Project Logistics Alliance’s partner SAL Heavy Lift, one of the world’s leading maritime heavy lift and project cargo carriers, has signed building contracts for four firms plus two optional new generation heavy lift ships with Wuhu Shipyard, China. This joint newbuilding programme involving SAL Heavy Lift and partner Jumbo Shipping is called Orca Class.

Scheduled for delivery starting in mid-year 2024, the first two ships will be exclusively involved in the transportation of offshore wind turbine components in a long-term commitment with Siemens Gamesa Renewable Energy. Two additional sister vessels will enter the premium heavy lift shipping market to serve the clients of the Jumbo-SAL-Alliance in the first half of 2025.

“The Orca vessels are setting new standards in global heavy lift shipping. They represent the new benchmark both in terms of their technical capabilities and modern climate-friendly propulsion systems,” says Dr Martin Harren, Owner and CEO of SAL Heavy Lift and the Harren Group. “The ships will be the most efficient vessels in their class with consumption and emission figures far superior to any existing heavy lift vessel today. As a signatory to the ‘Call to Action for Shipping Decarbonization’, our Group has committed to the decarbonization of shipping activities by 2050. I am proud that this new building order shows how we are keeping our promise for significant, concrete action.”

The vessels were developed in close cooperation with SAL’s joint venture partner, Jumbo Shipping (Schiedam, The Netherlands), another true heavyweight in the industry. The vessels measure 149.9 metres x 27.2 metres and provide a capacity of 14,600 dwt. Despite their compact outer dimensions, the vessels have a box-shaped single cargo hold with the largest dimensions in its class. Provided the hatch covers with a capacity of 10 t/m² are not utilized for stowing super-heavy deck cargoes, such as 3,000 t cable carousels, the vessels can accommodate over-height cargo in the hold and sail with open hatch covers up to full scantling draft.

Ice class notation 1A, a Polar Code certification, and the reduced design temperature of the hull and equipment allow the ships to safely operate in cold conditions as well. Two 800 t Liebherr cranes specifically designed for this ship type can handle cargo items weighing up to 1,600 t in tandem.

In addition to the optimized hull design, the Orca vessels will have an innovative propulsion system consisting of compact and efficient main engines and a diesel-electric booster function. Compared to other heavy lift vessel designs, this hybrid setup features the widest available range of economic speed settings and redundancy. At a service speed of 15 kn, the vessels will consume significantly less than 20 t of fuel oil per day – similar to far smaller-sized and geared MPP vessels. Alternatively, the vessels will be able to trade at a slow, ultra-efficient speed of 10 kn at 6 t while still being able to reach a maximum speed of 18.5 kn for urgent deliveries – if a windfarm installation vessel is waiting for an urgent component delivery, for example.

The vessels are equipped with dual-fuel engines, which means that they can use methanol as an alternative fuel. If green methanol becomes available in key ports as anticipated towards the end of the decade, the Jumbo-SAL-Alliance will be able to offer their customers carbon-neutral transport solutions – a defined environmental protection goal that both companies share.
