API 17G3 – LIGHT DUTY INTERVENTION SYSTEM
WINTER MEETING STATUS REPORT
4.
MAJOR ISSUES
API 17G3 is different from G2 (subsea pumping) and G4 (riserless intervention) in
that it is a pipe based system. Deviation from API 17G, for a pipe based system,
should only come in the form of reduced application if API 17G functionality is
removed for simplification.
The challenge 17G3 is facing is the volume of applications and configurations one
could dream up for a Light Duty Intervention System. Light Duty Intervention
System, by name, is light. It is a pipe based system designed with reduced
functionality for a specific use or application. The whole of API 17G may not apply
to LDIS, but there are minimum 17G requirements that must be followed.
A design flow chart was proposed as a way to guide designers, manufactures and
operators to a set of minimum requirements when specifying a LDIS. After thinking
about this further, a design flow chart is nothing more than an applied safety strategy
which the current 17G requires.
This direction was proposed to API 17G members during the August, 2014 meeting
in Galveston. It was unanimously accepted.
API 17G3 should document an example, common application, such as executing a
through-tubing intervention with wireline only by using the 17G safety strategy in the
form of a design flow chart. The method can then be applied to any application or
system configuration.

PLANS FOR FUTURE MEETINGS
Review the design flow chart method for specifying LDIS for a specific application
and determine if this direction is useful for the industry.
7.
RESOURCE NEEDS
Participation has dropped off. Resources from manufactures and end users are
needed to mature the example design flow chart and bring this effort to an end.
