Pipeway Elevation

The pipeway-elevation component evaluates pipeline elements on per level per section per pipeway basis. Pipelines are considered on a specific elevation if it is between the upper and lower approach levels of the given berthing level of the pipeway.

On its own, the pipeway-elevation component can be limited; therefore, you are advised that the larger component expression ofpipeway.section.pipeway-elevation be used. For information on the piping supported by each rack level, you will need to add pipeline elements to the report's component expression.

Element	Attributes / Relationships	Name	Definition
`pipeway-elevation (horizontal pipeways)`	attributes	elev	The berthing elevation of pipeway level
		lower-threshold	Elevation of lower approach level of current berthing level
		sequence	The level number counted from bottom to top and restarts with each section
		upper-threshold	Elevation of upper approach level of current berthing level
	relationships	pipeline-element

A Two section horizontal pipeway

Section 1 Elevations:

110 ft (approach)
113 ft (berth)
116 ft (approach)
120 ft 6.0 in (berth)
125 ft (approach)

Section 2 elevations:

110 ft (approach)
113 ft (berth)
116 ft (approach

For this two-section pipeway, the report attribute values are:

		elevation	lower- threshold	sequence	upper-threshol
Section 1:	Level 1	116’	100’	1	133’ 4
	Level 2	133’ 4	133’ 4	2	150
Section 2:	Level 3	150’	150	1	175’ 3
	Level 4	175’ 3	175’ 3	2	201’ 8

Element	Attributes / Relationships	Name	Definition
`pipeway-elevation (vertical pipeways)`	attributes	elev	The elevation of pipeway bents
		lower-threshold	For the bottom bent, the zordinate of the structure section For any other bent, the elevation of the bent.
		sequence	The level number counted from bottom to top and restarting with each section
		upper-threshold	For the top bent, the top of the routing volume of the structure section For any other bent, the elevation of the bent above the current bent.
