Hybrid Ship Using Wind-Powered Propulsive Force as Auxiliary

Abstract

A hybrid ship which supplementally uses a wind-powered propulsive force in addition to a main engine and a propulsion device driven by the main engine, includes: a tower which includes an accommodation area provided at a stern section and a bridge served as a navigating and maneuvering workstation and provided above the accommodation area, wherein a sail, which is retractable to be stored in each side wall of the accommodation area and which is laterally deployable, is disposed in an airspace, which is located lateral to the accommodation area in the tower, below a height position of a floor surface of the bridge and above a deck.

1 . A hybrid ship which supplementally uses a wind-powered propulsive force in addition to a main engine and a propulsion device driven by the main engine, comprising:
 a tower which includes an accommodation area provided at a stern section and a bridge served as a navigating and maneuvering workstation and provided above the accommodation area, wherein a sail, which is retractable to be stored in a side wall of the accommodation area and which is laterally deployable, is disposed in an airspace, which is located lateral to the accommodation area in the tower, below a window of the bridge and above an upper deck.   
     
     
         2 . The hybrid ship according to  claim 1 , further comprising a bridge wing, which is connected to the bridge served as the navigating and maneuvering workstation disposed above the accommodation area of the tower and which is extended to each of both ship sides, wherein the sail is hung down from a yard to be laterally sail deployable to each of both ship side directions in a lower portion of an overhanging portion of the bridge wing, or below the overhanging portion of the bridge wing. 
     
     
         3 . The hybrid ship according to  claim 1  or  2 , wherein the deployable sail is made of a flexible material, retractable to be stored in a storage portion disposed inside the tower, and deployable to each ship side direction. 
     
     
         4 . The hybrid ship according to  claim 3 ,
 wherein the sail is deployed with a suspension tool suspended by the yard at an upper end of the sail, and with a support supported by a boom at a lower end of the sail, and   as units for deploying the sail,   the yard hanging the flexible sail with the suspension tool and the boom supporting the sail with the support are provided with the suspension tool and the support which are slidably disposed on guide rails provided on the yard and the boom, respectively,   a towing mechanism including a driving mechanism is provided to deploy and retract the suspension tool on the guide rail to and from the ship side direction,   the towing mechanism includes a controller for operating the towing mechanism, and   a lateral sail deploying and retracting power unit is provided for deploying and retracting the flexible sail in a curtain moving manner.   
     
     
         5 . The hybrid ship according to  claim 4 ,
 wherein a framework structure of the tower includes   a main center pillar which is set up at a center of the accommodation area and   auxiliary pillars which are set up at four corners forming a quadrilateral around the main center pillar, and   the five pillars are connected at a top site and a bottom site of the tower with main ribs so that at each of the top site and the bottom site, the main ribs form a cross shape on a horizontal plane and the four auxiliary pillars are connected to each other with auxiliary ribs to form the quadrilateral.   
     
     
         6 . The hybrid ship according to  claim 4 ,
 wherein a framework structure of the tower includes   a main center pillar which is set up at a center of the accommodation area and   auxiliary pillars which are set up at four corners forming a quadrilateral around the main center pillar, and   the five pillars are connected at a top site, a bottom site, and at least one intermediate site of the tower with main ribs so that at each of the top site, the bottom site and the intermediate site, the main ribs form a cross shape on a horizontal plane and the four auxiliary pillars are connected to each other with auxiliary ribs to form the quadrilateral.   
     
     
         7 . The hybrid ship according to  claim 4 ,
 wherein the sail is set as a main sail, and an additional sail yard and an additional sail boom are further extended, from the yard supporting the main sail from above and the boom supporting the main sail from below in a main sail mechanism, to an outside direction of the ship side so that an additional sail is laterally sail deployable.   
     
     
         8 . The hybrid ship according to  claim 1 , wherein the tower is built including the accommodation area such that in a structure of the accommodation area, a height from a deck to a floor of the bridge ranges from 50% to 55% of a ship width. 
     
     
         9 . The hybrid ship according to  claim 5 , wherein the yard and the boom for the main sail are supported to be horizontally swingable by each of the auxiliary pillars near a bow. 
     
     
         10 . The hybrid ship according to  claim 9 , wherein the yard and the boom for the main sail are enabled to turn at a swing angle range of horizontal swinging is 70° to 80° backward from the ship side direction. 
     
     
         11 . The hybrid ship according to  claim 7 , wherein the yard for the main sail is disposed below a bridge wing in each of both sides to hang down the main sail at an upper end of the main sail and the boom for the main sail is disposed on the upper deck to support the main sail at a lower end of the main sail.
