Recursos de Squeeze Off do UPDM

EdwardBlair

Oi -

O modelo UPDM parece representar eventos de squeeze-off como recursos em uma classe não relacionada à rede (fora da rede de utilidade). Nosso dado atual tem squeeze-offs como recursos simples de junção -- então esses locais podem ser identificados por um traçado.

Vamos perder funcionalidade se migrarmos nossos squeeze-offs atuais para a classe P_SqueezeOff do UPDM, que não está na rede?

Obrigado,

Hi Ed,

In addition to Robert and Ayan's great comments, I do have one more for you. A P_SqueezeOff feature's purpose is to denote where the pipe has previously been subjected to the material stress of a clamp to "squeeze off" the flow of gas. The importance of this is to insure that a pipe is not squeezed more than once at a single location. If you are interested here is a document from Performance Pipe on best practice for polyethylene pipe squeeze-off.  The document specifies multiple constraints on where a squeeze can be applied. One of which is the location of a previous squeeze off. As such, it should never be used as a barrier feature in an isolation trace, as that would likely lead to field techs applying a 2nd squeeze off at a location where one should not occur. Managing the P_SqueezeOff data as a simple point feature outside of the Utility Network, accomplishes its purpose which is to convey the location where a field technician should not apply a squeeze off.
