Model Comparisons
NAESB Nomination Model used in PASSKEY = Pathed (threaded)
–
“Threaded” refers to linking a shipper’s specific commercial counterparties at receipt and delivery
locations to a specific pathed transport nomination line item, and to each other.
–
Ranking are inputted at receipt and delivery ends of path. Ranks are used in applying scheduling cuts (of
within same level of priority), balancing transactions caused by receipt and delivery reductions (both
during confirmations and pipeline balancing) across all of a shippers contracts at a scheduling restriction
or balancing location.
–
Once a path is determined to be cut the linked market (or supply) must be cut. There is no flexibility to
allow shippers to unthread their transactions.
NAESB Nomination Model used in DART= Pathed Non-threaded
–
Allows a shipper to separate commercial counterparty (buy/sell) transactions at specific locations from
transportation transactions between locations.
–
Gives shippers more flexibility of their business via ranks. Shippers can individually rank supplies and
markets, receipt and delivery locations, and paths between receipt and delivery locations. This model
also inherently supports cross-contract ranking for balancing transactions caused by receipt and delivery
reductions (both confirmations and pipeline balancing). Path ranks are used to apply scheduling
restrictions among all the paths within a given contract.
–
Once a path is cut, the shippers ranks dictate which market (or supply) gets cut. There is no linked supply
to market forced cuts.

Example of Pathed Non-threaded (DART)
This activity is pathed because a specific receipt location is tied to a specific
delivery location on each line item.

This activity is not threaded because commercial counterparties at the either end of the path are not specifically
linked to each other. For example: receipt reductions of upstream suppliers is fully in the control of the shipper
via separately identified ranks all the way to the ultimate downstream markets.

Example of Pathed Non-threaded (DART) – with Ranks
Receipt Rank (Downstream Transport
Line Item at Point A); ranking paths
across contracts for cuts coming from
suppliers to delivery paths across
contracts.
Delivery Rank (Upstream Transport Line
Item at each Point B, C, & D); ranking
paths across contracts for cuts coming
from markets to receipt paths across
contracts.
