Energy transition: a growth strategy for SADE.
Background
In 2019, the Boulonnais Local Authority (CAB) carried out a feasibility test for the installation of an ambient loop system using seawater to produce heat. The study site is located in the port of Boulogne-sur-Mer (Capécure area).
The aim of the is to power two warehouses of the cold storage company Norfrigo, in place of the current air-cooled condensers, and thus enhance the energy efficiency of the refrigeration production unit.
The study consists in the creation of two ambient heat loops:
- A seawater loop
- An intermediate industrial water loop (glycol water)
The seawater loop will be regulated at the pumping station in the Loubet Basin. A technical unit will be located at the junction of these two loops. It will contain the various elements required for the smooth execution of the process, including plate heat exchangers at the seawater /glycol water interface.
Works were designed by SIng and carried out in part by the Hauts-de-France RD
The Boulogne-sur-Mer Agency (Hauts-de-France RD) within a consortium, was awarded Order 1 for the creation of the seawater loop. The main works for this operation are:
- The laying of 250m of underground pipelines for the glycol and sea water section (225mm-diameter HDPE)
- The laying of electrical priming pipes, around 100m of optic fibre, and junctions to networks
- Wastewater junctions (125m of 160mm-diameter) from the technical station
Pre-project studies were produced by SIng, with the phasing designed in 3D.
A 3-month project on the road to energy transition!
