The offshore wind market in the U.S. is about to take off and there are enormous growth projections. For the installation of the first wave of U.S. wind parks starting in 2020, European built and operated installation jack-ups will be needed, because currently no U.S. built jack-ups have the capacity to install the turbines. Nor will this type of equipment be built in time in the U.S. PES takes a closer look at the options. There are plans to build installation jack-ups in the U.S., but it is likely that these will only kick-off after the first wind farms prove to be a success. Aside from this, the infrastructure of the U.S. ports is not suitable for these big vessels, there are bridges and hurricane breakers preventing the jack-up installation vessels to enter or leave the harbors. New hubs and ports will have to be developed before U.S. flagged installation jack-ups will become a practical tool for the installation of the parks. The problem with using European installation jack-ups, apart from the a fore mentioned infrastructural problems, is the Jones Act. The Jones Act requires vessels transporting merchandise from U.S. point to U.S. point to be U.S. manned, built, flagged and owned.
