Case Study

Commercial Diver Daniel Hammond 2 lo-resHSE Closed Bell – Daniel Hammond

‘I first heard about The Underwater Centre when I was training at DIT in Seattle and Alf Leadbitter (TUC Diving Operations Manager) came to give us a talk on HSE & IMCA.  Also, one of my instructors did his saturation course at The Underwater Centre and he told me that if I wanted to get into saturation diving to get my certification there.  Once I was working in the industry, I heard more about The Underwater Centre and its reputation as being a good training school.

Covers all bases

‘As far as the saturation dive training goes, it appears to cover all the bases to give you a great foundation to start your new career as a saturation diver.  The school has a great reputation within the industry, and to be honest I reckon you’d have to be stupid to go anywhere else, you’d just be shooting yourself in the foot as you get things here that you don’t get anywhere else, like the amount of bell bounces that you do and the amount of time you spend in the bell as opposed to other schools.  The instructors are top, brilliant guys; I’m training with Dad and Granddad that have been doing this for years.  They’ve done their time as divers and you can tell by the way they supervise.  They’ve been there and done what we’re going through so they know what’s in our heads.  And if you can teach physics in such a way that’s acceptable to a divers brain then you’re doing something right!  If I got a phone call tomorrow saying I’m getting blown down then I’d be pretty confident.

Getting into saturation diving

‘When I first got into commercial diving I always knew that I wanted to be a saturation diver, it fitted with my personality.  When I graduated from DIT I started working as a surface supplied diver for Neptune; it can be pretty overwhelming at the start and the learning curve is pretty steep so at that time I was focused on my surface career.  Saturation was always there in my head though, so after a while I started thinking more about building my dives to get onto the saturation course.  I was then on a job in the North Sea working from guys from Neptune’s Australian office, and they’d just done their saturation training at The Underwater Centre in Fort William, so I decided then that I wanted to focus on getting my HSE saturation ticket and working internationally.    I’m still working for Neptune at the moment, and a lot of divers are happy working in the Gulf, but now that I have the saturation ticket I hope my career will grow and I’ll get to see how the other half do it.  It’s more difficult for American divers to get work outside America, but with the HSE certification I should be able to now.  Neptune is growing internationally as a company though so I’d like to come back and work for them as they grow.’
