MarShip

What MarShip does

MarShip is a privately held UK-based company, founded in the mid-1990s by Director Peter Weide and headquartered in Tewkesbury, that specialises in diesel engine maintenance for marine, agricultural, and mining applications. The company's product portfolio centres on three engineered systems: Air (washable pleated turbocharger and panel filters recommended by MAN), Fuel (the patented Diesel Dipper tank separator, Diesel Duck portable cleaner, Diesel Drake automated dewatering unit, Marine Fuel Purifier, and the DieselAid additive range covering biocides, lubricity improvers, deposit control, cold flow improvers, and stabilisers), and Oil (the EDI Lube Oil Purifier, real-time and mobile oil monitoring, and spectrographic oil analysis). Core technology is mechanical separation and chemical treatment rather than digital, anchored by a 2020-granted patent on the Diesel Dipper Tank Separator Unit and a patent-pending equivalent in the Diesel Drake. EDI Lube Oil Purifier's heated-plate stage is positioned as the only oil purifier on the market that removes fuel dilution, and supports documented customer savings of up to 75% on oil spend.

MarShip makes money primarily through one-time product sales of hardware (MFP units from £297, EDI Lube Oil Purifier at quote-based enterprise pricing, washable filters, additive containers from 1 to 200 litres) and OEM engine parts for Caterpillar, Cummins, MAK, and Deutz engines (priced ~30% below main suppliers), supplemented by rental of portable EDI800 and Diesel Duck units and recurring consumables (DieselAid additives, replacement filters). The go-to-market combines direct e-commerce via the proprietary MarShip Marketplace and Amazon/eBay/PayPal for SMB and consumer buyers, exclusive or core distributors in Australia (Flow Marine), Ireland (TrueFlow), and DACH (ISY GmBH) for regional reach, and direct enterprise sales supported by industry exhibition presence at SkipperExpo and Seaworks International. Customer segments span commercial fishing fleets, work boats, pleasure yachts, merchant shipping, offshore vessels, agricultural machinery operators, and marinas, with named enterprise logos including SVITZER, P&O Nedlloyd, DFDS, Ocean Gas LPG, Arriva Buses, and Houchin. The company is bootstrapped with 1-10 employees, no external funding disclosed, and operates from a single UK headquarters with global shipping.

Broad incumbents

• Caterpillar Marine: Major manufacturer of marine diesel engines. MarShip serves as an alternative parts distributor and after-sales provider for Caterpillar marine engines at ~30% better pricing. Shares customer base but MarShip addresses aftermarket maintenance while Caterpillar focuses on engine manufacturing and warranty service.
• Stanadyne: Manufacturer of fuel injection systems and filtration products for diesel engines. Competes with MarShip in fuel treatment, particularly addressing Internal Diesel Injector Deposits (IDID) in common rail systems where MarShip positions its lubricity and deposit control additives.
• Castrol Marine: Major marine lubricant brand owned by BP. Competes indirectly with MarShip's EDI oil purification and DieselAid additive ranges by offering alternative approaches to oil life extension, with much larger scale, broader distribution, and direct engine manufacturer partnerships globally.
• Shell Marine: Shell's marine lubricants and fuel additive business serves the same global marine customer base. Global scale player in marine fuel treatments with substantially broader product portfolio, port-based distribution network, and OEM relationships than MarShip's niche specialty offerings.
• Wärtsilä: Major marine engine manufacturer and lifecycle service provider. Director Peter Weide was formerly Head of service sales at Wärtsilä. Serves the same marine customers with much broader engine manufacturing and service portfolio, but does not focus on aftermarket fuel/oil purification systems like MarShip.
• Cummins Marine: Major manufacturer of marine diesel engines. MarShip distributes genuine Cummins marine parts at better pricing than main suppliers. Shares customer base with MarShip providing complementary aftermarket parts and engine maintenance products rather than competing directly.

Direct peers

• Donaldson: Global filtration manufacturer serving diesel engine applications across marine, agricultural, and mining sectors. Competes with MarShip in air and liquid filtration with broader industrial focus, larger scale, and established OEM relationships with major engine manufacturers.
• Alfa Laval: Global leader in marine separation equipment including fuel oil separators and lube oil purifiers. Directly competes with MarShip's EDI and fuel purification products in marine applications, but operates at much larger scale with broader marine portfolio including heat exchangers, boiler systems, and full ship solutions.
• Separ: European manufacturer of fuel filters and water separators specifically designed for diesel engine applications. Direct competitor in fuel/water separation for marine and industrial diesel, focused on similar product category as MarShip's fuel purification systems.
• Parker Hannifin (Racor): Major manufacturer of marine fuel filtration and water separation systems including the Racor turbine series for marine diesel engines. Direct competitor with MarShip's Diesel Dipper and Diesel Duck product lines in marine fuel polishing and water separation, with broader industrial filtration portfolio.
