Safety device against leakage from ships, especially tankers

A ship such as a tanker for the transport of oil and oil products, is provided with a safety device to prevent leakage of the product being stored or transported. The safety device comprises a shield which preferably is flexible and extends along the ship''s hull in spaced relation thereto so as to define vertically extending narrow spaces at the inner side of the hull. Said narrow spaces are opening in the bottom region of the ship and shall when the ship is used contain a liquid having the same or a higher density than the transported product. As an example the product may rest on a bed of water at the ship''s bottom, water than also being present in the said narrow spaces. If for instance due to a collision a hole is formed in the ship''s hull the liquid level in the actual narrow spaces will be adapted after the sea level whereby the level of the product in the cargo space takes a balanced position in which leakage of the product is prevented. As an alternative to water the transported product proper may be contained in the narrow spaces in which case a small leakage may occur if the hull of the ship becomes damaged.

Wegen des hohen Erstarrungspunktes der Produkte müssen alle Leitungssysteme mit einer Begleitheizung und einer ausreichenden Isolierung versehen werden. Hierzu eignet sich eine Thermalölanlage, die gleichzeitig die Notheizung (4) der Tanks (1) versorgt. Da die Tanks nicht mit Wasser gefüllt werden dürfen, sind gesonderte Ballasttanks (17) zwischen den Rümpfen anzuordnen. Das Schiff muß so ausgerüstet sein, daß es den Sicherheitsbestimmungen für K1-Schiffe entspricht. In the case of double hull ships for the transport of pitch at 200 to 300 ° C, particular care must be taken to ensure that the tanks are well insulated and that the gas space in the tanks is inert (1). The thermal expansion is to be taken into account by expansion joints and slide bearings (3). Due to the high solidification point of the products, all pipe systems must be provided with trace heating and adequate insulation. A thermal oil system is suitable for this, which simultaneously supplies the emergency heating (4) of the tanks (1). Since the tanks must not be filled with water, separate ballast tanks (17) must be arranged between the hulls. The ship must be equipped in such a way that it complies with the safety regulations for K1 ships.

Tanker for the prevention of cargo oil spillage

A tanker which can reliably prevent the outflow of cargo oil from cargo oil tank sections (1, 2, 105, 106) in the ship body in the event of damage or injury to an outer plate (8, 9) of the ship body has a double-sided hull construction (4, 104) arranged on opposite sides of each cargo oil tank in the ship's body and a mid-height deck (3, 118) arranged to divide each cargo oil tank into an upper cargo oil tank (2, 106) and a lower cargo oil tank (1, 105). To reliably prevent the outflow of cargo oil in the event of damage or injury to the ship body due to stranding, collision or similar malfunction, the height (H) of the mid-height deck (1, 118) as measured from the ship bottom (8, 108) is determined so that the pressure of cargo oil exerted on an outer plate of the ship's side wall will not be higher than the pressure of sea water. An access trunk (5, 112) and pressure control devices (6, 7, 113, 114) serve for degassing cargo tank sections.

Arrangement for dividing a ship's free liquid surface

ABSTRACT OF THE DISCLOSURE An arrangement is disclosed for dividing the full liquid surface of ships to enable general cargo and bulk cargo ships to carry liquid cargo. The arrangement overcomes the problem of such a ship becoming unstable when carrying liquids. The arrangement is attached removably in a hatch and consists of at least one unit having interconnected parallel upright metal sheets which form a plurality of parallel shieldings, each unit being so dimensioned so as to fit into at least a portion of a hatch adapted to be pla-ced with the metal sheets substantially vertically upright in the hatch so that the lower edge of the metal sheets is located below the upper surface of a liquid cargo and so that the upper edge of the metal sheets is located at or above the liquid surface.

OIL FOR PREVENTION AGAINST SPILLING OF LOAD OIL

Structure and method for installing fuel tank

An installation structure of a fuel tank is disclosed. The installation structure of the fuel tank according to an embodiment of the present invention includes a fuel tank in which liquid fuel is stored, a hull having an installation space in which the fuel tank is installed, A projecting member, and an insertion groove formed on an inner surface of the installation space and into which the projecting member is inserted.

Protection liquid tank structure of explosion high-speed fragment under water resistance

一种抗水下爆炸高速破片的防护液舱结构，属于舰船结构防护技术领域。本发明解决了现有防护液舱的防护性能差的问题。防护液舱内填充有吸收液体，且布置有若干内隔板及若干加强筋，内隔板及每个加强筋均沿船长方向布置，若干内隔板由上到下依次布置，若干加强筋与若干内隔板交错布置，每个内隔板的两侧分别与液舱外板和液舱内板固接，每个加强筋的两端分别与横舱壁固接。在沿着船长方向设置多组加强筋和内隔板，不仅能够改变爆轰产物与破片的运动轨迹，使其发生偏转，同时能够反射破片侵彻液舱时产生的激波，以此降低破片对后续侵彻液舱内板及防御纵壁时产生的破坏。

Liquid cargo vessel

In order to increase speed and reduce fuel consumption, this liquid cargo vessel is provided with: a tank (108) in which liquid cargo is loaded; and a vessel body (101) which accommodates the tank (108). The liquid cargo vessel is configured to be able to submerge, is further provided with a water flow path (103) allowing flowing of water during propulsion of the liquid cargo vessel, and is configured to be able to enter into a submerged state by injecting water into the water flow path (103) and to enter, by draining water in the water flow path (103), into a floating state which allows loading and unloading of liquid cargo into and from the tank (108).
