Problems solved by technology

The advantage of the jack-up platform is that it requires less steel, low cost, and can perform drilling operations smoothly under various sea conditions; the disadvantage is that the length of the pile legs is limited, which limits its working water depth. The maximum working water depth is about About 120m
If the water depth exceeds this level, the weight of the legs will increase rapidly, and the legs will rise very high during towing, which will be detrimental to the stability of the platform and the strength of the legs
[0005] The jack-up platform uses spud legs to go up and down, and the spud legs need to use the spud shoes at the bottom of the spud legs to contact the seabed after they go deep into the seabed. It is inconvenient to produce, and there are problems of short service life and poor reliability in use

Abstract

The invention relates to the field of ocean engineering equipment, in particular to a high-precision assembling method for a pile shoe of an offshore platform. A main body comprises an octagonal pile shoe assembly and an octagonal pile leg assembly protruding out from the pile shoe assembly. The assembling method comprises the following steps: A, producing the assemblies and manufacturing parts of the pile shoe assembly and the pile leg assembly, wherein the pile shoe assembly comprises a shell, a bottom plate and middle components, and the pile leg assembly comprises a guide plate, a surrounding plate and inclined partition plate components; B, arranging a reference assembly, manufacturing a concave-shaped moulding bed, and restraining the bottom plate on the moulding bed; C, arranging a main body framework, and fixing a main body, composed of the guide plate and the surrounding plate, of the pile leg assembly to the bottom plate; D, installing a reinforcing structure, and arranging the inclined partition plate components on the periphery of the main body of the pile leg assembly in a cross-shaped array mode by taking the main body of the pile leg assembly as the center along the diagonal line of the bottom plate, carrying out welding, and installing the middle components in the intervals of the inclined partition plate components; and E, installing a shell structure, and welding the top and the side surface of the pile shoe assembly to the bottom plate to form a box shape.

Description

technical field [0001] The invention relates to the field of ocean engineering equipment, in particular to a high-precision assembling method for spud shoes of an offshore platform. Background technique [0002] The offshore platform is a structure that provides production and living facilities for activities such as drilling, oil production, transportation, observation, navigation, and construction at sea. [0003] According to its structural characteristics and working status, it can be divided into two types: fixed type and movable type. The lower part of the fixed platform is directly supported by piles, expanded footings or other structures and is fixed to the seabed. According to the support situation, it is divided into two types: pile foundation type and gravity type. The movable platform is floating in the water or supported on the seabed, and can be displaced from one well to another. The supporting conditions can be divided into bottom type and floating type. In...
