Embodiment Construction

[0012] The multifunctional small water surface craft is mainly made up of platform 6, submerged body 8 and column 7 fixedly connecting them, all-welded structure. The platform 6 is composed of a watertight structure, and there are four positioning piles 5, a drilling rig frame 4, a head and tail anchor 2, a side anchor 3, an operating room, a living room, etc. on the platform; there is a surrounding well for underwater operations in the middle of the deck; There are multiple separate watertight compartments in the floating body 8, equipped with a powerful ballast system, and ballast tanks are set; in addition, the platform has a large buoyancy reserve, no matter the platform, column or floating body is damaged symmetrically or asymmetrically, there will be strong buoyancy. Survival support force; There is respectively a screw propulsion device 1 on both sides of the submerged body tail, and a screw side thruster 9 is respectively arranged on the submerged body head; four sinkin...

Abstract

The invention discloses a multifunctional small water-plane area twin hull, which is characterized in that: a guide pile, a bower anchor, a stern anchor, a side anchor, cables connecting the guide pile, the bower anchor, the stern anchor and the side anchor, and a windlass are arranged on a platform; four heavy punches for the anchors are positioned at the bottom of a submerged body; a spiral propeller is respectively arranged at both sides of the stern and both laterals of the head part of the submerged body. The invention has the advantages that: as the small water-plane area, disturbing force of waves on the platform and resonance between the hull and the wave, as well as range of shaking and swaying for the platform are small, the positioning accuracy and working efficiency are guaranteed in operation, the comfort level and feeling of safety are improved for the personnel, and requirements for large working area of the deck and smallest range of swaying and hoisting are maximally met; since the resistance from the wave and the interference of the water surface is small during the sailing, the sailing is fast and stable and the energy is remarkably saved; free sailing, flexible turning, accurate transverse movement and positioning are realized.

Description

technical field [0001] The invention belongs to the field of multifunctional small waterplane surface ships. Background technique [0002] At present, most projects such as underwater drilling and blasting, reef blasting and drilling are completed by non-self-propelled barges / self-elevating barges. Using this kind of non-self-propelled barge / self-elevating barge to implement underwater drilling and explosive reefs is subject to the problems of wind waves, swell waves, and water depth. The larger the water plane, the greater the interference by wind waves. As a result, the technical problems such as the bearing capacity of pile legs and ultra-deep precise positioning have not been well resolved, which directly affects the project expansion ability, quality and safety, and also affects the work and life of operators. [0003] In the shipping industry at the present stage, in order to increase the speed of navigation, a kind of small water surfa...
