Benefits of technology

This technology allows an oily vessel (oil platforms) to be connected by wires without having to go through complicated procedures like connecting them manually. Its technical effect lies in that it provides easy accessibility while avoiding collisions caused by hard obstacles such as rocks or waves during connection process. Additionally, this design prevents damage to ships' structures due to excessive movement around corners where there are sharp bends at certain points along its length.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the functionality and flexibility of fully turn tugs (FRT) boats that can navigate through different directions without being limited by their structure).

Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] like figure 1 , figure 2 As shown, the present invention includes a hull 1, a water diversion bell 2 arranged longitudinally through the center of the bottom of the hull 1, an azimuth propeller 3 located below the stern, a crank arm telescopic crane 4 arranged on the hull cabin, and a hull 1 The towing machine 5 in the middle of the deck and the rope-resistance device 8 at the stern, the hull 1 of the present invention adopts a through-type water diversion bell 2, the stability of the ship is significantly improved, and the azimuth propeller 3 promotes the multi-directional movement or maintenance of the present invention. The position of the ship, the crank arm telescopic crane 4 can play an auxiliary role in the lifting of heavy objects on the ship deck and the dragging of the anchor chain on the platform. The rope resistance device 8 prevents the steel wire rop

Abstract

The invention discloses a full-revolving tugboat with a stern roller. The full-revolving tugboat with the stern roller comprises a boat body, a water distribution hammer, a full-revolving propeller, a crank arm telescopic crane and a towing engine, wherein the water distribution hammer is arranged at the center of the bottom of the boat body and is through longitudinally, the full-revolving propeller is positioned below a stern, the crank arm telescopic crane is arranged on a cabin of the boat body, the towing engine is arranged in the middle of a deck of the boat body, the stern roller is arranged in the middle of the stern, and rope blocking devices are arranged on two sides of the stern. When the full-revolving tugboat tows an oil platform or underwater anchor chain, one end of a steel wire rope on the towing engine is connected with the oil platform or underwater anchor chain under the guide of the stern roller. The stern roller having a guide function is additionally arranged in the middle of the stern, therefore, the structure is simple, the operation is convenient, and the application range of the full-revolving tugboat is enlarged. The stern roller is arranged on the inner side of a rubber fender of the stern, therefore, rigid collision between the stern roller and other objects is avoided, and the rope blocking devices can prevent the steel wire rope from sliding to the stern to damage the boat structure when the boat swerves.
