DYNAMIC POSITIONING (DP) FLOATOVER METHOD
COSCO SHIPPING Heavy Transport is the industry leading pioneer of the dynamic positioning floatover method. We have a proven track record of safe and successful float-over installations around the world using our state of the art purpose, built DP2 semi-submersible vessels. We provide our clients with high quality packaged DP floatover installation solutions.
ADVANTAGES OF DP FLOATOVER INSTALLATIONS
- No Anchoring and Minimized Marine Spread
- Less Weather Exposure - Shorter Window Required
- Quick Installation Time
- Less Interference with other Marine Operations
- Excellant Maneuverability
- Independent of Water Depth
- Not limited by an Obstructed Seabed
- Greater Increased Operability
Loadout
Loadout of the topside module onto our Vessel takes place by lift-on, roll-on or skid-on method.
Pre-Installation
After the seafastening is removed, the Vessel is de-ballasted and maneuvered into the Jacket using the fully redundant Class 2 Dynamic Positioning System.
Transport
The Vessel sails directly to the discharge site along the quickest and safest route.
Installation
As soon as the Vessel is exactly in the correct horizontal position, the Vessel ballasts quickly, bringing the Topside in contact with the Jacket. When there is a sufficiently large gap between the Vessel and the Topside, the Vessel maneuvers out of the Jacket.
