INTRODUCING ATHELEON
ATHELEON was launched to bundle all our offshore wind logistics solutions and engineering, jack-up expertise and special purpose offshore vessels for the renewables industry in one dedicated organization.
ATHELEON is a subsidiary of the Harren & Partner organization and a sister company of SAL Heavy Lift, Combi Lift and SAL Engineering, names that you probably know well as heavy lift marine transportation, offshore engineering and logistics providers. To serve our clients even better, we are combining the abundant expertise in various parts of our group into one specialized unit.
With the purchase of the jack-up vessel Wind Lift I and our partnerships with the Germany-based Off-Shore Wind Solutions and Wind Multiplikator, and a strategic partnership with ONP Management, we have set the starting point for further expansion in the renewables industry.
