 FAST FRAME
- Low risk; eliminates outriggers, 'hanging off' and manual rigging changeovers.
- Significant reduction in vessel and project time.
- Eliminates long followers by lowering the height of the C.O.G., thereby, reducing the overall weight and improving stability.
- Eliminates followers accurately orientates pile (and tethers) towards FPSO centre.
- Transportable by road in components.
- Compact and easy to maintain.
- Levelling system supplied as optional.
- Can be used with impact or vibratory hammers.
- Only light craneage required.
- Can be deployed with pile pre-installed.
- Accommodates different diameters of pile.
- Can be used with mudmat extensions for varying soil conditions .
An innovative sub-sea piling system which cuts offshore installation times has been successfully proven during the summer of 2000 in the North sea.
Known as Fast Frame the system has been designed and patented by Sea Steel for the installation of mooring riser and initiation piles ranging from 20" to 96" in diameter. The system has been used on a number of projects in the UK and Norwegian sectors.
The key feature of Fast Frame is the ability to drive piles to full penetration in a single operation. The frame is placed on the seabed with the pile and tethers connected. As the pile is driven down a ring welded around its outer surface, near the top of the pile, triggers the frame's latching mechanism, enabling the halves of the hinged guide sleeve to fall open. Driving is then completed, the tether lying in the open bay of the frame with the pile correctly orientated.
As the frame is lifted from the seabed the sleeves automatically close and re-latch, ready for the next pile to be inserted without retrieval of the frame to the surface.
Piling operations can be performed in less than a third of the time needed for conventional methods, reducing costly vessel time, eliminating WROV intervention and making operations far safer.
