Project overview

Medior Project Manager

For Porthos, we are looking for a driven Medior Project Manager with experience in CC(U)S, oil and gas production environments, or similar, and a background in project management. In this role, you will strengthen the onshore team and support Project Management in the daily direction and control of the project. You will have a broad role where project control, documentation, verification and validation, coordination, and stakeholder management come together within an innovative project that is crucial for reducing CO2 emissions.

About Porthos

Porthos CO2 Transport and Storage C.V. is seeking a Medior Project Manager. Porthos is a project to transport and store CO2 from industry in the port of Rotterdam in empty gas fields under the North Sea. The CO2 transported and stored by Porthos will be captured by various companies. The companies will supply their CO2 to a pipeline running through the Rotterdam port area. The CO2 will then be pressurized in a compressor station, after which the CO2 will be transported via an offshore pipeline to a platform in the North Sea, approximately 20 km offshore.

From this platform, the CO2 will be pumped into an empty gas field. The empty gas fields are located in a sealed reservoir of porous sandstone, more than 3 km below the North Sea. It is expected that the project will be able to store approximately 2.5 million tons of CO2 per year from the second half of 2027.

Within Porthos, we work in multidisciplinary teams from the various parent companies EBN, Port of Rotterdam Authority, and Gasunie.

The Role

Your direct task is to support Project Management. You will assist with daily tasks and responsibilities and ensure that Project Management has the necessary management information. You will do this by managing information flows on various files and working from detailed information to the desired level of information. Regarding project documentation, you will be responsible for drafting, updating, and maintaining documentation related to the various files, including project execution plans, reports and specifications, presentations, and minutes.

One of these files will include the verification and validation of project requirements. In addition, you will use your well-developed functional leadership and coordination skills to bring the right people together and direct them. You will evaluate both your own actions and those of the team to improve efficiency, project structures, and quality, and to ensure that project goals are achieved on time. Through your creative approach, you will motivate the team and contribute to a positive working atmosphere.

You will operate within a complex organization, recognize the interests of various stakeholders, and be able to respond adequately to them. You will take these interests into account in both the preparation and execution of the project.
