We are not a labour supplier. We are an accountable shipbuilding partner.
With over 13 years of experience and a team of more than 200 employees, including 170 direct production workers—welders, fitters, grinders, experienced foremen and site managers—we have established ourselves as a trusted partner in the shipbuilding industry, both nationally and internationally.
Every crew operates under GESO supervision. Every delivery carries our name. If something must be corrected, we own it, resolve it and deliver it to the yard’s standard.
