Page of PRESENTATION GENERAL INTRODUCTION This guide has been drawn up within the framework of the activities of the PRODUCTION OPERATION Part of the Ultra Deepwater UGF R D Project It is based on experience acquired within the R D activities UGF and Ma? trise des Dépôts and within the Deepwater ?eld development projects The document has involved specialists from TDO EXP TDO TEC SCR RD and SCR ED This guide is intended for anyone seeking information on Flow Assurance related to Deep O ?shore developments especially peoples involved in Field development Design Construction and Production phases The aim of this guide is to highlight concerns related to multiphase ow production to give the level of knowledge and understanding of phenomenon explain and detail the studies to be carried out to handle and quantify associated risks and ?nally describe solutions to be implemented in order to prevent or remediate the problems As subsea production is a key element to deepwater production this document focus on problems and solutions developed for subsea systems More traditional developments with dry trees and direct access meet similar constraints and solutions as those
