Jumbo Brand Guidelines: A 1948 Rotterdam Shipowner, the Stellanova & the K3000 Class

A Rotterdam shipowner that looked beyond the box.

Jumbo is a Dutch heavy-lift shipping and offshore transport and installation company. Dutch Wikipedia describes Jumbo Shipping as a trade name of Kahn Scheepvaart B.V., a family business founded in Rotterdam in 1948 by Hans Kahn, and says the fleet has had Rotterdam as its home port from the start, with the head office in Schiedam. The present website, under the name Jumbo Maritime, dates the heavy-lift business to 1968.

The company tells its origin as an idea. In the late 1950s, its history page says, when the container and the pallet were the big innovations in ocean freight, its founder developed a concept for the pieces that fitted into neither; until then heavy cargo had been carried with whatever equipment was available. Dutch Wikipedia sums up his motto as “not everything fits in a box.”

The first step was a small ship. Dutch Wikipedia says the first Stellaprima, delivered in 1956 by Abeking & Rasmussen at Lemwerder, was a coaster with four 12-tonne derricks, heavy for the time, so that objects which had travelled as deck cargo on ordinary coasters could go on a better-equipped ship. In 1967 the company ordered its first purpose-built heavy-lift ship, and in 1968 the Zaanlandse Scheepsbouw Maatschappij at Zaandam delivered the Stellanova, the first of Jumbo’s A-class. The company’s own history page ties the Stellaprima and the year 1968 together as the start of its life as a heavy-lift specialist.

A new class every few years.

Jumbo’s history is told through ship classes, each named by a letter. According to Dutch Wikipedia, two A-class sister ships, Daniella and Fairlift, followed in 1969; the B-class of 1974, built by Van Diepen at Waterhuizen, could lift 600 tonnes; the C-class arrived in 1977 and 1978; and the D-class of 1983, Jumbo Challenger and Fairmast, drawn by the company’s own designers, reached 1,000 tonnes. The G-class followed in 1994 and 1995, and the H-class, with two 400-tonne cranes per ship, in 2000. Around 1994, Dutch Wikipedia says, the company also bought a seagoing pontoon, the Jumbo Barge JB-1, because not every cargo was suited to being carried high on deck.

The J-class came between 2004 and 2008: Fairpartner and Jumbo Javelin, then Fairplayer and Jumbo Jubilee, with up to 1,800 tonnes per ship. The K-class, Jumbo Kinetic of 2014 and Fairmaster of 2015, was built in Split, Croatia, with two Huisman cranes of 1,500 tonnes each, Dutch Wikipedia says. By its count, the lifting capacity per ship grew from 100 to 1,800 tonnes in 38 years. The encyclopaedia adds a smaller detail: ship names were traditionally chosen in competitions among the staff.

The class names now work as specifications. On the company website the fleet is listed as Jumbo Kinetic and Fairmaster (K3000), Fairpartner and Jumbo Jubilee (J1800), and Fairlane and Jumbo Vision (H800), within the range of 800 to 3,000 tonnes that the company gives for its in-house designed ships. Two J-class ships, Fairplayer and Jumbo Javelin, have DP2 dynamic positioning, which Jumbo says lets them combine transport with offshore installation work.

How heavy-lift carriers present themselves.

Heavy-lift and project-cargo carriers sell something that is hard to show before it happens: the movement of a single object too large or too heavy for a container. Their websites lean on photographs of their own ships and cargo instead, heavy-lift vessels with paired cranes, decks loaded with modules, port cranes or offshore structures, published by the companies themselves as records of past voyages.

Colour carries much of the identity. Company names are painted large on hulls and crane booms, and across this sector the wordmarks often appear in strong orange, blue or red against white superstructures and dark hulls, so that they read from a quayside or in an aerial photograph. The same few colours then tend to run through the livery, the website and the printed material.

Fleet pages sit at the centre of these sites. Ships are grouped by class and described by crane capacity, deck area and deadweight: Jumbo lists its vessels as K3000, J1800 and H800 classes, and BigLift divides its fleet into heavy-lift types and heavy transport vessels such as the MC-Class. Engineering and transport services, from stowage planning to ship-motion analysis, are presented beside the fleet as a second product.

The rest of a typical site is evidence and reach: project-reference galleries sorted by market, from mining to offshore energy and port development; customer magazines and news of ships on order; and office maps showing sales and agency networks across several continents. This guide sets out what can be checked about each company, its founding, its ownership and its fleet, and marks clearly what rests on the company’s own word.

Offshore work and an alliance with SAL.

From 2003, the company says, Jumbo built on its heavy-lift ships to enter offshore and subsea installation, and it now presents itself as two businesses, shipping and offshore. Its shipping pages are organised by market, among them oil and gas, LNG, cranes and rolling stock, while the offshore side covers offshore, subsea and renewables work. The company says it started a Jumbo Innovation Program in 2011, run by a dedicated research and development team, and that its engineers carry out ship-motion and structural analyses when planning transports.

Commercially, Jumbo no longer sells its heavy-lift shipping on its own. In 2021 it formed a commercial alliance with the German carrier SAL Heavy Lift. Hellenic Shipping News reported in February 2024 that the Jumbo-SAL-Alliance would be replaced from 1 March 2024 by the JSI Alliance, which added SAL’s American sister company Intermarine, as a single marketing platform and brand for a combined fleet of about 50 vessels and a network of offices and agents in 23 countries. As owners and operators, the report said, Jumbo, SAL and Intermarine remained independent.

The fleet is growing again. In May 2026 Jumbo announced a contract with Dajin Heavy Industry for two L-Class vessels of 25,000 deadweight tonnes, developed in-house, each with two Huisman 1,200-tonne cranes, Hellenic Shipping News reported, publishing the company’s statement. The first is due in 2028 and the second in 2029, and both are to join the JSI Alliance fleet, which the same statement put at more than 80 vessels after the alliance grew in 2024.

For a design guide, Jumbo shows how letters and numbers can carry a fleet brand: a family of ship classes running from A to L, with the crane rating written into the class name. Compare SAL Heavy Lift, its alliance partner, and BigLift, another Dutch heavy-lift carrier. For this guide we use a deep sea blue, a warm red and a light sand with a geometric sans, an unofficial interpretation; no product or logo is reproduced.
