Concept Selection

Screen production scenarios to determine what aspects of flow assurance influence design

Broad experience with Deepwater projects integrates knowledge from a worldwide portfolio of projects currently being designed and those in production

System Selection/Pre-Design during System Selection

Provide analyses and recommendations that ensure the installed systems can be operated without flow-related downtime

During pre-design, we take the prescribed subsea hardware and determine the �envelope� of conditions during which the system can be expected to operate

Make recommendations as to when other system components such as subsea accumulation are required

Determine the impact on topsides equipment to flow assurance related operations, such as slugging and flowline depressurization

Work with operations staff to develop detailed operating procedures that will ensure no flow - related problems occur at well unloading, start-up, normal production, or at shut-in

Design

During design, the Applications Team can assist in developing integrated subsea/topsides dynamic models that will be used during operations training and process planning

Surveillance, Training and Methodology

As you plan your surveillance program, we provide specification and development of allocation and flow-assurance prediction tools. In conjunction with subsea measurements, these tools can be used to help operators understand when flow-related problems should be expected, or when operator intervention is required.
