The Orca class of next-generation heavy lift vessels has just grown stronger with the launch of Carlotta, the fourth ship in the innovative fleet being built to redefine sustainability standards in project cargo shipping.
SAL Heavy Lift GmbH officially launched Carlotta this week at the China Merchants Jinling Shipyard (CMJL) in Weihai, marking a pivotal milestone in the company’s Orca newbuild program. The launch brings the total number of operational Orca vessels to four, with only one more remaining in the series.
The Orca series is a direct response to growing calls from cargo owners and freight forwarders for more sustainable ocean transport solutions. Each vessel in the class is designed for significantly lower greenhouse gas emissions, optimized fuel efficiency, and maximum adaptability in handling complex breakbulk and project cargoes.
With a deadweight capacity of around 14,100 metric tons and dual-fuel capabilities prepared for future alternative fuels, the Orca ships are built to comply with IMO Tier III emission standards. SAL has indicated the design includes fuel-saving hull lines, a fully electric cargo crane system, and readiness for methanol operation—important steps as the industry moves toward decarbonization goals.
The launch of Carlotta is particularly notable because it brings the Orca fleet nearly to completion. Once the fifth and final vessel is delivered, SAL will have one of the most modern and environmentally friendly multipurpose heavy lift fleets in operation globally. These ships are already helping charterers and industrial clients meet their Scope 3 emissions reduction targets without sacrificing cargo capacity or operational flexibility.
The Orca class also offers flexibility in loading and routing that’s critical in a post-pandemic supply chain environment. Ships can be quickly repositioned, call at underdeveloped ports, and handle out-of-gauge and super-heavy items thanks to advanced deck layouts and heavy-lift gear rated up to 1,000 metric tons combined.
Over the past two years, Orca-class vessels have been involved in a wide range of transport operations, including wind energy components, transformers, reactors, and infrastructure modules. Their ability to support renewable energy and large-scale industrial projects has made them increasingly relevant to EPC contractors, energy developers, and governments prioritizing green transition initiatives.
As Carlotta completes sea trials and enters service later this year, she will join a small but growing number of vessels globally capable of delivering both performance and sustainability in heavy lift transport.
