TYHI has the ability to design and manufacture jack-up drilling
platform. It is a non-self-propelled,self-elevating drilling
platform used for offshore oil and natural gas exploitation and
development operation. TZ400 Jack-up Drilling Platform is intended
for operating in water depth up to 122m (400ft), provided with such
functions as drilling of deep well, cluster well, horizontal well,
cementation and auxiliary oil test.
TZ400 Jack-up Drilling Platform is suitable for operation in sandy
or silty seabed, with the functions of drilling of deep well,
cluster well, horizontal well, cementation and auxiliary oil test.
It is intended for operating in water depth up to 122m (400ft) with
a drilling capacity of 9000m (30000ft). The main performance is as
follows: the accommodation reaches 150 persons, the max variable
load is 3900t; the max hook load is 675t and the rated draw work
power is 2880kw. Furthermore, multiple key equipments are imported
from abroad, such as BOP from Cameron, top drive and high pressure
valve set from NOV, main generator from CAT, mud solid control
system from Derrick, well meeting the performance requirements of
TZ400.
