Wood Group Kenny has been awarded a design contract by Italy’s Saipem for the engineering analysis and configuration of a riser system for the deepwater Sapinhoa Norte pre-salt field offshore Brazil.

The award for the Steel Lazy-Wave Riser (SLWR) system follows tender support work and conceptual riser engineering that Wood Group Kenny provided to Saipem in the original bid stage of this project. Saipem has since been awarded the engineering, procurement, fabrication, installation and pre-commissioning of the SLWR at the Sapinhoa Norte field, which lies around 300 km offshore.

Wood Group Kenny’s project scope includes extreme response analysis, wave fatigue analysis, vortex-induced vibration and interference analyses. This will be carried out in two stages: a fast-track front-end engineering design followed by a detailed design verification.

The Sapinhoa North field will require 27 risers, with at least 12 to be rigid, in addition to a free-standing gas export system and pipeline end terminations.
