Current Forecast for Transport of Semisubmersible Drilling Rig
DHI Water & Environment provides operational current forecast support and general advice of hydrographical conditions during transport of a semisubmersible drilling rig (Stena Don). The rig/barge system is being towed from the yard in Rostock through Øresund until sufficient depth for onward tow to Stavanger of the rig alone is possible.. The most critical operation is the disconnection and separation of the rig and the barge at a location in Øresund offshore Humlebæk/Espergærde.
Operational two-day forecasts of currents at different depths and water levels are based on DHI's operational 3D model of the North Sea, the Baltic Sea and the Danish Waters ( www.waterforecast.com ).
