When refitting and restoring furnaces, this usually also means restoring the boiler protection. The Pressure Vessel Inspectorate offers the following support:

• Use the form to report the pending change.
• If a burner inspection is required, a technical expert will coordinate the next steps with you at short notice.
• If no burner inspection is required (e.g. if an inspected type of construction is used), we register the change in our file and notify you.
• If you also plan to repair the boiler protection, let our technical expert advise you.

Modernising complete plants will present you with a few challenges:

• if only some of the pressure equipment is replaced, a few units will comply with the new PED (Pressure Equipment Directive) and others will comply with the old SVTI rules.
• Even if components with a CE mark have been added to a plant, no conformity assessments can be performed on the plant as a whole. When putting together the new assembly, the operator could in some cases become the distributor. In accordance with UVG, the operator shall bear responsibility for the older components and the plant as a whole.

That means: Plant operators must grapple with the topic of placing the plant on the market both safely and in compliance with the regulations at a very early stage. The Support team will assist you by

• defining the assemblies
• connecting the assemblies to plant parts that have proven themselves in operation, complete plants and Los-HAZOP
• performing final testing, inspecting documentation about the assembly prior to placement into service
• inspecting safety equipment
• registering the new pressure equipment with SUVA and drawing up inspection manuals
• project support for "compliant initial market placement"

Will the safety equipment on your plant still comply with valid rules if you exchange or replace parts of it? You are best off having the safety equipment inspected and modifications made immediately whenever you purchase any replacement part. The Pressure Vessel Inspectorate will assist you by

• taking stock of existing safety equipment
• performing design reviews of changes
• performing a final evaluation (evaluation of the assembly prior to placement into service)
• inspecting the safety equipment
• performing individual burner acceptance in accordance with EN12952 or EN12953 and TRD (Technical Rules for Steam Boilers) 

The Ordinance on the Utilisation of Pressure Equipment (Druckgeräteverwendungsverordnung) from 2007 stipulates that the operator is responsible for the safe, compliant placement into service of pressure equipment.

Correct construction of a piece of equipment or assembly is generally confirmed by the manufacturer by means of a declaration of conformity (for an assembly). It does not apply, however, if the assembly is connected to an existing plant. While initial market placement of the pressure equipment or assembly was compliant, this does not automatically mean that the safe equipment requirements have been fulfilled in accordance with UVG (Swiss Federal Law on Accident Insurance) or VuV (Ordinance on Accident Prevention). In order to ensure that you provide your staff with safe equipment, the Support team offers the following services for plant operators:

• risk analysis via HAZOP (Hazard & Operability Study)
• inspection of safety equipment
• risk assessment in accordance with TRBS (Technical Rules for Occupational Safety)
