Japanese Patent JP2001507654
Kind Code:
A
Abstract:
The present invention relates to a hull construction for a vessel, especially a drilling and/or production vessel for hydrocarbons. The invention also relates to the application of the hull construction according to the invention.The invention is especially related to designing hulls for single hull ships which are provided for carrying our operations at sea, and especially vessels which are used for drilling petroleum wells, and for intervention and maintenance of this type of well. With the invention, the aim is to provide a hull shape for a vessel which makes the vessel especially well suited for realising these types of well operations in deeper waters and at sea, and so that the vessel can be operative even under difficult weather conditions which are created by waves, ocean currents and winds. The hull design according to the invention will also be well suited for ships which are employed for other current purposes where it is important to control movements of the ship in waves, by way of example in production ships for hydrocarbons, and in ships which carry out seismic investigations of formations beneath the sea bottom.Drilling after oil and gas at sea is carried out either with floating drilling vessels or devices fastened to the bottom The known floating types of vessel can either be half submergible drilling rigs, which are also called "semisubs', or can comprise drilling ships for this type of operation.
