Design Issues
Typical FRP pipe is reciprocally filament wound with a fiber angle of ±54.75° relative to the longitudinal (0°) axis. This architecture satisfies stress loads in both the circumferential (hoop) and longitudinal (axial) directions for most pipes and pressure vessels. It withstands the in-use pressure, ther

Composite Accumulator Bottles Perform In Service
A riser tensioning system for a TLP consists of a tensioning ring and framework, with four to eight hydraulic cylinders — each with an attached pressure vessel or “accumulator bottle” — to support and allow movement of the rigid riser pipe. Installed in the riser wellbay, this primary structural system is desi
