1. Section 2.1 Wall Thickness
Second sentence reads “Based on the corrosion allowance the pipeline will achieve the design life of (HOLD). LPB confirms design life of 25 years
A. Wojcikowski
(20.06.2016)
Noted and amended accordingly
2. Section 2.2 Corrosion & Material Selection
First sentence reads “The corrosion allowance for the pipeline is HOLD.” Replace HOLD with following “is 3.78mm, so taking into account 0.1mm per year, we have 37.8 years design corrosion allowance.”
A. Wojcikowski
(20.06.2016)
Noted and amended accordingly
3. Section 2.2 Corrosion & Material Selection
Second sentence reads “The material selected is HOLD.” Replace HOLD with following “X-65-C according to API 5LCP.”
A. Wojcikowski
(20.06.2016)
Noted and amended accordingly
4. Section 2.3 Coating & CP
First sentence reads “The coating system is specified by Tenaris as part of the pipeline supply (TBC).” Please reference HDPP coating data sheet for available information. Please note that the HDPP coating is referenced as “Moplen Coat EP/60 BIANCO on page 2 of data sheet.”
M. Maciejewski
(21.06.2016)
Noted and amended referencing HDPP data sheet accordingly
5. Section 2.3 Coating & CP
Fourth sentence HOLD point to be replaced with following “anodes will be installed at the gas export riser wet end.”
A. Wojcikowski
(20.06.2016)
Noted and amended accordingly
6. Section 2.7 Tie-in Design
Remove HOLD point in point 2.7, as LPB confirmed won’t have any Tie-in points along route

1.0 INTRODUCTION
1.1 General
Lotos Petro-Baltic are planning an offshore gas pipeline which will connect a production platform located on the B8 field to a combined heat and power plant (CHP) situated onshore in Wladyslawowo. Prior to being transported in the pipeline the natural gas will be separated from the crude on the production platform. The platform is located in the Poland exclusive economic zone (EEZ) in the Baltic Sea. The B8 field spans an area of 387.1sqare km which was defined in the Concession No. 1/2006 on 5th September 2006 and amended by the Minister for the Environment No. DGiKGe-4770-69/4579/09/MO on 26 October 2009.
1.2 Objective
The objective of this document is to collate the relevant design documentation produced for the pipeline system and provide an executive summary of the system design. This document will not address the design of the flexible riser system.
PIPELINE MECHANICAL DESIGN REPORT

2.0 CONCLUSIONS The summary of the design within the Appendices is described below.
2.1 Wall Thickness
The wall thickness selected for the 114.3mm OD pipeline is 6.35mm. Based on the corrosion allowance the pipeline will achieve the design life of twenty-five (25) years. Details on the calculations used are available within LPB document “Calculation of Pipeline” document number DP00315-OWR, Rev 0, Section 1. Reference Appendix A for extract pages.
2.2 Corrosion and Material Selection
The corrosion allowance for the pipeline is 3.78mm, so taking into account 0.1mm per year, we have 37.8 years’ design corrosion allowance. The material selected is X-65-C according to API 5LCP.
2.3 Coating and CP
The coating system is specified by Tenaris as part of the pipeline supply. Specific details on the coating can be referenced in Appendix C - HDPP Product Detail coating data sheet, Moplen Coat EP/60 BIANCO on page 2 of data sheet for more information The coating thickness is 5.7mm. Corrosion protection in the form of anodes shall not be applied to the pipeline. Corrosion protection at pipeline end shall be by anodes installed at the gas export riser at platform end of pipeline.
2.4 Expansion and Free span
To determine the maximum unsupported length of the pipeline, calculations were performed using AutoPIPE software. Calculations showed that maximum acceptable unsupported length of the pipeline is 50 meters. Details on the calculations used are available within LPB document “Calculation of Pipeline” document number DP00315-OWR, Rev 0, Section 2 & 3. Reference Appendix D for extract pages.

2.5 On-bottom Stability
The On-bottom Stability of the pipeline shall be with concrete mattresses, with position and number to be used calculated within LPB document “Calculation of Pipeline” document number DP00315-OWR, Rev 0, Section 4 Division of the pipeline sections. Reference Appendix E for extract of summary pages.
2.6 Crossing Design
There are no crossings along the route.
2.7 Tie-in Design
There are no Tie-in points along the route.
