Inspection Requirement If washed seat/module is a problem: Confirm minimum of 75% valve seat contact area. On initial installation of seat in module, measure clearance between bottom of seat and module shoulder, minimumby= testing, 0.090”. relief valves are set as near as Confirm possible to liner rating to avoid undue stress on modules due to valves popping off frequently. (Note: Some contractors will not want to set valves higher than about 3000 psi. That is their choice, record liner size, pressure rating and relief valve setting in daily report and trip report.) Record size of DC motor blowers, DC motor power is directly related to motor’s ability to stay cool. HT operations may require 15 HP blower motors. Record last NDE of rod ends, clamps, valve covers and threaded areas on modules. Record date and results of last lube oil analysis. Inspect fluid end internally. Check wear plate seal area prior to installation of new liners. Record pre-charge of discharge dampeners. It is normally 1/3 WP to 750 PSI max unless special bladders are used. Record pre-charge of suction dampeners. Inspect screen in mud pump discharge. Determine that mud pump lubrication system is adequate for long term slow pump rates. National manual page 11. Are auxiliary electric motors and pumps in good condition? Check operation and record pressure of charging pumps; note impeller size. Perform amperage test. Are charging pump motors in good condition? Pressure test HP valves and piping to MWP. Operate each mud pump under a load individually and together for one hour at a pressure equal to 80% of liner rating MWP. Normally choke manifold is required. Plan ahead on a jack-up since rig package normally needs to be cantilevered out to a drilling position. Engine performance will be reviewed at same time. Operation could take longer than one hour if problems are encountered, or extra time is required to evaluate equipment.

Check that both mud pump motors are pulling equivalent amperage. Review pump maintenance records on fluid and power 3.1.18 end to help identify any problems pump may have. 3.1.17

Inspection Requirement

Findings Riser Tensioners, General

Is a program in place to have the system relief valves bench tested and certified on an annual basis. (USCG requires an annual bench test of all relief valves) Record date of last inspection on APVs and relief valves. What did the inspection consist of? Inspect wire rope for signs of broken strands. Is a cut and slip program in place which determines frequency from ton-cycle exposure. Review the cumulative current ton-cycle values for compliance to the program. Note condition and length of spare tensioner wire stored on drums. Visually inspect sheaves for cracks, wear and alignment. Check tensioner and idler sheaves for wear with a sheave groove gauge. Are sheaves free and do they swivel properly? Perform a system pressure test of the tensioners to maximum anticipated system pressure + 20% or to system maximum rated working pressure with the tensioner cylinders fully stroked out. Inspect tensioner rods for signs of damage, peeling chrome, pitting , or indentations. Check oil levels before and after pressure testing. This will check integrity of HP packing.

Hold pressure for 12 hours and record pressure loss, 8.1.11 check for leaks at gland packing area, and note location of any air and oil leaks. 8.1.12 Note type of fluid in tensioners. 8.1.13 Is there indication of oil leakage?

Check fluid level in high pressure accumulator bottles. With bottle bled down and relief valve removed, from 8.2.2 the coupling down to the fluid level should be 35-40 inches. Check the fluid level in the air/oil reservoir with rod retracted into cylinder, oil level should be at lower sight glass. For proper operation of the speed limiting 8.2.3 orifice and rod end hydraulic cushion, proper air/oil fluid levels must be maintained. 8.3

Inspect compensator rods for signs of damage, peeling chrome, pitting , or indentations. Inspect the lock bar to determine if the safety stop will prevent unintentional disengagement. The lock bar lock/unlock position should be remotely indicated on the Driller’s console. Check DSC position indicator for proper operation. Are the compensator hoses properly bundled and protected to prevent snagging on the derrick. Check the guide dolly for loose or missing wheels Check compensator wheel alignment. Activate motion compensator to verify proper operation. Check driller's console for leaks. Perform visual inspection of compensator, control system high pressure air compressors, and relief valves.

Inspection Requirement Relief valves should be set at 2400 psi. MWP is approximately 2260 psi. Ensure all personnel are aware of test and clear of area. Test system and hoses 8.5.1 for 6 hours. Since this test precludes personnel working on rig floor. A minimum of one hour is required if operations will not permit a full test.

Findings

With at least 200 psi extending the cylinders, check each chain for wear and even tension. Document any chain wear damage to the main frame. Review this damage with Shaffer engineering to obtain a disposition for corrective action. No welding should 8.5.3 ever be performed on the main frame or hook frame plates (T-6 material). Only on special situations will Shaffer specify welding on a DSC plate. 8.5.2

Check that excessive chain stretch will not hinder proper operation of the lock bar. Ensure lock bar spring is capable of lifting the lock bar 8.5.5 when load has been lifted from lock bar. Check the fluid level in the air/oil reservoir. For proper operation of the cylinder speed limiting valve and rod 8.5.6 end hydraulic cushion, proper air/oil fluid levels must be maintained. 8.5.7 Are there any indications of improper alignment? 8.6 8.6.1 Compressors 8.6.2 High Pressure APVs 8.5.4

Findings

Inert Gas Fire Fighting Systems Inspect installed inert gas fire fighting systems, i.e., C02, halon. General inspection of entire system to ensure there is nothing to interfere with operation of equipment or access to release controls. Inspect all components of system such as piping, nozzles, valves, sirens, remote pull controls and boxes for visible damage or corrosion. Examine all nozzles and piping for obstructions from paint, oil, grease, dirt or any matter that would interfere with proper operation. Check associated alarms. Record date of last 3rd party inspection. Foam Fire Fighting Systems Date of last foam analysis? Quantity of spare foam on board? Quantity of foam required for system. Type of foam used? (example AFFF 3%) Condition of piping, valves, monitors and check valves? Start foam pump, run for several minutes to check for vibration, overheating or mechanical seal leakage. Check operation from alternative stop/start station. Record date of last major overhaul. Alarms and Detection General alarm. Fire detection alarm. Smoke alarm. Hydrocarbon alarms. Ensure low level alarm initiates at 20%. H2S alarm. Insure low level alarm initiates at 10 PPM, and high level initiates at 20 PPM. Bilge flooding alarms. Machinery space alarms. Can alarms be heard at all points on rig, including inside mud logging unit, wireline work shop and high noise areas? Visible alarm in high noise area? Rig personnel to test one call point, one heat detector, one smoke detector and one flame detector at random from separate zones. Test fault circuits from 2 or 3 zones. Inspect sensors in dirty or recently painted areas for cleanliness and damage. Check control panel and verify all channels are operational on gas detection system. Rig personnel to apply calibration gas and confirm meters display correct percentages of combustible gas as per calibration gas mixtures. Select and test random number of sensors and locations. Plans, Permits and Supervisor's Requirements Check to see if following contingency plans are available on board.
