Meteorology & Oceanography

Our network provides continuous monitoring of wind, waves, currents, temperature, salinity, and other critical parameters.

• Wave height and period predictions
  Using calibrated wave buoys, pressure sensors, and directional wave recorders, we collect real-time sea-state data. This information feeds into spectral wave models (e.g., SWAN, WAVEWATCH III) that forecast significant wave height, peak period, and mean direction hours to days in advance. Nearshore wave transformation due to bathymetry is accounted for to provide site-specific predictions at breakwaters, harbour entrances, and offshore platforms. Statistical analysis of long-term records delivers design wave heights (Hs, Hmax) and return periods required for coastal structure design. Daily, weekly, and project-specific bulletins give construction planners the reliable wave windows they need to schedule marine activities safely.
• Marine weather routing optimization
  Integrating global and regional atmospheric models (e.g., GFS, ECMWF) with high-resolution wind fields, we generate route-specific weather forecasts for vessel movements, towage, and offshore operations. Our routing algorithms consider wind, wave, swell, and surface current parameters to minimise fuel consumption, avoid heavy-weather zones, and ensure crew safety. Route comparisons are presented as a cost-safety matrix, showing ETA, fuel burn, and motion severity for each option. Real‑time updates via satellite communication allow shore-based teams to adjust routes as synoptic conditions evolve, making the service vital for critical deliveries, rig moves, and cable‑lay spread operations.
• Current speed and direction analysis
  We measure water column currents using vessel-mounted or bottom-mounted Acoustic Doppler Current Profilers (ADCP) and single-point current meters. The data is processed to produce current roses, depth-averaged vectors, and vertical shear profiles. Harmonic tidal analysis isolates astronomical tidal components (M2, S2, K1, O1) from non‑tidal residual flows, essential for predicting currents at any future date. Understanding local current regimes supports sediment transport studies, discharge plume modelling, navigation channel design, and mooring‑load calculations. Continuous monitoring campaigns capture seasonal variations and extreme events, providing engineering designers with robust current climatologies.
• Environmental condition reporting
  We compile comprehensive environmental baseline and operational reports that document metocean parameters throughout the project lifecycle. Temperature, salinity, turbidity, dissolved oxygen, and chlorophyll‑a data are gathered from CTD casts, multiparameter sondes, and satellite remote sensing. Reports include statistical summaries, time‑series plots, vertical profiles, and spatial maps. These documents support environmental impact assessments (EIA), permitting applications, dredge plume monitoring, and compliance verification. Regular condition reports during construction help project managers respond proactively to changing on‑site weather windows, ensuring operations remain within safe, environmentally compliant limits.
• GPR Detection Device
  For shallow sub‑surface investigations in coastal and transition‑zone environments, we utilise Ground Penetrating Radar (GPR) detection devices. These systems emit high‑frequency electromagnetic pulses into the ground or through water of low conductivity, capturing reflections from buried objects, sediment interfaces, and voids. In beach profiling, GPR delineates sand thickness, bedrock depth, and buried infrastructure such as outfall pipes or cables. In very shallow fresh or brackish water, low‑frequency shielded antennas can map sub‑bottom stratigraphy where acoustic systems may be ineffective. Data is collected on foot, with a small boat, or on tracked vehicles, and processed into radargrams and 3D depth slices. The technique provides a non‑invasive, high‑resolution survey method that complements acoustic sub‑bottom profiling and magnetometer surveys, especially in water depths too shallow for conventional geophysical vessels.
