Integrated survey and inspection services — marine survey and rig positioning, geophysical surveys, pipeline inspection, and asset integrity assessments.
JST delivers integrated survey and inspection solutions across land, subsea, and aerial environments. By combining advanced technologies — including Drones, LiDAR, AI, and ROV systems — with field expertise, we provide accurate, reliable data and transform it into actionable insights that support engineering decisions and asset integrity.
Incomplete, inconsistent, or fragmented survey data creates risk across every phase of an asset's lifecycle.
Know the seabed. Place the rig with confidence.
Site and debris surveys, geotechnical CPT and vibro-corer, rig and barge positioning, anchor handling and rig move planning across Southeast Asia.
JST applies a four-stage methodology to ensure every survey and inspection programme delivers data that meets engineering standards.
Multi-platform data capture across subsea (ROV, sonar), aerial (Drone, LiDAR), and land (GPS, RTK) environments.
Transformation of raw data into high-resolution geospatial models and structured datasets.
Interpretation of survey and inspection data to identify risks, conditions, and performance indicators.
Validation through visual inspection, NDT, and field verification to ensure data accuracy.
Four integrated service lines covering subsea, aerial, land, and integrity disciplines — delivered as standalone services or as part of a multi-domain programme.
Site and debris surveys, geotechnical CPT and vibro-corer, rig and barge positioning, anchor handling, and rig move planning.
ExplorePhotogrammetry, LiDAR mapping, AI-assisted inspection, and aerial data acquisition for rapid, large-area coverage.
GPS and RTK surveys, well site surveys, and cartographic mapping for onshore projects and infrastructure planning.
Pipeline inspection, structural inspection, NDT, and integrity assessment support to manage risk and extend asset life.
Survey & Inspection works alongside JST's broader service offering — providing the foundational data layer that enables safe, well-informed operations across every discipline.
Marine and aerial survey programmes delivered for energy and utility operators across Thailand.
Submarine cable route survey for the 230 kV Khanom – Ko Samui Submarine Cable System Project. Data collected to support design and construction of the route from Khanom HV Substation to Ko Samui HV Substation, Surat Thani.
DTS and route survey for installation of the HVAC submarine cable system from Khanom HV Substation (Nakhon Si Thammarat) to Ko Samui HV Substation (Surat Thani), part of EGAT's 230 kV Khanom – Ko Samui Submarine Cable System Project.
Physical characteristics and geographic coordinate survey for 22 kV submarine cable routes: Khao Laem Ya – Koh Samet (Rayong, ~5 km) and Laem Ngop – Koh Chang (Trat, ~6 km).
Contracted UAV inspection of transmission towers, high-voltage line equipment, and right-of-way areas for maintenance planning. Coverage included the 230 kV Bang Saphan – Chumphon line (36.65 km, Prachuap Khiri Khan and Chumphon) and the 230 kV Thung Song – Khlong Ngae line (20.38 km, Phatthalung).
Marine survey and rig positioning, submarine cable route surveys, aerial and drone inspection, land survey and GPS mapping, and inspection support for pipelines and plant. Pipeline coating and cathodic protection surveys are delivered by the corrosion control team.
EGAT, PEA and J-Power submarine cable routes including the Khanom to Ko Samui 230 kV system, UAV inspection of EGAT transmission towers, and rig and barge positioning for operators in the Gulf of Thailand.
Multibeam and side-scan sonar, sub-bottom profiler, magnetometer, ADCP current meters, geotechnical CPT and vibro-corer, with DGPS and USBL positioning on JST’s survey vessel and chartered platforms.
