Northern Offshore Services' Green Technology initiative will transform our company into a sustainable shipping company ready to meet the future and lead the way for a greener, more sustainable industry. We have two focus areas for the coming years.
Firstly, to develop and produce vessels with low environmental impact, still with high offshore availability, safety, and range. We set the standard with the unique, state of the art and future proof N-O-S CTV’s.
Our second focus area is to prepare and adapt our existing fleet for alternative energy sources. We are now developing, constructing, and converting vessels for higher performance and emission reduction equipment to lead the way and help make the industry become more sustainable.
The I-Class series
The I-Class vessels will be highly effective and the design of the vessel will save up to 50 % fuel, compared to other high performance vessels on the market.
What is the next step? To enable the highest offshore availability in Zero emission mode there is a need for offshore charging. The electrification of the shipping industry needs it. Northern Offshore Services research and development for different offshore charging options are ongoing.
We want to provide our clients with reliable marine battery solutions. Together with our preferred shipyard, our R&D department has developed the N-O-S Energy Simulation software. This enables calculations of the battery capacity required for specific wind farm projects. The system allows us to enter parameters such as distances, push-ons, transits and calculate the battery capacity needed to run a full day in the field. With the N-O-S Energy Simulation clients can feel safe that we provide safe, reliable, and efficient service and solutions at sea.
We believe in Electrification. But until we are fully there, we need to explore and assess the alternatives to provide our clients with environmentally effective and reliable solutions. We focus on how to adapt our existing fleet to alternative fossil-free energy sources today. Whether it is methanol, green hydrogen, or HVO we evaluate all alternatives when it comes to environmental benefits and plan for upgrades of our entire fleet.
The second focus area for N-O-S sustainable future is to take care of what we have and update our current fleet. We have about 45 vessels that will be upgraded. We have a plan in place and we have already started.
Two vessels from our M-Class series, Mover and Maker are the first in line for battery preparations. During early 2022, we will carry out a complete upgrade of the two. The vessels will have a new Volvo Penta IPS propulsion system and be prepared for battery installation. The preparation entails making rooms for batteries and preparing the main engines for diesel-electric propulsion. In short, enabling the engines to run on a combination of fuel and electricity.
In 2020 one of our A-Class vessels – Assister – was rebuilt and upgraded. The vessel was extended from 19 meters to 25 meters, utilizing recycled aluminum. The vessel upgrade included a new driveline with 4 x Volvo Penta IPS system and the interior was refurnished with 12 additional seats, making former Assister, now Traveller to a 24 Pax CTV. The transformation from Assister to Traveller gave the vessel a whole new lifespan.
