Description

The present invention relates to a living quarter structure of a ship and an offshore floating structure such as a floating production storage and shipping facility (FPSO) and a floating storage and shipping facility (FSO).

Conventionally, in order to shorten the construction period and design period of ships and floating offshore structures (for example, FPSO, FSO), a method of manufacturing a living area and a hull in different yards and mounting the completed living area on the hull has been known. ing. In addition, in offshore floating structures such as FPSO and FSO, the hull manufacturing yard and the integration yard where production equipment is mounted on the hull are usually different, but the living quarters are also manufactured in a yard different from the hull manufacturing yard, and in the integration yard. It may be mounted on the hull together with production equipment.

When the residential area manufacturing yard is different from the hull manufacturing yard and the integration yard in this way, the following problems occur. In other words, since the piping and wiring connecting the cargo area or production equipment and the engine room are usually configured to pass through the living quarters, piping and wiring work should be done only after the living quarters are mounted on the hull. Therefore, the installation work of the residential area affects the construction period of the ship or the offshore floating structure. In addition, since touch-up work is required for back burning after welding, the heat insulation work for the uppermost ceiling in the engine room cannot be completed until the residential area is installed, so the residential area will be installed instead of the hull manufacturing yard. It must be done in the integration yard, which, like the plumbing and wiring work, causes the construction period of ships or offshore floating structures to be prolonged.

The present invention allows the construction of the living quarters and the hull to be completed in the living quarters manufacturing yard or the hull manufacturing yard, respectively, thereby increasing the amount of work that can be performed in parallel in the living quarters manufacturing yard and the hull manufacturing yard. , The purpose is to shorten the construction period of ships or offshore floating structures.

The piping joints of the pipes and electric wires connected to the engine room and the relay box of the electric wires on the engine room side may be configured to protrude from the upper deck into the first piping / wiring section. In this configuration, for example, in the first piping / wiring section, the pipes connected to the plurality of residential area side piping joints are combined into one and connected to a single engine room side piping joint. Preferably, the number of engine room side piping joints is smaller than the number of living quarter side piping joints.

Preferably, the side wall of the first piping / wiring section is divided into an upper plate member and a lower plate member by a connecting portion extending in the horizontal direction, and the upper plate member is a plate member on the extension of the side wall of the living area and resides. Manufactured with the section, the lower plate member is attached to the upper deck.

A soundproofing material or a vibration-proofing material may be provided in the first piping / wiring section.

A passage deck may be provided on the side of the residential area, and the height of the passage deck may be the same as that of the first layer of the residential area. In this case, a second piping / wiring section for providing piping and / or electric wires may be formed between the passage deck and the upper deck.

An access space may be formed between the side wall and the partition wall by providing the partition wall inside the side wall of the residential area on the first layer of the residential area. Further, a storage chamber may be provided between the first piping / wiring section and the upper deck.

Therefore, according to the present embodiment, various operations in the first piping / wiring section 41, that is, welding or backburn repair work for the connection portion 44, and connection work for the pipes 37, 56 and the electric wire 32 in the section have a degree of freedom. Is expensive and can be done easily. Further, since the degree of freedom of the connection position is high, the living area 20 and the engine room 11 can be designed without being bound by the mutual arrangement, and it is easy to standardize the respective arrangements. The height of the first piping / wiring section 41 is preferably 1200 mm or more at the lowest point in consideration of the presence of workers in the work.

On the other hand, in the present embodiment, since the residential area 20 is provided so as to be separated from the upper deck 13, a passage deck 22 and stairs (or slopes) 24 and 25 are required for entering and exiting the residential area 20. , The lower side of the passage deck 22 can be used as the second piping / wiring section 42. Therefore, it is not necessary to install the piping under the outer wall of the living area 20 or the overhanging deck, and the piping work can be completed in the hull manufacturing yard.
