Description
Technical field
The present invention relates to capstan head, especially one kind outside a kind of FPSO/FSO of marine petroleum development can be used for marine oil and gas
Develop the outer capstan head cantilevered pivoted arm of FPSO/FSO.
Background technique
In marine petroleum development equipment, FPSO/FSO can collect oil storage, emptying (and production) Yu Yiti, economy with it
The advantages such as good, high reliablity, sea area be adaptable, have rapidly developed the mainstream facility as offshore oil and gas production.
Currently, the anchoring system of global major part FPSO/FSO is all made of single point mooring system, wherein outer with pivoted arm
Turret single point anchoring system is easy to operate, highly-safe, and tolerable FPSO/FSO is freely rotated around single-point, and FPSO is made to generate wind direction
Mark effect influences to effectively reduce stormy waves stream active force and then reduce maximum stress, has become in mild sea area operation
The main Mooring Arrangements of FPSO/FSO.
In the single point mooring system of outer capstan head pattern, as the important tie between hull and Single-point system, outside cantilevered
Capstan head pivoted arm bears huge bending and torsion force in operation process, and structure once will make FPSO/FSO by destruction
Stationkeeping ability is lost, the safety of entire FPSO/FSO operation is seriously jeopardized.Meanwhile for FPSO/FSO, anchor chain mooring gear
And the frequency of use such as chain locker are lower, only use under severe sea condition, previous design is all that the covering device is arranged in hull
On main deck, if the covering device can be arranged in pivoted arm, the deck space of FPSO/FSO preciousness can be saved.
How by carrying out reasonable special adjustment arrangement to structure in pivoted arm, so that can both arrange mooring system, from
And achieve the purpose that save deck space, and the structural strength that can guarantee that pivoted arm is had no progeny by between simultaneously just becomes the type pivoted arm
Design difficulty and innovative point.
In conclusion exploitation one type safety, efficiently, practical outer capstan head cantilevered pivoted arm structure are entire systems, single point mooring
Important content in system or even entire marine oil and gas process units exploitation.

Power, the pivoted arm of the present invention positional structure low using first high tail, pivoted arm head end are connected with Single-point system, can guarantee Single-point system
Highly, and then guarantee that Single-point system will not touch water in FPSO/FSO motion process.Three layers of deck and multiple tracks inside pivoted arm
Longitudinal wall, multiple tracks crossing frame form the load-carrying construction of box beam type, and three layers of deck and multiple tracks longitudinal wall, multiple tracks crossing frame form
The box beam type load-carrying construction of upper, middle and lower three, the upper, middle and lower box beam type load-carrying construction can regard three small boxes as
Beam load-carrying construction can also regard the one big box beam load being made of the three small box beam type load-carrying construction in upper, middle and lower as
Structure enhances the intensity of pivoted arm structure using the load-carrying construction of this box beam type, it is ensured that pivoted arm have excellent bending resistance and
Torsional property, and the lower part among the pivoted arm longitudinal wall, with hull junction be equipped with bracket, be effectively guaranteed pivoted arm with
Effective connection of Ship Structure.
This pivoted arm structure that the present invention uses, can enhance the structural strength of pivoted arm, reduce the steel using amount of pivoted arm, mention
High economy can make FPSO/FSO can be applied to the deepwater oil-gas development under mild marine environmental conditions and support.
