Furthermore, it is required that the present application is understood, not simply by the actual terms used but by the meaning of each term lying within.
The application discloses a temporary anchor using method for positioning an unpowered floating body, which is suitable for offshore new energy engineering construction. Before the temporary anchor is used, the components of the temporary anchor are first assembled.
Preferably, as shown in fig. 1, the temporary anchor includes an anchor head 10, an anchor chain 20, an anchor wire 30, and an anchor line 40, which are sequentially connected as one body.
In addition, the temporary anchor should also include a general-purpose anchor wire and an anchor float.
Particularly preferably, the anchor head is preferably a triangular high-holding-power hall anchor, and the high-holding-power anchor is preferably 3 tons. The anchor chain is preferably 20mm in diameter with a crosspiece and preferably 20m in length. The length of the anchor wire is preferably 30m and the diameter is preferably 30mm. The length of the anchor cable is preferably 50m and the diameter is preferably 80mm.
The lengths of the anchor chain, the anchor steel wire and the anchor cable are all exemplified, the specific lengths of the anchor chain, the anchor steel wire and the anchor cable are required to be selected and determined according to the requirement of the floating body in practical application, the anchor chain, the anchor steel wire and the anchor cable are not limited by the examples, and other length selections are also within the protection scope of the application.
The temporary anchor using method comprises the following steps:
step S 1 The anchor position of the temporary anchor, i.e. the azimuthal distance relative to the floating body, is determined.
In the embodiment of the application, the anchor-down position of the temporary anchor has large selection space and mobility, can better meet the current sea condition and the required floating body positioning requirement, and performs optimal temporary auxiliary positioning. The safety and the effectiveness are ensured in the aspect of assisting the floating body in resisting the flow and the wind. If abnormal conditions such as anchor running occur, the anchor moving device has the biggest advantage of being capable of completing anchor moving operation again in a short time. If necessary, after the anchor is lifted, the ship machine assisting the anchor can directly provide the towing force for the floating body.
The distance between the temporary anchor and the floating body is required depending on the situation, in general, the step S 3 The length of the anchor rope of the temporary anchor is 80-100m under the condition that the sea current flow speed is less than 2 knots and the floating body displacement is less than 5 kilotons.
For example, under the condition that the water displacement of the floating body is less than 1 kiloton in 2-3 knots of ocean currents, a temporary anchor with the anchor head of 3 tons and large grabbing force, the anchor chain diameter of 20mm, the length of 20m, the anchor wire diameter of 30mm, the length of 30m, the anchor rope diameter of 80mm and the length of 50m is used, and the construction requirements can be met.
For another example, under the condition that the water displacement of the floating body is below 5 kilotons in 2-3 knots of ocean currents, a temporary anchor with the anchor head of 3 tons and the large grabbing force is used, wherein the anchor chain is 30mm in diameter, 30m in length, 30mm in anchor wire diameter, 30m in length, 80mm in anchor rope diameter and 100m in length, and the construction requirements can be met.
Step S 2 The anchor head is thrown to a set position through an anchor boat or a ship with an anchor throwing function. And placing an anchor lifting steel wire and an anchor float.
And according to the set anchor-down position and the distance between the temporary anchor and the floating body, throwing the anchor towards the sea surface.
Preferably, the anchor head holding power and the bearing direction of the floating body are consistent.
Temporary anchors are much lighter in weight than conventional tie-down anchors. According to navigation experience, the large-grabbing anchor with about 3 tons can meet the requirement that the floating body with the water displacement within 5 kilotons can be temporarily positioned in the sea area with the sea water flow rate less than 3 knots. In addition, the operation of throwing the temporary anchor has the advantages of simple and convenient operation, short time consumption, less required manpower, small ship machine and the like.
Step S 3 Sequentially throwing down an anchor chain and an anchor steel wire towards the floating body through an anchor boat or a ship with an anchor throwing function;
step S 4 Pulling the anchor head to the mud-entering force through the anchor cable;
step S 5 The anchor rope is handed to an operator on the floating body through the lead rope, and then the anchor rope is tied to the bollard of the floating body.
According to the description of the method process, the temporary anchor has the greatest advantages that the floatability of the anchor cable is effectively utilized, and 1-2 persons can finish the mooring rope in a short time due to light weight and floatability on the sea surface, so that the mooring is extremely safe and convenient. The structure and the use method show the mobility and portability of the temporary anchor in use and operation.
In summary, the temporary anchor using method for positioning the unpowered floating body has the following advantages:
1. easy and convenient to operate
The original traditional operation needs to use the positioning anchor for temporary positioning, the structure needs to occupy the positioning anchor, the anchor head is heavy and difficult to operate, the anchor breaking process is time-consuming and has larger operation risk. The temporary anchor is small in size and light in weight, and is extremely simple, safe and reliable in anchor throwing operation of a ship machine and cable untying operation of personnel.
The temporary anchor using method can be adjusted at any time. The temporary anchor has small volume and light weight, is extremely simple, is safe and reliable, and can be used as the anchor for the ship machine and the cable untwisting operation for personnel.
2. Novel structure
The anchor chain provides auxiliary holding power and ensures holding power of the anchor head. The anchor steel wire is connected with the anchor chain and the anchor rope, so that the holding power of the anchor head is protected, the anchoring tension is effectively provided, and the loss tension caused by floating of the anchor rope is reduced. The buoyancy of the anchor line provides extremely convenient operating conditions for untwisting the line, as well as safe operating conditions.
3. With other auxiliary functions
Besides temporary positioning, the temporary anchor has the characteristic of cooperation dragging in emergency rescue, and has the advantages of high response speed, remarkable effect, safety and reliability.
