Description

Floating structure employed in integrated plant for bottom cleaning {FLOATING STRUCTURE ADOPTED IN INTEGRATED PLANT FOR CLEANING SHIP HULL SURFACE}

The present invention relates to a floating structure employed in a ship-bottom cleaning integrated plant, and specifically, various foreign substances and aquatic organisms removed after cleaning the ship-bottom are recovered and then treated with water to remove the pollutants and then discharged to seawater to prevent the ecosystem from being disturbed It relates to a floating structure employed in a bottom cleaning integrated plant that enables

In general, since a ship is operated in a state where the lower part of the hull is submerged in seawater, foreign substances such as various contaminants or various aquatic organisms such as water moss and barnacles may be attached to the bottom or side surface located in the water.

As such, various foreign substances and aquatic organisms attached to the hull not only damage the appearance of the ship, but also act as a resistance when the ship is operating and become a factor that lowers the speed of the ship, thus greatly increasing the fuel consumption of the ship. It is very important to periodically clean various foreign substances and aquatic organisms attached to the surface.

In the prior art, the cleaning of the hull exterior was carried out by a diver directly to clean the foreign substances and aquatic organisms attached to the exterior surface of the hull. There is a problem that it is impossible to clean in severe places.

In particular, in the case of large ships, as the amount of cleaning work increases, the time spent in the water becomes longer, which poses a lot of risk to the diver, and by performing the cleaning work depending on the view of the diver, the cleaning quality of the deep bottom of the ship is significantly lowered.

In addition, there are cases where a ship is lifted offshore and cleaned, but it is impossible for a large ship to be lifted onshore. There is a problem that occurs.

In addition, recently, a bottom cleaning robot that runs while attached to the outer surface of the hull and performs a cleaning operation with a brush or the like has been used.

However, it takes a lot of time to clean every nook and cranny of the hull using a small-scale bottom cleaning robot, and it is impossible to clean an area formed in a complex shape including the stern of the hull provided with a propeller and a rudder.

Therefore, as described above, since a diver still has to directly perform a cleaning operation for an area formed in a complex shape, there is a problem that a lot of time and difficulty follow.

In addition, the conventional bottom cleaning robot cannot completely suck and remove foreign substances and aquatic organisms including antifouling paint that fall off from the outer surface of the hull during the hull cleaning process. In this case, there is a problem of causing disturbance to the surrounding marine ecosystem due to the alien aquatic life entering the water during the cleaning process by attaching the foreign aquatic life to the outer surface of the hull.

Vessel adherents refer to marine organisms such as seaweed, tubeworm, moss, slime, biofilm, and calcareous fouling, barnacles on the outer surface of the lower part of the ship.

[Economic loss due to anchoring organisms]

Vessel adherent organisms increase the skin friction drag during ship operation and are one of the major causes of reduced fuel efficiency of ships.

According to the US Navy's announcement, it is analyzed that barnacles are generated extensively in the hull, requiring up to 86% of additional engine power at a speed of 15 knots.

MAERSK, the world's best shipping company, is reducing fuel by 5% by removing about 40% of berthing organisms from ships.

In addition, turbulence/cavitation occurs due to the anchoring organisms, which causes a problem of lowering the measurement accuracy of various sensors such as sonar and speed sensor.

As expensive low-sulfur oil is used as a fuel for ships according to the IMO's emission regulations, the problem of fuel efficiency reduction for shipping companies is recognized as a very important factor.

[Environmental loss due to anchoring organisms]

Birth anchorage is pointed out as the representative cause of the movement and inflow of foreign marine life along with ballast water.

In 2011, the 65th Marine Environment Protection Committee (MEPC) adopted and approved management guidelines for minimizing the migration of marine organisms, and supplemented and additional investigations were conducted at the 72nd, 73rd, and 74th meetings.

The IMO is contemplating a way to regulate berthing organisms according to experts' claims that hull anchoring organisms have more than twice as much impact as the disturbance of the marine ecosystem by ballast water.

The IMO has decided to revise the “Guideline for Control and Management of Vessels Attached to Ships” to prevent the introduction of alien species and protect the marine environment.

Based on the above, the trends related to regulations related to veneers in each country are as follows.

- Australia: As a plan to preemptively respond to IMO regulations, from September 2020, vessels entering ports in their country will be required to clean their hulls within 30 days before entering port.

- California, USA: Mandatory submission of biofouling management plans and reports for ships of 300 tons or more after January 2018

- New Zealand: In fact, there was a case in which a ship trying to enter New Zealand was refused entry last year and entered the port after cleaning the hull in Indonesia.

- Indonesia: Significant increase in the number of hull cleaning at repair shipyards, etc.

[IMO Biofouling Management Trend]

IMO is making an effort to reduce marine organisms through the adoption of the International Convention on the Regulation of the Use of Harmful Antifouling Systems by Ships (AFS Convention) in 2001.

The AFS Convention went into effect in 2008 for more than 25 countries that account for more than 25% of the world's gross tonnage, and as of 2020, 89 countries including China, Japan, Russia, and the United States have signed up as Parties to the Convention.

IMO, going beyond the initial ship antifouling system level management, recognized the importance of a management system to reduce the ecological and economic damage of biofouling, and, through the Marine Environment Protection Committee (MEPC) under IMO, in 2011, ' was adopted.

The 'Guideline for Vessel Attachment Organs' recommended that ships keep the 'Biofouling Management Plan' and 'Biofouling Record Book' as measures to minimize the inflow of biofouling.

[Biofouling Record Book]

- Record of all inspections to be performed on the vessel and biofouling management procedures

- It is recommended that the Biofouling Record Book be maintained for the lifetime of the vessel.

- Applied antifouling paint operation information, dry docking operation information, underwater inspection measures, and abnormal operation details other than the normal operation profile of the vessel should be included.
