MONTRÉAL, Aug. 20, 2025 /PRNewswire/ -- The CSL Group ("CSL") has deployed its newest addition to the fleet, MV CSL Flexvik, to support marine construction and aggregate logistics across Europe. This 18,003 DWT hybrid self-loading/unloading vessel has been engineered to deliver maximum versatility, capable of handling a wide range of cargo, from fine sand and gravel to 1-3 tonne armour rock.

Delivered on May 31, 2025, from Wulkan Shipyard in Szczecin, Poland, MV CSL Flexvik is the result of a strategic conversion from a conventional bulk carrier into a purpose-built vessel optimized for flexible, cost-effective delivery of materials for infrastructure and offshore energy projects.

Fitted with two gantry-mounted Sennebogen 870 electric excavators, MV CSL Flexvik can self-load and self-discharge with precision. Cargo can be offloaded via the conveyor belt system, which includes a 45-metre discharge boom, or directly using the onboard excavators. This means the ship can single-point discharge to a stockpile, transload materials to another vessel, and efficiently handle larger rock gradings, discharged directly using the excavators.

"CSL Flexvik brings a new level of operational flexibility to Europe's marine construction logistics," said Louis Martel, CSL's President and CEO. "Its hybrid configuration, flexible rock-handling capabilities, and direct discharge options offer unmatched flexibility for project-based and industrial customers."

Key Advantages:

• Handles Full Range of Materials: Capable of transporting everything from sand and crushed stone to heavy rock armour.
• Multiple Discharge Options: Offers boom discharge, directly over-side or vessel-to-vessel transhipment.
• Supports Subsea Rock Installation Logistics: Can tranship rock to other vessels, enabling subsea rock installation vessels to remain in situ.
• Reduces Port Time and Costs: Self-operating excavators reduce reliance on shore-based stevedores.
