Case Studies

Here you can read details of some of the assignments we have completed over the past few years.

Hydrographic surveying

Detailed surveying of the seabed and underwater structures is essential in the management of oceans and the acceleration of the offshore energy transition. Sea Ranger Service has developed a low emission approach to carry out hydrographic surveying - to existing industry standards.

Seagrass restoration

Seagrasses are flowering plants that grow in coastal zones and support marine biodiversity, as well as absorbing carbon. We train and employ Sea Rangers full-time to actively carry out large-scale seagrass restoration in The Netherlands and France.

Drone inspections

To enhance maritime safety and accelerate aerial monitoring for conservation purposes, the Sea Ranger Service ran a series of drone tests from its offshore vessel in collaboration with Dutch government agency drone pilots.

Chlorophyll tracking

As seas are warming as a consequence of climate change, the distribution of nutrients in the oceans such as chlorophyl, is changing. Sea Rangers have been contracted by a Dutch governmental agency to sample chlorophyll in the North Sea.

Data insights

The Sea Ranger Service works with industry partners to strengthen its offshore and nature restoration assignments through advanced data applications including information from satellites. From dark vessel monitoring to underwater surveying and seagrass distribution - data insights assist Sea Rangers daily.

Wreck monitoring

Ship wrecks and ocean biodiversity are strongly linked. As well as the need to protect some of the historic wreck sites as valuable cultural heritage, shipwrecks provide a safe habitat for underwater plant and animal life and as such, their preservation conserves ocean biodiversity.

Plastics research

As microplastics can be found polluting seas and oceans globally, Sea Rangers work alongside a Dutch marine research institute to take samples in the North Sea to identify how pollution affects the marine environment.
