capstan winch

25a, 25b can give rise to the top 43 of base 40 position of Fig. 5 E) of A glyph framework.The bottom of lifting equipment is connected in the top 43 of base 40 pivotly.And

capstan winch

25a, 25b are seated in the place far away apart from pillar 11, and away from the operation relevant with rig.

Capstan

winch

25a, 25b then pack up cable 29, with the top 43 of lifting base 40, shown in Fig. 5 E.In this position, cable 29 is located shown in Fig. 5 E with respect to the part on the top 43, namely avoids the various parts on the top 43, and cable 29 can not hinder movement and the operation on the top 43 like this, also can not hinder the operation on every side of rig, especially pillar.

Shown in Fig. 5 E, for make mobile effectively and lifting force effective, when

movable sheave

16a, 16b move down at pillar, when being connected to the top 43 of base 40 then,

movable sheave

16a, 16b are connected on the position at top 43 of base 40, compare the center at more close top 43, this position (center shown in Fig. 5 E) with the distance between the end (left end shown in Fig. 5 E) at this position and top 43.Still shown in Fig. 5 E, the A glyph framework remains on the appropriate location between the rig operational period, those cables are attached to and extend between

pulley

26a, 26b, 27a, 27b and

capstan winch

25a, 25b, and the system that makes is positioned at the appropriate location, with described top 43 and the pillar 11 of descending when needed.The movable sheave assembly moves down in orbit, and the corresponding eyelet on the eyelet on the movable sheave assembly and pillar (wherein removably being inserted with pin) is to it, and wheel keeps being connected with the movable sheave assembly simultaneously.

Inland rig can be dismantled by the step of enumerating above putting upside down.

Shown in each figure,

capstan winch

25a, 25b are seated in the place (for example Fig. 1,3) of the drilling well end (platform and pillar) away from rig, like this, compare with the position near the drilling well end of rig, capstan winch, cable and relevant device thereof and parts meet with less corrosion and pollution.
