Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
As shown in fig. 1-3, the present embodiment provides an ocean platform including a platform body 100 and a draft reading device. The draft reading device is located inside the platform body 100 and includes the pipe 1. The upper end of pipeline 1 is opened, and the lower extreme communicates in platform body 100's sea water door 21, and pipeline 1 has the first pipeline section 11 that is located sea water door 21 top, and first pipeline section 11 is the hyaline tube. The offshore platform in the embodiment is an offshore oil 981 deepwater semi-submersible drilling platform.
Through such structure, utilized the linker principle, in the in-service use process, lie in sea level 200 the same height with first pipeline section 11 setting to introduce transparent first pipeline section 11 with the sea water in the platform outside through the sea water door, make and to show sea level 200's actual height on first pipeline section, in order to reach the purpose of observing draft height in the platform inside, reduce survey crew's work risk, improve measurement accuracy simultaneously.
Meanwhile, the draft reading device is simple in structure, and the seawater door 21 arranged on the ocean platform is communicated with external seawater by the draft reading device, so that the integral draft reading device is convenient and quick to assemble and disassemble.
An air check valve 23 is provided in the chamber 22 inside the sea door 21, and the air check valve 23 is connected to the outside sea water through the sea door 21, and its own valve is easily opened or closed. The draft reading device in this embodiment has the duct 1 connected to the opening on the inside of the air check valve 23, and by opening the air check valve 23, the seawater door 21 is opened and the seawater flows into the chamber 22 and enters the duct 1. After the reading of the draft reading is completed, the pipeline 1 may be dismantled after the air check valve 23 is closed to avoid leakage of seawater to the interior of the ocean platform.
In this embodiment, first pipeline section 11 passes through welded fastening in platform's 3 surfaces of stand, also can use modes such as buckle or limiting plate to fix first pipeline section 11 in fact. The surface of the upright post 3 is provided with scale marks 31, and the scale marks 31 correspond to the draught. Of course, in other embodiments, graduation marks 31 may also be provided on the transparent first pipe section 11, to likewise achieve the purpose of accurately reading the draft height.
By providing the graduation marks 31, the liquid level in the first pipe section 11 can be aligned with the corresponding graduation marks 31, so that a measurer can accurately and conveniently read the liquid level.
In this embodiment, the second pipeline section 12 is further provided between the first pipeline section 11 and the sea water gate 21, the second pipeline section 12 is a hose, and both ends of the hose are fixed by a clamp to ensure water tightness. The hose has the advantage of convenient assembly and disassembly, and can avoid the damage caused by collision. Thus, in actual use, the first pipe section 11 can remain fixed to the surface of the column 3 of the ocean platform, and when the draft reading device is not needed, only the second pipe section 12, which is a hose, needs to be removed. At this time, the sea gate 21 may be used for another purpose.
Of course, in other embodiments, the second pipe section 12 between the first pipe section 11 and the sea water gate 21 may be a hard pipe, the first pipe section 11 is connected to the second pipe section 12 through a valve such as a ball valve to improve water tightness and reliability, and the inflow of sea water is controlled by opening and closing the ball valve, and the second pipe section 12 should be fixed on the surface of the pillar 3. The hard pipe is safer than the hose in the underwater high-pressure environment, and the connection of valves such as a ball valve and the like is more reliable than the connection of a clamp.
11 upper portions of first pipeline section should still be equipped with the extension section that length is no less than 5m to guarantee that the sea water can remain in first pipeline section 11 all the time, and can not spill over from the upper end of first pipeline section 11, and then guarantee the holistic security of device. Wherein, since the upper end of the first pipe section 11 must be open, in order to ensure that the seawater will not flow into the hull in any case, a safe length much greater than 5m is used in this embodiment.
As shown in fig. 4, the embodiment further provides a draft reading method for an ocean platform, including:
step S1: arranging a pipeline inside the ocean platform, wherein the lower end of the pipeline is communicated with a seawater door of the ocean platform, the upper end of the pipeline is open and higher than the maximum draught height of the ocean platform, and the pipeline part of the pipeline, which is positioned near the sea level, is a transparent pipe;
step S2: the sea water level in the transparent tube is recorded.
In this embodiment, the transparent tube is arranged as the first tube section 11 in fig. 1 and 2. By the method, the sea level outside the ocean platform is introduced into the transparent pipe by utilizing the principle of the communicating vessel, so that the purpose of observing the draft height inside the ocean platform is achieved, the working risk of measuring personnel is reduced, and the measuring precision is improved.
Step S2 further includes: recording the maximum value and the minimum value of the sea water level height in the transparent pipe according to the scales in a detection period, wherein the detection period can be one or more.
The method for reading the draft of the ocean platform further comprises the step S3: and calculating the average value of the maximum value and the minimum value of the obtained sea water liquid level height to obtain the accurate actual draft height.
In this embodiment, the influence of the waves on the sea surface on the readings can be reduced by using the above method. For multiple sets of measured values, statistical methods may be used for data processing. In the embodiment, for a plurality of groups of measured values, after a maximum value and a minimum value are removed, the average value is calculated, the influence caused by abnormal values in accidental situations is eliminated, and the measurement precision and stability are improved.
