# Marine Debris Collection: Port Work for Suppliers > Marine debris collection is port-call work: fouled propellers, blocked intakes and waste handling. What chandlers, agents and repair yards can sell, and how to win it. URL: https://vesselreach.si/blog/marine-debris-collection-port-work-for-suppliers | Published: 2026-11-05 | Updated: 2026-11-07 | Industry news | Topic: Carrier service and surcharge changes ## In short Marine debris collection is a port-call service that ship chandlers, port agents and repair yards can sell before a vessel arrives. Floating debris fouls propellers, blocks cooling water intakes and damages hulls, so operators need inspection, cleaning and waste disposal. Suppliers can bundle debris removal, hull cleaning and MARPOL documentation, and use vessel arrival data to reach the right buyers early. ## Key takeaways - Debris in ports can foul propellers, block cooling water intakes and damage hulls, creating repair bills and off-hire time. - A 2021 IEEE Access study paired a UAV with a UUV to find and collect floating debris in ports where large vessels cannot enter. - A 2023 IEEE Transactions study used Sentinel-2 satellite data to separate plastic debris from other floating material with 98% accuracy. - Ship chandlers, port agents and repair yards can quote debris collection, disposal and MARPOL documentation before the ship berths. - VesselReach identifies the company behind each vessel and its operations, procurement and technical superintendents before arrival. ## At a glance - **What: What did the Brazilian builder make?** A boat built from 230 discarded plastic containers to collect rubbish from the sea, using 125 two-litre plastic bottles and 105 five-litre disinfectant containers. ([Splash247](https://splash247.com/brazilian-builds-boat-from-rubbish-to-collect-more-rubbish/)) - **Who: Who built it?** Marcos Arnhold, a former Brazilian ocean canoeing champion, who spent two months building the craft. ([Splash247](https://splash247.com/brazilian-builds-boat-from-rubbish-to-collect-more-rubbish/)) - **How: How can floating debris be collected in ports?** A 2021 IEEE Access study proposed a UAV and UUV working jointly to locate and collect floating debris in complex topographies such as ports, where large vessels cannot enter. ([IEEE Access](https://doi.org/10.1109/access.2021.3076110)) ## What is marine debris collection as a port-call service? Marine debris collection is a port-call service: removing floating rubbish, plastics and waste from harbour waters and vessel spaces, then handling disposal and compliance paperwork. It sits alongside hull cleaning and waste reception in the work a ship needs while alongside. The demand is real enough that a former Brazilian ocean canoeing champion built his own boat to do it. According to [Splash247](https://splash247.com/brazilian-builds-boat-from-rubbish-to-collect-more-rubbish/) (November 2026), Marcos Arnhold spent two months building a craft in Guaratuba, southern Brazil, from 230 discarded plastic containers, including 125 two-litre plastic bottles and 105 five-litre disinfectant containers. A one-boat local initiative is not a market. The reason it matters to suppliers is that it points at a service gap that ports, [port agents](https://vesselreach.si/solutions/port-agents) and [ship chandlers](https://vesselreach.si/solutions/ship-chandlers) are better placed to fill commercially. ## Why does debris matter for port call work? Debris in port waters creates concrete costs for the vessel and the operator: fouled propellers, blocked cooling water intakes and hull damage, all of which mean repair bills and off-hire (time when a chartered ship is unavailable and the owner stops earning hire). A 2026 study in Iconic Research and Engineering Journals surveyed 320 maritime professionals on the Calabar, Onne-Bonny, Port Harcourt and Warri waterways in Nigeria. It found that plastic debris, wrecked vessels and ghost fishing gears each had significant effects on navigational hazards, safety risks and economic outcomes in those port channels ([Iconic Research and Engineering Journals](https://doi.org/10.64388/irev9i7-1713457), January 2026). For a service provider, that translates into four sellable jobs: - Underwater inspection and propeller cleaning before debris causes damage. - Waste reception and disposal arranged around the ETA (the estimated time of arrival the agent works to). - Hull cleaning that also removes attached growth and trapped debris. - Documentation to support compliance at port state control (the inspection of foreign ships by the port authority for safety and pollution standards). ## What technology is changing the work? Detection and collection tools are moving from pilot projects into something a service company could operate on contract. A 2021 study in IEEE Access proposed a system using a UAV and a UUV (an unmanned aerial vehicle and an unmanned underwater vehicle) working together to locate and collect floating marine debris in complex topographies such as ports, where large vessels cannot enter ([IEEE Access](https://doi.org/10.1109/access.2021.3076110), 2021). A 2023 study in IEEE Transactions on Geoscience and Remote Sensing used Sentinel-2 satellite data to detect and distinguish plastic debris from other floating materials, reporting 98% accuracy for suspect plastic debris ([IEEE Transactions on Geoscience and Remote Sensing](https://doi.org/10.1109/tgrs.2023.3283607), 2023). The service model already exists in research form. The RoboVaaS project set out an on-demand, cloud-based system that dispatches unmanned vehicles to support ships and port activities, including environmental data collection and hull inspection ([IEEE Journal of Oceanic Engineering](https://doi.org/10.1109/joe.2023.3234710), 2023). A yard or marine service company that can run drones or underwater vehicles on a call-off basis is selling exactly that, before a port authority builds it in-house. ## What does the science say about marine plastics? Plastics in the ocean are quickly colonised by microbes, forming a community known as the Plastisphere. A 2020 review in Environmental Science & Technology discusses how this biofilm drives interactions between plastics and the marine environment, including the potential for pathogenic hitchhikers ([Environmental Science & Technology](https://doi.org/10.1021/acs.est.0c02305), 2020). That matters commercially because waste handling and hull cleaning stop being only about appearance. They become part of preventing the spread of invasive species and meeting environmental obligations, which is a conversation a [ship repair yard](https://vesselreach.si/solutions/ship-repair-yards) can have with a technical superintendent during a dry-docking quote. ## How should maritime service providers respond? [Ship chandlers](https://vesselreach.si/blog/alfa-laval-buys-navtor-what-it-means-for-suppliers), bunker suppliers, [port agents](https://vesselreach.si/blog/drone-carrier-tests-port-work-behind-naval-visits) and repair yards can turn environmental pressure into new revenue by packaging debris and compliance work into the services they already quote. 