Standard Subsea

Software for
marine work.

We built Contour to keep assignments, mission recordings, surveys, findings and deliveries together. Each visit adds to the site’s record.

Surveys:
Source & method

All four views show the same 1,152 × 816 m footprint, using the delivered survey coordinates. MBES uses numerical 1 m depth grids from Pre-construction and Post-construction, with a shared palette and lighting. Unsurveyed cells remain empty.

Both side-scan views use actual georeferenced survey mosaics: 1 m in Pre-construction and 0.5 m in Post-construction. Amber and display contrast are applied to reveal texture. Sonar brightness is not calibrated between surveys and is not a measurement of change.

Survey source: Emu / Fugro via Marine Data Exchange. Demonstration using published surveys. Pre-construction source ↗ · Post-construction source ↗

ASSIGNMENT & DELIVERY / ILLUSTRATIVE

The assignment
and its delivery.

The scope defines what is needed. Findings retain the evidence. The delivery records exactly what was handed over.

ASSIGNMENT

Seabed survey

Scope
The selected 1,152 × 816 m area around the structure.
Required evidence
Bathymetry, side-scan and a comparison with the earlier survey.

DELIVERY RECORD

The reviewed handover

A delivery identifies the exact products and revisions handed over. Later edits do not rewrite that record.

Capture an example handover

Keep a snapshot of the current evidence and review question. Further edits leave that snapshot unchanged.

Snapshots stay in this tab until it is closed or reloaded.

What explains the profile difference at the structure?
