Abstract
The method of providing a latch which is capable of passing a relatively short radius bend in a pipeline and then engaging a fishing neck on a service tool in a pipeline, and after the latch has engaged the service tool having the ability to pass the combination back through the relatively short radius bend in the pipeline.
Claims11
A method of connecting to a service tool in a pipeline comprising:
- having one or more fishing necks on said service tool approximately concentric with said pipeline,
- providing a latch on a fishing tool suitable to engage at least one of said one or more fishing necks,
- holding said latch approximately concentric with said pipeline,
- engaging said latch with one of said one or more fishing necks,
- providing two alignment surfaces spaced apart for maintaining a centerline approximately parallel and concentric to the centerline of said pipeline, and
- at least one of said two alignment surfaces is proximately spherical.

A method of connecting to a service tool in a pipeline comprising:
- having one, or more fishing necks on said service tool approximately concentric with said pipeline,
- providing a latch on a fishing tool suitable to engage at least one of said one or more fishing necks,
- holding said latch approximately concentric with said pipeline,
- engaging said latch with one of said one or more fishing necks,
- providing said latch will automatically release from said one or more fishing neck at a predetermined force, and
- said automatic release at said predetermined force is the result of shearing a shear pin.
