2. TCMS® BENEFITS Uses standard tankers
Utilises standard mooring equipment
No internal turret
No dry docking of tanker required
Can be disconnected and redeployed
Fast-track commissioning and deployment
Allows normal vessel rotation with wind and current (weathervaning)
Proven in North Sea, Atlantic, Mediterranean & Far East
The worlds most cost-effective mooring system

3. HOW DOES IT WEATHERVANE WITHOUT A TURRET?

5. PRODUCTION & MOORING TCMS®

16. cast in R4 material
huge factor of safety against strength and fatigue
padeyes for “standard” shackles

20. DISCONNECTABLE
System is designed to be disconnectable in emergency or in event of extreme weather conditions.
During disconnection a 300T Winch is used for lowering the system to the seabed.
Risers & Guide frames layed on Seabed.
Vessel then free to move off location.
