Cetasol sits firmly in the “make the ships you already own smarter” camp. Their iHelm platform bolts onto existing vessels, pulls data from engines, navigation and weather, then feeds captains and shore teams real-time advice on speed and power use, with case studies showing double-digit fuel savings on ferries and workboats while keeping schedule and comfort intact.

Cetasol Benefits:
- Turning data into fuel cuts: iHelm connects to engines, navigation and weather, then recommends speed and power settings in real time. Cetasol case studies report fuel reductions in the 10–20% range on ferries and coastal vessels once crews adopt the guidance in daily operations.
- Stabilising performance across captains and trips: The platform uses a digital twin of each vessel and route to shrink the spread between “best” and “average” operation, so high performers become the benchmark instead of the exception. That can be worth several percentage points of fuel on repeat services.
- Automating reporting and compliance work: iHelm captures and structures operational data so MRV, DCS and internal emissions reporting can be generated from the same dataset instead of manual logbook processing, saving staff time and reducing the risk of errors.
- Flagging maintenance issues earlier: Continuous engine and fuel monitoring means abnormal consumption or behaviour can trigger early warnings. That helps avoid running equipment in a damaged or sub-optimal state for months before the next yard stop.
- Scaling from one vessel to a full segment: Cetasol positions iHelm for small and mid-sized vessels like ferries, tugs, pilot boats and offshore craft, but the same platform scales across dozens of hulls, so lessons from one vessel can be rolled out across the fleet.
- Supporting hybrid and alternative driveline choices: Because iHelm is built to work with conventional diesel, electric and hybrid configurations, owners do not have to re-platform their optimisation layer every time they change propulsion technology.
- Anchoring decisions in an external reference: For more detail and current feature list, owners can go directly to Cetasol’s own materials. iHelm platform overview .
Notes: Savings figures are taken from Cetasol case material and third-party coverage and are indicative only.
Actual results depend on routes, weather, crew engagement and how aggressively you act on the recommendations.

iHelm fuel and ROI sketch
A simple way to frame what Cetasol-style optimisation might mean for your fuel bill and payback.
Your starting point
Use recent bunker spend for a typical vessel on the routes where you would deploy iHelm.
Plug in your own scenario. Many owners explore a range (e.g. 5–15%) in their internal cases.
Sister ships or route families where you would roll out the same playbook.
Include subscription, connectivity and an allowance for hardware and installation spread over time.
If you want, treat this as the capex lump sum (hardware, integration, training) you need to earn back.
Planning tool only. Swap in your own numbers from bunker reports, vendor quotes and internal cost models.

Cetasol’s value proposition is straightforward: instead of waiting for a newbuild or a big retrofit to change the fuel curve, you use iHelm to make today’s vessels behave more like your best days on your best routes. The mentions panel points readers to where iHelm is being discussed, and the savings sketch lets an owner plug in their own bunker and cost numbers to see whether a multi-vessel rollout is worth a deeper look with the operations and bridge teams that would actually use it.
