Independent LBL array analysis

Technical assessment for proposed and existing LBL and Sparse LBL arrays—from transponder placement and acoustic coverage to degraded configurations and practical operational recommendations.

01

Array planning

Assessment of proposed transponder locations against the work area, bathymetry, operational constraints and required coverage. Alternative positions can be considered where the initial layout leaves important areas exposed.

02

Geometry analysis

Evaluation of range availability, transponder intersection angles and how LBL geometry changes across the work area, route or at specific points of interest.

03

Positioning performance assessment

Estimation and visualisation of expected positioning performance based on documented inputs and assumptions. This is an engineering estimate, not a guaranteed field result.

04

Line-of-sight and terrain assessment

Use of bathymetric or terrain data to identify potential acoustic obstruction between the subsea vehicle and each transponder, including changes with vehicle height above seabed.

05

Degraded configuration analysis

Assessment of how coverage, geometry and expected performance may change if one or more transponders become unavailable during the operation.

06

Independent review

Manufacturer-neutral review of array plans or analyses prepared by a project team, equipment supplier or contractor, with assumptions and limitations made clear.

07

Operational support

Practical recommendations for deployment, calibration, verification and use of the array, aligned with the analysis and the stated operational constraints.

Scope built around the operation

Useful outputs, stated limitations

An assessment can focus on a complete work area, a route or alignment, or selected points where positioning is particularly important. Outputs are selected to communicate the findings clearly to survey and project teams.

Analysis is based on supplied information and stated assumptions. Actual offshore performance may be affected by calibration quality, acoustic conditions, sound velocity, equipment configuration, noise, multipath, line of sight and operational conditions.
