At Röhlok we understand that traditional energy still has a part to play in maintaining not only our quality of life, but also powering our ever-accelerating transition to renewables. In the subsea energy sector, our aim is to make deep-water projects more reliable, less wasteful and more cost-effective.
Over an eight year career operating ROVs with DOF Subsea, TechnipFMC and Helix Energy Solutions (Canyon), our founder Tristan Janle realised there must be a better solution to the existing unreliability of ROV and associated equipment connectivity.
He has spent the last 6 years designing, testing and now manufacturing the unique Röhlok cabling system currently in service with two of the world's top ROV contractors.
Tristan was also recently the winner of RMIT University's LaunchHub#14 program for outstanding startup companies focussed on addressing UN Sustainable Development Goals.
At Röhlok, our mission is to revolutionise deep-water subsea equipment connectivity. Our patented innovative oil-filled cable system empowers industries operating offshore with unmatched reliability, ease of use and sustainability; delivering electrical connection solutions that enhance operational efficiency and minimise downtime

Oil-filled cables have several advantages over moulded rubber or plastic cables. Some of the advantages are:
• Oil-filled cables are significantly more reliable than other subsea cable types
• Oil-filled cables are easily field repairable and modifiable
• Oil-filled cables are significantly more cost effective than other subsea cable types
The patented Röhlok modular cable system is an new approach to electrical cabling. The innovative design is both durable and slim-line. This makes handling and routing as easy as a moulded rubber cable while still offering a straightforward and reliable method for in-field repair and reconfiguration.
Traditionally, yes. However, the Röhlok modular cable system overcomes all of the fiddly and messy parts. Every aspect of the assembly and filling process has been carefully designed to be clean and efficient leading to reduced downtime, less waste, and higher technician satisfaction.
Röhlok uses custom extruded German tubing that, unlike another well-known brand commonly used offshore, does not contain plasticisers. This means our tubing remains flexible even when exposed to UV light and hydrocarbons.
The Röhlok modular cable system is more cost effective than any other subsea cable system for a few key reasons:
Firstly, because it is more reliable than other cable systems. Independent testing commissioned by a number of ROV companies has confirmed that oil-filled cables have an expected life at least three times that of a moulded rubber unit. There are two main reasons why:
• The conductors are free to move within the outer sheath which means less stress and chance of an open circuit.
• There is no moulding to delaminate around the cable sheath, removing the potential for water ingress and short circuiting between conductors.
Secondly, the Röhlok modular cable system is unique in that it is truly modular. In the unlikely situation that any part is damaged that part alone can easily be replaced, vastly reducing the stock required and directly reducing your maintenance expenditure.
Finally, because our cables are reconfigurable. If you need a specific cable for an obscure piece of rental equipment that turned up with the incorrect plug for your ROV, you no longer need to pay the high costs associated with having a custom unit moulded at short notice, just reconfigure one - easy!
