BLRT conversion of the bulk carrier Zina
BLRT Repair Yard Klaipeda, Lithuania, recently took on the ambitious conversion of VC Logistic Operations’ bulk carrier Zina for transhipment operations. This extensive project redefined Zina’s capabilities, preparing it for demanding new assignments. It required 313,000kg of steel structure fabrication, 14,230m of cables to be laid and fastened, 6,900kg of pipes to be fitted for the redesigned systems fitted and a considerable number of hours of hard work and expertise.
Structural and equipment upgrades
The journey began with disassembling four shipboard cranes, followed by installing barbettes, bulkhead reinforcements and specialised foundations. Simultaneously, the transverse coamings on cargo holds No. 2 and No. 4 were relocated to optimise cargo operations, and two hatchcovers were modernised to meet updated requirements. The advanced Liebherr CBG 360 cranes were later installed at the Liebherr plant.
Enhanced manoeuvrability and power
To improve the vessel’s manoeuvring capabilities, a bow thruster and thruster tunnel were installed. Additionally, the ship was equipped with an extra mooring winch and twist locks for two container-type diesel generators on the upper deck, enabling increased functionality and operational flexibility.
Electrical and lighting innovations
A highlight of the project was the extensive electrical work. Over 14,230m of cables were laid and fastened to connect the diesel generators on the upper deck, cargo cranes, thruster and deck winch. Visibility and safety were also enhanced by the installation of additional floodlights, barbette lighting and step-down transformers to power crane systems with varying voltage needs.
To support the advanced crane installations and ensure seamless operations, BLRT relocated the radar antennas to the foremast, added new cables and moved the masthead lantern atop crane No. 1. The main steering station was also relocated to the wheelhouse starboard side for optimised control and navigation.
Cool system upgrades
The thruster room received additional fans, cooling pumps for the thruster motor and a thruster frequency converter, ensuring efficient operation under varying conditions.
It required a unified team effort, with engineers, electricians, welders, fitters and project managers all bringing their expertise to the table. “Every challenge was tackled with creativity, precision, and a shared dedication to achieving the best possible result,” says Irina Kostina, Marketing and Communications for BLRT Repair Yards. “This is Zina re-imagined. With these upgrades, Zina is ready to take on a new chapter with enhanced efficiency, manoeuvrability and versatility. This transformation reflects the expertise and dedication of the team at BLRT Repair Yards Klaipeda, delivering solutions that meet the highest standards and setting vessels like Zina on a course for success.”
