Mobile
Diving Unit
 Pro-Dive Marine
Services is pleased to offer its fleet of self-contained Mobile
Diving Units. These units are Ford Econoline Cube Vans that
have been modified to incorporate a full surface air diving
system thus capable of completing any inshore diving operation.
As one of the finest mobile units in Atlantic Canada, it contains
both a dive control / viewing room, and a separate equipment
area. From the dive control area, all diving operations are
monitored and videotaped by the diving supervisor. Full control
of lighting, diver communication and a two-diver air panel are
features of this area.
The rear equipment area contains tools and necessary equipment
to complete inshore work or on-site equipment repair. There
are two-300 feet diving umbilicals complete with camera, video
cables and lights. The two-diver systems utilize state-of-the-art
Kirby Morgan Superlite diving helmets, the industry standard
for Commercial Diving. Similarly, this system is ideal for a
single diver system with a surface supplied stand-by. This system
is also interchangeable to provide both dry suit or hot water
suit capabilities and can provide umbilicals up to 600 feet
in length.
Containerized Surface Air Diving System
For deep air diving operations, where chambers on site are critical, Pro-Dive uses their self-contained unit in a 2.4 by 6.0 meter containerized system complete with:
- 60" double lock decompression chamber
- 3 diver mixed gas panel
- Quincy 5120 air compressor
- 2 x 600 feet fibron umbilical
- DSI hot water system
Air Lift Bags
In situations where insufficient water depth precludes the deployment of parachute type lifting bags above the object to be raised, an effective alternative is the use of a cylindrical totally enclosed lifting bag.
Lifting bags can be secured closely to the article or shackled to straps passed underneath it. Totally enclosed lifting bags offer an invaluable method to reduce the draught of vessels when launching, slipping or maneuvering them in limited depth. They can also be employed as pontoons for bridges, floating platforms, dock gates and military equipment.
The lifting bags also provide an ideal form of buoyancy for cable or pipeline float-out operations and are extremely stable undertow. No other floatation aid can be folded away so compactly when not in use.
All totally enclosed lifting bags are fabricated from heavy-duty Trevira cloth coated with PVC. A heavy-duty load restraint harness of polyester webbing is built into the skin of the air bag and has a safe working ratio of 6:1. The arrangement of this load restraint harness is specifically designed to maintain the air bag in the horizontal position to ensure maximum stability and lifting effort.
All models have ¾" BSP air inlet ball valves with kamlock quick release hose line fittings. Pressure relief valves are also incorporated at the bottom of the air bags and are automatically set to function at 2 PSI above ambient with flow rate in excess 80 CFM.
Pro-Dive Marine Services now offers a full line of Hull Cleaning and Propeller Polishing Services
A rough hull condition can result in a power loss of up to 12%. For example, a vessel with a rough hull, that consumes $5000.00/day in fuel, can potentially save several hundred thousand dollars per year. This combined with delayed delivery time due to the resulting slower cruising speeds can have extremely negative consequences to the bottom line.
It has also been proven that propeller roughness can result in power loss up to half that of a rough hull, a full 6%. In terms of surface area, the reward versus expense for cleaning a propeller is amazing.
Given the escalating cost of fuel, hull cleaning and propeller polishing is the quickest, cheapest, and most efficient method of increasing profit margins for ship owners.
Pro-Dive Marine Services offers a full range of hull cleaning and propeller polishing equipment to service the requirements of any size vessel. The equipment includes:
