Germany - Gas pipes

Description

Demand for gas transport capacity in Baden-Württemberg is rising steadily. For this reason, terranets bw is planning the new natural gas transport pipeline "Süddeutsche Erdgasleitung" (SEL).SEL will start near Lampertheim and run south of Heilbronn, north of Ludwigsburg to Esslingen over a total length of 250 km. In Lampertheim, Grenzhof, Kirchhausen and Löchgau, important network junctions to the existing tnbw network will be built. The pipeline is to be constructed in several phases, with delivery dates determined by these phases. This tender includes services for the first two construction phases:Construction phase 1: Heilbronn to Löchgau (24 km, DN 1200) in 2023/24Construction phase 2: Löchgau to Esslingen (44 km, DN 1000) in 2024/25The services for further construction phases will be the subject of future tenders.The subject of the award is the supply of pipe material for underground installation in accordance with terranets bw specification leaflet M 1.100, resp. M 1.110 (draft).In this phase of the procedure no offers resp. prices may be submitted.It is pointed out that there may be deviations in the contents of the leaflets, which are currently still in draft form, until the invitation to tender.The client attaches importance to the greatest possible conformity of the product offered with the order specification. In the interest of future developments, hydrogen compatibility will be given special attention in the awarding of the contract.Technical data on the pipelineNominal diameter of main line SEL 1: DN 1200Minimum wall thickness of main line SEL 1: 23.5 mmNominal diameter of main line SEL 2: DN 1000Minimum wall thickness of main line SEL 2: 19.6 mmDesign pressure: DP 100Pipeline length of construction sections SEL 1: 24 kmPipeline length of construction sections SEL 2: 44 kmTotal line length SEL: Approx. 250 km
