Description
Technical field
The utility model is related to a kind of buttress for ship type Floating Production storage handler, more particularly to a kind of ship type floating
Production storage handler large size upper module buttress designing scheme.
Background technology
Floating Production storage handler (FPSO, FLNG etc.) is collection oil/gas production processing, storage and outer defeated, power supply, people
Member the functions such as lives in the comprehensive offshore platform of one, have be applicable in wide depth of water scope, bearing capacity and capacity of anti-storm it is strong,
The features such as maneuverability, has good economic in terms of the far-reaching sea relied in no peripheral facility and marginal field exploitation, is
Main force's equipment of current exploitation of offshore oil and gas.Floating Production storage handler process system is complicated, for ease of arrangement, usually by oil gas
Production processing and related system are divided into difference in functionality module, on main deck.The total weight of upper module is up to up to ten thousand
Ton, different according to function device, the weight of individual module is from tens of tons to upper kiloton etc..In severe marine environmental conditions
Under, the hull of ship type Floating Production storage handler hangs down in being present with, middle doming effect, and module frame may be caused to generate big deformation
Or destroy, equipment or conduit failure are in turn resulted in, is caused the accident.Module stool is the knot of link block frame and main hull
Structure, reliability are related to the normal operation of production and structure safety, are one in Floating Production storage handler structure design
Key technology.
At present, there are mainly three types of forms for the design of offshore floating type production storage handler upper module buttress：Common rigid frame formula, directly
It connects and module frame pillar is welded in module stool, an entirety is formed with main hull structure, between module pillar and buttress
It is slided without opposite；Freely-supported beam type welds part frame pillar and module stool, and part frame pillar connects with module stool slip
It touches, that is, allows have opposite slip between part of module pillar and buttress；Both ends slidingtype, module frame pillar and buttress are all
Sliding contact, without fixed constraint between module pillar and buttress.
Common rigid frame formula module stool design, can not avoid the deformation of hull from influencing module frame, easily be welded in buttress
Position generates fatigue crack, is not suitable for severe sea condition marine site；Freely-supported beam type module stool designs, and can avoid single pillar mould
Block frame single span Direction distortion, but it is not suitable for the heavy die block frame for having multiple rows of pillar；Both ends slidingtype can avoid module frame
Frame deforms, but hull occur larger deep movement when, module pillar easily departs from module stool, be only applicable to sea situation it is good,
The big situation of module weight.
Utility model content
The purpose of this utility model is to store up the large-scale upper module of handler (FPSO, FLNG) for ship type Floating Production,
