Routes we have engineered and maintain
Fernando Sanchez
Founder & Chief Executive Officer
Fernando Sanchez started offshore, running survey and installation campaigns across the Atlantic and West Africa before moving into route engineering and full project delivery. Two decades between the deck and the design office convinced him the industry needed a contractor able to own an entire system lifecycle — study, permitting, lay, protection, monitoring and repair.
He founded Greendreams in Los Angeles in 2009 with a small survey team and one standard: nothing goes in the water that the engineering has not fully justified. That principle shaped our burial methodology, our reef-sensitive landfall practice and our insistence on in-house 24/7 monitoring.
Today he leads delivery across seven regions and still personally chairs the technical review for every deep-water campaign the company undertakes.
"The cable is the easy part. Understanding the seabed you are asking it to survive on for twenty-five years — that is the engineering."Read our full story
A cable fault does not wait for office hours
Our marine operations desk is staffed 24/7, with vessels mobilised inside 24 hours of fault confirmation.
