Multifunctional outward-turning side port for natural gas station of dual-fuel ultra-large container ship

Abstract

The invention provides a multifunctional outward-turning side port for a natural gas station of a dual-fuel ultra-large container ship, and relates to the technical field of ultra-large container ships. The multifunctional outward-turning side port comprises an upper side port which is arranged at an opening of a ship body outer plate and is parallel to the ship body outer plate when an upper cabin door is in an open state; a lower side port which is arranged at the opening of the ship body outer plate and is perpendicular to the ship body outer plate when being in an open state; at least onesaddle connected with a lower cabin door; a water curtain pipe embedded in the lower cabin door; a first supporting device connected with the upper side port and a driving device and used for retracting, releasing and locking the upper side port under the driving action of the driving device; a second supporting device connected with the lower side port and the driving device and used for retracting, releasing and locking the lower side port under the driving action of the driving device; and a control device connected with the driving device and used for controlling the driving device to actso as to realize retracting unfolding and locking of the upper cabin door and the lower cabin door. The port has four purposes, so that the construction cost is saved; requirements of dangerous areasare met, and operation is convenient.

Description

Technical field [0001] The invention relates to the technical field of ultra-large container ships, in particular to a multi-functional overturn side door used for a dual-fuel ultra-large container ship gas station. Background technique [0002] At present, ultra-large container ships use LNG (liquefied natural gas) as their main fuel, and LNG (liquefied natural gas) filling stations need to be arranged on board. Considering factors such as the distribution of dangerous areas, layout space, and operation of refueling hoses, it is a better plan for dual-fuel ultra-large container ships to arrange refueling stations on the second deck, and they are arranged in the side cabin area of ​​the hull structure and on the hull shell. The upper opening means that the gas station is located in a semi-enclosed area. [0003] Due to the limitation of the longitudinal bulkhead structure of the side tank, the lateral space of the gas filling station is the width of the side tank. After the releva...

Problems solved by technology

For example, according to the conventional water curtain arrangement method, since the lower port door is in a horizontal state when it is opened, the water curtain is blocked by the lower port door, and cannot isolate the LNG hose and the hull plating
