Pre-operation Inspection for Offshore Drilling Unit
1 Scope
This Standard specifies the inspection contents, methods and requirements of pre-operation
inspection for offshore drilling and support units.
This Standard is applicable to the pre-operation inspection of offshore mobile drilling units such as
bottom-sitting, self-elevating, semi-submersible drilling platforms, etc. and support units on the
platform. For floating drilling unit, this Standard may be served as a reference standard.
2 Terms and definitions
For the purpose of this Standard, the following terms and definitions shall apply.
2.1
pre-operation
The time from the moment FROM when drilling unit is confirmed to be used in drilling operation
TO the starting time of operation.
2.2
operator
A company which has the right to operate and manages oil and gas mines, or organizes and
operates offshore drilling project.
2.3
drilling contractor
A company which has or uses drilling unit and provides drilling operation services to operator.
3 Pre-operation inspection
3.1 Requirements
Pre-operation inspection shall be organized and carried out by an inspection group. The members
of inspection group shall include the experts in the fields of safety, environmental protection, drilling,
electromechanical industry, and marine affairs, etc. The leader of the inspection group shall be
appointed by the operator.
The inspection group shall make inspection plan and contents based on the characteristics of
operation. The operator shall notify the inspection plan and contents to drilling contractor about
10d in advance.
3.2 Test conditions
In case of one of the following conditions, drilling unit shall be inspected.
— When operator first-time uses the drilling unit;
— When there is significant difference existed in the engineering contents of adjacent operation
contract;
— After the owner of drilling unit is changed;
— After the significant repair or rectification of drilling unit;
— Drilling unit re-operates after having idled for 3 months or more;
— When operator considers that it is necessary.
3.3 Inspection contents and methods
3. 3.1 Certificates and material inspection
Inspect the quality certificates of drilling and support units, qualification of contractor, original
materials and record, management system, operational conditions, etc. The detail contents of
certificates and material inspection are shown in Appendix A.
3.3.2 Inspection of drilling unit and support units
3.3.2.1 Inspection methods
It should adopt intuitive inspection, function test, pressure test, unified operational test,
nondestructive test and disassembly inspection, etc.
3.3.2.2 Intuitive inspection
It should adopt the methods such as eye-inspection, hand-touching and ear-hearing. Intuitive
inspection contents are shown in Appendix B.
3.3.2.3 Function test
Observe the working conditions of all moving parts of control equipment under unladen load or
light load; monitor the range of displayed parameters of each instrument.
It is applicable to underwater & well control system, drilling string compensation system, skidding
system, crown block protector, safety detection and alarm system, power system, emergency
system, rescue system and fire-fighting system.
3.3.2.4 Pressure test
Use test medium to pressurize the system to test its loading and sealing capacities. It is applicable
to underwater & well control system, drilling fluid recycling system, well cementing system, ash
transmission system, and the pipeline and valve of sea water system. The test pressure of low
pressure installations such as sea water and ash transmission systems is the rated working
pressure. If it does not fall within 5min, then it is deemed as qualified. For high pressure installation,
low and high pressure tests shall be conducted separately. The test result of high pressure
equipment shall conform to the design requirements.
3.3.2.5 Unified operational test
Apply load to power, rotating, lifting and recycling systems; then conduct unified operational test.
During the test, the displayed data of relevant instruments such as ampere meter shall be recorded.
The test scheme shall be able to reflect the operational and power matching conditions of single
unit and entire system. The time of load test of drilling fluid recycling system shall not be lower than
6h. The time for the unified trial operation of newly constructed drilling unit shall not be lower than
36h.
3.3.2.6 Nondestructive test
On the condition that the tested object shall not be damaged or destroyed, sound, light, electric or
