Training Information

  • Schedule:

    It is intended that the JIP will start during the first quarter of 2017 and have a duration of three years.

Technology Qualification using DNV-RP-A203 is proposed to improve practice, and thereby reducing cost related to mechanical connector application in deep-water developments. Results of the JIP shall be used for the development of a guideline document for connected pipeline systems.

  • Reduced offshore installation time
  • Installation with smaller installation vessels
  • Standardize connected pipeline systems
  • On-shore pre-fabricated joints for better project control
  • Increased fatigue resistant joints
  • Recoverable, re-usable and repairable systems
  • Simplified installation for large diameter clad lined and non-clad pipelines

Project Attributes:
  • Evaluate multiple supplier/ manufacturing technologies, generate Qualification Basis and prepare Supplier Technology Status Report
  • Conduct Technology Qualification program
  • JIP Final Deliverable: Connected Pipeline Guideline

Value Delivered:
  • Reduce CAPEX expenditure with lower contract lead times, faster installation and the possibility for utilizing locally sourced contractors with smaller installation vessels
  • Evaluate multiple supplier  technologies and their status for deep water development needs
  • Faster Project schedule with standardized  on-shore pre-fabricated joints
  • Increase feasibility of large export line projects with simplified installation of large diameter pipelines; feasibility of deep-water projects with faster installation while maximizing the available weather window

JIP Road Map


Overall Scope: Phase I may be treated as a design competition where suppliers are invited to participate
  • Workshops- connector suppliers/ manufacturers, EPCI firms and operators
  • Provide status, history, application data & any existing qualification data/ FMECA (suppliers/ manufacturers)
  • Determine preliminary criteria for evaluation (DNV GL with operators and EPCI firms)
  • Develop & issue Qualification Basis (DNV GL with operator approval)
  • Invite suppliers to submit Design and documentation supporting the Qualification Basis
  • DNV GL to perform screening study & develop Supplier Technology Status Report

  • Qualification Basis (for all participants)
  • Supplier Technology Status Report (to operators/ EPCI & respective Suppliers only)
  • Selected Supplier for JIP Phase II (based on operator Steering Committee input)

- $35,000 USD per operator
- $15,000 USD per supplier/ manufacturers/ EPCI firm

Minimum 3 operators & 4 Suppliers considered

Subsequent Phases

Phase II
Activity according to TQ Plan developed in Phase I for selected suppliers

Phase III

Update acceptance criteria- design through installation; Develop JIP deliverable- Connected Pipeline Guideline
