German heavy-lifter takes world title
In December 2010 the J.J. Sietas Neuenfelde shipyard near Hamburg delivered the heavy lift ship ‘Svenja’ to Germany-based heavy lift company Schiffahrtskontor Altes Land (SAL), a joint venture with the Japanese 'K'-Line group.
The newbuilding is claimed to be the largest and fastest heavy-lift vessel of its kind, boasting a lifting capacity of 2,000 tonnes and able to maintain a 20 knot speed, a combination that is thought to be ship unique in this sector. Built in a six month time period at a cost of € 60 million ($83 million), the Svenja is the first in a two-ship series based on the Sietas type 183 design developed in close co-operation between the owner and shipbuilder with up to 75% of the parts employed in its construction originating from Germany. The second vessel, named Lone, was scheduled to enter service during March 2011.
The ship is fitted with two portside mounted 1,000 tonne electrical-hydraulic high capacity cranes manufactured by Neuenfelder Maschinenfabrik (NMF), a Sietas group company, giving a combined crane capacity of 2,000 tonnes SWL. Besides being tested to 1,100 tonnes lifting capacity each, the cranes are characterised by their outreach, 16m at 1,000 tonnes and 38m at 500 tonnes.
The 2,000-tonne heavy lift capacity is said to surpass the 1,800 tonne capacity vessel owned by Dutch firm Jumbo Shipping. “We decided to stop at 2,000 tonnes but we might see vessels with higher lifting capacity in future,” said Lars Rolner, managing director of SAL.
The vessel’s prime mover is a 12,600kW MAN 9L58/64 four-stroke medium-speed diesel mechanical engine driving a Schottel SCP 154-4 XG CP propeller for a speed up to 20 knots. Auxiliary power is provided by means of two 1,100kW Mitsubishi S12R MPTA medium-speed diesel gensets which will provide power for the Brunvoll 1,200kW bow thruster and 800kW stern thruster. In addition, the vessel is fitted with one smaller 595kW Mitsubishi S6R2 MPTA genset and a 233kW MAN D2866 LXE 20 emergency generator.
Together with the high efficiency rudder, designed and manufactured by the shipbuilder, the thrusters are intended to offer enhanced manoeuvrability and a DP1 capability controlled by a Kongsberg dynamic positioning system. It will be possible to upgrade the Svenja’s DP system to DP2 at a later stage. Sister ship Lone will be DP2 equipped from the outset. This capability will allow customers to use the vessels as a combined solution for both transport and offshore installation including sub-sea handshakes. They will be suitable for offshore wind turbine installation works, in particular for installation of piles, mounting of transition pieces and the transport of components from shore to platforms.
Further features include three-fold adjustable tweendecks enabling the Svenja to operate as an ‘open-top’ ship which means the ship can transport particularly large loads and trade with open hatches. In addition to its high performance, the vessel possesses an ‘environmental passport’ meeting high environmental standards. It also possesses ISO 14001 and OHSAS 18001 HSE certifications. These ensure that both ships will be ready for employment in future markets including wind energy, offshore oil and gas industries, industrial plants and other sectors.
The 12,975 dwt heavy lifter measures 160.5m in length and 27.5m in width, has a loading capacity of 11,000 tonnes, 40,000m3 freight volume, a 128.5m x 27.5m weather deck and a single large hold measuring 107.1m x 17m x 13.7m giving a 12,800m3 capacity.
“For our customers, we offer high-performance heavy lift vessels for the most demanding of tasks. Our competitive advantage is clearly the outstanding quality of the ships, coupled with our expertise as specialists in development, technology, ship management, project planning, worker protection and environmental standards.” says Rolner.
According to Rolner, “The global economic crisis has also had an effect on the heavy lift sector. However, we are already seeing signs that the market will recover in 2011. We have already received enquiries for expansive orders from the wind-energy sector, as well as from the oil and gas industries. To make sure that we are properly equipped, we are investing in two innovative heavy lift vessels, with which we can consolidate our leading position in the world market.”
During 2008 SAL received three ships from the Sietas shipyard, and one more in 2009. Altogether, the Sietas yard has built around 50 ships for SAL since the early 1980s.
