The tanker rail hose connects the tanker manifold branch and the tail hose. Lifting lugs are included in this product. This reinforced floating hose is used for FPSO offloading too.
In most offshore mooring systems, tanker rail floating hose is used to connect the ship's manifold and the floating hose strings. Its center lays on the tanker rail. This part has minimal buoyancy compared to the two sides. Though this hose looks like a dumbbell, two ends are not exactly the same, no matter from the size or inherent buoyancy. To provide more flotage for the valve and coupling device, the side that connects the tanker holds more buoyancy than the other side outboard. Connecting the bigger end to the tanker manifold can help to protect the equipment. Two white stripes are a sign of the tanker end. Proper installation and use will make hoses more durable and allow the transfer process to be safer and more efficient.
The end of tanker rail hose that connects with either the tanker or FPSO unit is reinforced. Generally, hard pipelines, no matter underwater or above the sea, are connected with marine hoses that are reinforced. Make sure to connect the side with white bands to the hard pipes (FPSOs and tanker). This can exert its advantages to the best.
Our tanker rail hose is safe and durable. It is the first hose to connect FPSO vessels and the shuttle tanker. Its structure can endow FPSO oil and gas offloading with a good start.
We can make double carcass tanker rail hose as well. Click to see.

Technical Analysis
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.
By using the hydrodynamic software ORCAFLEX, we calculate floating hose data, such as bending moment, torque, and tension, and compare the results with design allowables. Environmental loads such as wind, wave and currents, as well as the excitation oscillations of FPSOs, tankers or moored buoys, are considered.
