Subsea tree recovery and redeployment: Brazil's experience.

Eighteen trees are examined from the Campos Basin in Brazil. The reasons for recovery are examined and the time involved in completion, reinstallation and the tree maintenance operators are discussed. Tree maintenance was a very minor operation and the redeployment was generally performed in slightly less time than the initial installation The data presented are useful for estimating field operating costs of future subsea field developments. Additionally, the recommendations given, based on the experience analysed, will help design completions that are faster and less expensive to install and maintain, particularly for deepwaters.
