Embodiment Construction

[0019] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0020] The present embodiment provides a submersible moonpool installation process, comprising the following steps:

[0021] Step 1: To determine the baseline, use the total station to draw out the midship line of the hull and the center point of the moon pool on the main deck, and at the same time determine the center point of the moon pool on the screen edge of the bottom plate, and use a tape measure to check the center point of the moon pool. The distance from the midship line of the hull is required to be within ±1mm. After confirmation, proofing and punching points are made at the deck position, and make a record. At the same time, draw the reference lines P1...

Abstract

The invention discloses a diving moon pool installation process. The overall moon pool installation is completed through the installation of the track under the main deck and the installation of the moon pool part on the main deck, so as to simplify the installation process and reduce the difficulty of construction. The installation of the track under the main deck and the installation of the moon pool on the main deck are separately inspected on both sides, which is easy to install and control, and improves the effect of installation.

Description

technical field [0001] The invention relates to the technical field of ships and marine engineering, in particular to a submersible moon pond installation process. Background technique [0002] In the field of ship and marine engineering, according to the operational or functional requirements of ships and marine structures such as drilling ships, engineering auxiliary ships of pipe-laying ships, etc., a vertical penetration of the hull, with free liquid surface in the cavity, inside and outside, will be arranged on the hull. The structure of the submersible moon pond connected by sea water, but the installation operation of the existing submersible moon pond is more complicated, the construction is more difficult, and the cost is high. Therefore, it is particularly important to solve this type of problem. SUMMARY OF THE INVENTION [0003] In view of the above problems, the present invention provides a submersible moon pond installation process, which can quickly and conve...
