LNG fuel water refueling device

Abstract

The invention relates to the technical field of water refueling, in particular to an LNG fuel water refueling device. The LNG fuel water refueling device comprises a ship unloading module, a vehicle unloading module, an LNG fuel storage module, a gas supply module and an immersed pump module which are arranged on a wharf boat; the ship unloading module and the vehicle unloading module are separately provided with refueled pipelines connected to a transport ship and a carrier vehicle; the ship unloading module and the vehicle unloading module are connected to the LNG fuel storage module throughtransport pipelines; the LNG fuel storage module is separately connected to the immersed pump module and the gas supply module through transport pipelines; and a gas output pipeline connected to thegas equipment wharf boat is arranged on the gas supply module. The carrier vehicle, the transport ship and a power ship are connected through standard connecting pieces, so that the water LNG refueling device can be constructed conveniently and flexibly.

Description

technical field [0001] The invention relates to the technical field of overwater filling, in particular to an overwater filling device for LNG fuel. Background technique [0002] Based on environmental protection and water resources protection, driven by relevant national policies and measures, the use of LNG fuel for inland ships has gradually formed a scale, and LNG fuel replenishment (filling) for transport ships is a bottleneck problem that needs to be solved urgently. [0003] At this stage, most inland LNG fuel supply devices (ships) are built on a single ship, and the refueling devices mainly rely on transplantation and transformation of related equipment and products on land. When filling, it is necessary to temporarily build equipment and connect various components through pipelines. The workload is huge, and because the components are scattered, the construction work is complicated, which is not only a waste of time, but also prone to errors. In addition, land-bas...

AI Technical Summary

Problems solved by technology

When filling, it is necessary to temporarily build equipment and connect various components through pipelines. The workload is huge, and due to the scattered components, the construction work is complicated, which is not only a waste of time, but also prone to errors

In addition, land-based equipment is usually larger in size due to limited site constraints, while ship equipment has limited layout space, and copying land-based equipment is often not suitable for the narrow space of ships.

Moreover, the safety protection of land equipment is relatively easy to solve. Ship equipment must strictly limit the scope of dangerous areas and meet the requirements of the regulations. The reliability requirements of ship equipment are higher than those of land equipment. In fact, in terms of time, space or safety, it cannot better meet the refilling requirements.
