Marine & Industrial Solutions

What Marine & Industrial Solutions does

Marine & Industrial Solutions, operating under the legal entity Princeps Invest OÜ (also branded Princeps Solutions), is a privately held Estonian marine and industrial solutions provider founded in 2007 and headquartered at Vanapargi 2, Pärnu. The company functions primarily as an official regional distributor for six international brands across Estonia, Latvia, and Lithuania: SEMA Gases (calibration gases and regulators), GMS Instruments (pressure, temperature, flow, level, and diagnostic measurement), Industrial Scientific (gas detection hardware and connected-safety software), Searchmaster (intelligent LED searchlights for vessels), modec (portable valve actuators with modec connect data platform), and alkitronic (electric, pneumatic, hydraulic, and manual torque multipliers with ±3% repeatable accuracy). Its customer base targets vessel operators, shipping companies, shipyards, and adjacent marine and industrial segments including offshore, energy, and manufacturing.

The business model combines three revenue streams: (1) hardware product distribution from stock, with quote-based pricing and 24-hour average delivery on certain lines; (2) equipment rental, principally gas detectors on flexible short-term terms with same-day delivery and factory-trained calibration; and (3) logistics services spanning multimodal freight (sea, rail, truck, airfreight), customs clearance, cold storage, hazardous and project cargo handling, and value-added services such as labeling, repacking, and shrink wrapping. Pricing is uniformly quote-based with no public list rates, and customer engagement is direct via email, phone, and downloadable product catalogs.

The company is bootstrapped, with no external funding, no parent organization, and no disclosed subsidiaries. It is a member of Maritime Cluster Estonia and markets through its website (princepssolutions.eu) and a LinkedIn company page. As of the most recent product-page updates in 2024–2025, the company remains operationally active and is extending its service mix through the gas detector rental offering and its Latvia/Lithuania distribution footprint.

• Kongsberg Maritime: Marine technology supplier of navigation, sensors, automation, and integrated systems for vessels. Comparable to Marine & Industrial Solutions' distribution of maritime sensors and Searchmaster searchlights, although Kongsberg is principally a manufacturer.
• GAC (Gulf Agency Company): Global ship agency and logistics company providing vessel husbandry, supply, spares coordination, and freight forwarding. Overlapping with both the maritime services and logistics services offered by Marine & Industrial Solutions.
• Drew Marine: Global marine chemicals, equipment, and supplies distributor serving vessel operators. Closely comparable product mix (consumables, spare parts, technical supplies) and customer base to Marine & Industrial Solutions' distribution business.
• Wilhelmsen: Global maritime product distribution and ship service company that supplies safety equipment, instruments, and marine consumables to vessels worldwide. Directly comparable business model to Marine & Industrial Solutions' distribution-plus-services motion, only at vastly larger scale.

Regional players
