Porthos tenders for subsea CCS pipeline installation
Porthos Offshore Transport and Storage CV has tendered for installation of 20 km of offshore pipeline for its Port of Rotterdam CO2 Transport Hub and Offshore Storage (Porthos) carbon capture and sequestration (CCS) project. The pipeline will move CO2 from Rotterdam to an offshore platform for storage in 3,000-4,000 m below the seabed in the depleted P18-2 North Sea natural gas field.
Scope of work includes dredging work in the nearshore zone and in the Maasgeul channel, execution of shore crossing by pipepull through a preinstalled high-density polyethylene carrier pipe, and installation of 20 km of 16-in. OD pipeline with multilayer polypropylene anticorrosion coating, thermal insulation, and concrete weight coating. Work will also include backfilling the dredged sections of pipeline, post-lay trenching and backfilling of the non-dredged pipeline sections, and precommissioning.
Tenders are due Apr. 18, 2022. The contract would start Jan. 1, 2023, and end Dec. 31, 2026.
Porthos final investment decision is expected in 2022. The greater development will include a 30-km, 42-in. OD onshore pipeline through the port to be built by Denys NV (OGJ Online, Dec. 6, 2021).
