw degree-of-freedom. Geometric design of BLS units ensures a good recentring capability of the deck in all the translational degrees-of-freedom. Lesser heave response of deck, in comparison to that of the BLS units ensures comfortable and safe operability. Attempted study is a prime-facie towards design and development of offshore production and process platforms that can reduce the cost of oil and gas exploration.
