PARIS – Technip and Bluewater have signed an agreement to jointly market the Spiral Stacked Turret (SST) for floating units.
SST is a flexible hose-based alternative to the traditional mechanical swivel stack that transfers flow from the moored turret of a floating unit to its topside deck, which rotates in the prevailing weather conditions.
The SST, however, allows each flexible pipe to wind and unwind onto and off of a conical tray, which the partners claim leads to significant rotational freedom and extended service life. It is best suited for high pressure and large capacity flow transfer systems, they add.
Technip will design and supply the upper fluid transfer system with Bluewater designing and supplying the lower turret mechanism. Both companies will jointly market the SST and offer it to third party floater owners worldwide.
Technip plans to manufacture the fluid transfer hoses at its flexible pipe plants in Le Trait, northern France, Vitoria, Brazil, and Tanjung Langsat, Malaysia. Bluewater plans to integrate the SST on its own FPSOs, provided the application is suitable.
