Jumbo

What Jumbo does

Jumbo Maritime is a Dutch family-owned maritime contractor founded in 1968 and headquartered in Schiedam, Netherlands, operating through five B.V. legal entities (Kahn Scheepvaart B.V., Jumbo Shipping Contractors B.V., Jumbo Offshore Installation Contractors B.V., Jumbo Crew Services B.V., and the Jumbo Maritime umbrella). The company runs two divisions: Heavy Lift Shipping and Offshore Installation Contractors. The shipping division deploys in-house designed HLVs with dual Huisman crane capacities ranging from 650 to 3,000 tonnes, including the K-Class (3,000t combined), J-Class (1,800t), and H-Class (800t). The offshore division operates two DP2-equipped Heavy Lift Construction Vessels (Fairplayer and Jumbo Javelin) capable of installation work in water depths up to 3,000 metres. The combined technology stack includes DP2 dynamic positioning, wind-assisted propulsion, methanol-ready newbuilds, and an in-house 'Can-Do Engineering' capability covering mechanical, structural, civil, ship motions, and marine engineering disciplines, supported by the company-developed Stay Well safety programme.

The business model is project-based and B2B. Revenue is earned through transaction-fee heavy lift shipping contracts and offshore transport & installation (T&I) contracts negotiated 3-5 years ahead of award, with pricing adjusted per project for cargo characteristics, route, vessel requirements, and EU ETS carbon costs. Distribution is conducted via direct enterprise sales (Commercial Managers, Business Development Managers including Houston-based coverage of the Americas), the JSI Alliance commercial platform combining Jumbo, SAL Heavy Lift, and Intermarine into a single entry point with offices and agents in more than 20 countries, and long-term client relationships with major EPC contractors and energy majors. Customer segments are diversified across oil & gas, offshore wind, LNG (including FLNG), refinery and petrochemical, cranes, rolling stock, and government clients, with named customers including Shell, TechnipFMC, Samsung, MODEC, Petrobras, Vattenfall, Van Oord, Jan De Nul, JGC, Golar LNG, Southern Energy, Pan American Energy, and the French Navy.

Jumbo is investing heavily in fleet renewal and decarbonisation: the Orca class newbuilding programme (four methanol-capable vessels with SAL Heavy Lift, initiated 2022) and the May 2026 order of two new L-Class 25,000 DWT vessels with dual 1,200-tonne Huisman cranes (deliveries 2028 and 2029) point to a forward capacity expansion. Strategic partnerships with Intermoor (Acteon) for mooring and anchors and with Sea Horizon for Middle East operations, alongside the Argentina FLNG consortium contract, indicate active geographic and capability expansion. The company is led by CEO Peter de Bree (effective January 2025), operates as a private family-owned enterprise with no parent or external controlling entity, and targets carbon neutrality before 2050.
