Details
FSRU is the abbreviation of Floating Storage and Re-gasification Unit, usually also called LNG-FSRU. It is a special equipment integrating LNG(liquefied natural gas) reception, storage, transfer, regasification and export. It is equipped with propulsion system and has the function of LNG carrier.
The main function of FSRU is LNG storage and regasification, which is to transfer LNG received from other LNG ships to the pipeline network for natural gas users after pressurization and gasification.
The facility can be used as an alternative to conventional land-based LNG receiving stations and as an ordinary LNG ship. Currently, it is mainly used as LNG receiving and gasification facilities, LNG transportation and gasification ships, platform-type LNG receiving terminals and gravity-based offshore receiving facilities.
When we produce Floating Rubber Hose For NG for FSRU units, the main design considerations are as follows:
1. Manifold location and hose selection
Manifold location: deck/side
Hose selection: Different stiffnesses should be considered to transfer stress from float tubes to manifolds.
Deck: Fence pipe
Ship side: lifting, one end reinforced pipe
2. Length of fence hose
The horizontal distance of manifold flange and dry chord height of FSRU under light load determine the design of pipeline length, which must avoid stress concentration in joint part and ensure the transition from rigidity to flexibility.
3. Length of reinforcing tube at one end
Vertical distance from manifold flange to water surface under light load of FSRU, stress concentration at joint must be avoided.
4. Overall length of pipeline
Vertical distance from manifold flange to water surface under light load of FSRU, horizontal distance from first hose near water surface to connection pipe on shore, vertical distance from reinforced hose to water surface at one end of platform on shore.
5. wind, wave and current loads
Wind, wave, and current loads determine the design of hose torsion, tension, and bending loads.
6. flow and flow rate
Based on flow or velocity data, calculate the appropriate hose bore.
7. Transport medium and temperature
8. General parameters of hose
Internal diameter; length; working pressure; single or twin; hose type; minimum residual buoyancy; conductivity; flange class; flange material
