Abstract
Ovaj rad se sastoji iz dva dijela. U prvom dijelu su opisane sve faze koje prolazi postolje fiksne platforme od samog projektiranja i izrade na kopnu, do njegove instalacije na odobalnoj lokaciji i skidanja uzgonskih tankova. Poseban naglasak je stavljen na završnu fazu, tj. na skidanje uzgonskog tanka. Konstrukcija koja se spominje u ovom radu koristi se prilikom instalacije fiksnih platformi na dubinama do 400 metara. U okviru drugog dijela provedena je dinamička analiza u... More vremenskoj domeni, za odobalnu operaciju podizanja uzgonskog tanka iz vode. Na osnovu rezultata dinamičke analize izabrani su granični vremenski uvjeti pri kojemu se operacija smije izvršiti. Dinamička analiza je provedena pomoću računalnog programa MOSES. Sam diplomski rad izrađen je u suradnji s odjelom NAVAS, tvrtke SAIPEM S.p.A. Rijeka. Na osnovu provedenih rezultata dinamičke analize može se zaključiti da su, prilikom podizanja uzgonskog tanka, dominantna opterećenja koja se javljaju uslijed interakcije konstrukcije i valova. Gibanje DB-a je imalo manji utjecaj na sile koje se javljaju u opremi za podizanje tereta. Uz pretpostavku da sustav za sidrenje DB-a, kompenzira gibanja drugog reda. Less
Abstract (english)
This paper consists of two parts. The first part describes all the phases that the fixed platform pedestal goes through, from the design and construction on land, to its installation on the offshore site and the removal of buoyancy tanks. Special emphasis was placed on the final phase, i.e. the removal of the buoyancy tank. The structure mentioned in this paper is used when installing fixed platforms at depths up to 400 meters. In the second part, a dynamic analysis in the... More time domain for the offshore operation of lifting the buoyancy tank from the water was performed. Based on the results of the dynamic analysis, the boundary weather conditions under which the operation may be performed were selected. The dynamic analysis was performed using the computer program MOSES. The thesis itself was prepared in collaboration with the NAVAS department, SAIPEM S.p.A. River. Based on the results of the dynamic analysis, it can be concluded that, when lifting the buoyancy tank, the dominant loads that occur are ones due to the interaction of structure and waves. The movement of the DB had less of an impact on the forces occurring in the lifting equipment. With the assumption that the DB anchoring system compensates for second-order movements. Less
