Side by side, three of the most prominent and technologically advanced breakbulk and heavy lift carriers, Jumbo Shipping, SAL Heavy Lift and Intermarine, are combining their strengths and resources to deliver the best maritime transport solutions to customers worldwide. Three united teams and three fleets operate as one shared fleet – specialised in their respective business fields. And customers benefit from simplified, full-scope services. JSI Alliance controls and operates around 50 owned and chartered project cargo vessels – of these, 25 high-end project cargo vessels. With three DP2 vessels, four semi-submersible deck carriers, two range-extending Fly-Jibs and eleven ice-class vessels, JSI Alliance can reach almost any location and master the most demanding scopes. JSI can also organise time charter vessels if needed.

JSI Alliance provides highly flexible shipping solutions and an unparalleled range of breakbulk and project shipping services in the market. Lifting capacities from standardised multipurpose ships range from 160 t SWL to 3,000 t SWL. As such, JSI Alliance manages the largest fleet of vessels in the +800 t lifting segment as well as the most advanced green heavy lift ships, with Orca series vessels launching in 2024. This provides a commercial bandwidth that stretches from rapid positioning vessels for smaller or larger single shipments to large volume contracts and full-scope solutions for complex projects – all under one roof. A strong group of experienced professionals – commercial, engineering, project management, QHSE – works closely together with a combined network of agents and offices worldwide. They provide partnership, expert advice and safely delivered goods to a wide range of clients, including EPCs, brokers, forwarders, OEMs, energy companies and more.
