The installation and operation of the drilling equipment can be carried out smoothly and quickly at the actual installation site, and in particular, the floating drilling facility for inputting and operating the pressure vessel and the drilling equipment into which the drilling equipment is inserted can be installed at a position adjacent to the seashore It is possible to easily fix the floating drilling equipment through the mooring device connected to the seawall, thereby making it possible to easily and conveniently place the floating drilling equipment in a stable state without operating a separate DP system for fixing the position of the floating drilling equipment Drilling equipment testing equipment capable of performing testing on drilling equipment And a method thereof.

As the international phenomenon of industrialization and industry develops, the use of resources such as petroleum is gradually increasing, and thus the stable production and supply of oil is becoming a very important issue on a global scale.

For this reason, the development of the marginal field or deep-sea oil field, which had been neglected due to economic difficulties, has become economic in recent years. Therefore, along with the development of seabed mining technology, drilling rigs with drilling facilities suitable for the development of such oilfields have been developed.

Conventional submarine drilling has been mainly used as a fixed platform for drilling at one point in the offshore area. Recently, floating drilling facility capable of drilling in depths of 3,000m or more has been developed and used for deep sea drilling.

These drilling facilities are equipped with various drilling equipments such as derrick system, riser, drill string and so on to drill oil and gas existing under the sea floor.

In recent years, the development of deep-sea oil fields has been actively promoted, so safety of various drilling equipments is especially important. Among the drilling equipments, the most relevant equipment for drilling is BOP (Blow out Preventer, Prevention device).

BOP equipment is installed to prevent the gas explosion of submarine wells by safely removing high pressure gas generated during drilling process and connected to the upper wellhead of submarine oil well through a riser from marine drilling facility .

These BOP equipment is designed to withstand deep sea conditions and withstand pressures up to 15,000 psi in high pressure environments above 3,000 m (4,300 psi) depth. However, since the test is not performed in the actual environment until it is installed in the actual deep water well, various problems arise in actual installation work.

Generally, the test for the BOP equipment is partially tested by applying external pressure or internal pressure separately to each part constituting the BOP equipment, and there is no device capable of performing such a test in the fully assembled state As a state, there is a desperate need for a device capable of performing various types of testing under the same conditions as the actual environment.

In this case, the equipment to be tested may be a device used in a deep sea environment, for example, a BOP equipment 200 that is latched to the upper well head of a seabed well to prevent internal gas explosion of the seabed well can be applied . Hereinafter, for convenience of explanation, the case where the BOP equipment 200 is applied as the equipment to be tested will be described as an example.

The pressure vessel 100 may be formed in the form of a container having various shapes in which a test chamber C is formed. It is preferable that the pressure vessel 100 is formed in a cylindrical shape in consideration of the supporting strength against the internal pressure of the pressure vessel 100 . In addition, the pressure vessel 100 may be configured in such a manner that it is connected to a negative electrode power source for corrosion prevention.

At this time, if a too high pressure is formed in the internal space of the test well head 300 or the internal flow path of the internal pressure connection line 520, a separate pressure safety device may be provided to adjust the pressure. For example, A separate relief valve 401 may be mounted on the pressure connection line 520 as shown in FIG.
