All the benefits of the Gall Thomson Petal17 MBC but offering:
- Up to 30% reduction in axial load
- Installed length reduced by 60%
Shown: PetalC in operation
PetalC offers distinct operational benefits for the following applications
- FPSO and FSO export reeled or catenary hose strings.
- Floating hose strings at SPM CALM/SALM Buoy terminals.
- FPSO and FSO floating hose strings.
- Underbuoy hose strings at SPM CALM/SALM Buoy terminals.
Reduced installed length
The installed length on a PetalC is reduced by 60% compared to the Petal17 Marine Breakaway Coupling.
This unique feature is achieved by inserting the PetalC cartridge inside the hose fittings.
Reeling considerations
During the process of winding the hose on the FPSO reel, the MBC is subject to high bending moments and axial loads.
To ensure integrity during the reeling and un-reeling process, the MBC can be designed with titanium transit bolts in certain cases.
The titanium transit bolts need to be removed during the deployment of the hoses and re-installed prior to reeling the hoses and the MBC back onto the FPSO reel.
The PetalC solution
The reduced installed length and optimised geometry of the PetalC caters for the high bending moments generated by these operational parameters and removes the need for transit bolts*.
This means PetalC can be used in line with established offshore operational parameters.
*On occasion, an operational task may determine the use of transit bolts.
