This technical scheme this arrangement has improved cabin bottom space utilization effectively.

Preferably, the marine host base structure further includes a strong rib plate, and the strong rib plate is disposed between the first strong longitudinal girder and the second strong longitudinal girder; a plurality of bolt holes are formed in the host base; the strong rib plate is provided with an operation hole corresponding to the position of the bolt hole.

This technical scheme can make things convenient for the construction of host computer base fastening bolt.

Preferably, marine host computer base structure still includes the middle part diaphragm, the middle part diaphragm set up in the below of bottom plate, middle part diaphragm, two first strong vertical trusses, bottom plate form host computer lubricating oil circulation cabin.

Preferably, the middle transverse plate, the two first strong longitudinal girders and the bottom of the ship body form a second isolated empty cabin.

This technical scheme this arrangement improves cabin bottom space utilization effectively.

The invention also provides a ship comprising the marine main engine base structure.

Preferably, the host pit and the host base extend from the bow to the stern, the number of the host bases is two, and the two host bases are arranged in parallel.

This technical scheme is favorable to the host computer to install the stability on the host computer base.

Preferably, the vessel further comprises a cargo hold inner bottom platform located closer to the bow of the vessel than the main machine base structure, the main machine base structure being smoothly connected with the cargo hold inner bottom platform.

According to the technical scheme, the smooth connection can improve the fatigue resistance of the corners of the cabin in the cargo hold and reduce the occurrence of cracks.

The positive progress effects of the invention are as follows: 1. the integrated design has wider application range. 2. Effectively improve the utilization rate of the bottom space of the engine room. 3. The structural strength and rigidity of the host base area is better. 4. The structure is arranged standardly, reduces the design degree of difficulty, reduces structural component. 5.
