What is a Commercial Diver

What is a Commercial Diver?

Commercial Diver

A commercial diver is the most common type of professional diver that works for pay. There are a number of different types of commercial divers but the most common is the offshore diver working in the oil and gas industry. Commercial divers are extremely skilled professionals. They often work in dangerous circumstances and require the proper training and certification necessary to meet regulations of the local authority.

At cDiver.net, we are striving to be the ultimate resource for commercial divers. The services and content on the site are there to assist divers in their lives. Whether it be searching for commercial diving jobs, networking with other commercial divers, being updated commercial diving industry news, or sharing content related to commercial diving like photos, videos, and blogs; cDiver.net is dedicated to providing an excellent network for commercial divers.

Types of Commercial Divers:


Offshore Diver

The most common commercial diver is the offshore diver working in the oil and gas industry. Here is where most commercial divers enter their professional career. The wages start out low but relevantly increase over time. They have difficult work schedules, working long hours with not many days off. The divers live on oil platforms or vessels for long periods of time. Many do not work year-round; due do the seasonal flow of work done offshore.

Inland Diver

Inland divers work on inland projects. Working on land based civil engineering operations done in lakes, harbours, rivers and dams. They do not face as many hazardous working conditions and living situations of offshore divers, but the pay is considerably less.

HAZMAT Divers

HAZMAT divers are considered highly skilled and experienced divers who work under dangerous conditions. They have to work under special circumstances due to the dangerous material they dive in, such as pollution and chemicals, as well as the very dangerous sewer diving. HAZMAT divers must take precautionary measures to deal with the threat of contamination.

Nuclear Divers

Nuclear divers work under conditions much like HAZMAT divers. Different precautionary measures are taken to prevent the exposure of radiation. They may use a cold water suit to prevent heat stress from contaminated areas.

Scientific Divers

Scientific divers study scientific data found underwater. They are scientists as much as they are divers, trained in both professions. The work is done both offshore and inland.

Media Divers

Media divers work in underwater filming and photography. They are trained camera operators who mostly cover projects meant for television documentaries and movies.

Military Divers

Military divers, also known as naval divers, do military operations underwater. This involves offensive and defensive military tactics. They also dues repair on military vessels and underwater equipment. Many move into different areas of commercial diving after they leave the military.

Police Divers

Police divers assist in police investigations where a diver is need to recover something underwater.

Cem Durgun : Underwater welding and Diving Instructor @ NYD - Norwegian Subsea Training Centre

Specialize in planning, executing, and supervising diving operations, alongside teaching the theoretical and practical aspects of diving, underwater welding, and oxy-arc cutting. With over 15 years of teaching experience, I have worked with both experienced commercial divers and those new to the field, ensuring they gain the necessary skills and knowledge for underwater welding. I believe teaching is crucial to the development of any diver, and I approach my role with a strong pedagogical mindset, recognizing the need to see and realize different approaches for each diver or student according to their unique needs. This ensures that each individual receives the support necessary to thrive while maintaining a solid foundation in safety and technique.

Cem's background includes five years of service as a Petty Officer in the Turkish Naval Forces, where I honed my skills in navigation, leadership, and operational management.


His mission is to share his expertise with the next generation of divers and welders, equipping them with the skills and knowledge needed for success, including advanced techniques like oxy-arc cutting. Cem is passionate about contributing to the continued development and innovation of the subsea sector.

Recently Nicole was selected to demo the DRASS ONE She commented: “I loved the experience. The helmet lets you move your head in every direction, and the wide viewport makes a huge difference compared to what I’ve used before. Demand is so smooth, almost like breathing on the surface, making it much easier to get the job done. Going forward, I will really enjoy working with this helmet.”

Magician / SAT Diver joins Commercial Dive Locker 2026 Board

Meet Edward Askham Spencer, DeepSea Saturation Diver, Internationally Renowned Professional Magician. Veteran of the 3rd Battalion The Parachute Regiment. Actor, Writer, Producer & Director of a fictional film series currently in preproduction.

Commercial diving engaged Edward's curiosity since he was a small boy and for over a decade has been his primary focus for earning an income. His first offshore job was in 2014. Being capable, qualified, fit healthy and flexible enough to work in this industry is far from easy to maintain but it is was his love for being in challenging environments.

Edward's secondary interest is Entertainment and more specifically performing Magic. Edward came late to Magic learning the basics in 2018 but quickly realized that it was a way to charismatically engage with people on an even footing. He has performed for his 2 year old right through to a 105 year old, penniless people through to hedge fund CEO’s, Celebrities and members of the Royal family. People of many ethnic backgrounds and cultures and every time the striking common reaction is the same, he us greeted with wondrous smiles laughter and applause. I love those moments when I put some normal everyday thing in front a person and they seemingly make a magical moment happen.

Ed Horn : Dive Superintendent Joins Board of Commercial Divers

 

Professional Motto
Precision – Safety – Execution
"I don’t just dive into projects—I lead purposefully, enforce structure, and deliver results that endure beneath the surface.
“Diving is not just depth and pressure—it’s discipline, readiness, and the trust that others place in you when the stakes are highest.”

I have a well-documented, 2-decades-long success record, managing high-risk underwater construction, salvage, inspection, and demonstration projects across military, industrial, and commercial environments. My career spans complex, compliance-driven work for U.S. Army Garrison operations in the Marshall Islands, utility giants like FPL and Tampa Electric, and high-visibility OEM demo teams pushing the edge of subsea technology.

From directing dam gate installations and hyperbaric chamber operations to guiding vessel salvage under emergency protocols, I bring structure to high-consequence environments. I’ve supervised dive crews of up to 12 divers, enforced strict safety protocols under OSHA 1910 Subpart T and ADCI standards, and maintained a spotless safety record while executing under pressure.

I lead with accountability and alignment. I plan the work, assess the risks, and ensure that every diver, every vessel, and every support system functions as part of a coordinated whole. Whether working alongside USACE or managing dive operations in remote and supply-limited regions, I deliver operational clarity and dependable execution.

My ability to integrate technical skill, regulatory precision, and real-world leadership sets me apart, building high-performance teams that know their role, trust the plan, and execute with precision. I am equally comfortable leading demo teams with prototype systems as I am coordinating response efforts in fast-moving emergencies.

Let's connect if you're looking for a commercial dive leader who brings discipline, adaptability, and field-tested leadership to your marine or infrastructure projects.
