Abstract

Abstract. Heavy lifting on an E-House Module 245 T is using Crawler Crane 1250 T with single lifting while moving on the soft soil ground is most riski and prone to the setllement. The heavy module that are lifted in unstable ground bearing areas will move due to the settlement from soil which can cause damage to module. A site activity of the lifting plan of the module used Crawler Crane 1250 T was conducted to investigate the effect of radius operation and COG Centre of Gravity to be considered for the lifting plan. In this result the rigging sling get safety factor as the lowest it is 1.06, the crawler crane get safety factor is 1.22 and the ground bearing safety factor is 1.53. The load from E-House Module get from the weigingb report is 245 T with the COG XCG 7860 mm , YCG 437 mm and ZCG 5840mm, the module dimension is 18200 mm x and 9000 mm y and 16400 mm z.

Abstract

Abstract. Mooring Line Pre -Lay and Installation Procedure is using AHTS with the power engine 30.000 BHP and has capacity of bollard pull 300 ton is used for mooring line installation for FPSO Marlin Natuna. The Mooring Installation often fail due to the anchor drag during testing. In this site activity the anchor drag is used. The type of anchor drage is strevpris MK6 with the weight 15 ton and after installation it should be test loaded 243 ton, it is 80% from his capacity 304 ton. The Acceptance criteria for the mooring installation is the anchor can not allow drage out of the target box, with allowable drage 13-16 m, during tension test with 30 minute the holding time. The result from the site activity of the mooring line installation as follow ; the tension mooring line number 1,2,3,4,5,6,7,8 are pass with the tension test 250 ton, and the final position of all anchor within in the target box eith the maximum drag 2m.
