Once the shipping beam has been removed, and the four (4) support legs and braces of modular air cooler have been installed, lifting and erection of the modu modula larr air air coo coolers lers shal shalll com commenc mence. e. SATE SATEC C Heav Heavy y Lift ift Subc Subco ontra ntract ctor or (MAMMOET) will do the lifting and rigging works of the modular air cooler. •
As soon as the modular air cooler has been lifted / placed on its final position, proper alignment, alignment, plumbness plumbness and bolt tightening shall be carried out in accordance accordance with SATEC/UNITED Job Specification and MS-M-031 Rev.0, Method Statement for Equip Equipme ment nt Insta Installa llatio tion n respe respecti ctive vely. ly. Upon Upon comple completio tion n of align alignme ment nt and bolt bolt tightening, the column base plate and setting plate shall be seal welded. •
While preparing the modular air cooler for erection , assembly and erection of pre-fabricated structural support shall be carried out in accordance with good working practice & SATEC/UNITED Specifications as well as an Approved Safety Action Plan. •
-
DoubleDouble-che check ck the pre-fab pre-fabric ricated ated structu structural ral support support material materials s lists lists as per IFC Erection Drawings & Member Piece Mark Numbers of E-2311 A-J as provided by SATEC/UNITED. Any deviation against the issued drawings or defects on the members encountered during the sorting/checking shall be immediately reported to SATEC/UNITED for their information and appropriate action.
-
Use a 20-50 ton crane for loading and unloading of pre-fabricated structural support to a 40-ton trailer, which shall transport the frames from temporary yard within the site or from materials lay-down area to the erection site.
-
Ensure that all lifting and rigging works are executed in accordance with MMG Stand Standar ard d Oper Operat ating ing Instr Instruct uction ion No. PRJPRJ-4-0 4-027 27 and and SATE SATEC/U C/UNI NITE TED D Job Job Specification respectively.

4.0 ton (see attached drawing JUEG-MMG-LP-17 Rev.0). The assembly shall include the preliminary tightening of bolts. Once Once the structur structural al support support is assemb assembled, led, erection erection sequenc sequence e will start from Northerly most framing column line 117, Section A and move towards South going to Section C. See attached drawing JUEG-MMG-LP-17 Rev.0. Then, install the connecting beams, girder and braces between Section A , B and C.
•
Prior to adjustment, alignment, plumbness and bolt tightening activities, ensure that the assembled structure is fully supported by guy wires connected to a chain block, which is attached to column foundation.
•
Alignment, adjustment, plumbness and bolt tightening shall be carried out in accord accordanc ance e with with SATE SATEC/ C/UNI UNITE TED D Job Job Spec Specifi ificat cation ions s and and MS-C-0 MS-C-032 32 Rev. Rev. 02, 02, Method Statement for Erection of Structural Steel for Piperack 81 respectively. •
The same methodology shall be applied for the erection of all of the Air Fin Coolers, E-2311 A-J / E-2221 A-D (see JUEG-MMG-LPA-17 Rev.0) until the last equipment is completely installed to complete the system. •
