Rolls-Royce receives patent for wave piercing bow design in China

Wednesday, 12 March 2014

Rolls-Royce has been granted a patent in China for the Environship wave piercing bow technology for merchant vessels, in recognition of its unique and innovative bow design. The Environship concept, which can be adapted for different ship types, incorporates a range of Rolls-Royce technologies to deliver efficiency savings for ship owners.

The design features a bow with a vertical stem for a smooth entry into the water. When a wave is encountered, the hull shape pierces through the water rather than rides over the top, while the bulb contours the shape of waves along the ship's side to reduce wave resistance. The straight flare in the bow design also minimises speed loss and slamming during operation.

Per Egil Vedlog, Rolls-Royce, Design Manager, said: "We are pleased to receive this patent because it represents a benchmark for quality and legal protection. This patented technology will be highly relevant for ship owners looking to improve the efficiency of cargo ships operating along coastlines and inland waterways where it is most important to reduce fuel consumption and emissions."

This is the second of three patents granted for the wave piercing bow design, with patents also successfully registered in Europe last year and Russia this year. 

  1. Rolls-Royce's vision is to create better power for a changing world via two main business segments, Aerospace and Marine & Industrial Power Systems (MIPS). These businesses address their markets with two strong technology platforms, gas turbines and reciprocating engines, for use on land, at sea and in the air.
  2. Aerospace comprises Civil Aerospace and Defence Aerospace. MIPS comprises Marine, Energy, Nuclear and Power Systems. Power Systems includes Rolls-Royce's 50% ownership of Rolls-Royce Power Systems (RRPS), a joint venture with Daimler AG. RRPS was fully consolidated in the results of Rolls-Royce plc for the first time in 2013.
  3. Rolls-Royce has a broad customer base comprising more than 380 airlines and leasing customers, 160 armed forces, 4,000 marine customers, including 70 navies, and 1,600 energy and nuclear customers in 120 countries.
  4. Annual underlying revenue was £15.5 billion in 2013, around half of which came from the provision of aftermarket services. The firm and announced order book stood at £71.6 billion at 31 December 2013.
  5. Rolls-Royce employs over 55,000 people in offices, manufacturing and service facilities in 45 countries. Over 17,000 of these employees are engineers.
  6. In 2013, Rolls-Royce invested £1.1 billion on research and development. We also support a global network of 29 University Technology Centres, which connect the company's engineers with the forefront of scientific research.
