RU2802649C1 - Freight vessel for cargo handling at undeveloped beach - Google Patents

Abstract

FIELD: transport.

SUBSTANCE: proposed freight vessel comprises superstructure, helipad at vessel stern behind said superstructure, service platform, through cargo space, fore and aft landing devices. Superstructure is divided into fore and aft superstructures. Pilot house is located at fore superstructure. Through passage and hanger with sliding section are arranged at aft superstructure, hanger communicating service platform with helipad to allow location of equipment at said helipad (in the absence of helicopters). The main power plant represents a two-stage design.

EFFECT: enhanced performances.

Description

The invention relates to the field of shipbuilding equipment, namely to a transport vessel designed for loading, transporting and unloading self-propelled and floating equipment and for basing helicopters on an unequipped shore.

The closest in design is the Chinese landing ship 10 YUTING I (TYPE 0722 II) CLASS (LSTH), which is listed in the IHS Jane's Fighting Ships reference book, 2012-2013, p. 154, which we accepted as a prototype.

The ship has a helipad, a through cargo hold running the entire length of the ship with a bow and stern disembarkation device for loading (unloading) landing equipment, a cargo platform equipped with a standard crane, an engine room made in one compartment, and one aft superstructure.

However, the landing ship chosen as a prototype has a number of disadvantages:

- lack of a hangar for a helicopter, which leads to the fact that the helicopter is located on the upper deck of the ship sporadically without being permanently based on the ship;

- impossibility of using a helipad for placing equipment;

- the main engines are located in one compartment, which impairs the survivability of the ship;

- the aft location of the superstructure impairs visibility from the wheelhouse along the ship's course when approaching the shore.

The purpose of the present invention is to create a ship that eliminates these disadvantages, namely, ensuring the basing of two helicopters on a ship with the possibility of using them in winter, providing the possibility of using a helipad for placing equipment, increasing the survivability of the power plant, improving the visibility from the wheelhouse along the ship's heading when approaching the shore.

This goal is achieved by organizing two superstructures with the wheelhouse located in the bow superstructure, and a through passage and a hangar with a retractable section in the aft superstructure, connecting the helicopter and cargo platforms, and the location of the main power plant (GPU) in two compartments.

The present invention is illustrated in the drawing.

The architectural type of the ship includes a bow 2 and aft 4 superstructure, a cargo platform 3 connected to a helipad 7 through a through passage. In the bow and stern parts of the ship there are bow 1 and stern 8 landing devices and in the middle part there are inter-deck gangways for loading and unloading equipment. Hangar 5 is made with a retractable section 6 in the aft superstructure. The main power plant is located in two engine rooms.

The present invention is used as follows:

- the location of the wheelhouse in the bow superstructure provides the best visibility when landing equipment on an unequipped shore;

- the presence of a hangar with a retractable section in the aft superstructure ensures the permanent deployment of two helicopters;

- the helipad is heated, which allows its use at subzero temperatures;

- a through passage in the aft superstructure, connecting the cargo area in the middle part of the ship with the helipad, ensures the placement of equipment on the helipad (in the absence of a helicopter);

- inter-deck gangways make it possible to accept equipment onto the upper deck from two directions (from the bow and stern), while reducing the loading and unloading time;

- a through cargo hold, providing loading and unloading of equipment from the bow and stern;

- the main power plant is two-echelon, which ensures increased survivability of the ship.

Claims (1)

A transport vessel for carrying out cargo operations on an unequipped shore, containing a superstructure, a helipad in the aft part of the ship behind the superstructure, a cargo platform, a through cargo hold, a stern and bow landing devices, characterized in that the superstructure is divided into bow and stern superstructures, with the location of the undercarriage wheelhouse in the bow superstructure, the location of a through passage and a hangar with a retractable section in the aft superstructure, connecting the cargo area with the helipad and allowing equipment to be placed on the helipad (in the absence of helicopters), the main power plant is two-echelon.
