DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading arm for a liquid or gas handling apparatus having a cover for preventing scattering of oil or the like (hereinafter referred to as a cover for preventing scattering).

[0002]

2. Description of the Related Art FIG. Emergency detachable device
An ordinary loading arm not equipped with this device (hereinafter referred to as ERS) is not commonly equipped with a cover for preventing oil leakage and scattering.

Also, Rodin equipped with ERS
Most of grayed arm is also fact is preventive cover leakage oil scattering is not provided. Some ERS-equipped loading arms provided with a cover for preventing oil leakage also have a skirt-shaped cover that covers only the ERS as shown in FIG. At present, the only consideration is to receive the oil leaking down with an oil pan or the like.

Therefore, in the conventional method, if any trouble occurs in the ERS part or a large amount of oil leaks due to a trouble in the connection portion of the manifold flange, a serious accident of marine pollution occurs. It will cause great social problems and losses.

[0005]

In order to solve the conventional problems, the ERS should be covered with a cover having a shape that completely covers from the upper part of the ERS to the connection part of the manifold flange, so as to be prepared in case of an oil leak or the like. is necessary.

However, if a cover is formed so as to cover the entirety, the following disadvantages appear. (1) Since the entire cover becomes large and the cover becomes heavy, it is difficult to remove or attach the cover. (2) The cover itself loses its shape due to its own weight, which impairs the function of the cover and lowers its commercial value. (3) The connection work between the loading arm and the manifold flange is hindered. (4) When connecting the loading arm to the manifold flange, the removal of the ERS safety device is hindered. (5) If the entire cover is made of a transparent material for inspection inside the pumping operation, oil resistance, liquid resistance, weather resistance, strength,
There is a problem in production.

[0007] If the material is supplemented, the cover becomes an opaque cover, and it becomes impossible to inspect the inside during the oiling operation. (6) If you just cover the whole, you will not be able to follow the movement of the loading arm when disconnecting the ERS,
The cover will be damaged. An object of the present invention is to provide a loading arm that can solve such a problem.

The central part of the cover 1 for preventing oil splatters is ER
The assumption that the ERS has been disconnected by the operation of the S, Russia
It has been in the bellows structure to be able to follow the some of the movement of over loading arm.

[0022] Thus, the leakage oil shatterproof cover 1 b
And consideration so as not to be damaged by the movement of over loading arm. In addition, the present invention can be applied to a cover for preventing oil leakage and scattering having a cylindrical shape or an elliptical column shape having the same function, in addition to the shapes described in FIGS.

[0023]

Since the apparatus according to the present invention is constructed as described above, it has the following effects. (1) By covering the entire connection portion between the ship and the ship where oil leakage is most likely to occur in the loading arm with the oil leakage scattering prevention cover, marine pollution due to oil leakage can be prevented. (2) Even if a large amount of oil leaks from the connection of the ERS or the manifold flange, the oil leaks through the ship-side oil recovery pipe line connected to the discharge port provided at the lower part of the oil leakage prevention cover. Returning to the tank on the ship side, it is possible to prevent oil leakage to the sea. (3) It is possible to confirm whether there is any abnormality in the ERS or the connection portion of the manifold flange during the oil lifting work, through the inspection window of the oil leakage scattering prevention cover. (4) Opening and closing the fasteners provided on the oil leakage scattering prevention cover allows the manifold flange connection work and E
RS safety device release work can be done easily. (5) The oil leakage prevention cover has a structure that can be mounted on the loading arm even when the loading arm is in the retracted state, so that the work of attaching and detaching the oil leakage prevention cover can be omitted, and work efficiency can be improved. Can be done. (6) Due to the bellows structure of the oil leakage scattering prevention cover,
Even if the RS is activated, the bellows is extended by a necessary length, so that damage to the oil leakage scattering prevention cover can be prevented. (7) The mounting frame of the oil spill-prevention cover provided on the upper part of the oil spill-prevention cover can prevent the collapse of the shape and maintain the aesthetic appearance.
