Commercial divers are trained for the occupational environment by going through four months full time or five (5) months of part time theory and practical classes and logging over 650 hours of surface-supplied diver training.

SURFACE SUPPLIED DIVING is where divers receive their primary air from the surface; it is different from scuba where the divers actually carry their air supply on their back. With surface supplied diving, the divers have three back-up air supplies and communication to the surface, where the supervisor is able to monitor the air supply, depth and time of the diver. With scuba, the diver is responsible for monitoring his own air suply, depth and time under water.  

UWIL offers a wide range of commercial diver training courses. Our enrolment details, diving pre-requisites and course descriptions, together with all applicable costs are listed below.


Upon enrolment, all students are required to: 

1.      Fill out and sign the Commercial Diving Enrolment Agreement and liability forms.

2.      Complete a fit-to-dive medical from a recognized hyperbaric physician.

3.   Have all relevant personal equipment required for the practical classes: wetsuit, coveralls, small dive light, dive watch, wrench, steel tip boots, diving boots, gloves (3mm), fins, mask and dive knife. These items are also available for purchase from UWIL. Please see the section on Scuba Diving for pricing details. DO NOT BUY NON SCUBA DIVING EQUIPMENT ie Snorkeling equipment.


Before enrolment, all students MUST have completed the following:



UWIL offers these certifications for students. Note: we do not accept any certification  from any other training institute as proof that you can do the dives.  If you already have an open water certification you are required to do 5 dives with us to show your competency. If you are currently advance, rescue or dive master certified from another institute you will be required to do  5 dives over 3 consecutive days i.e deep diving to 120ft, night diving, boat diving and  2 drift diving with us before acceptance in the course. The cost of these dives will be additional. Please see the section on Scuba Diving for details and cost.

The Trinidad and Tobago Bureau of Standards is preparing to launch a National Commercial Diving Standard that conforms to the OSHA requirements for the industry. One of the requirements of OSHA is that all commercial diving companies MUST have all their divers certified by an  approved certification body. This will mean that once the National Commercial Diving Standard is enforced, OSHA inspectors will be able to shut down all operations that are conducted by divers who do not have the recognized international commercial diver certification and who are not following the national standards in their operations.

We at UWIL are presently offering a number of commercial diver training courses. On successful completion of the theory exams and logging of the required dive times and depth, we will apply for the certification cards. Students are expected to find at UWIL, the same intense training that can be found in any school outside the Caribbean.
