The HSE Closed Bell qualification allows you to work at various depths using oxygen and helium breathing mixtures (mixed gas) and saturation techniques.  Taught by saturation divers with decades of experience, the HSE Closed Bell training at The Underwater Centre will allow you to take your commercial diving career to the next level.  Due to the high levels of competency taught during training, the HSE Closed Bell certification is also accepted globally, so you can progress your career anywhere in the world.  The HSE ticket is also valid for life, so you won’t need to renew it at any point.

To attend the HSE Closed Bell course you need to meet certain pre-requisites; you must have logged 100 dives. For full details of the experience you need to have as an air diver before attending the mixed gas course, click here or email one of our Student Advisors who will be able to answer any questions you have – [email protected]

This course contains numerous bell bounces, including dives to 100m. At 3 weeks long, you won’t have to take a lot of time out of your working schedule to get the certification, and because everything is on one site in Fort William – with our deep dive site only minutes away from our pier – you don’t waste any time travelling when you’re on course, making the most of the time to learn and prepare for the job.

This course includes classroom based lectures and practical experience working with a real saturation diving system, with fellow students in training. Our ALST course is the only one in the UK where you can work on a real closed bell diving system, handling gases used in diving, giving you invaluable experience on the job. The course covers physics, physiology, legislation and dive system requirements, covering the IMCA requirements for an introduction to this highly responsible support role.

This is an optional course, with extra tuition during the decompressions; let your instructor know you want to complete this training at the start of the HSE Closed Bell Course.

At least one member of every offshore dive team is required to be trained in advanced first aid, so the availability of high-standard Diver Medic training is paramount. Designed to give you relevant, practical experience and knowledge to make you more employable in the subsea industry, this two week course incorporates hands-on training delivered by extensively experience diver medical practitioners.

You will need to return to The Underwater, Fort William to complete this course, at a mutually convenient time and within one year of completing your HSE Closed Bell Course.

The SPHL which we now have on site here in Fort William was recently donated to us thanks to the close links we have with key contacts in the subsea industry. Industry recognises the importance of ensuring that the training we provide keeps up with current industry practice, so when students leave us they are familiar with key lifesaving equipment.

The new practical introduction to using an SPHL adds to the existing classroom-based lectures by providing first-hand experience of entering and existing an SPHL. It also familiarises students with the limited space available in an SPHL – reducing the unknown factor of using an SPHL, should the need ever arise when working offshore.

For divers that haven’t come across the equipment before this practical introduction to bolt tensioning provides you with the knowledge and understanding of working with and using bolt tensioning equipment; a sought after skill for diving personnel.

Thanks to Stork Technical Services for the donation of the equipment to enable us to run this introductory course.

Kirby Morgan Helmets are widely recognised all over the world as the standard in commercial diving equipment.

When working as a commercial diver, the company you are working for will provide the helmet for the job, however your employer will expect you to be able to competently perform inspection, set-up and operation procedures.
This course will train you to Kirby Morgan standards to identify equipment deficiencies and perform corrective adjustments and minor servicing of the hat, and efficiently mobilise and de-mobilise the equipment at the start and the end of each dive, ensuring that your new employer can have complete confidence in your care of their equipment. On completion of the course you will receive a two year certification from Kirby Morgan (USA).

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.’
