3.7 Elevating system 3.7.1 LEG AND RACK

The leg of offshore drillings units is cylinder steel type. There is rack on the bilateral of the leg, and

outside of the leg has guide device.

3.7.2 HOIST AND LOWER UNITS

a) Each hydraulic jacking units includes one hydraulic motor and brake, balancing relief valve, planet

gear speed reducer, hoist and lower gear units.

b) The hydraulic motor is purchased from Parker Co. or equivalent product. After the planet gear speed

reducer, the wheel gear is driven which is joining with the leg gear.

c) The hoist and lower units are installed by bolt on the fixing bracket, at the bottom of which there has

shim block that could compensate the non-uniform on gear caused by abrasion. The position of the

hoist and lower units could be adjusted by wedges which are installed on upside and left side of the

fixing bracket.

d) The planet gear speed reducer has two grades. It’s completely close type, and uses splash system

lubrication. And it has a window for observing the oil level.

e) When the hoist and lower units works, the cracking pressure of the balancing valve is more than the

pressure of relief pressure of brake adding the system backing pressure. It ensures that the brake has

been released before the balancing valve opened, which has avoided the system oil pressure is not

established enough, and the brake has not opened, then the balancing valve opened, so that the

system oil pressure is going to increase, and it will result in equipment damage when the brake opens

suddenly at a high pressure.

f) Because the driving unit always affords the load of the whole offshore drilling units, the circuit of

the hydraulic motor is using reversible balance loop and double safety circuits. The brand of the

balancing valve and relief valve is international well-known brand.

g) Each driving unit is modularized, and when any of which has been destroyed, it could remove from

the bracket and will not influence other units. 3.7.3 FIXING BRACKET

There is one assemblage pry bar on right and left side of each leg, and there should install

seven driving unit on each assemblage pry bar. The assemblage pry bar is welded on the guide

device that surrounds the leg.

3.7.4 HYDRAULIC UNIT

There are four equal pumping stations on the offshore platform, which supply power source for four legs

and brakes of the jacking system separately. The hydraulic units are installed in a symmetric layout. Each
