Introduction
Aquatic Conserver was designed as a multipurpose vessel in order to be cost effectively engaged in various purpose as listed below.
• Harbour survey: This survey is intended for the safe navigation of vessels near ports and their surroundings.
• Passage survey: This survey is intended for safe navigation in main sea lanes.
• Coastal survey: This survey is intended for safe navigation and gaining knowledge about the bottom topography, sea-bottom sediments, and more in offshore waters.
• Survey for correction: The survey for correction (general hydrographic survey) is designed to measure water depths, coastlines, and geological features after dredging, artificial fish-reef installation, and such, and change waterway related publications such as nautical charts accordingly.
The vessel has been designed to operate at ultra-low creep speed on only one (1) knot in any direction of current with hydraulically controlled pumpjet.

• Environment control:
Deployment of oil boom to restrict the spread of major oil spill.
Deploy oil skimmer to recover spilled oil into vessel’s recovery oil tank specially approved for flash point <60deg C.

• Pollution control: Spraying dispersant in case of minor oil spillage.
