Retendering Framework Agreement on Pigging Services for conduction of inline inspection of natural gas pipelines

Description

Through the establishment of a framework agreement, the Contracting Authority wants to purchase Pigging Services for conducting inline inspection of Buyer’s natural gas pipelines. The Tender is divided into 3 Lots: • Lot 1: Onshore Launch/Receival Service • Lot 2: Alternative Technologies Service • Lot 3: Offshore Launch Service Lot 1: LOT 1: Onshore Launch/Receival Service Through the establishment of the present framework agreement, the Contracting Authority wants to purchase Pigging services for conducting inline inspection of Buyer’s natural gas pipelines. The Provider must perform in-line service comprising a cleaning and gauging survey and a subsequent in-line inspection. The cleaning and gauging survey shall clean and identify any obstructions in the pipeline in advance of the in-line inspection. The in-line inspection shall log the geometry and condition of the pipeline. The in-line in-spection shall be performed by a single combined tool capable of logging both pipe geometry and anomalies (e.g. metal loss). Lot 1 covers the lines specified in Appendix 2A Section 2.1 and the in-line services described in Section 2 – Section 6. Please note that this is a negotiated procedure. With the exception of mandatory parts, the Tender Documents may as a result undergo changes as part of the negotiation process. Lot 2: LOT 2: Alternative Technologies Service Through the establishment of the framework agreement, the Contracting Authority wants to purchase Pigging services for conducting inline inspection of Buyer’s natural gas pipelines. The Provider must perform in-line service comprising a cleaning and gauging survey, and a subsequent in-line inspection. The cleaning and gauging survey shall clean and identify any obstructions in the pipeline in advance of the in-line inspection. The in-line inspection shall log the geometry and condition of the pipeline. The in-line inspection shall be performed by a single combined tool capable of logging both pipe geometry and anomalies (e.g. metal loss). The following applies to the lines specified for lot 2 in Section 2.1 and should be read in conjunction with Section 2 – Section 6 and Section 9 (for specific lines). 1.1 Integrity Inspection Requirement (Reference is made to Section 4.6.2) The scope of this lot targets alternatives to the MFL technology (e.g., UT), which are cable of: • Determine significant corrosion features, with an accuracy < 0.5mm at POD > 90%. • Identifying features within the pipe wall. • Being performed in gas medium to limit the impact on operation during the inspection. • Potentially being a supplement to MFL results, to compose a complete picture of the features if combined with MFL inspection results. Please note that this is a negotiated procedure. With the exception of mandatory parts, the Tender Documents may as a result undergo changes as part of the negotiation process. Lot 3: LOT 3: Offshore Launch Service Through the establishment of the present framework agreement, the Contracting Authority wants to purchase Pigging services for conducting inline inspection of Buyer’s natural gas pipelines. The Provider must perform in-line service comprising a cleaning and gauging survey, and a subsequent in-line inspection. The cleaning and gauging survey shall clean and identify any obstructions in the pipeline in advance of the in-line inspection. The in-line inspection shall log the geometry and condition of the pipeline. The in-line in-spection shall be performed by a single combined tool capable of logging both pipe geome-try and anomalies (e.g. metal loss). The following scope of work solely relates to the offshore pipeline Europipe II – Houstrup (21-241) and associated onshore pipeline section Houstrup – Nybro (23-403) shown in Figure 9 1 and specified in Section 2.1 and should be read in conjunction with Section 2 – Section 6. Please note that this is a negotiated procedure. With the exception of mandatory parts, the Tender Documents may as a result undergo changes as part of the negotiation process.
