Zinus develops next generation shore power solution for cruise ships

Posted on:

Norwegian company Havnekraft has awarded Zinus the contract of developing and delivering a new and flexible shore power solution for cruise ships calling at Haugesund Cruise Port. Several international ports are also showing interest in the solution.

For several years, Zinus has offered the Shore Power Cruiser – a specially developed, mobile and flexible system for transmitting high-voltage shore power to cruise ships and other large vessels. The company is now taking the technology one step further, in line with a recent contract with Havnekraft in Haugesund, Norway – a company owned by Karmsund Port Authorities and the energy company Haugaland Kraft.

“Havnekraft wants to offer shore power to cruise ships calling at Garpeskjærskaien in Haugesund and has given Zinus the task of developing the next generation shore power connection for this type of vessel. The new system will be an “all-in-one solution” that focuses on fast connection, easy user operation and reduced operating costs. The product must also be able to manage large power variations and give Havnekraft a high degree of flexibility,” said Ronny Olson, sales director at Zinus.

“We chose Zinus because the company is one of the forerunners in cable management technology and could offer the best solution for our needs, and it is extra gratifying to be able to award the contract to a local player. For us, it has been important to ensure fast and efficient connection of the cruise ships, and that the large high-voltage cables are easy and safe to handle for our personnel at the quay. Zinus has presented a very good and functional solution that takes care of all these considerations,” Tine Osmundsen, chairman of Havnekraft, stated.

She said Havnekraft has experienced Zinus as very responsive to input, challenges and changes that have appeared during the development process. “In addition, their concept means that we can remove the cable handling unit when it is not in use, which provides good utilization of the quay also between cruise calls and outside the cruise season,” Osmundsen said.

So far, Karmsund Port Authorities has booked 120 cruise calls in 2022, and around 90% of these ships can receive shore power. The goal is to sell up to nine million kilowatt-hours of electricity during an ordinary season. This will result in a reduction in CO2 emissions of around 2,500 tonnes per season, compared to ships running their diesel generators while docked.

The new generation shore power connection for cruise ships will largely be based on the current solution from Zinus, the mobile, flexible, and efficient Shore Power Cruiser. Four such systems are currently installed in the port of Bergen. In addition to supplying renewable electricity to docked cruise ships, both the existing and upcoming Shore Power Cruiser solutions also contribute to improved port logistics, as well as better preservation and maintenance of cables and plugs, through the systems’ handling and storing of cables and connectors. To further strengthen the environmental and climate friendliness of the shore power solution, the cable management unit from Zinus is equipped with batteries and an electric motor to ensure zero-emission transportation along the quayside.
