MAINTENANCE

STRUCTURE AND EQUIPMENT

a. External inspection and routinely checked items.

i. All pins and holes should be checked for wear, elongation and secure fit.

- If hole elongation occurs, it is die to an abnormal load. The origin of the abnormalload must be determined and this operation discontinued. The lug or logs requirerepair/replacement by approved method.

- If wear on pin or hole allows for excess movement then approved repair/replacementis required. Consideration should be given to loading movement and extremity of hazard. Apin to hole difference on 2 dia. and smaller pins is maximum 1/8 on diameter. A pin to holedifference on larder than 2 dia. is maximum 5/32 on diameter.

- If connection is considered unsecure, then approved repair/ replacement is required.- Contact National Oilwell before making any repairs.

ii. Check all pin connections and ensure all pins are held in place by a bolt or safety pin on eachend.

iii. Check all bolts for tightness. Pay particular attention to mast shoes, flanges, clamps, deadlineanchor pigtail, traveling block, crown and other equipment.

iv. Inspect structural components for damage due to handling (load shifts, chain down). Inspect forbent or crimped members. Replace/repair according approved methods.

v. After extreme load cases resulting from operation, check welds. Check for cracks or signs ofdeformity. Repair according to approved methods.

vi. During lubrication intervals check items being lubricated for damage, rubbing, wear and qualityof fit. Replace as required.

Examples:vi-a. Sheaves: Check for wobble, sheave groove bolt tightness, guards in place, wirelines.vi-b. Wireline: Check for line quality, pay close attention to area close to sockets and pins,

sheave guards.vi-c. Rollers/wheels: Check bearings, bushings, rollers/wheels for wear, bearing wear surfaces

for wear, grooving guards as applicable.vi-d. Shafts: Check for wear, eccentricity, end play movement, bearings or bushings.

Just after regular use, check local areas by hand for excess heat. Repair or lubricate asrequired.

vii. During rig up, periodically during operations, and while performing daily operations or specificoperations, check areas for safety. Guards and handrails must be in place and secure. Safetyharnesses must be in place, secure and of suitable quality. Damaged stairs must be repairedimmediately. Hoses, cables, and wirelines must be kept coiled and properly stored when not inuse.

viii. Periodically check for cosmetic damage. Inspect handrails far straightness. Repair as required.ix. Periodically check painting for damage, chipping, peeling and cracking. Note areas with rust or

corrosion and repair immediately. Use approved method of repair. Check for missing ordamaged nameplates, tags, instruction plates or other equipment markings, and replace with


15/515



exact duplicates. Check for proper markings on fluid type in piping. Look for rubbing againstpaint and repair. Review situation to reduce amount of rubbing.

Wireline / Slinglines

a. Check wirelines prior to use when they have been dormant for longer than one month. Inspectwirelines prior to and after extreme loading. For wirelines experiencing heavy usage, it is importantto set up a review and lubrication program that meets the needs of the wireline. When inspectingwirelines, pay particular attention to areas near sockets or around sheaves or yokes. Frequency ofany wireline inspection depends on line application, but should be done a minimum of once amonth.

b. Types of deterioration or damage to inspect for are:i. Corrosion In saline environments, corrosion is a major cause of concern. Every precaution

should be taken to avoid corrosion. Corrosion reduces the metallic areas of a rope, thusweakening it. Also, it mars the surface of the wires by creating stress raisers, which hasten the

development of broken wires. The most dangerous feature of a corroded rope is that it isalmost impossible to ascertain the true condition of the rope. Areas adjacent to endconnections should be examined closely for any evidence of rust. A significant amount ofcorrosion other than minor surface rust, should be cause for replacement. Proper lubrication ofthe wireline will combat corrosion.

ii. Abrasion The ability of wire rope to withstand wear when operating over sheaves, roller, anddrums or when rubbing over stationary objects is the measure of its resistance to abrasion.Larger diameter wires will withstand abrasion to a greater degree than small wires, therefore,the coarsest rope construction such as 6 x 7 will have a higher resistance to abrasive wear thana 6 x 16 classification. A line showing significant reduction in area or broken wires fromabrasion should be replaced.

iii. Elongation When a significant increase in length is evident in any section or rope, it should bereplaced. Elongation is accompanied by a diameter reduction that can be measure with calipersand compared to original measurements taken when the rope was new. Diameter reductions of1/16 or more in 1 1/8 ropes and 3/32 for 1 to 1 ropes are cause for replacement.

iv. Broken Wires A line with any broken wires should be replaced. Breaks often occur in thevalleys of the line and require close inspection to locate.

v. Damage Avoid leaving the line or handling the line where damage such as kinking, crushing,heat damage resulting in distortion of the rope structure could occur. Any such damage shouldbe cause for replacement.

c. For further guidelines on wire ropes see API Recommended Practice on Application, Care andUse of Wire Rope for Oil Field Service, API RP 9B Latest Edition.

