TITLE ROTATIC EQUIPMENT WORK PROCEDURE

2.

PURPOSE AND SCOPE 2.1

The purpose of this procedure is to describe and define the methods applied in rotated Equipment Work Procedure in Pulau Sambu Tank Refurbishment Project.

2.2

This procedure is also general guidance for preparing the standard operation procedure (SOP) for practical detail instruction on rotating equipment installation at site. The specified Standard Operation Procedure (SOP) shall be prepared by Superintendent as per type scope of work. This SWP shall be prepared before starting the work and approved by Client / Owner as required.

2.3

This procedure covers for the following:  

3.

4.

5.

The method of cleaning, field preparation, and acceptance criteria for the result. Where an ambiguity is detected between client specification and this working procedure, the requirement in the specification shall take precedence.

Owner Procedure

RESPONSIBILITIES 4.1

The Construction Manager is responsible to implementing the provisions of this procedure. He shall ensure that the Quality Control Engineer and the Client or Vendor Technical Service witness and approved the alignment check of the inspection required by this procedure and Project Quality Plan.

4.2

The Quality Engineer is responsible for witnessing the inspection required by this procedure and assuring that the established requirements are met.

APPLICATION OF PROCEDURE 5.1

Positioning Equipment a. Anchor Bolts in foundation shall be inspected prior placement of sole plate or equipment on the foundation. b. Anchor Bolt location and corresponding holes in sole plates and equipment shall be checked to insure that all components are matched.

c. Anchor Bolt shall be checked for elevation and position using and established bench mark. d. Anchor Bolt shall be straight and plumb, it is also inspected for damaged threads, dies may be run over anchor bolt to clean up thread, which are dirty. e. Anchor Bolts shall be clean. All loose concrete, water or other debris shall be removed. f.

Anchor Bolt that are damaged or improperly located shall be repaired or replace as per Client representative approval.

g. Anchor Bolt shall be torque as per vendor requirement. h. Foundation shall be inspected for soundness, roughness and cleanliness prior to grouting.

5.2

i.

Shipping instruction, manufacturer drawings and specifications of equipment or motor shall be checked for lifting, moving and protection procedures.

j.

Equipment shall be clean up of all sand, and other foreign materials immediately after removal from storage and before the equipment is brought in installation sites. Steel shim shall be used under all equipment and motor. Contract drawings or specification shall be checked for shim requirements. Clearance between anchor bolts and bolts hole shall be checked after placement of the equipment to be sure there is not binding or distortion.

Shimming a. Shim for final alignment and for placement or repair of motors and equipment, minimum thickness of this shim shall be 1/8 inch. b. Shim for elevating, leveling and support of motors and equipment. Steel shim shall be placed on each side of anchor bolt to properly support the equipment from the foundation. Steel shim shall also be used where required to prevent distortion, binding breaking, leveling of equipment soleplates and supports. Steel shim shall be located to A minimum distance of 1/4 inch from the anchor sleeve and 1/4 inch form the anchor without sleeves. Minimum width for these shim shall be 1 inch. Steel shim does not need to be removed for grouting unless other specified.

5.3

Alignment a. Equipment and motor that have been placed shall be leveled to the elevation and positioned. Specific clearances indicated on manufacturers drawing or in instruction manual such as rotor clearance to housing on fans, thrust bearing clearances or setting, shaft deflection, heat differential rise between equipment shall be checked before final alignment between each item of equipment. b. When one or more items of equipment or motors are to be connected by coupling or other means, level the position the items first. c. Shaft alignment and tolerances. The alignment of rotating machinery shaft shall be as close to perfect as practicable. The tolerances for coupling and shaft alignment shall be no greater than those indicated in the installation

instruction or as follows, whichever is more stringent. After due allowance for differential thermal expansion of components and for shaft sag, the face to face distance between disconnected coupling halves at the diametrically opposite points on their outer edges shall not differ by more than 0.05 mm (parallel offset) or the manufacturer tolerance, whichever is less. The horizontal and vertical eccentricity of one half of the coupling relative to the other shall not exceed 0.05 mm (Angular offset). The actual reading shall be recorded. d. Dial indicator used for coupling and shaft alignment shall be calibrated and controlled prior the alignment started. Feeler gauges shall be used to measure angular offset when the coupling is on a motor having sleeve bearing, and when space limitation prevent the use of a dial indicator. Gap tolerance or hub space preparation shall be as per drawing requirements or Client specification. Gap tolerances don’t apply for limited end float and slide coupling application. 5.4

Inspection a. When equipment and motor have been aligned and are ready for inspection, the QC Engineer shall arrange and to invite the Client representative to witness and approve the alignment check. The alignment records or required by Client, shall be filled in and signed at this time. b. Copies of the alignment record shall be given to the Client or his authorized representative. c. Any request by Client at this time to delay grouting or doweling shall be written. The Client shall be informed in writing that any re-alignment required as a result of this delay that has impact to the schedule shall be his expense.

5.5

Grouting and Doweling a. Grouting and doweling of the equipment and motors shall be done following acceptance from signing of inspection record of alignment check. b. Equipment and motor shall be grouted as per requirement of manufacturers installation manual. Tapered, removable dowels shall be used unless otherwise specified. c. Dowels size shall be per manufacturer’s specification.
