Example Embodiment

[0033] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0034] A ship positioning anchor system, the ship positioning anchor system adopts four anchors for positioning, the bow and stern are each provided with an upper deck and a lower deck, and the upper deck is an open deck used for engineering operations; a positioning winch Set on the lower deck, the wire rope is led out by the positioning winch and then passes through the vertical fairlead 2, the direction of the wire rope changes to vertical upwards, passes through the upper deck, enters the deckhouse 11 specially set up on the upper deck, and passes through the vertical at the top of the deckhouse 11. The fairlead 2 is changed to a horizontal rearward direction, passing through the rotating fairlead 4, and the end of the wire rope is connected to the positioning anchor 10; the rotating fairlead 4 is arranged at the top of the side wall of the hull.

Abstract

The invention relates to a ship positioning anchor system, and belongs to the technical field of ship positioning anchors. Four-anchor positioning is adopted for the ship positioning anchor system. The ship positioning anchor system is characterized in that a bow and a stern are both provided with an upper-layer deck and a lower-layer deck, and the upper-layer decks are exposed decks for engineering work; positioning winches are arranged on the lower-layer decks; steel wire ropes pass through vertical fair-leads (2) after being led out through the positioning winches, the direction of the steel wire ropes is changed into the vertically upward direction, the steel wire ropes penetrate through the upper-layer decks to enter deck houses (11) specially arranged on the upper-layer decks, the direction of the steel wire ropes is changed into the horizontally backward direction through vertical fair-leads (2) at the tops of the deck houses (11), the steel wire ropes penetrate through rotary fair-leads (4), and the tail ends of the steel wire ropes are connected with positioning anchors (10); the rotary fair-leads (4) are arranged at the top end of the side wall of a hull.

Description

technical field [0001] The invention relates to a ship positioning anchor system, which belongs to the technical field of ship positioning anchors. Background technique [0002] When marine engineering ships are operating at sea, many operations require the ship to keep the ship's position unchanged, such as drilling operations, diving operations, hoisting operations, etc. There are two ways of positioning in shallow water, namely anchoring positioning and dynamic positioning. Assessed from the economic point of view, mooring positioning is less costly than dynamic positioning. But it takes a long time to carry out the anchor operation, [0003] When the positioning anchor system is arranged, it often has a greater impact on the ship's arrangement. As far as the commonly used four-anchor positioning is concerned, there are two ways to arrange the stern windlass. One is to arrange on the main deck. The deck area is at a premium. The other is arranged under the main deck....
