Semi-submersible ships capable of being combined and combined type semi-submersible ship

Abstract

The invention discloses semi-submersible ships capable of being combined. Each semi-submersible ship capable of being combined comprises a ship body deck and a forecastle arranged on the ship body deck, wherein the forecastle on one side of the main center line of the ship body deck is a movable forecastle capable of being detached and moving, and the movable forecastle can move to any position of the spacious deck. The invention further discloses a combined type semi-submersible ship which is formed by integrally connecting one side of the ship body deck of one semi-submersible ship capable of being combined and one side of the ship body deck of the other semi-submersible ship capable of being combined. The movable forecastles are moved to one sides of the ship body decks respectively to be close to corresponding fixed forecastles, so that the deck formed by the two semi-submersible ships capable of being combined passes through the front portion and the back portion of a stern. The combined type semi-submersible ship has the advantages that the requirement for conveying larger unconventional heavy pieces can be met, and meanwhile economic cost can be taken into consideration; the combined type semi-submersible ship can be divided into the two conventional type semi-submersible ships in the operating period when the unconventional conveying is not needed; accordingly, operating cost is reduced.

Description

【Technical field】 [0001] The invention relates to a semi-submersible ship, in particular to a combinable semi-submersible ship and a combined semi-submersible ship. 【Background technique】 [0002] Semi-submersible ships (Semi-submersible ships), also known as semi-submersible mother ships, are ultra-long and overweight ships that are specialized in transporting large offshore oil drilling platforms, large ships, submarines, gantry cranes, and prefabricated bridge components, but cannot be separated for lifting. Special marine vessel for large equipment. When the semi-submersible ship is working, it will be like a submarine. By adjusting the ballast water volume of the hull, it can smoothly submerge a hull deck the size of a football field into the water at a depth of 10-30 meters, and only the ship building is exposed. Then, when the goods to be shipped (such as yachts, submarines, barges, drilling platforms, etc.) are towed above the submerged loading deck, start a large a...

AI Technical Summary

Problems solved by technology

However, the disadvantage of this arrangement is that the length of the cargo carried is greatly limited

Existing semi-submersible vessel technology cannot load ultra-wide offshore platforms due to the limitation of vessel width, such as semi-submersible offshore platforms, which cannot be properly loaded on existing semi-submersible vessels due to their wide bottom structure

Therefore, the shortcoming of the existing semi-submersible ship is that the width of the cargo carried by it is limited

If it is necessary to build a semi-submersible vessel with a larger tonnage to meet the transportation requirements of longer and larger cargo, more funds need to be invested, and extremely high operating costs will be generated after it is put into use, which is economically unbearable for the charterer

Therefore, the existing semi-submersible ship cannot flexibly meet the needs of the existing shipping market due to its insufficient loading structure
