Marine equipment sales look like a product sale and behave like a platform sale. Get that wrong and you spend two years quoting shipyards who were never going to buy from you.
I have sold cooling and equipment into Wärtsilä, Yanmar, MHI and Hamilton Jet, and I built the marine channel at Brannan that took the business from £1.8M to £6.2M. The pattern repeats. You win once at the engine builder or the yard, and you get paid for the next fifteen years. Or you win once, hand the parts revenue to somebody else, and wonder why all that volume never turned into profit.
The owner orders the vessel. The yard builds it. The naval architect, the systems integrator or the engine builder decides what goes inside it. Three organisations, three clocks, and only one of them has any interest in your product.
Most manufacturers new to marine aim at the owner because the owner has the money. He also has no interest whatsoever in your pump, your cooler or your control panel. He bought a vessel to a specification agreed with the yard, and inside that specification your component is a line somebody else owns.
The target is the engineering team. Wärtsilä, Yanmar, MHI, Hamilton Jet, the propulsion integrators, the larger yards. Engineering, not procurement. Procurement arrives once the design is settled, and by then the decision has narrowed to price against a part that is already drawn in.
Being drawn in is the biggest lever you have in marine and it tilts the odds hard. It is not the only route. Plenty gets won from the approved list on availability, lead time, service coverage and a sharp commercial case, particularly on refit and repowering. But if you are deciding where to spend the next twelve months, spend it with the engineers.
Every serious marine component carries type approval from a classification society. DNV, Lloyd's Register, ABS, Bureau Veritas, RINA, ClassNK. Depending on the vessel and its flag you may also need EU Marine Equipment Directive marking, the UK equivalent, or acceptance for US flagged vessels.
Type approval is not paperwork you complete after the order lands. It is a testing programme against class rules plus an audit of your manufacturing and quality system, and the societies themselves put it at three to six months minimum for a straightforward product. Complex equipment takes longer.
Which society matters as much as having one. Buyers specify different societies depending on flag, insurer and where the vessel trades. Hold DNV, walk into a yard working to ABS, and you are back at the beginning of a process you thought you had finished.
Type approval wins you nothing. Not holding it loses you everything before the conversation even starts.
Budget it, start it before a customer asks for it, and treat the class engagement as part of the sale. The manufacturers who get designed in turn up to the engineering meeting already approved for the society that OEM works to.
Here is what nobody tells a manufacturer entering marine. You get designed in. The OEM issues a part number. Your component sits in their catalogue under their number, at the price you agreed for series build. Ten years later that vessel needs the part replaced, the owner rings the OEM, and the OEM sells your component at a multiple of what they pay you.
You built the installed base. Somebody else monetises it.
That outcome is decided at the design in stage, in the supply agreement, not afterwards. The questions worth fighting over are simple enough. Does your part carry your identity in the service documentation. Can you supply the aftermarket directly or through your own channel. What happens to spares pricing across the life of the platform. Who owns the service network in each region.
None of it is easy to change once the platform is in production. Not every manufacturer wins that argument and some OEMs will not move an inch. Fine. But know which fight you are in before you sign, because it decides whether marine ends up a volume business or a margin business for you.
Marine spares get bought under pressure, in a port, at short notice, by somebody whose vessel is not earning. Availability beats price and it is not close.
That is a channel problem, not a pricing problem. Stock in the right places, partners who can service the product rather than just resell it, coverage in the ports where your installed base actually sits. Building that at Brannan is what turned a flat product line into growth. Not a better product. A better route.
Choosing those partners on instinct is where it usually goes wrong. Appoint the wrong service partner in a region and it costs you two years plus the reputation of the product, because a failed part with no support behind it becomes an owner who specifies against you next time. That is the problem Parteloa was built for, scoring partners against what you actually need before you appoint them rather than after.
Regulation forces redesign, and redesign is when a locked platform opens up. It is the most reliable way into an OEM that has used the same supplier for a decade.
The IMO Net Zero Framework is the one to watch. It was approved at MEPC in April 2025, adoption was postponed by a year to October 2026, and on the tacit acceptance procedure it would not enter into force until around 2028. So it is not law yet, and anyone telling you it is has not read it. But engine builders and integrators are already working through what compliance looks like, and that engineering work is happening now.
That is your window. Not the day the rule bites. The two or three years before it, when the design is genuinely being reconsidered and a supplier who understands the regulatory pressure gets a hearing that a cheaper supplier never gets.
If your marine business has flattened, it is almost never the product. It is that you are selling to the wrong organisation, or you were designed in on terms that gave the aftermarket away, or your channel cannot service what you have already sold.
