Detailed Description

Needless to say, in the cross-sea island combat, oil security is an important content of the cross-sea island combat logistics. When in war, the enemy must implement blockage and destroy harbor operation, and the army is very likely to face the unfavorable situation that no ports and wharfs are available. Under the condition that the enemy bank has no port and wharf, the oil transportation guarantee of the coastal sea is organized, and is a necessary means for implementing the oil guarantee of the beach by the force of the battle logistics oil.

The civil oil tankers are quite rich in resources, and the situation of insufficient transportation capacity of the standard oil tankers can be made up through the civil oil tankers. It is therefore necessary to adapt it appropriately to meet the unloading of oil in the case of high sea conditions without available ports.

In the present application, the applicant believes that it may be retrofitted to construct a high sea state oil offloading system. Therefore, the unloading system can fill the gap of insufficient quantity of standard equipment, greatly improves the large-scale login operation oil guaranteeing capability, and simultaneously greatly reduces the manufacturing cost and the maintenance cost of the oil unloading equipment, thereby having extremely high economic value and military value.

Therefore, the method has important significance in providing uninterrupted oil source supplement for the logistic oil duty of the cross-sea island fight cluster by constructing the sea-to-shore oil unloading channel which is high in sea condition adaptation, good in maneuvering performance and large in conveying flow by using the civil ship.

There have been some attempts in the art to achieve modular oil delivery systems, such as by rapid construction of barge carriers.

The system mainly comprises a self-propelled deck barge and a finished oil tanker. However, the finished oil vessel is moored in four points. It is difficult to apply to civil oil tankers. Because the civil oil vessel itself has no mooring equipment required for four-point mooring. And, even if the civil oil tanker is retrofitted with a mooring apparatus, the time consumed when throwing the four-point mooring becomes long due to its poor operability.

Furthermore, four point moorings have limited ability to adapt to sea conditions. If the mooring of the oil tanker is to be satisfied under high sea conditions, the size of the anchor chains, ropes and anchors in the mooring system is increased, which also results in adverse effects on the operation of the battle time deployment.

Furthermore, another problem with the above solutions is that floating pipeline systems are employed by all sea-to-shore oil offloading techniques. That is, the oil line floats on the sea surface, and is thus greatly affected by the wave current. Moreover, the oil hose has limited working pressure and tensile strength, so that the whole system has limited capability of adapting to sea conditions and oil conveying distance.

In order to overcome the above drawbacks, the applicant constructed a high sea state oil unloading system using a civil ship in this embodiment, in order to fully utilize the civil ship to transport oil from sea to shore on the sea floor under high sea conditions.

The system mainly uses a barge and a multipurpose workboat.

Wherein the barge is retrofitted to add sea-to-shore oil offloading equipment for constructing a subsea oil offloading path that is compatible with high sea conditions.

The multipurpose workboat can be modified without modification. It can be used as a tug for an integrated anchor base for a single point mooring system for a tanker. And when the high sea state oil unloading system is unfolded, the integrated anchoring base plate is assisted to be laid, and the single point mooring of the oil tanker is completed.
