Side Scan Surveys
Masirah International provides Side Scan Survey Services for its clients. This survey is required for big projects and specifically for subsea construction projects. Generally Side Scan Surveys are done for identifications of objects lying on seabed and for condition reporting of sunken vessels.

Side Scan Survey work requires extreme understanding of sea weather, Vessel Tracking along with Excellent computing skills by the surveyor. Our experts guide us to get the best results by employing the methods devised based on project needs. Masirah International recently completed a Side Scan Survey job in Musandam

Sub Bottom Profiling Surveys
Sub-bottom profiling systems identify and measure various marine sediment layers that exist below the sediment/water interface. High-resolution sub-bottom systems have been used to detect and measure the thickness of dredged material deposits, detect hard substrate that has been covered by sedimentation, identify buried objects (such as cables and pipelines), and define the basement (or bedrock) layer for potential confined aquatic disposal sites for dredged material. Sub bottom Survey is more than just marine investigations. This requires excellent knowledge of using multiple sonar with vessel tracking parameters in control. We have successfully completed a recent Sub Bottom Profiling Survey job in Musandam.

Topographical and Land Surveys
Masirah International provides services of Topographical and Land Surveys as well. Our experienced survey team is capable of working onshore and inland. The topographical survey team generally supports our bathymetric survey team and field operations team during construction projects. The survey services onshore and inshore can be provided to clients as well on demand from the client. We have latest equipments like Leica Total Station and Leica Dumpy Level and we are capable of providing data in any required format by the client within accuracy limits.
Tide recording and Data Analysis
Masirah International Engineering and Planning division is capable of tide recording with our up to date Valeport Tide Master 740 Tide Gauge. The tide gauge data acquisition is done for numerical modeling and for analysis of field data in order to incorporate this data with deisgn calculations. The tide gauge setup is a skilled and specialized job and our special equipments are capable of providing the best data to our clients.
