Survey Vessels
CERES deploys its hydrographic survey vessels and marine assets for maritime and subsea operations.
CERES III Catamaran






CERES III supports both short survey assignments and longer, more demanding operations. Its rapid mobilisation helps the team make effective use of suitable weather windows, especially in areas exposed to wind and swell. Sea conditions are a key consideration for geophysical and geotechnical surveys.

SIRIUS IV SURVEY VESSEL
SIRIUS IV is the latest vessel acquired by CERES. It is primarily dedicated to water sampling and UXO surveys, both offshore and on rivers and lakes. Its speed enables rapid deployment to the areas selected by the operator.




SIRIUS IV provides a sheltered working environment at sea, protected from spray, allowing the IT equipment required for the various survey missions to be installed safely. Particularly stable, SIRIUS IV offers long endurance through its fixed aluminium fuel tank and additional tanks. A dedicated ladder facilitates diver access to the water.
