Drydocks and their diversity

A dam is a structure that is built to contain water, preventing its passage. This is a depot used for the construction, repair and maintenance of boats, ships and other vessels. The dock can be flooded to allow the ship to float and then the water can be reduced, so that the ship rests on a support platform, where it can be worked on. Flygt pumps provide flexible and reliable liquid treatment solutions for dewatering these docks.

When emptying the dry dock, the boats must be lowered so that they are properly be supported on the platform. The less time it takes to get the dock empty, the higher the production of ships. Naturally, this need must be balanced with the need for a slow and safe settling of the ship in a dry state.

 

They can be built perpendicular or parallel to the watercourse that it is intended to contain.

Depending on the dry setting system used, we can highlight:

  • Boathouse: it is the most primitive system; it is currently used for smaller boats of little size. It consists of an inclined plane on which the object to be lifted moves by means of sleds.
  • Dry dock: it is a lock where the vessel is introduced and once closed, the water is pumped from the interior until the vessel is supported on a bed or riding hall, which must "copy" the geometry of the hull to keep it stable.
  • Floating dock: this is a naval device that uses the principle of operation of submarines: by flooding tanks, it sinks the structure to allow the vessel to be repaired to enter it. Once in place, these tanks are made smaller, causing the assembly to rise, thus achieving the dry setting.
  • Sincrolift: it is a system of articulated beams hoisted by winches at their ends, each one operated by a powerful electric motor. The set of motors operates synchronously, generating a large lifting platform. First, the platform is equipped with a bed or riding hall similar to the case of the dry dock but mounted on rails; second, the assembly is submerged so that the ship to be raised is on the aforementioned bed; third, the ship is raised (which remains "anchored "in bed) and finally travels on the rails, leaving the elevator free to continue operating.

 

The dry dock is part of the facilities of a shipyard regardless of its main activity, it could be the construction or repair of ships. To carry out these construction and repair works, the shipyard also has its own dock with additional equipment such as cranes, facilities such as docks and workshops that make the repair or construction of a ship possible.

10 curious facts about maritime transport

1. Maritime transport represents 90% of world trade shipments.




2. The cost of building large container ships can exceed $ 200 million.




3. Only between 2% and 10% of the containers that transit around the world are inspected.




4. Maritime transport is an ecological form of transport, if we compare it with trucks or airplanes.




5. The average cost of shipping a bicycle is $ 10. The cost of sending a can of soda is $ 0.01.




6. Right now, there are about 20 million containers traveling by sea.




7. The engine of a container ship is 1,000 times more powerful than that of a car.




8. About two-thirds of commercial ships do not have advanced communication facilities on the high seas. Only 10% of the boats have Internet on board.




9. The ports of the East Coast of the United States, New York and New Jersey, carry a third part of all the traffic of the North Atlantic.




10. There are approximately 1.5 million sailors, the vast majority of whom come from the Philippine Islands.

Importance of underwater ship repairs and maintenance

Standard support and fixes to your boat is a fundamental piece of being a vessel proprietor; it assists with guaranteeing wellbeing and security, keeps your boat in top condition and can set aside you time and cash over the long haul

 

Every so often, a submerged fix is the lone possible alternatives, especially in occurrences of body, propeller and plating upkeep.


Submerged boat fixes can:

 

·       Signify your necessities

 

·        Set aside cash over the long haul

 

·        Lessen time spent in dry dock

 

·        Further develop transport proficiency

 

 Here’s why certain underwater repairs and maintenance are so important:

 

Hull Cleaning

 Maybe the main sort of submerged boat fix, body cleaning ought to be finished consistently.

 By keeping your boats structure spotless and kept up with, you can stay away from terrible shocks like barnacles, marine scavangers that whenever left untreated can connect themselves permanently to the underside of your boat.

 

Propeller Polishing

Regular propeller polishing can assist with diminishing the surface's harshness and thusly, can save huge costs eventually. Smooth propeller surfaces become ungracious to marine living beings, which means the underside of your boat will not turn into a homing ground for marine life that could cause harm.

 

Hull Plate Repairs

 Damaged hull plating can be the result of many factors; natural corrosion, stress from long voyages or unavoidable wear and tear after years of use. Allowing defective hull plates to go unnoticed can cost you, both financially and in time, so immediate repair and maintenance once a fault has been identified is important. Repair methods are varied; from a hydraulic ram to specialist tempering.

 

Underwater Ship Painting 

There will without a doubt be a period where submerged composition or cement work to the lower part of your boat is required, especially if any defensive covering starts to break down and erode. Customary upkeep on your boat's paintwork can assist with hindering such erosion as well as putting aside your money; if rust or oxidization is left for a really long time, it turns into a significantly more costly issue to have.
