Bay of Biscay: New geophysical and geotechnical studies
electricity transmission network, RTE will carry out new studies at sea
and on land for the proposed link between France and Spain, Bay
The new geophysical and geotechnical studies aim to explore technical solutions
for bypassing the Capbreton canyon.
Previously, studies identified a major technological challenge in the crossing
at sea of the Gouf (canyon) of Capbreton, an unpredictable instability
of the ground, at the edge of the canyon.
Studies will be conducted
in the north and south of the Capbreton canyon (Landes), and in the Médoc,
at Le Porge (Gironde).
In the Capbreton sea
area, two soundings will be carried out by a 56-metre-long platform, about
700 metres away from the beach. These operations will be carried out during
the last two weeks of September. Prior to the arrival of the platform,
two ships will work further offshore for one to two days in September.
On land, geophysical surveys will be conducted during the first two weeks
of September, followed by surveys in the first two weeks of October.
In the town of Le Porge,
surveys and sounding will be done at the landing points of submarine cables,
in the third week of September. A platform similar to Capbreton will be
installed at La Cantine.
The 2GW Bay
has been listed in both the current TYNDP list and Projects of common interest
(PCI) list. The
is expected to double electricity exchange between the two countries and
is scheduled to commission in 2027.
