• LOT-0001 · Cleaning and gauging (HYRER/HYREL)

  For the pipeline sections 1 to 3 mechanical cleaning using i.e. bi-directional cleaning pigs is considered. Four (4) cleaning pig runs shall be assumed to be required per pipeline section. For the very first cleaning pig run per section a bi-directional pig must be offered which shall proof pig passage by either mechanical or intelligent gauge plate(s).

• LOT-0002 · Mapping (HYRER/HYREL)

  For the pipeline sections 1 to 3 mapping of the pipeline is considered over the entire section or a to be determined sub-section of it. A minimum of twenty (20) AGMs must be provided per section. Inertial measurement data are considered for bending strain analysis which shall be offered as a combined service. For the pipeline sections 1 to 3 the following pipeline anomalies shall be addressed by ILI technologies:

• LOT-0003 · Internal and external metal-loss anomalies (HYRER/HYREL)

  Offered services shall consider internal and external metal-loss detection and sizing in straight pipe, field- and hot-bends. In case a combination of ILI technologies implemented on one or more ILI tools which enable a combined data analysis leading to a superior perfor-mance compared to individual ILI technologies, the technologies shall be offered as a com-bined service and shall be emphasized as such.

• LOT-0004 · Dents, ovalities and roof topping (HYRER/HYREL)

  Offered services shall consider detection and sizing of geometric deviations from the norm of straight pipe and in bends.

• LOT-0005 · Axial cracking and crack-like anomalies (HYRER/HYREL)

  Offered services shall consider detection and sizing of axially oriented crack and crack-like anomalies. The definition of terms is according to the publicly available Pipeline Operators Forum Recommended Practice POF 100 edition 2021.

• LOT-0006 · Pipe material hardness variation (HYRER/HYREL)

  Offered services shall consider detection and sizing of localized variations of the pipe materi-al hardness with respect to the mean material hardness per joint and exceeding an upper and lower bound threshold depending on the offered tool performance.

• LOT-0007 · Pipe material type variation (HYRER/HYREL)

  Offered services shall consider detection of pipe material yield strength variation per joint with respect to available pipe material records per joint.

• LOT-0008 · Axial strain (HYRER/HYREL)

  Offered services shall consider measurement of the axial strain along the entire section lengths. The service shall be offered as a combined service of ILI, strain-based Fitness-For-Service assessment and, if possible, a total strain assessment including bending strain as-sessment results (see Lot 2). Pipe samples and pipe sample data can be provided upfront if needed to enhance the offered performance.

• LOT-0009 · Cleaning and gauging (HYRER Loop)

  For pipeline section 4 mechanical cleaning using i.e. bi-directional cleaning pigs is consid-ered. Four (4) cleaning pig runs shall be assumed to be required per pipeline section. For the very first cleaning pig run per section a bi-directional pig must be offered which shall proof pig passage by either mechanical or intelligent gauge plate(s).

• LOT-0010 · Mapping (HYRER Loop)

  For pipeline section 4 mapping the pipeline is considered over the entire section or a to be determined sub-section of it. A minimum of twenty (20) AGMs must be provided. Inertial measurement data are considered for bending strain analysis which shall be offered as a combined service.

• LOT-0011 · Internal and external metal-loss anomalies (HYRER Loop)

  Offered services shall consider internal and external metal-loss detection and sizing in straight pipe, field- and hot-bends. In case a combination of ILI technologies implemented on one or more ILI tools which enable a combined data analysis leading to a superior perfor-mance compared to individual ILI technologies, the technologies shall be offered as a com-bined service and shall be emphasized as such.

• LOT-0012 · Dents, ovalities and roof topping (HYRER Loop)

  Offered services shall consider detection and sizing of geometric deviations from the norm of straight pipe and in bends.

• LOT-0013 · Axial cracking and crack-like anomalies (HYRER Loop)

  Offered services shall consider detection and sizing of axially oriented crack and crack-like anomalies. The definition of terms is according to the publicly available Pipeline Operators Forum Recommended Practice POF 100 edition 2021.

• LOT-0014 · Pipe material hardness variation (HYRER Loop)

  Offered services shall consider detection and sizing of localized variations of the pipe materi-al hardness with respect to the mean material hardness per joint and exceeding an upper and lower bound threshold depending on the offered tool performance.

• LOT-0015 · Pipe material type variation (HYRER Loop)

  Offered services shall consider detection of pipe material yield strength variation per joint with respect to available pipe material records per joint.

• LOT-0016 · Axial strain (HYRER Loop)

  Offered services shall consider measurement of the axial strain along the entire section lengths. The service shall be offered as a combined service of ILI, strain-based Fitness-For-Service assessment and, if possible, a total strain assessment including bending strain as-sessment results (see Lot 10). Pipe samples and pipe sample data can be provided upfront if needed to enhance the offered performance.
