Abstract

The utility model discloses an oil tanker without seawater ballast. The oil tanker comprises a tanker body and a cargo oil hold, wherein the cargo oil hold is arranged in the tanker body, and the bottom of the tanker body is V-shaped. The oil tanker saves high cost for constructing or maintaining a seawater ballast tank due to no seawater ballast tank provided; and meanwhile under the condition that the water discharge capacity is constant or almost constant, the shape of the tank body under water become narrower so that the tank body resistance can be reduced and the energy used is saved.

Description

A kind of oil carrier that does not have seawater ballast

Technical field

The utility model relates to ship design and manufacturing field, relates in particular to a kind of oil carrier that does not have seawater ballast.

Background technology

As shown in Figure 1, at present, except that some before 20 to 30 years early stage aged oil carriers of building, traditional oil carrier has all that flat type hull bottom 1, cargo oil tank double hull configuration 2, cargo oil tank scope are provided with special-purpose seawater ballast tank 3, the head and the tail zone is provided with features such as regulating seawater ballast tank.And traditional oil carrier has enough cargo oil tank volume loadings, its hull to be loose ship type basically for guaranteeing, and tonnage is bigger just more plentiful.When ship in ballast is navigated by water, be immersed in all under water and prevent that for guaranteeing tail undercarriage wave to the bouncing of stem hull bottom, utilizing the method for seawater ballast usually, increase ship weight and will squat, thereby guarantee the normal navigation of boats and ships to certain drinking water.

But; build the technology of this special-purpose seawater ballast tank; the japanning of adopting; sandblast application workshop and corollary equipment and ballast water treatment plant system must meet the IMO's of International Maritime Organization (IMO) the relevant regulations of " ballast tank of ship protective coat performance standard " and " international shipping press to be cut out water and deposit control and management contract "; this has just increased the shipbuilding cost of oil carrier and the expense of boats and ships maintenance and maintenance greatly, brings for shipbuilding facilities and Ship-repairing Industry and seriously influences.

The utility model content

The high cost that brings because of construction or maintenance seawater ballast tank in order to reduce, and save the energy, the utility model proposes new technical solution, particular content is as follows:

A kind of oil carrier that does not have seawater ballast comprises hull, cargo oil tank, and described cargo oil tank is built in the hull, and described hull bottom is V-shaped.Below the ship in ballast drinking water and under the light ship disphacement unmodified condition, utilize the cross-sectional area principle of equivalence, at the boats and ships length range, at the bottom of changing novel V-type into by tradition is flat, just can reach the boats and ships baseline and move down certain depth, get final product so that drauht increases the purpose of corresponding value, and the cavity between hull and the cargo oil tank no longer loads seawater.

So just can be limited by " ballast tank of ship protective coat performance standard " and " international shipping is pressed and cut out water and deposit control and management contract ", also avoid for satisfying the high cost that above-mentioned standard is brought.

And the head and the tail zone of described hull also is respectively equipped with regulates the cabin, and described adjusting cabin is fresh water tank or fuel oil tank, and its arrangement principle is the relevant regulations of absorbing water from beginning to end when meeting the shipping register standard to ship in ballast.And when oil carrier needed the fresh water washing of tanks, the cavity between hull and the cargo oil tank then can be arranged the washing of tanks fresh water tank.Satisfied the demand of user to diversified function.

In addition, described cargo oil tank bottom is V-shaped, like this clearing the ship of Cargo Oil residual liquid is become very easy.

The utility model produces following beneficial effect:

The utility model is not because boats and ships have seawater ballast tank, the high cost of having saved construction or maintenance seawater ballast tank and having brought, simultaneously can make boats and ships under the constant or basic unmodified condition of displacement, it is modest that the underwater shape of hull becomes, thereby can reduce hull resistance, save the use of the energy.

Description of drawings

Fig. 1 is traditional tank barge midship section figure;

Fig. 2 is oil carrier midship section figure at the bottom of the utility model V-type.

The specific embodiment

As shown in Figure 2, the utility model comprises hull 1, cargo oil tank 2, and cargo oil tank 2 is built in the hull 1.Hull 1 bottom and cargo oil tank 2 bottoms are V-shaped respectively.And the head and the tail zone of hull 1 also is respectively equipped with regulates the cabin, and this regulates the cabin can be fresh water tank or fuel oil tank.

Below the ship in ballast drinking water and under the light ship disphacement unmodified condition, utilize the cross-sectional area principle of equivalence, at the boats and ships length range, at the bottom of changing novel V-type into by tradition is flat, just can reach the boats and ships baseline and move down certain depth, get final product so that drauht increases the purpose of corresponding value, and the cavity 4 between hull 1 and the cargo oil tank 2 no longer loads seawater.This V-type design-calculated oil carrier; seawater ballast tank need not be set; just can reach the identical function of the oil carrier that is provided with seawater ballast tank; and need not be limited by " ballast tank of ship protective coat performance standard " and " international shipping is pressed and cut out water and deposit control and management contract "; also avoid for satisfying the high cost that above-mentioned standard is brought, saved shipbuilding and maintenance cost.

And cargo oil tank 2 bottoms are V-shaped, like this clearing the ship of Cargo Oil residual liquid become very easy.

And in the adjusting cabin that the head and the tail zone of hull 1 is provided with respectively, its arrangement principle is the relevant regulations of absorbing water from beginning to end when meeting the shipping register standard to ship in ballast.And when oil carrier needed the fresh water washing of tanks, the cavity between hull and the cargo oil tank then can be arranged the washing of tanks fresh water tank.Satisfied the demand of user to diversified function.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technical scheme described above and design.
