Marine & industrial electrical engineering
Keeping critical electrical and automation systems running
When a VFD, a PLC or an integrated power system fails, downtime gets expensive fast. I diagnose, repair and commission the systems your vessel, rig or plant depends on. On site, anywhere in the world.

Why operators call me
Built for the systems you cannot have offline
-
Complex installations
Propulsion drives, top drive VFDs, integrated PMS and EMS. When these stop, the whole operation stops. That is where I am most useful.
-
A direct line to the engineer
No chain of people. From the first call to the final test you deal with me. Short response times, one person accountable.
-
Field-tested, worldwide
25 years and more than 50 countries. Shipyards, rigs, production fields and industrial sites on six continents. Most failure modes I have seen before.
Services
Where I add the most value
These six areas are my daily work. If your problem sits between disciplines, or nobody can say where the fault actually lives, that is usually where I am needed. The boundaries between drive, control and power are where the real problems hide.
01
PLC programming & automation
Siemens Step7 and TIA Portal, Allen Bradley, WAGO, Praxis. Troubleshooting legacy logic, rewriting code blocks, commissioning new platforms.

Commissioning & servicing
Electrical, mechanical and hydraulic commissioning of new installations and revamps. ATEX commissioning, structured handovers, documented test protocols.
Read more04
EMS & PMS integration
Propulsion, energy management and process control, integrated over Modbus, Profibus, NMEA, J1939 and Ethernet, so the bridge sees what the engine room is doing.

VFD houses & top drive systems
Tesco, Varco, ABB and Canrig top drives and the VFD houses that feed them. Rig moves, re-commissioning, panel rewires after fires.

Battery-powered & hybrid vessels
Charging systems, energy management and propulsion control on battery-electric and hybrid ferries, water buses and crew transfer platforms.

Approach
A specialist, not a generalist
My work sits where electrical power meets control systems. On a complex installation that is where most faults start. Over the past 25 years I have commissioned, serviced and rescued systems for drilling contractors, shipbuilders, vessel owners, EPCs and operators in more than 50 countries.
New-build battery-electric ferries, top drive rescues on land rigs, revamps on producing platforms: at the core the work is the same. Understand the system, get it stable, get it back to production.
Since 2020 I have worked freelance under jvissers.com, from a fully equipped 120 m² workshop in the Netherlands. I travel to client sites worldwide on short notice. Direct for owners and operators, or through EPCs, system integrators and yard project teams.

Understand the system. Get it stable. Get it back to production.
The job is the same on every site
In the field
Work from the field, without the names
Client and vessel names stay confidential. The work itself I can show: what the installation was, what was wrong or what was needed, and what I did about it.
Utility · Grid support
Grid support generator
Peak shaving, standby power and seamless synchronisation during critical operations. Both frequency and voltage are controlled, keeping reactive power (kVAr) to a minimum.

Marine · Battery vessels
Battery system troubleshooting
Battery systems keep getting bigger, and so do the control systems behind them: complex, and sensitive to faults. The devil is in the details.

Marine · Power drives
New bow thruster drive
One of the vessel's two bow thruster drives had failed. I installed a new drive and improved the response of both by moving from speed limiting to torque control.

Inspections
Maintenance is more than changing a filter. A good inspection tells you what is about to fail before it breaks down.

Marine · Grid converters
50 to 60 Hz grid converter
50 Hz is used in most parts of the world, but not everywhere. This grid converter reliably supplies 10 kW at 208/120 V, 60 Hz, with a minimal footprint and minimal losses.

10-year refit: new VFDs
Six government fleet vessels received their 10-year refit. I replaced and programmed all drives on each vessel and optimised the drive settings to improve the behaviour…

System down?
Call. The phone is faster than the form.
+31 6 838 507 23I answer personally and can be on site at short notice.
Have this at hand when you call
- Make and model of the system: drive, PLC, top drive, PMS
- Where the vessel or rig is now, and where it will be
- What happened, and when it has to run again
- Who I can reach on site
Discretion, built in
A meaningful share of my work involves proprietary control systems, prototype installations or operationally sensitive data. I treat confidentiality the way I treat safety: non-negotiable. NDA by default.
Talk to me about your project
A system down, a commissioning window coming up, or a specialist on call for the longer term. I respond personally, usually within one working day.
