Piping penetration types

When Plant Modeller is integrated with CADMATIC Hull or a third-party hull design tool, you can use the tools in the Penetration group of the Piping tab to add penetration materials to pipes that go through hull plates. The insert tool automatically finds the location where the picked pipe intersects plates that are part of the hull structure of the ship. Then, at each intersection you can select what kind of penetration (if any) is to be created. After placing the penetration parts, the tool creates a hole request so that the hull designer would make a hole in the plate.

Penetrations are inserted according to routing direction, starting from the beginning of the pipe; the picked part does not influence this order.

The supported penetration types are listed below.

• Piping penetration types
• Hole in plate
• Double bushing
• Single bushing and single bushing no cut
• Bulkhead piece
• Bulkhead piece flanged/butt welded
• Bulkhead piece flanged/flanged
• Penetration flange
• Hole reinforcement bushing

Hole in plate

Pipe penetrates the plate through a hole. In the Place Penetrations tool, this hole type allows selecting whether to take insulation into account when computing the required hole diameter.

Double bushing

Pipe goes through the plate and is cut at the exit face. Two inner bushings are added as pipe parts at the ends of the cut pipe. One outer bushing is added as a standard component between the inner bushings.

Single bushing and single bushing no cut

Pipe is cut at the reference face so that it does not go through the plate. One single bushing component is added as a standard component into line. If component is added as onto line part, the cut is not made.

Bulkhead piece

A bulkhead penetration piece is added as a standard component.

Bulkhead piece flanged/butt welded

Bulkhead penetrations where one end is connected with a flange and the other end is butt welded.

Bulkhead piece flanged/flanged

Bulkhead penetration where both ends are flange connections.

Penetration flange

Pipe is cut and flanges are added at the ends of the cut pipe. A penetration flange is added as a standard component between the flanges.

Hole reinforcement bushing

Works as single bushing with no cut. This penetration type can be used for non-watertight penetrations.
