PROVIDING THE HIGHEST SAFETY FOR EACH SMALL SUBMARINE

ALL OUR PERSONAL SUBMERSIBLES ARE CLASSED BY THE AMERICAN BUREAU OF SHIPPING (ABS) OR DNV-GL

FORMAL CLASS APPROVAL

WHAT IS CLASSIFICATION APPROVAL

Each SEAmagine small submarine is approved and classed individually A1+ by either the American Bureau of Shipping (ABS) or by DNV-GL which are international non-governmental organizations that establish and maintain technical standards for the construction and operation of ships, submersibles, and offshore structures. These classification organizations verify and validate that the construction of each small submarine is according to their standards by carrying out regular surveys during the fabrication and testing phase and by performing annual field surveys once the small submarine is in service.

The formal classification approval ensures that high industry safety standards are met by each individual submersible and it also ensures that owners can procure adequate insurance from underwriters to cover the small submarine after delivery.

SUBMERSIBLE CLASSIFICATION PROCESS

The classification approval process involves numerous steps by the classification society which is executed on each small submarine individually. First, the submersible design with all its features and safety requirements are analyzed by the classification’s engineering department to concur that it meets all formal standards and approved requirements. Following this engineering design approval of the submersible, ABS or DNV-GL surveyors will perform numerous inspections during the fabrication to witness adherence to the approved engineering drawings and also witness all formal material and pressure testing milestones. The submersibles are designed to withstand multiple times their maximum depth rating and are physically pressure tested to higher pressure values than their maximum operational depth. Upon completion, each small submarine undergoes numerous operational tests surveyed by classification society inspectors who verify that all normal systems and emergency systems function as designed. Finally, a formal test dive to the maximum depth rating of the small submarine is performed on each submersible with a surveyor. After inspection, surveys, and tests have been successfully completed, the classification society issues a Classification Certificate for that specific small submarine.

 


MAINTAINING CLASS STATUS ON EACH SMALL SUBMARINE AFTER DELIVERY

The submersibles are delivered to the clients with a Classification Certificate ensuring that each small submarine was built and surveyed to the approved code. This Classification Certificate needs to be maintained active after delivery and each submarine must undergo a formal survey by an inspector from the classing society once a year.

The normal annual Classification Survey can be done on deck and typically involves assessing the vessel’s state and testing all emergency systems on the small submarine. A checkout dive is typically not required on a normal annual survey if the submersible has performed at least one dive within the previous 12 months. SEAmagine typically coordinates its engineers to perform their annual preventive maintenance on the small submarine in coordination with formal Class Annual Survey period and the company then helps clients handle the annual survey process.

Every three years the Classing Society requires a Special Survey which is more in depth and reconfirms all systems, calibration, and also requires a test dive with the surveyor to the maximum depth rating. Again, SEAmagine’s technical support program helps the clients handle the special surveys.

SOLID DESIGNS AND A LONG HISTORY ENSURING SAFETY

SEAmagine has a long history and its submersibles have accumulated over 12,000 logged dives around the world with an excellent track record in reliability and perfect safety. We do not simply concur with the classification standards but surpass them with key features to enhance operational safety and practicality. In addition, SEAmagine’s proven training program and comprehensive technical support ensures that the small submarine operations follow proper protocol by a trained crew and produce an overall safe system of operation.
