FPSO offshore hose reel application

PetalC has all the benefits of the Gall Thomson Petal17 MBC but also offers:

Up to 30% reduction in axial load on the most critical breakstuds.
Installed length reduced by 60% therefore improving compactness: resulting in an extremely robust Marine Breakaway Coupling.

No need for transit bolts unless specifically required

PetalC delivers distinct operational benefits to the following applications

FPSO and FSO reeled hose strings
Floating hose strings at SPM CALM/SALM Buoy terminals
FPSO and FSO Floating hose strings
Underbuoy hose strings at SPM CALM Buoy terminals

4 key operational advantages of the PetalC

1. Geometry delivering enhanced MBC integrity

PetalC works with the advantages offered by the hose nipples so that overall integrity is maintained within a greater range of operational handling scenarios and extreme weather conditions. The unique profile of PetalC and its integration into the hose nipples adjacent to the MBC, reduces axial loads by up to 30% on the most exposed breakstuds.

2. Installed length reduced by 60%

The installed length of the 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 nipples.

The geometry of PetalC and its reduced installed length contribute to increase protection to breakstuds against bending moments.

3. Axial load reduced by up to 30%

The unique combination of the PetalC installed length and adapted geometry delivers a reduction in axial loads of up to 30% on the most critical breakstuds

Critical breakstuds are those that are most exposed to a bending moment at a particular point in time.

Due to precision manufacturing, rigorous quality control and testing procedures, Gall Thomson breakstuds have a reputation spanning nearly 50 years for delivering consistent field service reliability.

4. No bespoke or complex MBC monitoring systems required

The function of the Gall Thomson MBC is to automatically respond to emergencies without layers of monitoring or extra control systems.

Petal C is fully mechanical, self-energised and self-contained. Monitoring the PetalC with sensors is not required.

A Gall Thomson MBC therefore exists to simply deliver a dependable solution within a predefined set of emergency scenarios.

Minimising the variables required for managing an MBC therefore reduces the risk of unforeseen complications or operational malfunction due to any dependence on components beyond that of the MBC.

Gall Thomson MBCs offer the optimum solution in protecting offshore hose transfer systems.

An evolution of designs made possible through decades of on-going analysis of field verified performance data.
