SEA1 OFFSHORE 250Mt KBC Pressrelease

HUISMAN WINS REPEAT ORDER FOR TWO MORE KNUCKLE BOOM CRANES FOR SEA1 OFFSHORE

May 6 2025

Huisman has secured another contract for the delivery of two 250mt Knuckle Boom Cranes, which will be installed on the new ST-245-designed offshore energy support vessels of SEA1 Offshore. The contract was signed with COSCO Shipping Co., Ltd., and follows a previous order for two identical cranes awarded at the end of 2024.

The cranes will feature Huisman’s proprietary Active Heave Compensation system. This system connects the crane’s electric setup to the vessel’s DC grid, enabling efficient interaction with the vessel’s electrical energy storage system. This integration significantly reduces the net energy consumption of offshore lifting operations. 
 
Cees van Veluw, Product Director Cranes at Huisman, says: “We are proud to work alongside SEA1 Offshore, COSCO Shipping and Skipsteknisk, combining our expertise to deliver reliable, energy-efficient lifting solutions. The trust placed in us for a repeat order confirms the strength of these partnerships and our shared commitment to innovation in the offshore energy sector.”
