Design, Maintenance and Inspection of Storage Tanks

Designed for

All staff like Engineers, Operators, Technologists, in-volved in design, maintenance, modifications and Inspection of storage tanks.

Purpose

To give the

• A proper understanding of the different types and design of Storage tanks and tank farms.
• Knowledge on the failure mechanisms and based on that the optimum maintenance and Inspection activities based on Risk management.
• A proper understanding of the operational aspects of storage tanks.

Objectives

• By the end of the course, the participants will be able to:
• Explain the functions of structural parts of storage tanks and tank farms and fittings to conventional storage tanks,
• Explain design and operational aspects of storage tanks
• Set up inspection and maintenance pro-grammes/schedules, based on known failure mechanisms and Risk Management.
• Choose between the different maintenance me-thods (condition/repair), and verify changes to Storage tanks regarding Integrity.

Subjects

• Types of conventional storage tanks.
  Fixed and floating roof tanks, tank selection re product classification, including cost awareness for new structures.

• Design aspects.
  Design codes and company standards, venting requirements, special design, relevant fixed and floating roof specific components, tank shell design and tank foundations.
• Operational Aspects.
  Blending, tank mixers, operational windows (such as pump rates, product temperature, pressure, TVP/RVP, etc), floating roof movements, roof drains and roof seals.
  Emission calculations for fixed and floating roof tanks.

• Tank maintenance, Inspection and Engineering.
  Storage tank inspection procedure, record system, on and off-stream inspections, assessment of the inspection finding against the relevant codes/criteria and the translation into a cost-effective maintenance scope.
  Introduction in Risk Management. ( RBI and RCM) to optimize Integrity and Reliability.

• Maintenance activities.
  Common maintenance work and methods re tank structure, tank fittings and tank foundation, new and maintenance coating, including tank jacking based on international and company standards (API/EEMUA/), Scaffolding.

• Safety aspects.
  Fire Safety requirements, maintenance of firefighting equipment, International safety codes (NFPA/IP), layout considerations, tank entrance (permits).

• Pressurized Storage (spheres, mounded and bullets)
  Design and operation aspects, dominant failure modes, Safety aspects and typical maintenance and inspection strategies.
