![]() It is easy to make mistakes in input data. This paper describes coastal civil engineering and naval architecture good practices applied to design optimization of concrete caissons, typically constructed by slipforming.Īlways check results with experienced engineers and naval architects. Response at intermediate attack angles is interpolated. Mechanical admittance is calculated and dynamic response is computed. The Excel package goes on to calculate motions of the floating structure in waves, based on closed form analytical solutions.įor each degree of freedom, the diffraction and Froude-Krilov forces are discretely calculated for wave attack in the primary plane of motion, at a range of wave periods. The installation requires afloat stability checks as the caisson is removed from the semi-submersible barge. Wave forces and safety factors against sliding and overturning are computed with Excel and shown in the Excel chart below: This lecture was presented at the ASCE COPRI 2018 Houston Chapter Conference.Ī cross section through the main breakwater is shown below: WAMIT, User Manual Version 7.2 (2013).The full lecture can be viewed at CAISSON DESIGN VERIFICATION.

The floating breakwaters of different spatial layouts have sheltered internal gaps/moonpools when compared to their conventional counterparts. ![]() ![]() In this paper, both the hydraulic design and geotechnical design are discussed. This paper investigates the effectiveness of floating breakwaters consisting of two barges (L-shape), three barges (U-shape), four barges (barge frame), and conventional single floating breakwater.
