Major design advantages:
- It eliminates the need for submarine hoses and provides a simple fluid transfer via jumper hoses from the tower to the tanker
- It provides direct access to the tower structure from the storage tanker
- Only minor tanker modifications are required
- All mechanical equipment is located above sea level
Principal components:
- Tower: This serves as a rigid anchoring point for the permanently moored tanker and accommodates the fluid swivel. It also provides a base for the turntable, to which the tanker is connected.
- Mooring Components: A wishbone or a hawser arrangement to connect an offloading tanker to the tower.
