Abstract

The present invention relates to a porthole manhole for preventing flooding of mooring support vessels, and more specifically to the porthole manhole for preventing flooding of mooring support vessels in which a number of manholes with portholes facing an internal compartment are installed on the mooring support vessel, thereby allowing the compartment to be inspected from the outside at all times. In an event of water leakage or oil leakage inside the compartment, a warning is sent to the outside through a water level sensor and an alarm device detecting the same so that rapid response can be executed.

Description

Porthole manhole for prevention of flooding of mooring support boats}

The present invention relates to a porthole manhole related to a mooring support vessel, by installing a side window manhole for constant confirmation of the inside and outside of the mooring support vessel, resulting in unrecognizable fine holes in the hull, etc., and leakage and leakage of various internal facilities and piping facilities It is to implement a safety system that can prevent accidents such as flooding, sinking, and sinking in advance.

Mooring support boats (YPK), which are currently in operation in various forms, are inspecting the interior and exterior compartments through the opening of manholes.

Therefore, it is impossible to recognize in advance when the hull rupture in the compartment and various piping initial leaks and oil leaks occur, (it is possible to check only part of the interior during the daytime through the opening of the manhole, but it is impossible to check at night). It cannot be confirmed until a slope of more than 1/3 occurs.

The total number of these manholes is 699 (about 24 nuts fastened at 1 location, 16,776 nuts, about 13 manholes per ship), and due to excessive inspection time, actual internal inspection is not possible and daily inspection is also limited. . (It takes at least 18 minutes and 50 seconds to inspect one manhole, and it takes about 4 hours per ship.)

In addition, the internal compartments of these mooring support boats are operated with restricted compartments provided on the port side, starboard side, and center. In case of leakage or leakage of oil in the central independent compartment, visual confirmation is not possible. this is impossible

In the past three years, there have been many safety accidents and losses, such as leakage of oil inside the mooring support vessel, flooding due to leakage, and subsidence.

Accordingly, the development of a device capable of solving these problems is urgently emerging.
