Diving equipment and Working boats |
All diving operations are performed by their own special diving equipment, and depending of the depth at the performance of stages of diving diving, we apply technology of air diving or on gas mixture nitox or trimix.
DIVING EQUIPMENT * High-pressure compressor with air bank 300 bar
* Hydraulic Power Unit
* Pumps (mammoth) for underwater excavation (water, air and hydraulic systems)
* High pressure water pump 500 bar
* Diving equipment: external supply with a diving helmet, an autonomous equipment (air mixtures: NITROX, TRIMIX)
* Devices for underwater communication: wired and wireless
* Underwater digital camera system with monitor and with image transfer to the surface (internal TV) + system to capture images direct to DVD
* Various lifts for lifting cargo: parachutes, cylinders...
* Low-pressure compressor with associated tools - pikameri, drills, air mammoth
* Hydraulic power unit with associated tools for underwater works: drills, saws, pumps, measuring instruments...
* Trucks, vans
    
    
WORKING BOATS Motor boat "MB Jadrija" is used as a mother ship for performance. Also, if necessary, as the auxiliary and ancillary are used diving boats and powerboat boats.

Underwater surveys and underwater works |
The company "NEPTUN - SUB" Ltd. specializes in performing works of diving and underwater diving inspection techniques with robotic technology (ROV - remotely operated vehicle):
UNDERWATER INSPECTIONS
1. Underwater inspections, recording videos and photo cameras shooting with image transfer to the surface for inspection of underwater installations, ports, bridges, boats...
2. Finding, inspection, mapping of cables, pipelines and related subsea installations
3. Underwater inspection of hazardous locations for divers (hydropower stations, containers...)
4. Offshore activities in the oil and gas industry:
* Visual inspection of platforms structures and subsea pipelines
* Positioning underwater pipelines
* Measurement of cathodic protection
* Measurement of wall thickness
* Assistance in assembling oil platforms and other infrastructure
5. Search and locate sunken objects after a maritime accident
6. The study of archaeological, biological and geological points of interest at the bottom of the sea
    
UNDERWATER WORK All phases of diving works are recorded if needed on internal television and communication system which allowing maximum safety for divers and an insight into the performance of all phases of diving work:
* Construction and repair of submarine outfalls, cables, pipes...
* Installation, maintenance and repair of mooring systems, marinas, ports and harbors...
* Repair, renovation, cleaning and maintenance of hydroingeneering, ships, offshore structures...
* Diving intervention in disasters and accidents at sea
