Tail hose is part of the floating hose string. It connects the tanker rail hose and the mainline floating hose. Sometimes, it can also be connected to the reducer hose instead of the mainline hose. This happens when the reducer hose is added to the floating hose line. This tail hose is single carcass. For double carcass tail floating hose, please click here to see more. DeepSee provides premium design and high-quality manufacture for both double carcass and single carcass marine hoses.

Technical Analysis
When designing marine hoses, we do dynamic analysis and hydrodynamic calculations with the help of OrcaFlex. Dynamic responses of marine hoses are simulated under environmental loadings like wind, currents, and waves. For hoses are applicated in mooring systems like SPM, we analyze tension of mooring lines in different sea states and mooring point’s motion and displacement under various dynamic loads.
By doing Finite Element Analysis (FEA) with Abaqus, we focus on both the overall behavior and local details of the marine hose. We simulate temperature changes and hydrodynamic effects and analyze static and dynamic structures. Strain, stress, and deformation of the hose assessed. We can obtain accurate data, such as flexural, tensile, and tensional stiffness of the hose, rubber strain, cord tension, and reinforcing steel stress.
Import the ABAQUS static analysis results into the fatigue analysis software fe-safe, select the fatigue analysis theory, set the material parameters of each structural layer, load the above load spectrum, and we can get the fatigue analysis results.
