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.

Mersey Discovery

Mersey Discovery is a 11.5m Redbay RIB with a shallow draft and a wide and fully enclosed wheelhouse making her ideal for nearshore survey operations.

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
