Abstract: In an attempt to meet the supply and increase the effectiveness of the distribution of fuel to the Madura and East Java regions which previously used Single Point Mooring (SPM), another option is needed, namely the design of a bulk dock facility located at the Camplong Fuel Oil Terminal (TBBM), East Java. This wharf is designed to be able to receive the tanker “MT Kurau” with a capacity of 6500 DWT. This final project discusses the design of the dolphin type liquid bulk dock consisting of a loading platform, breasting dolphin, mooring dolphin, and trestle with structural elements consisting of beams, plates, pile caps, and piles. The initial design or initial design produces the dimensions of the pier and the structural elements of the pier based on the dominant loading on the pier. The dock structure is then modeled using structural software and optimization or changes to the dock structure are carried out to obtain UCR and deflection values that meet the design criteria used. The output of the structural modeling after obtaining the optimum design is the forces in the concrete elements and the bearing reaction of the pier structure. The internal style is used in the next stage, namely the design of the reinforcement of the pier structural elements. Furthermore, the required pile depth calculation for each structure is carried out based on the laying reaction obtained from the structural model and soil condition data at the dock location. The designed wharf has a length of 15 m and a width of 10 m for the loading platform structure, 912 m long and 6 m wide for the trestle structure, 3,5 m long and wide for the breasting dolphin, 3 m long and wide for the mooring dolphin, and 40 meters long. m and 1,2 m wide for the catwalk. The five structures have the same floor elevation which is +5,2 m from LWS. Based on the optimum structural design, used piles with a diameter of 609,6 mm with a thickness of 11.13 mm on the loading platform structure, piles with a diameter of 508 mm with a thickness of 12 mm on the trestle structure, piles with a diameter of 711,2 mm with a thickness of 14 mm on the structure. breasting dolphin, piles with a diameter of 609,6 mm with a thickness of 16 mm on the mooring dolphin structure, and piles with a diameter of 355,6 mm with a thickness of 12 mm on the catwalk structure. In the loading platform structure, the piles need to be driven to a depth of 14,58 m below the seabed, in the trestle structure, the piles need to be driven to a depth of 6,12 m below the seabed, in the breasting dolphin structure, the piles need to be driven to a depth of 10,77 m below the seabed, on the mooring dolphin structure, the piles need to be driven to a depth of 7,16 m below the seabed, and on the catwalk structure, the piles need to be driven to a depth of 7,55 m below the seabed. The results of this final project are the dimensions of the pier structure and pier structural elements, facilities for berthing and mooring of ships, details of reinforcement for pier structural elements, and the depth of pile driving.
