From general cargo ship to cement carrier in just three weeks

The visit began with a comprehensive maintenance programme including a full survey and a range of repairs and maintenance to prepare her for more years of reliable service. These works included fitting a new fuel filter system, renewing the hydraulic pipes for the hatch crane, and repairing the propeller while at the same time replacing the seals and liner for its shaft and changing the shaft seals for the bow thruster. The hull and topsides also received a fresh coat of paint.

The main project, however, was the installation of eight new cement silos, each with a capacity of 40m³. These tanks were previously fitted on the VOS Symphony, another regular visitor to Oranjewerf, prior to it going for scrap. The yard removed the tanks, refurbished them and then fabricated a silo foundation and fitted it in the vessel’s hold. 80-metres of stiffeners were also welded into place in the double bottom tanks to provide the necessary support, and then the eight tanks were positioned and fixed in place.

To complete the installation, approximately 100m² of grating walkway was fabricated and fitted on the deck to give acess to the manifolds on each of the new silos. The supply/ discharge and air pipe system for the two existing silos was also refurbished to accommodate the new capacity.

Joined-up thinking

Converting the Lelie-C in this cost-effective manner was made possible by the team at Oranjewerf recognising that a project taking place on one vessel, in this case the VOS Symphony, presented an opportunity for another, the Lelie-C. By putting the two clients together, an agreement was reached that benefited both parties, and Oranjewerf was able to undertake the works in a timely and efficient manner. A good result for all involved.
