Prosedur
Standard Operating Procedures
Keterangan
Spesifikasi Survei dan Monitoring Pre-lay Survey harus dilaksanakan tidak Pre-lay Survey lebih dari 30 hari dari batas kegiatan aktivitas peletakan pipa. Survei hidrografi dan profiling harus dilaksanakan untuk memeriksa kelayakan Pipelay Support konstruksi pipa di dasar laut, identifikasi span. Monitoring koordinat pipa (x,y,z), kemungkinan free span yang terjadi, dan inspeksi kegiatan welding dan coating di As-laid Survey setiap station, perekaman data hidrografi dalam setiap pergerakan pipa. Pre-lay trenching control untuk analisis bottom roughness. Post-lay trenching, meliputi TOP survey,DOB, dan penentuan OOS. Survey for buried pipe sections
As-laid survey meliputi profiling survey, inspeksi ROV untuk pipeline status dan free span assessment. Survey for unburied pipe sections Span correction support meliputi penentuan lokasi dan dimensi span. Post rectification/Final Survey Spesifikasi Operasionalisasi Peralatan Survei dan Navigasi Persiapan Sistem untuk RTK dan DGPS GPS receiver Trimble 4000Ssi (or equivalent) RTK out-off Pacific Crest PDL UHF radio modemtranceiver (or equivalent). Antenna radio Sufficient batteries Base station Reference Sistem untuk DGPS di MCOT station GPS receiver AgGPS 132 beacon out-off (or equivalent) Pacific Crest PDL UHF radio modemtranceiver (or equivalent).

GPS/RTK system calibration 1 unit receiver GPS akan diinstal di onshore benchmark (base station) pada titik yang telah ditentukan di MCOT . Posisi titik tersebut akan diukur dengan receiver Trimble 5700 dan TSC1 controller. Data yang didapatkan akan dibandingkan dengan data yang didapatkan melalui receiver AgGPS 132 Survey boat positioning Dilengkapi dengan sistem GPS RTK Echosounder calibration Dilakukan sebelum dan setelah operasional untuk menentukan kecepatan gelombang suara aktual di area proyek. Kalibrasi dengan bar check (plate method)
Titik-titik control GPS akan diperiksa oleh company representative, party chief surveyor, dan contractor representative
