Independent subsea positioning analysis

Understand your LBL array before going offshore

Independent analysis of LBL and Sparse LBL array geometry, coverage and expected positioning performance for subsea operations.

Decisions before deployment

See the strengths and limitations of the array

LBL Insight helps project teams evaluate whether a proposed acoustic array is suitable for the intended operation. Clear analysis supports better-informed technical discussions before mobilisation or installation.

01

Geometry limitations

Identify where transponder geometry becomes weak or poorly balanced.

02

Range coverage

Locate areas with insufficient acoustic ranges for the intended positioning approach.

03

Degraded operation

Understand how loss of a transponder could affect coverage and expected performance.

Typical applications

Subsea operations where geometry matters

LBL and Sparse LBL analysis can support route-based, area-based and point-specific operations.

Cable and umbilical installation
Touchdown monitoring
Subsea structure installation
Metrology support
ROV navigation
Inspection and intervention work
Sparse LBL operations
Pre-mobilisation feasibility studies

Basis of analysis. All results depend on the quality of supplied data, equipment performance, calibration, acoustic conditions, line of sight and the assumptions used in the analysis. Actual offshore performance may also be affected by sound velocity, noise, multipath, equipment configuration and operational conditions.
