Testing and Validation

• Validation Testing: Outline how the manufacturer should validate that the equipment or system meets each aspect of the criteria. Specify the test methods, procedures, and acceptance thresholds.

Documented Agreement

• Formal Agreement: It’s crucial to formalize the acceptance criteria and specifications in a written agreement or contract with the manufacturer. This document serves as a reference point throughout the FAT process.

In summary, the establishment of acceptance criteria and specifications is a foundational step in the FAT process. It is a collaborative effort that requires clear, specific, and quantifiable criteria to ensure that the equipment or system meets your operational needs and industry standards.

A Quality Control Plan (QCP) serves as the guiding document that outlines the systematic approach to conducting Factory Acceptance Tests (FAT). It provides a structured framework for ensuring that the equipment or system meets the predefined acceptance criteria and specifications. A well-crafted QCP includes the following critical elements:

Test Procedures and Protocols

• Detailed Test Procedures: The QCP should contain detailed descriptions of each test and inspection procedure. These procedures should be clear, step-by-step instructions that leave no room for ambiguity.
• Testing Protocols: Specify the protocols for conducting each test, including the necessary equipment, parameters to measure, data to collect, and the expected outcomes.

Roles and Responsibilities

• Clear Role Definitions: Define the roles and responsibilities of all parties involved in the FAT process, including asset owners, manufacturers, third-party inspectors, and technicians.
• Responsibility Matrix: Create a responsibility matrix that clearly identifies who is responsible for each aspect of FAT.

Documentation Requirements

• Comprehensive Documentation: Specify the documentation requirements for each test and inspection, including the format for test reports, inspection records, and any corrective action reports.
• Traceability: Ensure that the documentation allows for traceability of test results back to the specific acceptance criteria.

Standards and Best Practices

• Incorporation of Standards: Explicitly state the international standards, industry-specific standards, and best practices that will be followed throughout the FAT process.

Testing Sequence and Schedule

• Sequence of Tests: Define the sequence in which tests will be conducted, taking into account any dependencies between tests.
• Testing Schedule: Create a testing schedule that outlines when each test will be performed. Timely execution of tests is crucial for meeting project deadlines.

Corrective Actions

• Corrective Action Plan: Define the procedures for addressing and rectifying any issues or non-conformities identified during FAT, including timelines and responsible parties.

In summary, a Quality Control Plan is the cornerstone of a successful FAT. It provides a structured framework for conducting tests, defines roles and responsibilities, ensures documentation compliance, and aligns the testing process with industry standards and best practices.

In many instances, asset owners opt to involve a third-party or owner’s engineer to provide an unbiased assessment of the FAT process. Their role is to impartially evaluate adherence to the quality control plan, international standards, and best practices.

Negotiating FAT aspects with the factory is a pivotal step in the preparation and execution of Factory Acceptance Tests. This phase involves collaborative discussions and agreements between asset owners and manufacturers to establish clear guidelines for testing procedures, documentation, and quality assurance.

Testing Procedures

• Collaborative Approach: Begin negotiations by engaging in a collaborative approach with the factory. Encourage open communication and mutual understanding of the goals and objectives of the FAT process.
• Define Test Scope: Clearly define the scope of testing procedures. Identify which tests will be conducted, their purpose, and the expected outcomes.
• Customization vs. Standards: Discuss whether any testing procedures need customization to suit your specific requirements while ensuring alignment with industry standards.

Documentation Requirements

• Document Format: Negotiate the format of documentation, including test reports, inspection records, and any corrective action reports.
