FAT & SAT Survey Project
Independent Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) Survey and technical witnessing services for marine, offshore and industrial equipment, supporting verification, installation, testing, findings and reporting before delivery, commissioning or operational handover.
FAT & SAT Survey Project Overview
Factory Acceptance Testing (FAT) is normally performed at the manufacturer, supplier or designated test facility before equipment is delivered or installed. Site Acceptance Testing (SAT) is normally performed after installation at the vessel, shipyard, offshore facility, terminal, plant or other designated project location to verify applicable functionality, interfaces, integration and site-specific requirements.
PAMS provides independent FAT and SAT survey and technical witnessing services for shipowners, operators, managers, purchasers, shipyards, offshore projects and other clients requiring independent observation and documentation of agreed testing activities.
Client Requirement
Clients may require an independent technical representative to attend FAT activities at the manufacturer or designated test facility and SAT activities at the vessel, site, offshore facility, terminal or project location.
Independent Attendance
Independent attendance provides an objective technical presence during agreed FAT and SAT activities, with observations recorded against the applicable project scope and available documentation.
Project Verification
FAT and SAT witnessing supports project verification by documenting witnessed tests, available results, technical observations, deviations and incomplete activities.
FAT & SAT Survey Project Scope
Pre-FAT / Pre-SAT Review
Review of available technical specifications, drawings, procedures, test protocols, equipment documentation and project requirements before FAT and/or SAT attendance.
FAT Witnessing
Independent attendance during agreed Factory Acceptance Test activities at the manufacturer, supplier or designated test facility, with recording of witnessed testing and available results.
SAT Witnessing
Independent attendance during agreed Site Acceptance Test activities following installation, including functional testing, system interfaces, integration checks and applicable commissioning-related verification.
Technical Observations
Recording of observed deficiencies, deviations, incomplete activities, test limitations or other technical matters identified during FAT and SAT activities.
FAT & SAT Reporting
Preparation of an independent survey report documenting attendance, equipment identification, witnessed activities, available test results, observations and recorded findings.
Follow-Up Verification
Where requested, independent attendance during re-testing, corrective-action verification or repeat FAT/SAT activities following resolution of recorded findings.
Independent FAT & SAT Technical Witnessing
PAMS acts as an independent technical observer during agreed FAT and SAT activities. FAT witnessing generally takes place before delivery at a manufacturer, supplier or designated testing facility, while SAT witnessing generally takes place after installation at the intended vessel, site, offshore facility, terminal or project location.
The applicable testing organization, manufacturer, supplier, contractor or commissioning team remains responsible for performing the tests in accordance with the approved procedures and project requirements. PAMS records what is independently witnessed and reports relevant technical observations and findings.

What is a FAT Survey?
A FAT Survey is an independent technical witnessing and reporting activity conducted during agreed Factory Acceptance Testing, normally before equipment is delivered or installed.
What is a SAT Survey?
A SAT Survey is an independent technical witnessing and reporting activity conducted during agreed Site Acceptance Testing, normally after equipment or systems have been installed at the designated vessel, site, offshore facility, terminal or project location.
What is the difference between FAT and SAT?
FAT is generally performed before delivery at the manufacturer or designated test facility, while SAT is generally performed after installation at the intended site or operational location. FAT focuses on equipment verification before delivery, while SAT can include installed functionality, interfaces, integration and site-specific verification.
