What we build
Every barge is built to order
Every unit we deliver is engineered to your project — excavator class, water depth, site conditions, transport format. If you have requirements, we build around them.
That said, 14 years of builds leave a useful trail. The configurations below are real designs from real projects. If your requirements are close to one of them, we use it as a starting point — less time to production, same level of engineering rigour.

Payment & financing
No-risk payment
Two options, both structured to keep you in control throughout the project. The payment schedule is confirmed during the quotation process — before any commitment is made.
Milestone-based payments
Payment is tied to defined fabrication stages — not collected upfront. At each milestone, you receive a progress report with photos from the production floor. You know exactly what has been completed before the next payment is due.
The factory is open for client visits at any stage of production.
Export financing available
Financing may be available through Estonia's state export support programme. The programme independently verifies production progress before releasing funds — milestone oversight at two levels, not one. Mention it in your enquiry if this is relevant to your project.
Delivery Designed to
Designed to
travel light.
Before we draw the first weld line, we know how the platform reaches your site. If your access road has a 3.5 m width limit, that determines how we section the hull. If your site is in another continent, we've probably shipped there before. Either way — it's our problem to solve, not yours.
Road — sectioned delivery
We cut the platform into sections that fit your country's road permit dimensions — width, height, axle load. This is decided at the design stage, not after fabrication. Most sections are bolted together on site in a day, with standard tools. If you want one of our engineers there for the first assembly, we come.
Works for Europe and export — same process, same drawings.
Container — worldwide export
For sites outside Europe, we dimension sections to fit standard shipping containers. We've delivered to Central America, the Middle East and Africa. The shipment arrives with numbered sections, assembly drawings and a direct contact for questions. For straightforward projects, your crew assembles it. For heavier or more complex builds, one of our engineers is on site by default — that's included.
Proven on multiple continents. Ask for references.
Monohull — sea/special transport
Larger single-hull platforms travel by sea or heavy-road transport. We review the routing, documentation and logistics as part of the project — not as an afterthought. You don't need to arrange this separately. We handle it.
Delivery method confirmed before production begins.

Say it upfront.
New-build doesn't mean starting from zero. If you have a fixed mobilisation date, tell us before the design is locked — not after. There are three things we look at.
How it works From enquiry
From enquiry
to handover.
No tender maze. One technical contact, a visible production sequence and payment stages tied to progress — not promises.
Send the project
details
Excavator class, target load capacity, water depth, site location, access road constraints and target delivery date. You describe the job. We do the technical translation.
Technical
review
We go through what the platform needs to do, where it operates and how it gets to site. Everything that shapes the build gets reviewed before any price goes on paper.
Price and
lead time
You receive a budget figure and production lead time. This gives you enough to make a decision — or to ask us to go deeper before you commit to anything.
Specification
freeze
Key dimensions, structural drawings, equipment interface points, production milestones, payment stages and delivery method are confirmed in writing. Fabrication begins only after sign-off on both sides.
Production and
delivery
Production milestones are reported with photos from the yard. Registration is handled on our side — Traficom or a classification society depending on your requirements. The platform arrives registered and ready to work. Warranty and after-sales support are part of the handover — not an afterthought.
Why Stalmar Here's exactly
Here's exactly
what to expect.
Six things that matter most when you're ordering a custom platform from a team you haven't worked with before.
Request pricing and lead timeThe dimensions, deck layout and load capacity come from your requirements: your excavator, your site, your access constraints. If something in the specification doesn't fit your project, it changes before production — not after you take delivery.
- built to your requirements
- 8–45+ m length
- 30–500+ t deck load
Every payment is released against a confirmed production milestone — not a schedule. Before each stage you receive a progress report with photos from the production floor. The factory is open for visits at any point. If export financing is relevant to your project, it adds a further layer of payment control tied to independently verified progress. Your money moves when results are visible — not before.
- milestone-based payments
- photo updates
- factory visits open
- export financing available
Production, documentation, registration — those are on us. Questions that come up mid-build get resolved on our side. You receive progress updates along the way and a ready platform at the end. Nothing lands on your desk that you weren't expecting.
- production
- documentation
- registration
- no surprises mid-project
Registration is handled before delivery: Traficom for inland European projects, or a recognised classification society where required. If on-site assembly support is needed, that's arranged. Warranty terms are confirmed at handover. After-sales contact stays with the team that built it — the people who know it. You receive a platform ready to work, not a starting point for more coordination.
- registration included
- warranty
- after-sales support
- assembly assistance
A platform engineered for road transport from the first drawing costs significantly less to move than one adapted after fabrication. The same logic applies when your project moves to a different site in two years. Transportability is a design decision — one that reduces your initial cost and your total cost of ownership over the platform's working life.
- transport-optimised from day one
- lower initial cost
- lower TCO
Wrong specification. Late delivery. Structural problems. These are the things you're thinking about — and the same engineering team and production yard have already worked through them across 100+ platforms delivered to dredging contractors in Europe, Central America, the Middle East and Africa.

FAQ
Common questions.
Our core expertise covers platform lengths from 8 to 45+ m, with deck load capacity from 30 to more than 500 tonnes. Because our solutions are modular, we also have experience assembling larger platforms beyond that range. What matters is what your project requires — working out how to build it is our engineers' job.
Material selection is based on load, operating conditions and project requirements. This may include standard structural steel, shipbuilding-grade steel, Hardox wear-resistant steel or other grades. We do not default to a single material across all builds.
Yes. We have experience across both — from shallow inland waterways to coastal and offshore environments with significant water depth and wave conditions. The hull form, structural design and equipment configuration are adapted specifically to your operating environment. Tell us your site conditions and we design around them.
Yes. Spud legs and drives are standard equipment for dredging configurations. We also supply hydraulic power packs, ramps, railings and deck reinforcement as part of the build.
Yes — and we'd be glad to have you. Our engineering team is based in Pori, Finland. The main production yard is in Kohtla-Järve, Estonia. Let us know you'd like to visit and we'll arrange everything.
We respond to every enquiry within 1 business day. If your requirements are clear from the outset, initial pricing will follow shortly after. If we need more detail first, we'll ask — and turn around a full quotation as quickly as possible from there.
It depends on what you need and current production capacity. There is no fixed number we can give honestly. Tell us what you need and when you need it — we'll tell you what's possible and look for options if the timeline is tight.
We have delivered platforms to contractors across Europe, Central America, the Middle East and Africa. In most cases we can advise on what to expect and help coordinate the process. Write to us with your location and we'll tell you what we know.
Warranty is always included. The exact scope and duration depend on the specific build and are confirmed in writing before handover. If you have particular requirements, raise them during the quotation stage.
Yes. After-sales support and assistance with questions following delivery are included. You retain direct contact with the same team that built your platform.
