For manufacturers supplying pressure equipment to European markets, compliance preparation should begin early in the project. Waiting until fabrication is complete can make missing records, unclear responsibilities and documentation gaps harder to resolve.

Pressure vessels, boilers and pressure piping can require different assessment approaches. Establishing the applicable requirements at the start helps manufacturers plan their technical documentation and assessment activities.

Clarify the Equipment and Its Intended Use

Start with a clear description of the equipment, its intended service, materials and design conditions. Drawings and operating information provide the foundation for reviewing the applicable compliance route.

PED and SPVD should not be treated as interchangeable requirements. Their applicability needs to be established for the particular equipment.

Organize the Technical Documentation

Depending on the equipment and assessment route, the documentation may include:

• Design drawings and supporting calculations.

• Material certificates and traceability records.

• Welding procedures and qualification records.

• Inspection plans, NDT reports and test records.

• Operating instructions and other required technical information.

The final document requirements should be agreed for the specific project.

Review Readiness Before Assessment

A gap assessment helps identify missing documents, inconsistent equipment details and incomplete manufacturing records before formal assessment activities.

For example, material identification on a drawing should align with the relevant production and inspection records. Resolving inconsistencies early helps reduce avoidable clarification cycles.

Define Responsibilities Clearly

Manufacturers should understand their own responsibilities and the role of any authorized assessment organization involved. Technical consultancy can support preparation and coordination, while assessment and certification decisions remain with the applicable authorized organization.

MWS supports manufacturers through documentation reviews, readiness assessments and coordination with appropriately authorized partners.
