Answer 1

Criteria for Selecting Offshore Structures :

Criteria for selecting offshore structures mainly consists of 15 factors. These factors include:

• Well capacity: number of wells required.
• Operational flexibility: well intervention.
• Water depth limits: field specific water depth.
• Deckload capacity: deck weight to be supported.
• Wave resistance: field specific storm and fatigue environment.
• Ice resistance: field specific ice load environment.
• Earthquake resistance: field specific earthquake environment.
• Boat impact risk: field specific boat risk.
• Robustness: reserve strength capacity and damage tolerance.
• Workforce confidence: evaluation of willingness of workforce to accept concept.
• Installation flexibility: competition assessment for installation.
• Reusability: requirement to reduce abandonment costs and capture future value.
• Ease of construction: suitability to local fabrication or out of region fabrication.
• Track record: project view of technology risk based on track record.
• Cost effectiveness: project view of life cycle cost effectiveness.

Production Packer :

A production packer is a standard component of the completion hardware of oil or gas wells used to provide a seal between the outside of the production tubing and the inside of the casing.
