Jumbo, Technip Complete 2,500-Meter Installation

Technip USA, supported by its contractor Jumbo Offshore, have completed the installation of five free-standing hybrid risers, known as FSHRs, for the Petrobras America Inc. Cascade and Chinook ultra-deepwater projects in the Gulf of Mexico.

Transportation of the five buoyancy cans was handled by Jumbo’s Fairplayer. Installation was led by Technip, whose construction vessels Deep Blue and Deep Pioneer, together with the Fairplayer, installed the buoyancy cans and risers in winter conditions and with zero health, safety and environment recordable.
 
The five FSHRs are the deepest risers of this type installed to date.

The Fairplayer, which is one of Jumbo’s two DP2 offshore Heavy Lift Vessels), loaded the buoyancy cans from Technip’s yard in Pori, Finland, and transported them to the Cascade and Chinook offshore location in the Gulf of Mexico. There, she met up with Technip’s Deep Blue and Deep Pioneer to commence installation.

The scope of work was coordinated via Technip Offshore Construction Managers and was assisted by key members of Technip’s crew onboard the Fairplayer.

The installation started with the Deep Blue deploying the riser, followed by the Fairplayer with a wet handshake, lifting the 2,300-meter riser with the fore crane and placing it in a hang-off structure for connection to the buoyancy can. The whole assembly was then overboarded and lowered safely through the splash zone. Jumbo Offshore broke its own record, lifting over 700 t load offshore.
