Background
The export operation of the offshore platform is one of large-scale offshore operations, and the export operation of the mobile offshore platform is firstly tried in the Bohai sea area, so that the selection of a mooring mode is very important. Considering that the export area is generally near the platform, submarine pipelines and sea cables in the area are distributed densely, the fewer the anchor points are, the better the export mooring operation of the offshore oil mobile platform is required to be met, and the export mooring operation can also be used for the export requirement of fixed production facilities.
Most of the existing fixed offshore platforms adopt a two-point mooring mode, but the two-point mooring mode has the defects of easy influence of stormy weather, complex mooring cable and low speed. Since the environmental conditions and sea conditions of the mobile offshore platform change, a mooring mode with convenient installation and high output efficiency is required. In addition, the two-point mooring mode of the offshore fixed platform has relatively high construction cost, can not be recycled, and is not suitable for offshore mobile platforms.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that novel portable offshore platform defeated operation moored provides a marine mobile platform crude oil defeated outward big holding power anchor and two cable mooring systems, adopts the mooring method of big holding power anchor and two cables to carry out defeated operation outward, has safe and reliable, and the mooring is simple, and the installation is swift, does not receive the influence of climatic sea condition, and engineering cost is low, but advantages such as reuse.
In order to solve the technical problem, the utility model discloses a following technical scheme realizes:
a crude oil export high holding power anchor and double-cable mooring system for an offshore mobile platform comprises an oil tanker, wherein the head part of the oil tanker is fixed through the high holding power anchor, and the tail part of the oil tanker is connected to the offshore mobile platform through double-cable mooring, so that single-point double-cable mooring is formed.
Furthermore, the high holding power anchor is sequentially connected with an anchor chain, a steel cable, an interception shackle, a floating cable and a positioning anchor float and then fixed on the mooring bollard at the head of the oil tanker.
Further, the tail part of the oil tanker is moored on a mooring cable pile of the offshore mobile platform by adopting a double cable.
The utility model has the advantages that:
the utility model adopts a mooring mode of a high-holding-power anchor and a double cable, the high-holding-power anchor connected with the bow has strong ground-holding capacity, and the steel cable has strong force-unloading capacity, can be thoroughly and firmly attached to the sea bottom and is firmly attached to the surface of the sea bottom; the double cables moored at the stern are moored on the quick unhooking of the platform, so that the oil lifting wheel can be quickly separated from the platform in emergency to prevent collision, and the safety is good;
the utility model adopts a mooring mode of a high holding power anchor and a double cable, the high holding power anchor and the steel wire cable rope can be recycled, no waste is generated, no pollution is caused to the environment, and no operating cost is increased for environmental protection treatment;
the utility model adopts a mooring mode of a high holding power anchor and a double cable, so that the high holding power anchor is convenient to embed and recover, the construction difficulty is small, and the construction period is short; the mobile platform is very suitable for a mobile platform with an unfixed operation area and short sea time; therefore, the utility model has lower construction cost and lower comprehensive cost than the traditional double-point mooring mode of the suction anchor;
(IV) the utility model discloses it floats to add on the floating hawser of high holding power anchor and establish floating anchor, obvious on the sea, easily assist the tow boat discovery to the cooperation tow boat is conveniently dragged for.

Detailed Description
For further understanding of the contents, features and effects of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings as follows:
as shown in fig. 1, the embodiment provides a system for transporting a large holding power anchor and a double-cable mooring for crude oil export of an offshore mobile platform, which includes an oil tanker 7, wherein the head of the oil tanker 7 is fixed by the large holding power anchor 1, and the tail of the oil tanker 7 is connected to an offshore mobile platform 9 by adopting the double-cable mooring, so that the fore and the aft of the oil tanker are moored to form a single-point double-cable mooring.
Specifically, the high-holding-power anchor 1 is connected with an anchor chain 2 with a connecting shackle, the anchor chain 2 is connected with a steel cable 3 with the length of 800 meters, the steel cable 3 is connected with a floating cable 5 with the high strength of 50 meters through an interception shackle 4, and the floating cable 5 is connected with a positioning anchor float 6 and then is connected with a mooring pile 8 at the head of a tanker 7. The high-holding-power anchor 1 has strong holding power and strong steel cable force-unloading capability, can be completely and firmly attached to the seabed and can be firmly attached to the surface of the seabed.
The oil tanker 7 is moored on the mooring bollard 8 of the offshore mobile platform 9 by double cables at the tail part, and the oil tanker 7 and the offshore mobile platform 9 can be separated quickly to prevent collision under emergency conditions.
The mooring bollards 8 of the oil tanker 7 and the mooring bollards 8 of the offshore mobile platform 9 are both provided with quick unhooking devices, and the quick unhooking devices are provided with field tension meters and are used for export mooring operation for the first time. The design of the rapid unhooking device of the embodiment has the rated pressure of 0.7MPa, the rated traction force of 30KN, the rated power of 8KW and the maximum rope speed of 10 m/min.
Although the preferred embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments, which are only illustrative and not restrictive, and those skilled in the art can make various changes without departing from the spirit and the scope of the invention as claimed.
