Kongsberg supplies engine and thruster assembly for Havila Voyages – Cruise Industry News
Kongsberg Maritime has announced that the Havila Capella, which currently operates a new 12-day shipping route along the Norwegian coast between Bergen and Kirkenes, will use the company’s technology for its motive power and propulsion. Like its three sister ships currently under construction, the Capella was designed by HAV Design AS and deploys integrated and energy-efficient Kongsberg Maritime solutions, according to a press release.
Kongsberg said he was delivering a total of 16 powerful Bergen gas engines to Havila Voyages. These engines apply variable turbo geometry to provide “optimum response at all speeds.”
According to the press release, it is proven that Bergen gas engines produce an energy efficiency rate of around 50%. The liquid natural gas used in these engines reduces CO2 by 25 percent and NOX by 90 percent, in addition to which the engines are able to provide up to four hours of emission-free operation.
“All in all, the greenhouse gas emissions of our Bergen gas engines are about 20% lower than those of diesel engines of the same category, even when we take into account the slippage of methane, the unburned fuel”, said Ottar Ristesund, senior vice president. on sale at Kongsberg Maritime. âThey are much cleaner to use and users report up to 10% reduction in maintenance costs compared to diesel engines. “
The main propulsion of the Capella, on the other hand, comes from a KM Azipull-PM (permanent magnet) unit with an L-drive configuration. According to the press release, the AZP-PM is renowned for its exceptional hydrodynamic efficiency and offers “the advantage of a compact installation footprint as its motor is housed within the diameter of the mounting flange.”
The KM permanent magnet technology used on Havila Capella’s tunnel thrusters “combines practical space savings with quiet operation, low vibration and high performance,” according to Kongsberg. The fast response times of full power tunnel thrusters increase operability and maneuverability, the company said.
âMeanwhile, the shrouds supporting the center shaft are designed to recover some of the vortex energy generated by the propeller, providing additional thrust and improving the energy efficiency of the boat’s hull,â Kongsberg wrote. .
According to the company, wear is also significantly reduced because PM thrusters contain fewer spinning components.
âOur priorities are intertwined: enabling our customers to enjoy the smoothest, safest and most impressive cruises while preserving the unique marine habitats off the coast of Norway,â said Bent Martini, CEO of Havila Krystuten. âWe are grateful to Kongsberg Maritime for providing us with the technology that allows us to provide our passengers with an unforgettable and rewarding experience while simultaneously minimizing environmental impacts. “
âWe are very proud to be closely involved in a cruise ship business which is literally so close to us,â added Ristesund. âProviding efficient, low-emission and zero-emission solutions for Havila’s ships helps ensure that this remarkable landscape is preserved for others to enjoy for generations to come. “
