Service Overview

PRECISION CALIBRATION
FOR THE REGION

Sea and Land Technologies provides regional calibration support for AML Oceanographic instrumentation used by hydrographic and oceanographic operators across Southeast Asia and Australia.

As part of SALT's after-sales support capability, the service focuses on maintaining measurement accuracy and minimising instrument downtime for critical survey operations. With its regional support base in Singapore, SALT helps customers reduce service turnaround time and maintain confidence in critical ocean measurement systems.

AML's X2change™ architecture stores calibration coefficients within the individual sensor head, allowing recalibrated sensors to be swapped directly into the instrument without returning the full unit — significantly reducing logistics time and keeping operational systems available for field use.

X2change™ Sensor Heads

SUPPORTED SENSORS

SALT supports calibration of AML's field-swappable X2change™ sensor heads. Each sensor head stores its own calibration coefficients, enabling rapid swap-out without returning the full instrument.

SV
Sound Velocity
Primary parameter for acoustic positioning and beam steering. Annual calibration recommended to maintain bathymetric accuracy.
SVT
Sound Velocity & Temperature
Combined measurement sensor. AML recommends calibration intervals of up to two years for SVT sensors depending on operating conditions.
T
Temperature
Critical for sound velocity calculation and oceanographic data quality. Accurate temperature measurements underpin water column interpretation.
D / P
Depth / Pressure
Essential for accurate depth referencing in hydrographic surveys. Pressure sensor calibration directly influences water depth reporting and ray tracing.
Logger
Logger-Integrated Packages
Calibration support for complete logger-integrated sensor packages used in profiling, mooring, and AUV-deployed configurations.
Calibration Capabilities

WHAT SETS OUR SERVICE APART

SALT's calibration service is built around reducing turnaround time, maintaining data integrity, and keeping your survey operation running without unnecessary disruption.

01
Fast Regional Turnaround
Singapore-based calibration hub means dramatically shorter logistics cycles compared to shipping instruments to overseas OEM facilities. Less downtime, more survey days.
02
X2change™ Sensor Architecture
Calibration data is stored within the sensor head — not the logger. Recalibrated heads swap directly into your instrument in the field, keeping the main unit operational throughout the service cycle.
03
Traceable Measurement Standards
Calibration procedures follow AML-specified methodologies and traceable reference standards, ensuring results are defensible for government survey contracts and audit requirements.
04
Local Technical Support
SALT's team provides in-region technical assistance alongside calibration — including instrument health checks, firmware review, and operational guidance for AML users across the region.
05
Scheduled Calibration Programmes
SALT can manage annual or multi-year calibration schedules for fleet operators, ensuring sensors are always within their recommended calibration window and ready for mobilisation.
06
Calibration Certificates
Full documentation provided with each calibration, including calibration coefficients, uncertainty estimates, and equipment traceability records suitable for project and audit submission.
Why It Matters

CALIBRATION ACCURACY IN SURVEY OPERATIONS

For hydrographic and oceanographic operators, accurate sensor calibration is not a routine formality — it is the foundation of data quality across every mission parameter.

Survey Data Quality

  • Multibeam bathymetry accuracy — sound velocity errors propagate directly into depth and position measurements
  • Beam steering and acoustic ray tracing — correct SV profiles prevent systematic swath distortion
  • Sound velocity profile correction — real-time and post-processed SVP quality relies on calibrated sensors
  • Water column interpretation — temperature and depth data quality affect echo analysis and target characterisation
  • Oceanographic data quality — scientific repeatability requires calibrated, traceable measurements
  • Repeatable scientific observations — long-term monitoring programmes demand consistent instrument performance

Operational Impact

  • Reduced re-survey risk — calibration failures discovered post-acquisition can require expensive remobilisation
  • Compliance with survey specifications — IHO, LINZ, and national hydrographic standards require calibrated instrumentation
  • Asset lifecycle management — scheduled calibration extends sensor serviceability and identifies degradation early
  • Insurance and liability — documented calibration records support project indemnity and client acceptance
  • Fleet availability — X2change™ swap-out architecture means sensors can be calibrated without removing the logger from service
  • Mobilisation confidence — pre-mobilisation calibration checks eliminate sensor-related start-up delays
