4. Previous Work
Previous work was to define the Scope and Table of Contents of the RP
Receive comments and suggestions from group members

5. Scope:
This Recommended Practice (RP) provides guidance for the performance, qualification, application, quality control, handling, and storage requirements of wet and dry thermal insulation for subsea applications in the petroleum and gas industries. This guideline also covers the inspection of the insulation, and the repair of insulation defects. The installation method is not defined and may be either S-lay, J-lay or Reel-lay. This guideline is intended to cover all three installation methods.
Annex A defines the following:
Minimum requirements for the manufacture and supply of wet insulation (insulations in direct contact with sea water) .
Annex B defines the following:
Minimum requirements for the manufacture and supply of Dry insulation ( applied on Pipe in Pipe systems)

6. This Recommended Practice is applicable to the following:
Applicability of RP 17U
This Recommended Practice is applicable to the following:
Flowlines and Risers
Christmas tree, valve block and piping
Manifold valves and pipework
Pipeline End Termination (PLET) piping
Jumpers (i.e. piping and bends)
Connectors and fittings
Valves and chokes

10. Current Work
Incorporating input from fabricators of wet and dry insulation as well as installation contractors in order to define the general requirements to be incorporated in the recommended practice.
Based on May 2012 group meeting, updates to the draft are being incorporated (as presented on TOC)
Including API formatting guidelines a Draft of the recommended practice should be available on the next session of SC17.
