Description

[0001] The present invention relates to an upper module lift-up restraint unit, an equipment module supporting apparatus including the upper module lift restraint unit, and an FPSO (FPSO)

The present invention relates to an upper module hold-up restraining unit, and a facility module supporting apparatus and FPSO including the same, and more particularly, to an upper module hold-down restraining unit capable of stably supporting plan devices at the upper portion of a floating hull, A facility module supporting device including the same, and an FPSO.

FSPO, a floating composite production system with facilities to produce, store and unload crude oil and natural gas, is equipped with modules for each process. These modules have different roles to perform for each module, and thus have individual characteristics and shapes, and have various weight and reaction values for each module.

Basically, each module is located on the topside of the FPSO. Depending on the capacity and oil site of the FPSO, the characteristics, shape, and process of the module are different, The weight is determined.

For example, the Flare tower, Turret and Pipe rack are fixed to the hull. Even if uplifting occurs, the movement of the FPSO However, the remaining modules are mounted with a special uplift restraint structure that can restrain the uplift when it occurs.

The corresponding module of the FPSO that needs to be placed in this constrained structure has four types of constraints according to the hearing by the module support stool (MSS).

First, in the constraint for the module, the constraint for vertical motion is V, the constraint for pitch motion is P, and the constraint for rolling motion is R.

At each lower corner of the module, an audible restricting unit providing restraint conditions of V, VR, VPR, VP can be arranged in a clockwise direction. In the case of VP and VPR, the pitch motion for the module is constrained. If the restraint of pitch motion is constrained by VR, additional moment and additional force are generated. The same phenomenon occurs in the case of the roll motion.

At this time, there may be a question about whether or not the motion for the lifting of each corner can be constricted, which can be explained by focusing on the efficiency of the design.

That is, it is not necessary to dispose the lifting and restraining unit having all the constraints on the edge of the module, and all the structural conditions and the weight are taken into consideration, and advantageous constraints can be placed so as to achieve the maximum effect with minimum cost. Accordingly, there may be a module support stool (MSS) that restricts only the vertical (+ Z) direction, i.e., provides only the V constraint.

As described above, the weight of each module is determined by the function and shape of the module, and the module support stool (MSS) is determined according to the weight, function, and shape.

In order to maintain the position of each module in the + Z direction, a yoke beam (Elastomeric bearing) and a Y-beam (Y-beam) ) Were installed.

The module support stool (MSS), which includes the Yorke beam and the elastomeric bearing to provide such conventional V constraints, can be used for uplift brackets Uplift Bracket) was removed and the bearing had to be replaced. After that, we installed the uplifting bracket again in the same way.

As described above, a module support stool (MSS) including a yoke beam and an elastomeric bearing, which provide a conventional v-constraint, is installed most in each module requiring an aperture constraint.

However, such a module support stool (MSS) requires maintenance periodically because of the service life of the elastomeric bearing. During these maintenance, expensive elastomer bearings must be replaced.

As described above, the above-mentioned lifting and restricting unit, which provides the existing V-constraint, has a problem in that expensive elastomeric bearings must be replaced and replacement work for the elastomeric bearings is complicated, thereby increasing the overall maintenance cost.
