Offshore Construction Surveys
MHS provides a full range of services to support the offshore industry. We capability to perform rig site surveys, pipeline and cable route surveys, and pipeline monitoring surveys.
Marine Geophysical Surveys
MHS performs Geophysical Surveys for maritime/coastal engineering investigations and design, foundation and dredging assessments, submarine pipeline/cable route and monitoring surveys, and offshore structures/platforms/drill-rig locations.
MHS has developed a High Resolution 2D Marine Reflection Seismic (MaRS) System for use in medium to very shallow water to acquire higher resolution geophysical stratification and P-wave velocity data to a greater depth of penetration and through harder materials. MHS also operates 3.5kHz and 10kHz Pinger and Chirp Sub Bottom Profiling and 500Hz Boomer systems for projects requiring shallow penetration.
Seabed coring & Sampling
MHS can provide grab samples, shallow cores, vibro-coring and boreholes as well as sediment and core analysis.
MHS can provide short and long term gauging and analysis for the establishment of tidal planes and datums, datum transfers and determination of tidal constituents utilising fully submersible and shore based tide gauges and dedicated tidal analysis software.
MHS provides long and short term monitoring programs for assessment of impacts of coastal developments and mining on the environment including dredge plume monitoring, outfall monitoring, spills, river system discharge, seabed differentiation and sand resource investigation for reclamation, estuary and river management, channel and port siltation studies, coastal erosion and management, and tailings dam capacity and monitoring surveys.
MHS maintains a fleet of specialised survey vessels available for harbour or coastal deployment. Vessels of opportunity are utilised where necessary and our equipment can easily be transferred from vessel to vessel.
