Process for keeping ocean structure in upright or inclined state

The invention discloses a process for keeping an ocean structure in an upright or inclined state. The process comprises the following steps that 1, hook heads of two cranes are used for tensioning a vertical piece structure and lifting the vertical piece structure to sliding shoes; 2, the vertical piece structure is evaluated; 3, the stress values of cable ropes are computed; 4, according to the determined extreme condition, the fixing modes of cable ropes at the structure end are determined; 5, the angles between the cable rope structures and the structure are adjusted to the set angles; 6, the inclination angle of the vertical piece structure is adjusted and measured through the cranes; 7, one cable rope structure is tensioned, and the inclination angle is measured; 8, the cranes are slowly released until the hook head on one side is taken off; 9, the steps 7-8 are carried out repeatedly until the hook head on the other side is taken off; 10, the vertical piece structure is completely tensioned and fixed by the cable rope structures and keeps in the upright or inclined state. The process not only can fix the ocean structure to the appointed position and keep the ocean structure in the upright or inclined state to meet the operation requirements, but also can greatly reduce the construction cost of the ocean structure.
