Feature 1 | MEDITERRANEAN AND BLACK SEA Croatian yard gets scrubber contract
Te Viktor Lenac Shipyard has received a contract for a scrubber conversion that promises to open the door for further work of this type in the future.
V
iktor Lenac will install an exhaust gas cleaning system, or scrubber, on the bulk carrier
Balder, owned by Norway’s Klaveness Ship Management. Te yard, which is one of the first in the Mediterranean to carry out this type of conversion, expects to receive the ship in May this year. The job consists of replacing the
existing funnel and installing a completely new one, complete with the scrubber, which is being supplied by Norway’s Clean Marine. Conversion of the exhaust gas system also includes the installation of associated peripheral equipment, such as cooling pumps, control and supervisory systems. The yard is also currently working
on another significant conversion, involving the offshore gas and oilfield installation vessel, Sampson, which is being converted into a crane and pipelaying
vessel. Six new diesel
generators - 2200kW each - are being installed in two independent engine rooms, along with new ship systems with more than 40tonnes of piping. The yard will also fit two new thrusters in place of existing fresh water tanks, a new A&R winch room will be built and outfitted in the existing hold no.1 and various items of pipelaying equipment, including tensioners, track supports, conveyors and a pipe loader, will be installed together with hydraulic systems on the main deck. Viktor Lenac will also build and install a new 300tonne capacity pipe lay tunnel and A-frame structure, as well as stinger equipment for laying offshore pipelines. Finally, two engine rooms, two
switchboard rooms and two thruster rooms will be outfitted and an HVAC system will be installed in new ship spaces. In total Viktor Lenac estimates that more than 150km of cables will be laid by the yard during this project. As well as offshore conversion work,
where it has an established track record of completing major projects, Viktor

The Viktor Lenac yard will have a third floating dock by the middle of this year.
Lenac is aiming to establish itself as a leading yard for naval work. In this context a recent contract to provide maintenance and overhaul services for the US Sixth Fleet flagship, USS Mount Whitney, is hugely important. To better meet the needs of its various
target markets, Viktor Lenac shipyard is taking steps to further increase its docking capacity. Specifically, in November 2011 the company signed a contract for the purchase of a new floating dock from a Ukrainian shipyard. The new 8500tonnes capacity dock, which measures 155.5m in length and has an internal clear width of 24.5m, is due to be completed in May
2012 and then towed to Viktor Lenac. The dock will focus on small to medium sized ships, particularly chemical and LPG tankers, ferries, general cargo and container ships, and offshore support vessel conversions. Te shipyard currently has two floating
docks. Dock 11 is the largest dock and can receive vessels of Aframax and Suezmax size, while the smaller Dock 5 has recently been extensively renovated. With the third dock, which will be put into operation in June, the shipyard expects to benefit from increased flexibility in accommodating small to medium sized ships, freeing up the larger dock capacity for bigger vessels.
