Treatment methods for ro-ro ship moorings adjacent to dangerous areas

Abstract

The invention discloses a method for treating dangerous areas adjacent to mooring equipment of ro-ro ships. The above entrances and exits; only one airtight self-closing door is installed at each entrance; step 2, limit switches are set on the airtight self-closing doors; sound and light alarms are set on the partition bulkheads, and the sound and light alarms are connected to the limit switches ;When the airtight self-closing door is in the open state, the limit switch will trigger the sound and light alarm and send out the sound and light alarm signal; when the airtight self-closing door is closed, the limit switch will cut off the power supply of the sound and light alarm , the alarm is stopped; step 3, a warning sign is set on the airtight self-closing door, and warning words are arranged on the warning sign. The invention can exempt the mooring area from being a safe area, so the mooring electrical equipment does not need to be of an explosion-proof type, the crew can easily enter and exit the mooring area, and the construction cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a processing method for a ro-ro ship mooring equipment adjacent to a dangerous area. Background technique [0002] For some train ro-ro ships, the stern mooring area is generally arranged on the starboard and starboard sides of the stern of the ship, and is often adjacent to the ro-ro space of the cargo hold. The ro-ro space is generally loaded with dangerous goods and belongs to the dangerous area; Dangerous areas that are directly connected or connected through openings are also dangerous areas. Ordinary mooring electrical equipment cannot be directly used in dangerous areas, and corresponding measures need to be taken. [0003] There are generally two solutions now: [0004] Option 1: The mooring equipment selects mooring electrical equipment that meets the corresponding explosion-proof level, and can be directly arranged in the dangerous area. The disadvantage of this scheme ...

AI Technical Summary

Problems solved by technology

The defect of this scheme is: an air lock device is installed between the ro-ro area and the mooring area. On the one hand, the air lock device requires the installation of two airtight self-closing doors, which is inconvenient for the crew to enter and exit the mooring area, and the shipowner does not accept it; On the other hand, two doors increase the construction cost of the shipyard
