AS LAID SURVEY REPORT
POST TRENCHING OF 24” PIPELINE IDENTIFICATION
The subbottom profiling survey to determine the burial depth of 24” submarine pipeline between KP 0.740 and KP 4,Labuhan Maringgai, Java Sea, have been performed between the date of 6 May 2014 and 8 May 2013 by using a survey boat of Mv. Juliyana Jaya.
The subbottom profiling survey system used during the survey performed was Innomar SES 2000 while the positioning system used was Seastar HP 8200 DGPS with Hypack 2014 navigation software.
Between the date of 6 May 2014 and 8 May 2014, weather condition was relatively good.
Based on preliminary evaluation of acquired data, it can be concluded that:
Maximum and minimum depth (natural seabed) found across the survey area is 3.5 m and 4.5 m
Minimum and maximum top pipe depth of 26” pipeline is 2.5m at KP-0.74 and 6.67 m at KP-1.
Tabulation and capture of data samples are enclosed at the end of this preliminary report.
