What Maresco Ltd does
Maresco Ltd is a Greece-based specialized provider of products and services for the aquatic environment, founded in 1984 by Dr Lucas Caloumenos and restructured into a limited company in November 2010. The company operates from a single headquarters in Agios Dimitrios, Attiki, and combines a partner-led distribution business with in-house technical services and R&D. Its commercial activity centres on the regional (Greece and Cyprus) sales representation of marine and oceanographic equipment from international manufacturers — including sensors and profilers (CTDs, ADCPs, current meters, echo sounders), underwater robotics (ROVs, AUVs, USVs), imaging systems (multibeam sonars, cameras, hydrophones), and specialized underwater tooling — alongside the in-house design and manufacture of custom underwater housings, ROVs, USVs and bespoke instrumentation.
The company monetizes through hardware distribution and rental, professional services (technical support, assembly, repair, customization, remote assistance), and field survey services (vessel and underwater structure inspections, shipwreck retrieval, hydrographic surveys, photogrammetry). It also participates in European and national research projects — historically FP7, Horizon 2020 and NSRF, and more recently the European Defence Fund — most notably as a consortium member in PASITHEA (EDF 2022, 4 million euros over 36 months, developing Hybrid Autonomous Unmanned Vehicles combining UAV and UUV technologies), and as awardee of two EDF 2024 projects, PLEIADES and AQUILA. Its customer base spans the Hellenic Navy, the Hellenic Centre for Marine Research, multiple government ministries, water authorities, public energy companies, Greek universities, and private technical and fishing-sector firms. Recent strategic positioning includes SEKPY membership (May 2025) and a DEFEA 2025 exhibition presence, evidencing a deliberate move into the Hellenic and EU defence industrial base while retaining its research and industrial distribution core.

Maresco Ltd product offering
Product offeringCore offering
Maresco Ltd distributes marine and oceanographic scientific equipment (sensors, CTDs, ADCPs, current meters, hydrographic survey instruments, ROVs, AUVs, USVs, and underwater imaging systems) for aquatic environment applications across Greece and Cyprus via a partner network. The company also delivers technical services including marine and hydrographic surveys, vessel and underwater structure inspections, photogrammetry, salvage survey support, equipment customization, assembly, repair, and remote technical support. An in-house R&D department designs and manufactures custom underwater housings, ROVs, USVs, and specialized tooling, and participates in European and National research projects (FP7, Horizon 2020, EDF, NSRF).
Product overview
Maresco Ltd operates as a specialized provider of products and services for aquatic environments, functioning both as a distributor of marine scientific equipment and a provider of technical services. The product portfolio centers on Sensors & Multimeters Profilers (including CTDs, ADCPs, echo sounders, GPS receivers, current meters), ROVs/AUVs/USVs (underwater robotics for inspection and work), and Underwater Imaging Solutions (cameras, sonars, hydrophones). These distributed products are complemented by Technical Support Services (demonstration, repair, customization, remote support) and specialized Marine Survey Services (inspections, retrieval operations, hydrographic data collection). The R&D department supports Custom Instruments & Equipment manufacturing and conducts research projects (European Defence Fund, Horizon). The offering architecture is distribution-based with integrated service support, rather than a unified software platform.
