Method used for carrying and launching drilling platform in ocean engineering

Abstract

The invention discloses a method used for carrying and launching a drilling platform in ocean engineering, and relates to the technical field of ocean engineering equipment and large ship construction. The method can be used for carrying and launching operations of various ocean drilling platforms and large ships, and comprises the following steps of: after the drilling platform finishes folding on a dock, designing a sideway, arranging a slide plate and remolding a semi-submerged barge so as to carry, load and fix the semi-submerged barge on water and launch the drilling platform. The method has a great influence on safe completion and delivery of maritime products in a maritime product manufacturing process. The carrying and launching process method has the characteristics of safe and reliable operation, high constructability, high universality, less construction volume, short construction time, less investment, and remarkable economic benefit.

Description

Technical field: [0001] The invention relates to the field of marine engineering and ship product construction, in particular to a method for loading and launching an ocean engineering drilling platform. Background technique: [0002] Ship launching is the process of moving the ship from the construction area to the water after the construction of the berth is basically completed. It is an important link in the ship building process, and it is also a relatively complicated process. There are many factors that affect the safety of launching a ship. If the analysis of various factors is not done before the launching of the ship, unexpected events may occur due to poor consideration in advance, resulting in immeasurable losses. Therefore, the ship launching process needs to be scientifically designed and manufactured, and the entire launching process needs to be related to detailed calculation and process design. Therefore, it is a long-term research and discussion topic to se...

Problems solved by technology

High investment, long construction period, and underwater slides cannot be recycled

2) Airbag launch: use high-pressure inflated rubber airbags to bear the weight of the ship. The rolling deformation of the airbag and the weight of the ship combined with the slope of the land make the new ship launch smoothly. However, the airbag is prone to uneven internal pressure of the bag wall, and it is easy to cause delamination and blistering Phenomenon, even the danger of sudden burst

Although the floating dock launching facilities have the ability to dock with multi-position horizontal berths, the operation is complicated, and most of the time it needs to be equipped with deep water sinking pits

In a word, none of the above methods can form the equipment and process for launching large ships in a short time and at a low cost.
