Problems solved by technology

At the same time, since the unmanned merchant ship adopts the stern type, it has the same disadvantage as most stern type ships, that is, the tail tilt problem will occur when leaving the port empty-loaded.
At the same time, since the ship type is a non-ballast water ship type, there is no ballast water to dynamically adjust the ship's floating state, so the problem of stern inclination of unmanned merchant ships when leaving the port with no load is more prominent

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] combine Figure 1 to Figure 6 , the ship type of the present invention is a horizontally inclined ship bottom, so that the hull presents an obvious V-shaped non-ballast water ship type. It has been verified by experiments that this scheme can meet the performance requirements of the ship in most sea conditions. Therefore, the ship in the present invention will not produce environmental hazards caused by carrying ballast water; the bottom elevation angle m is 22.5°. After calculation and evaluation of the use effect of the bulbous bow, the ship-shaped bow of the present invention does not adopt the design of the bulbous bow, but adopts the forward-leaning bow 2 . The shape of the tail adopts a V-shaped cross-section similar to that of a square stern, which transitions from a smooth line close to a straight line to the stern sea...

Abstract

The invention provides a merchant ship without ballast water. The overall layout design is applicable to an unmanned ship in the further. The merchant ship without ballast water is an unmanned oil ship without ballast water provided with a deep V-shaped ship body. Due to the fact that a power system of the ship is arranged on the tail, no seaman exits in the ship and no ballast water is used for adjusting the floating states of the ship in different working stations, the ship type is applicable to the unmanned ship, the problem that tail inclination is too large in the empty-ship departure state of the ship is solved, and it can be also ensured that the ship has the good floating state in the full-load departure working condition through computing and checking.

Description

technical field [0001] The invention relates to a water merchant ship, in particular to a water merchant ship without ballast. Background technique [0002] At present, with the advancement of science and technology, unmanned cars and unmanned aircraft have appeared. After realizing the unmanned of various small boats, people began to plan Realize unmanned large commercial ships, that is, unmanned commercial ships. Unmanned merchant ships are highly automated and intelligent. The main difference between them and traditional merchant ships is that there are no personnel stationed on board, so they have their own characteristics in terms of general layout. [0003] Unmanned merchant ships must ensure safety and environmental protection design principles, and adopt a ship shape design without ballast water, that is, a deep V-shaped hull. At the same time, since the unmanned commercial ship adopts the stern type, it has the same disadvantage as most stern type ships, that is, ...
