Solving the challenges our customers face is at the heart of everything we do. We design complete solutions to provide measurable value where it matters most.
Our goal is designing the best possible ship, which is why we cover every aspect of the process, from concept through to design, equipment selection, procurement, systems engineering, integration to production engineering.
Our approach reduces costs, maximises efficiency and caps risk, delivering solutions that strike a perfect balance between performance, investment and ownerships costs, all backed by an international customer support network.
We test and verify the motion of all our ships, continually improving our designs to solve the challenges facing our customers and evolve the design of our vessels to ensure optimal performance, safety and comfort, no matter the conditions.
With more than 900 designed vessels at sea, we know what it takes to integrate systems so that all major, mission critical components interact correctly, meaning we can ensure efficiency, reliability and safety.
State-of-the-art technology demands state-of-the-art training, so we offer a range of tailored training courses and programmes using the latest simulators and training aids, as well as giving our customers the opportunity to access online training services.
More than 900 UT and NVC vessels are in operation all over the world – under the toughest conditions known to man. We continue to work closely with vessels’ operators and crew, forming a vital knowledge base from which we continually improve and refine our designs, passing those benefits on to everyone we work with.
The Nor Lines fleet renewal programme is showing the way forward for Europe’s coastal and short sea cargo fleet
Background
When it came to updating its fleet to meet current and future needs with minimum environmental impact, Nor Lines enlisted our ship design skills, along with our leading gas engine and propulsion technology to realise its goals. Efficiency was at the heart of Nor Lines’ requirements, and is also at the heart of everything we do, from design to systems integration.
Minimising emissions while still hitting the required service speed of 14.3 knots means using the least possible amount of energy when transporting cargo. To do that, the hull propulsion and engine efficiencies must all be high, and clean fuel is used to power the vessels. We’ve made significant investments to do just that, optimising hull lines for least resistance, developing world-leading gas engines and developing a new bow design, among many other features. The investment has paid off, with a study on its operation profile showing a reduction in CO² emissions of around 40 per cent compared to conventional vessels.
“This project, developed together with Rolls-Royce, will provide Nor Lines with an improved tool for future operations, both with regards to energy consumption and emissions, as well as handling efficiency."CEO of Nor Lines, Toralf Ekrheim
Challenge
Shipping company Nor Lines needed vessels to meet its current and future needs. Operating in Emission Control Areas, efficiency and reducing exhaust emissions were vital, but the vessels still needed to be capable of travelling at their required service speed. What’s more, Nor Lines carries a great variety of cargo, from offshore construction equipment to frozen goods, meaning the new fleet had to maximise efficiency in handling any cargo type.
Solution
Nor Lines commissioned two vessels to be built to our NVC 405 LNG design. Among many optimised features the vessels are powered by a single Bergen B35:40 V12 lean burn gas engine, reducing CO² by around 22 per cent and NOx by over 90 per cent in comparison to liquid fuel engines. The engine can operate at variable load and speed and mechanically drive the propeller, meaning both can be run at their design conditions for maximum efficiency, while the design of the gas supply system means the engine can be installed in an ordinary engine room.
Our support teams, located worldwide, are committed to helping you manage the vital balance between operational availability and cost. Wherever your vessel is located, Rolls-Royce support is close at hand.
