Maritime Reporter spoke with Er- win Lammertink, the CEO of Van Es

Holding BV (the Netherlands parent of Jack-Up Barge, Swift Drilling and other providers of offshore construc- tion equipment) about the feasibility of converting existing rigs into installation vessels for the installations of the ever growing towers, turbines and blades. Its self-elevating jack-up installation ves- sels, working extensively in the North ton lift capability, the ability to handle “One of the great myths propagated has

The European experience is important, but it is only a starting point. A represen- tative from Windserve (a unit of Rein- auer Transportation that is building two

CTVs for work offshore North Carolina and New England, and is tendering for other deals), during a recent presenta- tion in New Orleans, opined that, “Be- cause of the Jones Act, we will see some ingenuity and some new approaches.”

U.S. Jones Act suitable arrangements are already here. A.K. Suda, who has developed con? gurations for ABS detyens.com classed high-spec lift boats deployed drydock@detyens.com across multiple oil basins, has reworked its designs for the offshore wind sector.
