Survey Platforms

SEP Hydrographic offer a range of survey acquisition platforms, ranging from UAVs and ASVs through to our survey vessel 'Pulsar.'


Pulsar is a shallow drafted Cheetah Marine catamaran launched in 2006, and fully refitted during 2018 and acquired by SEP Hydrographic in May 2020.

Seafast Don

The Seafast Don is a 23-metre lightweight aluminium catamaran providing a stable, flexible platform for geophysical survey campaigns.

Unmanned Surface Vessels (USVs)

USV platforms provide an additional survey option to enhance acquisition productivity, or for locations where traditional vessel-based surveys are either unsafe or cost-prohibitive

Unmanned Aerial Vehicles (UAVs)

We offer a range of UAV acquisition options either to supplement vessel-based surveys or as a standalone campaign.


We offer observation class ROV services to provide a visual inspection of underwater assets.

Static Acquisition

Our scanning sonar and laser scanner can be mounted on a tripod or suspended from a crane
