Class IV 30 Meters Scuba course is the starting point of the commercial divers training. This scuba qualification is used by the Police Force; Fire Department; various rescue teams; Marine Archeologists; certain Aqua Culture divers; Media Divers and Scientific Divers. Scuba is the start of basic training for the professional diver using surface supply.

This qualification limits the diver to Scuba diving using small hand tools and conducting simple inspections where no decompression is required with direct access to the water surface. The diver may not operate large surface-controlled power tools, or dive where the use of cranes, air lifts, diver dredging or winches are required.

Animashaun Musa Bolarinwa

Surveyor, Geodetic Offshore Services Limited, Africa

"The Subsea Survey, Systems Positioning and Metrology (SSSPM) Level 1 & Level 2 training was very enlightening and insightful. It expanded my knowledge of Underwater Acoustic Positioning and Subsea Metrology. I appreciate Chess Subsea for putting up such educative platform while utilizing highly experienced facilitators and cutting-edge resources."

Edward Oluwasegun Oyelade

Trainee Data Processor / Geophysicist, Africa

"Through the SSSPM Level 1 & Level 2 training I was able to connect a lot of my previous knowledge of seabed survey and the gas industry into a big picture of how they operate. I was adequately introduced to metrology with patient description of subsea facilities, the metrology process, terms, and industry standards. I was also exposed to aspects of systems positioning systems new to me. As an aspiring geophysicist, I can say for sure that I have become more knowledgeable of subsea activities."

"I just completed the Natural Gas Engineering Production Process (NGEPP) Level 1 & Level 2 and I must say it has been an insightful experience and a great opportunity to learn new things. My tutor was very thorough with the course outline, his explanation was comprehensive and I really loved how he supported each topic on the course outline with videos in order for to grasp a virtual view of all the processes involve in natural gas processing."

Adelina Adao

Gas Engineer, Betchel, Angola, Africa

"I found the Natural Gas Engineering Production Processes (NGEPP) Level 1 & Level 2 interesting, challenging, and rewarding. I learnt a lot by following the course set out including Oil and Gas Seperation, Gas Dehydration, Petroleum Gas Compression, Natural Gas Liquid Recovery, Oil Pumping and Metering & Water Injection. Assignments were corrected quickly, with lots of positive feedback from the tutors."
