Abstract

The utility model discloses a stabilizing system for a marine engineering working/living multifunctional vessel. The stabilizing system comprises four anti-swing cabins distributed at the side portions of a stem and a stern, four inclination sensors respectively installed on the bulkheads of the four anti-swing cabins, and a charging and discharging water pump installed in a pump cabin at the waist of the vessel. The charging and discharging water pump is connected to the four anti-swing cabins through a water charging and discharging pipe. When the marine engineering working/living multifunctional vessel carries out a lifting work, the torque generated makes the vessel incline laterally or longitudinally. In a novel ballast balancing method employed in the utility model, an extra torque is added to balance the torque generated by a crane in lifting weight, thereby ensuring balance of the entire vessel, restoring the vessel to a balance state, and maintaining the stability of the entire vessel. The stabilizing system is advantageous in that a vessel, of which the structure and performance are not changed, can be prevented from lateral or longitudinal inclination when the vessel carries out a lifting work. The stabilizing system satisfies national security conventions.

Description

The stability system of a kind of ocean engineering work/inhabitation multi purpose ship

Technical field

The utility model relates to the stability system of a kind of ocean engineering work/inhabitation multi purpose ship, is applicable to guarantee that ocean engineering work/accommodation vessel at operation, non-operating condition, is in stabilized conditions.

Background technology

Marine petroleum development is in the wooden trestle well-digging of markon's good fortune Ya Zhou West Coast frame since the U.S. in 1887, opened since then the prelude of world ocean oil exploration. from the coastal waters to the off-lying sea, from the shallow sea to the deep-sea, offshore oil drilling and exploitation obtain develop rapidly, its corresponding supporting engineering and service facility require also more and more higher, the operational base of implementing at present sea-bottom oil-gas exploration and exploitation is marine drilling platform, staff and used goods and materials are all finished by autogyro above it, because the limitation of autogyro can not satisfy the demand of present marine drilling platform power.It is therefore comprehensive that ocean engineering work/the inhabitation multi purpose ship is the ship-related products of oil-gas mining industry first-selection.

This ocean engineering is worked/inhabitation multi purpose ship configuration 300T full-rotary crane, the 300T full-rotary crane in the course of the work, because the variation of lifting cargo weight produces the moment of boats and ships center of gravity different, thereby cause that boats and ships ceaselessly rock, even generation integral body is significantly rocked, have a strong impact on workman's work and living conditions, as at boisterous harsh environment, the stability that can not keep boats and ships, that may bring graver results, and therefore, need to take measures, make this ship be in all the time stabilized conditions, otherwise do not satisfy the requirement of world security pact.

The utility model content

The purpose of this utility model provides a kind of ocean engineering work/inhabitation multi purpose ship that effectively prevents under hoisting operation or non-operating condition, and vertical or horizontal inclination occurs, and proposes a kind of technical scheme that solves stability.

The technical solution adopted in the utility model by 4 rolling tanks, 4 slant sensors, control conveniences, advance dewatering pump, communication cable, control cables and formed the whole stability of boats and ships system, 4 rolling tanks are arranged in stem and ship stern bow side position, 4 slant sensors are installed on respectively bow, stern bow side rolling tank bulkhead, advance dewatering pump and be installed on hull midships section pump room, connect 4 rolling tanks of dewatering pump and stem stern by intake-discharge pipe.

The present utility model ocean engineering works/the inhabitation multi purpose ship under the prerequisite that does not change hull structure and performance, realize boats and ships when carrying out hoisting operation, prevent that boats and ships from vertical or horizontal inclination occuring, and satisfies the world security pact.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and implementation.

Fig. 1 is plan sketch of the present utility model.

Wherein: 1, the first rolling tank, the 2, second rolling tank, the 3, the 3rd rolling tank, the 4, the 4th rolling tank, 5, slant sensor, 6, advance dewatering pump, 7, control convenience, 8, intake-discharge pipe, 9, communication cable, 10, control cables, 11, the 300T full-rotary crane.

The specific embodiment

As shown in Figure 1, when 300T full-rotary crane 11 during at hoisting operation, bow bow side the first rolling tank 1, slant sensor 5 in the 4th rolling tank 4, sense the hull bow and be in the sinking state, by communication cable 9, with the sinking signal feedback to control convenience 7, after control convenience 7 receives signal, by control cables 10, send instruction to advancing dewatering pump 6, respectively to the second rolling tank 2, the 3rd rolling tank 3 advances the water action, when the second rolling tank 2, slant sensor 5 in the 3rd rolling tank 3, after sensing hull and being horizontal, by communication cable 9, with signal feedback to control convenience 7, after control convenience 7 receives signal, by control cables 10, send instruction to advancing dewatering pump 6, stop the second rolling tank 2, the 3rd rolling tank 3 carries out the pump hydrodynamic(al) and does.

After 300T full-rotary crane 11 hoisting operations are complete, bow bow side the first rolling tank 1, slant sensor 5 in the 4th rolling tank 4, sense the hull bow and be in propradation, by communication cable 9, rising signals is fed back to control convenience 7, after control convenience 7 receives signal, by control cables 10, send instruction to advancing dewatering pump 6, respectively to the second rolling tank 2, the 3rd rolling tank 3 carries out the draining action, when the second rolling tank 2, slant sensor 5 in the 3rd rolling tank 3 is after sensing hull and being horizontal, by communication cable 9, with signal feedback to control convenience 7, after control convenience 7 receives signal, by control cables 10, send instruction to advancing dewatering pump 6, stop the second rolling tank 2, the 3rd rolling tank 3 carries out the draining action.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.

Claims

1. the stability system of ocean engineering work/inhabitation multi purpose ship, comprise by 4 rolling tanks, 4 slant sensors, enter the stability system that dewatering pump, control convenience, intake-discharge pipe, communication cable, control cables form, it is characterized in that 4 rolling tanks are arranged in stem and ship stern bow side position, 4 slant sensors are installed on respectively bow, stern bow side rolling tank bulkhead, advance dewatering pump and be installed on hull midships section pump room, connect 4 rolling tanks of dewatering pump and stem stern by intake-discharge pipe.