GENERAL NOTES

a. Most fixtures and accessories are already assembled to the structure, and all equipment is in placeor accommodated prior to field installation. If, however, anything needs to be added or modified,then recommendations from the manufacturer are required. Do not drill or burn holes or weldunless approved methods are strictly adhered to and there is consultation with National Oilwell.

b. Due to the nature of pin installation, whereby, they are scraped or scratched, there is a possibilityfor corrosion / rusting of the pin or connecting lugs. During pin installation, apply a light oil to thepin. This will maintain a more corrosion free environment and improve pin and connection life.


16/515



c. Disassemble only when and to the extent necessary to repair or replace defective components.This action reduces the possibility of contaminants entering the system. It reduces possibleunnecessary damage to sensitive areas. It reduces possible incorrect re-assembly. This willminimize unnecessary downtime.

Always disassemble by approved format and with proper disassembly methods.d. Replace all oil seals and gaskets when exposed during assembly.

e. Protect uncoated clean parts, if not to be used immediately, with a preservation compound, toprevent rust and deterioration.Protect uncoated exposed areas or surfaces such as threads or machined surfaces to prevent rustor deterioration. When coating operating surfaces, use a coating compatible with the lubricant.

f. Identify pipelines, connectors, and electrical wires as each is removed or disassembled to ensureproper reconnection when assembling.

g. Review specific maintenance manuals for specific equipment.

LUBRICATION AND MAINTENANCE

a) The structure should be operated and maintained as required by API Standards and localregulations. Where the two overlap, the stricter rules should govern.

b) Lubricationi. Sheaves require a #2 lithium base lubricant with extreme pressure resistance qualities atelevated temperatures. Greasing should be done at regular periods, which depend on theconditions.

ii. All wirelines, must be kept coated with a good rope lubricant at all times.c) Operating and Maintenance

i. Careful, periodic checking of the structure will assure safe, dependable and economicalservice of the rig.

ii. Cap plates on all shafts and all wired bolts should be checked regularly to assure that thebolts are tight and the retaining wires in place.

iii. Inspect the wirelines on a regular basis. Pay particular attention to areas near sockets oraround sheaves.

line with any broken wires should be replaced. line with significant net area reduction resulting from wear should be replaced. line with signs of corrosion other than minor surface rust should be replaced. kinking, crushing, or any damage resulting in distortion of the rope structure should

constitute immediate replacement.iv. Any damage or distortion of the structural members should be repaired immediately.

National Oilwell should be contracted prior to any repair, reinforcement, or other modificationto ensure the structural acceptability, proper engineering design, fabrication and installationof the proposed modifications, and to ensure that adequate repair methods and proceduresare followed so that the certification given by National Oilwell is not impaired.

2.1 Operating conditions

The standard HPU is designed for the conditions listed below. If the requirements areoutside of these conditions listed below, contact your National Oilwell representativewith your specific requirements for special design considerations.

Ambient temperature:Location:

2.2 Cooling water

The cooling system is primarily designed to operate with clean water.

When there are particles in the water, larger than 0.02 in. (0.5 mm), a water filter mustbe used.

It is important to:

Maintain the water filter (if any) in a correct way, this is to get the required flow ofwater through the water oil cooler.

Ensure you have the required flow, pressure and temperature of the cooling water(see attached technical documentation).

Check the temperature in the hydraulic system, according to the maintenanceintervals on the chart.

Clean the cooling system if the temperature in the hydraulic system is above thespecified limits.

Clean and empty the cooling system (waterside) before periods of inactivity

(especially if the cooling water is not totally clean).

IF THE COOLING CAPACITY IS TOO LOW, THE SERVICE LIFE OF COMPONENTSIN THE POWER UNIT, AND THE HYDRAULIC FLUID WILL BE REDUCED.
