When does KWS come in?
- Service or fault. A module that has been removed does not have to go straight to waste. We first assess whether repair, component repair or reuse is technically possible.
- Refit or dry dock. Several modules or packs come out in a short time. We collect the data in advance and set the work up as a project.
- Recurring returns. For integrators, yards and service organisations we agree a fixed way of working, so that not every consignment starts from scratch.
- Phase-out. If further use is not justified, the battery goes to suitable processing and we record consignment, weight, condition and outcome.
Step 1: pre-acceptance
Before anything is transported, we collect the data: manufacturer, system and model, serial numbers where available, chemistry, voltage and energy content, quantities, total weight, condition, state of charge, location and current packaging. Photos of the rating plate, connections and any damage are part of it.
Step 2: deciding what happens next
The intake leads to one of four outcomes: suitable for further technical assessment, additional packaging or inspection needed first, straight to suitable processing, or outside what we can accept at that point.
That way we do not commit to transport before it is clear what is being offered.
Step 3: project-based execution
For larger consignments, collection, batch registration and reporting are part of the agreement. We match transport and processing to type, condition, volume and the regulations that apply at the time.
We do not treat intact, defective and damaged batteries as one category.
What we do technically
- intake of packs, modules and battery components, visual and on paper;
- electrical diagnosis and fault assessment, when construction and safety allow;
- assessment of housing, connectors, interfaces and BMS and electronics;
- repair of suitable components, when that is safe and permitted for the application;
- batch registration of identity, weight, condition, treatment and outcome.
Experience with Corvus components
KWS has practical experience with battery components from Corvus and knows the technical context of maritime lithium systems. We use that experience in pre-acceptance and when assessing components.
Which work on a specific module is justified and permitted is decided per project. We do that together with the client, the manufacturer or integrator, and with the class requirements in mind.
Four ways of working together
- One-off project. A consignment after a refit, repair, incident or warehouse clear-out.
- Recurring returns. Periodic, with fixed agreements on intake and reporting.
- Behind the integrator. The integrator keeps the customer relationship, KWS does the agreed technical work.
- Preparing a phase-out. Quantities, planning, packaging and reporting are ready before the first battery leaves the vessel.

Frequently asked questions
KWS has experience with battery components from Corvus. Whether repair of a specific module is possible and permitted depends on the system, the condition, the parts, the conditions set by the manufacturer or integrator and any class requirements. That is why we assess every request in advance.
Yes, on a project basis. We set up the collection once type, condition, quantity, packaging, location and transport have been assessed.
At least manufacturer and model, quantities, energy content and voltage, condition, weight, location, packaging and clear photos of the rating plate and the battery.
No. Damaged, defective or thermally stressed lithium batteries can be subject to different safety and transport conditions. That is why we assess the condition in advance.
We agree that per project. This can include batch identification, quantity or weight, technical category, the chosen outcome and the accompanying transport or processing documents.
Do you have maritime batteries to deal with?
Send us the manufacturer, model, quantities, condition and location. We first assess what is suitable. You can also read about quality and safety, battery regulation and knowledge and advice.
