Are the submersibles classed?  
Yes, all SEAmagine submersibles are classed +A1 by the American Bureau of Shipping (ABS) and can also be certified by US Coast Guard or by the Cayman Island Shipping Registry (CISR). During the construction of each submersible, ABS surveyors inspect all key aspects of the construction, survey all functional test of the various systems and witness the sea trials, which include the final test dive to the submersible’s maximum operating depth.  |Top|

How long does it take to build?  
As a baseline SEAmagine’s 2-person Ocean Pearl model delivery if 18 months while the 3-person Triumph Model delivery is 24 months.  |Top|

What is the weight of the submersible?  
SEAmagine’s smallest submersible is the 2 Person Ocean Pearl model with a dry weight of 7,100lbs  while SEAmagine’s largest submersible is its 3 Person Triumph model with a dry weight of 15,500 lbs. |Top|

What is the size of the submersible?  
SEAmagine’s smallest submersible is the 2 Person Ocean Pearl model:  

Length: 14 ft, 10 in (4.53m)   
Width: 8 ft  (2.44m)
Height with Cabin Closed:  7ft, 8 in (2.34m)

SEAmagine’s largest submersible is its 3 Person Triumph model:

Length: 17 ft, 6 in (5.33m)
Width: 10 ft, 2 in (3.11m)
Height with Cabin Closed: 9 ft, 10 in (3.00m)

How is the submersible launched?  
SEAmagine’s submersibles have a four point hoisting arrangement for launching. SEAmagine’s Triumph model also has the option for a single point hoist. Since SEAmagine’s submersibles have a patented buoyancy system that permits them to float high above the water line when on surface, the operator launches the vessel with no occupants on board. The launch and recovery of SEAmagine submersibles is performed unmanned, reducing the cost of the handling system since the cranes are not required to be “man-rated” which would involve far greater safety factors and larger equipment.

Once launched, the external controls on the submersible allow a pilot to drive the submersible on surface as any tender and dock the craft to the dive deck where it is tied off and then prepared to receive its crew.  |Top|

Are there special Flag-State requirements for submersibles?

Yes, most Flag State agencies will require some proof that the submersible will be operated safely in their waters. Most state flags do not have special submersible requirements but will generally require that the submersibles be classed by an internationally recognized classing society such as ABS (American Bureau of Shipping). Other Class societies include Lloyds Registry (LR – United Kingdom), Det Norske Veritas (DNV - Scandinavia), Germanischer Lloyds (GL - Germany), Bureau Veritas (BV - France), (RINA – Italy), which all belong to the International Association of Classing Societies (IACS).

 

The Cayman Islands Shipping Registry (CISR) is one of the exceptions and they do have additional requirements regarding the submersible operation in addition to those of the classing societies. These additional CISR requirements are readily addressed during the construction of the submersibles.

US Flag State have specific requirements if the submersible is to be used for “passengers for hire” in which case the US Coast Guard requires additional vessel inspections and technical reviews above ABS or other classing societies. For private use, the US territory does not have specific requirements. French flag state also has specific submersible requirements in addition to the classing societies.   |Top|

How much oxygen must be carried and how is it stored?  
The submersibles do not consume large quantities of oxygen in their life support system. SEAmagine submersibles all have a main oxygen supply and a reserve oxygen supply as backup. The main oxygen tank must be replaced after 30 to 32 hours of cumulative diving. The oxygen tanks are regular 120cuft (15L) oxygen cleaned SCUBA tanks that are certified for transport and are easily stored. The ship can carry a number of oxygen filled 120cuft (15L) tanks that can be swapped out when at sea and refilled at the next harbor stop over. As an example, for an ABS classed submersible, 6 full spare tanks will provide in excess of 180 hours of cumulative diving before they need to be refilled.

The oxygen used on the submersibles is medical oxygen and the tanks are stored in a protected environment as any medial oxygen.   |Top|

What do I need to organize on the ship to accommodate a submersible?

There are a number of aspects that need to be taken into account for integrating the submersible onto a ship:

  • Proper Electrical AC power for the submersible’s battery charger

  • Proper rated crane/handling system for launch and recovery

  • Sufficient storage area for spare parts

  • High-pressure air compressor for refilling the submersible air tanks

  • Storage area for high pressure air and oxygen tanks

Every ship has some differences. SEAmagine’s engineering department is highly experienced and will assist to provide the necessary support for helping determine each ships integration requirements.   |Top|

How Can I best refit or redesign the ship to accommodate the submersible?
The best first step when looking into the redesign or refit of an existing ship is to first contact SEAmagine’s engineering department. There are a number of aspects to consider and SEAmagine’s extensive technical knowledge is an important source of knowledge on available options. In many cases some adjustments on the submersible is possible to simplify the integration on an existing ship design.  |Top|
