[Abstract]:
A shipyard in the process of opening up overseas markets, foreign shipowners to buy a more advanced performance of the diving bell, so the diving bells on the track and the installation of lifting pul

  Background of the project:

  A shipyard in the process of opening up overseas markets, foreign shipowners to buy a more advanced performance of the diving bell, so the diving bells on the track and the installation of lifting pulleys put forward higher requirements. The traditional method can not meet the accuracy of the measurement operation needs, and the use of laser tracker, while ensuring the measurement accuracy, but also greatly enhance the efficiency of the measurement operation.

  The person in charge of the diving clock measurement project told us that they did not understand the laser tracker before they were in the traditional way: the theodolite, the ruler, not only inefficient but also a lot of manpower and material resources.

  Difficult to measure:

  First, the measurement space:

  The coordinate system of the whole diving chamber is composed of three faces, namely horizontal datum plane, transverse datum plane and longitudinal datum plane, and the reference holes of these faces are located on the bottom plate and steel structure respectively. In the measurement process, The reference hole, the diving bell track and the hoisting pulley must be completed by the frame. And by the laser tracker measurement principle of the restrictions, these obstacles to the entire measurement process to add a lot of trouble.

  Second, the measurement environment:

  The entire cabin temperature is very high, very few places of ventilation, and the whole ship is at the beach, sooner or later the temperature difference, as well as real-time swing, which also increased the measurement difficulty.

  Solution:

  As the API laser tracker compact and convenient, easy to move, accuracy and stability of outstanding performance, to solve the problem of small space. API application engineers in the measurement process set a number of reference points, on the one hand to facilitate the laser tracker fought; the other hand can be monitored due to vibration and human factors caused by changes in instrument position. Coupled with the tracker's own environmental monitoring system, the environmental factors caused by the loss of precision to a minimum.

  The traditional measurement method is to measure and then adjust, and then measure, time-consuming and laborious. Now, through the powerful dynamic performance of the API laser tracker, engineers can adjust the track according to the value of the computer screen, while improving the efficiency, but also save the manpower and material resources.

  At the same time, in the measurement process, API service team can also be based on different on-site environment, measurement needs and accuracy needs, to provide different measurement methods. It is worth mentioning that: due to the establishment of the benchmark position is like punching, the target can not be directly measured, API engineers through the use of rich measurement accessories (such as point measuring seat) and can easily measure the hidden point of the Intelliprobe360 smart probe (Or vProbe wireless smart probe), to solve the hidden point of the measurement problem.

  Summary:

  In the API engineer's efforts with the shipyard staff with the active cooperation, the past need more than half a month or even a month to complete the measurement task, just a week to successfully passed the acceptance of the owner.
