Description

LNG transport ship for inland water area

Technical Field

The invention belongs to the technical field of ship construction, and particularly relates to an LNG transport ship for inland water areas.

Background

As the main artery of inland navigation in China, the annual transportation quantity in Changjiang river reaches 30 hundred million tons, which accounts for more than 60% of the total inland navigation. However, the conventional fuel such as diesel oil, heavy oil and the like is used as the ship power fuel for long-term voyage, and compared with the ship using LNG as the fuel, the comprehensive pollution emission of the conventional fuel ship is higher by 70%.

Factors influencing ship driving vision mainly include cab height, captain, deck room, equipment and the like. The conventional inland LNG ship is mostly of a rear-mounted type, i.e., the superstructure and the cab are disposed above and behind the main hull where the LNG cargo tanks are located. However, the inland ships need to cross a plurality of Yangtze river bridges along the Yangtze river, and the height of the ship body and the height of the superstructure are limited to a certain extent. And the cargo transported by the ship has large volume, small density, high ship body dryness and various rooms, platforms, equipment, pipelines and cables on the deck. So the traditional inland LNG ship is expected to simultaneously meet the difficulties of good cab visual field (high cab height), long ship length (long cargo hold, large loading capacity) and sufficient deck space (convenient arrangement and simple construction).

Further, a cargo mechanical chamber is arranged on the upper deck surface where the cargo tank module is located.

Further, the cargo transported in the first cargo tank, the second cargo tank, and the third cargo tank in the cargo tank module includes LNG, LPG, liquid ammonia, and liquid hydrogen.

Further, the superstructure comprises a plurality of decks including an a deck, a B deck, a pilot deck, and a compass deck.

Based on the technical scheme, the LNG carrier for inland water areas has the following technical advantages through practical application:

1. according to the LNG transport ship for the inland water area, provided by the invention, the influence of a ship length on a driving sight is avoided by adopting the mode that the cab, the engine room and the steering engine are arranged between the engine room and the ship bow, the extent of the front view of the cab is increased, the blind area range of the driving sight caused by the length of the cargo hold in the ship bow direction is reduced, and the available space of a deck is increased.

2. According to the LNG carrier for the inland water area, the length of the cargo hold is increased by leading the cab, the engine room and the steering engine to the bow, the liquid cargo hold can be arranged at the stern of the LNG carrier, and the three liquid cargo holds are arranged on the LNG carrier, so that the number of the cargo holds is increased, the loading capacity of LNG is increased, and the economical efficiency of the inland LNG carrier is improved.
