The Morison equation is widely used to estimate the loads by surface waves on cylinders. formulation and coefficients determination method of original work et al. are revisited, it found that there exist some issues yet be explained, e.g., larger uncertainties in drag coefficient underestimated maximum moments. Numerical simulation with a similar configuration reproduce these results help disco...

Coupled dynamic analysis of a floating offshore wind turbine (FOWT) is predicted with in-house ITU-WAVE computational tool. The hydrodynamic parameters are approximated time marching boundary integral equation whilst aerodynamic solved unsteady blade element momentum method. In addition, forces on FOWT due to mooring lines quasi-static viscous effects included Morison equation. FOWT’s blades co...

The discussion of hydrodynamic forces becomes an important issue in determining the dynamic behaviour Submerged Floating Tunnel Bridge (SFTB) structure. As stated Morison Equation, are affected by kinematics water particles, but up to this date, there only a few discussions for curved tube applications. This paper discusses effect curvature radius and depth level on get correction factor straig...

The vibration control problem of offshore jacket platforms is studied. According to Morison equation, the total wave force acting on the offshore structure is obtained and is generated by an exosystem. Considering the nonlinear interaction of pile-soil, which is described by a fifth order anti-symmetric polynomial, the nonlinear dynamical model of offshore platforms affected by the wave load di...

Abstract Scholars have suggested that Cassius Dio’s Roman History was among the Greek sources used by 16th century polemicist Sir Richard Morison in two of his treatises from 1530s. This short article shows this is not case. Rather, can be seen to borrowing Seneca’s De Clementia and Politian’s Latin translation Herodian’s Empire after Marcus Aurelius . conclusion may cast some further light on ...

Abstract Free-standing hybrid risers are vertical slender steel pipes that commonly used in the oil and gas industry. These structures subjected to complex hydrodynamic loads results fatigue damage. The tidal forces develop on Freestanding Risers (FSR) with buoyancy cans ( BC ) because of varying outer pipe dimensions investigated this work. study considered riser diameters 0.2, 0.3, 0.5 0.6 me...
