Project details

The aim of this project is to supply the CHU Sud de la Réunion in Saint-Pierre with air conditioning produced from sea water pumped from a depth of 1000m in the Indian Ocean. This SWAC (Sea Water Air Conditioning) will not only enable annual savings of 6,900 tonnes of CO 2 over 20 years, but will also demonstrate the relevance of such a system as this project is also a demonstrator. This SWAC, both innovative and sustainable, is a world first in several respects:

  • The first SWAC in the world with marine pipes running under the corals, thus avoiding a trench through the lagoon
  • World’s first SWAC with variable seawater pumping rate
  • World’s most powerful SWAC
  • SWAC with the longest sea pipes to reach 1000m depth

Role Definition

Within our start-up and in interaction with other external actors, you will work in the framework of a seawater air conditioning (or SWAC) project. Your role will be to design two underwater pipelines: one for suction and one for discharge of seawater. The objective is to construct and install these pipelines, therefore experience in installation analysis and offshore field experience on the same or similar issues is required.

More specifically, the role of the assignment will be to:

o Research a configuration :

  • Carry out a comparative study associated with hydrodynamic analyses,
  • Evaluate and compare the impact of each of the configurations found on the other lots of the project (technical and financial),
  • Write a report explaining in a precise and clear manner the problematic, the methodology used as well as the path and the explanations that lead to the selection of the configuration

Route selection

  • Based on bathymetry and meteo ocean data, draft a route selection report.

Preliminary design study.

  • Drafting of a hypothesis log,
  • Carrying out hydrodynamic analyses (in-place, stability, extremes and fatigue),
  • Drafting of an analysis report,
  • Carrying out a detailed description of the configuration (this includes the anchor lines and the type of anchor to be considered),
  • Estimation of the associated costs for the construction of the solution

Installation of the pipelines

  • Analyse the manner in which the two pipelines will be installed at sea,
  • Drafting of an installation methodology note,
  • Estimation of the costs via a consultation of the subcontractors who will carry out the installation.

Manufacture of the pipelines

  • Analyse the manner in which the two pipelines will be manufactured,
  • Draft a note outlining the construction strategy and the logistical strategy to be put in place in order to have the material available on site,
  • Estimate the associated costs.


You have a degree in engineering specialising in offshore hydrodynamics and at least 8 years experience in a similar position. You are familiar with hydrodynamic numerical analysis tools such as Orcaflex or Deeplines. You have experience in hydrodynamic calculations, design of subsea pipelines. You are fluent in English. You have a good team spirit, you are curious and open-minded.

You have the following skills:

  • Excellent verbal skills Excellent writing skills Hydrodynamic skills
  • Knowledge of the main offshore codes (subsea pipelines and offshore installation)
  • Field experience, offshore assignments
  • Analytical skills
  • Organisational skills
  • English (required), another language other than French would be a plus

You wish to have a real impact on the energy transition and act to reduce CO2 emissions.

You are adaptable and responsive. You have a critical and synthetic mind. Your qualities are creativity, proactivity, rigour and curiosity: do not hesitate to contact us to join our team.
