Power-to-X to be the carbon-neutral energy storage technology of the future

Many climate experts predict that the next ten years are crucial, thus our actions within this decade will decide whether we are able to reach the ambitious goals of the Paris agreement limiting the global temperature increase to 1.5°C until 2050. Yet, recent studies show that G20 nations are currently failing to reach their climate goals.

Norsepower, SWS develop energy-efficient VLCC project

Norsepower Oy Ltd., announces a joint development project with Shanghai Waigaoqiao Ship Building Co., Ltd (SWS) both developing an energy efficient dual fuel very large crude carrier (VLCC) design, aiming to enhance fuel efficiency and reduce emissions. Under the agreement, Rotor Sails were implemented in the VLCC design for improving the fuel efficiency and reducing emissions.

Shaft generators help limit shipping emissions

In a statement, Wärtsilä highlights that it has been a stellar year for its shaft generators, generating power for a ship’s auxiliary systems from its main engines, which can also be used to reduce shipping emissions. Michael Kranz, Manager, Shaft Generator Systems & Cargo, overseeing a department of eight engineers at Wärtsilä’s Marine Electrical Systems highlighted that “last week, we reached 500 units sold, an incredible milestone. In the same week, we sold a comprehensive (holistic) hybrid system to a series of hybrid RoRo vessels. After a relatively slow start to the year, we are now seeing a big increase in these systems being specified by owners interested in reducing emissions and fuel costs.”

HHI launches simplified power system for containerships

Hyundai Heavy Industries launched a simplified power system to be used by 15,000 TEU containerships, and received Approval in Principle by DNV GL. Traditionally, for conventional containerships, onboard electrical equipment is powered at a low voltage level. Yet, as containerships are becoming bigger, this means that the electricity they consume is increased.

Next-gen energy-saving bulker delivered

Japan Marine United informed that it delivered the next-generation energy-saving bulk carrier, Emperor Pampero, on August 29, built at the Tsu Works. The ship is equipped with a scrubber. It also features an optimal hull form, in order to achieve low resistance and high efficiency, while also significantly improving fuel efficiency. The latter will be done through the use of energy saving devices. 

Two new green cruise ships to operate in Norway from 2021

Turkey-based Tersan Shipyard is building two new LNG-fueled cruise vessels for Norwegian shipowner Havila Kystruten, expected to operate the historic coastal voyage between Bergen and Kirkenes, along the western coastline of Norway, stopping at 34 ports along the route.

Wartsila presents new tech, enhancing dredging efficiency

Wärtsilä presented the Wärtsilä HY for Dredger, a new product based on Wärtsilä’s HY hybrid propulsion technology. Its goal is to improve the efficiency and sustainability of dredging operations. The new technology is able to optimise performance throughout the vessel’s lifecycle. 

Jan De Nul launches fourth ultra-low emission vessel

Jan De Nul Group announced the launch of its fourth low-emission vessel in Singapore. The vessel is the 6,000 m³ Trailing Suction Hopper Dredger Sanderus built at the Keppel Offshore & Marine shipyard. Sanderus combines a shallow draught with high manoeuvrability, making her very suitable for working in confined areas.
