Mr. Herrador has explained that “Semco Maritime is a company with which we fully share our strategic
vision and purpose. Regarding the promotion of the energy transition, the decarbonization of society,
and Europe’s energy independence, thanks to this alliance, we will grow together in the offshore wind
market, gaining weight in the offshore substation segment, leveraging the synergies that both
companies have in this market and the complementarity of our capabilities, knowledge, and corporate
cultures.” He added that “Partnerships have been part of Navantia Seanergies strategy, and pointing as
an example to the relationship with Windar Renovables for foundations for offshore wind turbines.”
Thomas Thomsen stated that “this partnership marks a significant milestone for Semco Maritime as we
continue to expand our footprint in the offshore wind sector. By combining our extensive experience in
HVAC offshore substations with Navantia Seanergies’ industrial capabilities, we are poised to deliver
innovative and sustainable solutions that meet the growing demand for clean energy.
This new partnership will focus on projects in Europe and North America, complementing our existing
collaboration with Vietnam’s PTSC M&C, which also includes the APAC market. We highly value our
