Frederik
Johan Jonkman was born in Amsterdam on January 31, 1927. Knighted by Queen
Beatrix for his lifetime of service to the marine industry, Jonkman
designed the dry transport system employing submersible barges. During his
career with Wijsmuller Ocean Towage and Salvage Company, he rose to
Managing Director. As owner and President, he founded I.T.C. Holland Heavy
Lift in 1973. Under Jonkman's leadership, the world's first dry transport
of a totally constructed jackup rig on a submersible barge was engineered
and towed by an ocean tug from Ravenna to Dar es Salaam in 1973. This
revolutionary accomplishment proved to the industry that very large
drilling rigs could be transported in a safe and quick manner.