1. **Add debris collection and disposal to your service catalogue.** Offer port authorities and vessel operators a single point of contact for waste removal, including plastics and hazardous materials. 2. **Partner with technology providers.** Drones and underwater vehicles can inspect hulls and collect debris in hard-to-reach areas. Position yourself as the integrator that holds the contract. 3. **Promote environmental compliance.** Help vessels meet MARPOL (the IMO convention covering pollution prevention from ships) and port state control requirements with documentation and [waste reception facilities](https://vesselreach.si/blog/port-state-control-detention-work-for-port-suppliers). 4. **Target vessels with upcoming port calls.** Use vessel arrival data to find ships that may need hull cleaning or waste services before they arrive, which is the same discipline described in [how a port call is staged and who buys what](https://vesselreach.si/blog/port-calls-meaning-stages-parties-and-supplier-work). [Port agents](https://vesselreach.si/blog/shore-power-sales-work-for-port-suppliers) can coordinate debris removal with the port authority and fold it into the PDA (the port disbursement account, the estimate of costs an agent sends the owner before the call). Repair yards can bundle hull cleaning and inspection into a dry-docking package, as covered in [robotic hull inspections and what yards can sell](https://vesselreach.si/blog/robotic-hull-inspections-work-for-ship-repair-yards). Chandlers can add eco-friendly products and waste management to differentiate a commodity catalogue. ## How VesselReach helps Debris work is only won if you reach the right person before the ship sails. VesselReach turns vessel movements at your target ports into conversations with the decision-makers who buy port services. - **Vessel intelligence:** vessels near your ports plus scheduled and expected arrivals, so you can pitch debris collection or hull cleaning before the ETA, which means the quote lands while the superintendent is still planning the call. - **AI company targeting and decision-maker discovery:** the AI identifies the company behind each vessel and finds operations, procurement and technical superintendents, which means fewer hours spent matching ships to buyers by hand. - **Multichannel outreach with AI enquiry handling:** staged email, WhatsApp and phone contact, with routine questions answered from approved information and human handoff on the mobile app. Pricing is per customer and quoted after a demo; a 10-day free trial follows the meeting. Request a VesselReach quote or book a demo to see how it works on your ports. ## Frequently asked questions ### What is marine debris collection in a port call? It is the removal of floating rubbish, plastics and waste from harbour waters and vessel spaces during a call, plus disposal and the compliance paperwork. Suppliers bundle it with hull cleaning, waste reception and inspection work. ### Does marine debris really affect navigation in ports? A 2026 survey of 320 maritime professionals across four Nigerian port channels found plastic debris, wrecked vessels and ghost fishing gears each had significant effects on navigational hazards, safety risks and economic outcomes. ([Source](https://doi.org/10.64388/irev9i7-1713457)) ### Can satellite data find floating plastic debris? A 2023 study in IEEE Transactions on Geoscience and Remote Sensing used Sentinel-2 imagery to detect and distinguish plastic debris from other floating materials, reporting 98% accuracy for suspect plastic debris. ([IEEE Transactions on Geoscience and Remote Sensing](https://doi.org/10.1109/tgrs.2023.3283607)) ### How can a ship chandler sell debris collection work? Add waste collection and disposal to the service catalogue, partner with drone or underwater vehicle operators, and contact technical superintendents and procurement before the vessel arrives rather than after it berths. ### Why does the Plastisphere matter for hull cleaning? A 2020 review in Environmental Science & Technology describes how plastics are colonised by microbes forming a biofilm, with potential for pathogenic hitchhikers. That strengthens the case for proper waste handling and hull cleaning. ([Environmental Science & Technology (American Chemical Society)](https://doi.org/10.1021/acs.est.0c02305)) ## Sources 1.

A Brazilian built a boat from plastic containers to collect rubbish, highlighting the problem. Research shows drones and satellites can help detect and collect debris. For ship chandlers, agents and repair yards, offering debris removal and compliance services can win work from vessels before arrival. Use vessel data to target ships needing hull cleaning or waste services. Marine debris removal is a port service, not just an environmental cause. Floating plastic fouls propellers, blocks cooling intakes and damages hulls, so vessels arriving at your port need inspection, cleaning and waste disposal. That is work a ship chandler, port agent or repair yard can quote before the ship berths. Detection tools are improving: a 2021 IEEE Access study paired a UAV with a UUV to find and collect debris in ports where large vessels cannot enter, and a 2023 IEEE Transactions study used Sentinel-2 data to separate plastic from other floating material. Both point to monitoring and collection niches for marine service companies. Marine debris definition questions aside, the commercial point is simple: offer collection, disposal and MARPOL documentation as one package, and reach the vessel before its ETA. What is marine debris collection worth to a port agent? It is a bookable service: removal of floating waste and hull cleaning, with disposal and documentation, sold to vessels and port authorities before arrival. What do ship chandlers do with waste work? They bundle debris removal with eco-friendly products and MARPOL paperwork as one offer. Which vessels need it first? Those with upcoming port calls, reached through vessel arrival data. VesselReach finds the company behind each vessel and the buyers of port services, so the offer lands before the ship berths.
