Description

4ê$ Nå skall utföras, . fig. 2a, b visar baljan vattenfylld, dvs. i nedsänkt till- stånd, fig. 3a, b visar baljan influten under skrovet, fig. 4a, b visar den länspumpade baljan varvid skrovet lyfts upp några centimeter och det är möjligt att gå på baljan, fig. Sa-c visar konstruktionen av baljan i längdsektion,_vy ovanifrån resp. i perspektivvy och fig. 6s-h visar dockning av en jack-upp-rigg. 4ê $ Well to be done,. Fig. 2a, b shows the tub filled with water, i.e. in submerged condition, Fig. 3a, b shows the tub inlet under the hull, Fig. 4a, b shows the bilge-pumped tub whereby the hull is lifted up a few centimeters and it is possible to walk on the tub, Figs. Sa-c shows the construction of the tub in longitudinal section, _view from above resp. in perspective view and Figs. 6s-h show docking of a jack-up rig.

I fig. l har en balja 5 förts längsides med ett skrov 2, som över stabiliseringspelare 3 är förbundet med en plattform 1.In Fig. 1, a tub 5 has been moved longitudinally with a hull 2, which is connected to a platform 1 via stabilization pillars 3.

Baljan 5 hålls i detta läge med hjälp av ej visade bogserbåtar. Alla tankar är tömda och så är även baljan.The tub 5 is held in this position by means of tugs not shown. All tanks are emptied and so is the tub.

Baljan har ett bottengaller 12 som har pallningsvirke på olika ställen. I fig. 2 visas baljan 5 vara vattenfylld och med hjälp av en stabiliseringstank 9 kontrolleras baljans läge och djupgång. Mooring-linor läggs ut till skrovet 2 och bogser- båtarna assisterar vid inflytningsmanövern (vilken inte visas i detalj). Baljan Sïkan även inifrån skjutas under skrovet 2, i synnerhet om utläggning sker av utåtvända förankringslinor.The tub has a bottom grid 12 that has pallet wood in different places. In Fig. 2, the tub 5 is shown to be filled with water and by means of a stabilization tank 9 the position and draft of the tub are checked. Mooring ropes are laid to the hull 2 and the tugs assist in the moving-in maneuver (which is not shown in detail). The Sïkan trough is also slid under the hull 2 from the inside, especially if outward-facing anchor lines are laid.

Fig. 3 visar att baljan 5 medelst linor och bogserbåtar förts- till sitt riktiga läge relativt skrovet 2. Stabiliseringstank-_. arna 9 och balanseringstankarna 8 töms. Inom kort dyker baljans kantpartier 7 upp ur_ vattnet. Baljan 5 länspumpas tills skrovet 2 lyfts upp några centimeter. Ur fig. 4 framgår att skrovet 2 lyfts uppåt några centimeter. Återstoden av vattnet i baljan 5 pumpas in i balanseringstankarna 8 och i stabiliseringstankarna 9. Baljan 5 torrläggs således men halvdykkroppens flytläge ändrar sig inte. i i F 4 21: Konstruktionen av baljan 5 framgår ur fig. Sa-c. Offshore- plattformarna kan vara utförda såväl som ha1vdykÉroppar_som Jack-upp-riggar 14 (fig. 6); _ ßflw-qfw- -w-w _.. __ A. ii 4 aflwsfiw k; i i F :wpnnmr-fl :w-ø-www-flv* -H,_Fig. 3 shows that the tub 5 by means of ropes and tugs is moved to its correct position relative to the hull 2. Stabilization tank-_. the tanks 9 and the balancing tanks 8 are emptied. Soon the edge portions 7 of the tub appear out of the water. The tub 5 is bilge pumped until the hull 2 is lifted up a few centimeters. Fig. 4 shows that the hull 2 is lifted upwards a few centimeters. The remainder of the water in the tub 5 is pumped into the balancing tanks 8 and into the stabilization tanks 9. The tub 5 is thus dried but the floating position of the half-dive body does not change. i i F 4 21: The construction of the tub 5 is shown in Figs. Sa-c. The offshore platforms can be designed as well as surface dives like jack-up rigs 14 (Fig. 6); _ ß fl w-qfw- -w-w _ .. __ A. ii 4 a fl ws fi w k; i i F: wpnnmr- fl: w-ø-www- fl v * -H, _
