Craig McCall - Agency Supervisor

From the first time I met Tony French back in 2016 as he was in the early days of promoting and developing the RockSalt Subsea business I was more than impressed with his professionalism and passion for the company, services offered and safety. He kept close contact with us during the development stages and once everything was in place we were more than happy to use RockSalt Subsea ourselves and to promote them to our clients. We have had nothing but good feedback from the Captains of our vessels in particular how the operation has been carried out in a timely, safe and controlled manner. Since then we used RockSalt many times and have become our number one supplier for dive services.
