Rolls-Royce informs it has been granted a patent in China for the Environship wave piercing bow technology for merchant vessels. 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 first of four new catamaran ferries being constructed by Gondan for owner Baleària has been launched by the shipyard's GRP Division. The four ferries, which are due to be delivered between the end of this year and the middle of 2018, are designed to operate on short distance trips in the Balearic Islands. According to the builder, the 28-meter-long GRP ecofast ferries have capacity for 350 passengers and are designed focusing on eco-efficiency, comfort and speed during navigation.

Farstad Orders Unique Wave-Piercing Offshore Vessel

Rolls-Royce received from Farstad Shipping the first order for its new wave-piercing offshore vessel. The bow design will reportedly enable the vessel to pierce through waves in extreme weather conditions, while maintaining constant speed, reducing fuel consumption and enhancing safety. The contract, worth in excess of &19.1 to Rolls-Royce, includes vessel design and a comprehensive integrated power and propulsion system and equipment package for an advanced platform supply vessel (PSV). The contract also includes an option for a second vessel of the same specification and value.

COSCO Selects Rolls-Royce Package

Rolls-Royce won an order to provide an integrated design and equipment package for two offshore supply vessels to be built at COSCO (Guangdong) Shipyard Co., Ltd in China for Singapore based Chellsea Group. The two Rolls-Royce UT 771 WP platform supply vessels features the striking wave piercing bow designed to pierce through waves in rough seas, making it possible to keep a more constant speed, reduce fuel consumption and increase on board safety.

Innovative Cat Crewboat Launched by Topaz

Incat Crowther announced the launch of Topaz Zenith. Launched by Topaz Shipbuilding, this 27.6m Wave Piercing Catamaran Crew Boat has been designed to support offshore energy installations. Part of the development of the vessel focused on an unusual platform for the application. Following the evaluation of a series of criteria, a Wave Piercing Catamaran platform was chosen. The bow of the vessel is configured to interface cleanly with the rig structure, while being well clear in all other areas to avoid risk of collisions and injuries.

Innovative Enviroship Concept Wins Big

Per Egil Vedlog  Design Manager, Rolls-Royce Marine AS

Earlier this year Rolls-Royce was bestowed the Heyerdahl Award for its Enviroship concept. Maritime Reporter & Engineering News  recently caught up with Per Egil Vedlog, Design Manager, Rolls-Royce Marine AS, for his insights on the honor as well as the challenge in designing for the maritime future. Anyone that has spent much time in Norway must realize that the Norwegian maritime cluster is a special one, bound by generations of designing, building and operating in, around and under the sea.

New Wave Piercing Design for Offshore

In at Norshipping 2009 Roll-Royce debuted an innovative wave piercing design for the offshore market, the new UT 790 CD vessel design. “With the UT 790 CD, we can support offshore exploration and production further and deeper while at the same time improving safety and minimizing the impact on the environment,” said Svein Kleven, Rolls-Royce Chief Design Manager – Offshore. The unique hull piercing design is designed to allow the vessel to run continuously at service speeds regardless of the sea state reducing fuel consumption and improving crew comfort.

Incat Crowther Designs Catamaran Crew Boat

Incat Crowther announced that the firm has been contracted to design an innovative 91.8 ft Wave Piercing Catamaran Crew Boat to support offshore oil and gas operations. Developed in conjunction with Topaz Shipbuilding for a large petroleum firm, the vessel features a new layout. As the original inventors of the Wave Piercing Catamaran, Incat Crowther proposed the platform in response to a challenging combination of operational requirements. The first challenge was to balance a restriction on beam with the requirement to locate an oil spill recovery container transversely on the aft deck.

Transonic Hull Technology for Offshore Vessels

Hydrodynamics theory establishes that wave making resistance of displacement hulls originate from their body shape, especially from shoulders, midbody, and rear quarter curvatures of their waterplane at the water-air interface.  These curvatures create bow waves, midbody troughs, and stern waves, which set the “hull speed” limit when the distance between bow and stern wave equal the boat’s length (speed/length ratio 1.34).  Above hull speed, resistance grows at a high exponential rate.  Transonic Hull (TH) technology eliminates this problem by using a slender triangular waterplane with apex at the bow, and rectilinear sides, free of curvatures, extending from bow to a maximum beam at the stern.  This shape also generates the sharpest possible entry angle at the bow.

Incat's Wave-Piercers Cross Atlantic at Record-Breaking Speeds

Incat Australia Pty. Ltd. is widely regarded as a premier builder of high-speed ferries, and that reputation was enhanced with the production of three wave-piercer catamarans, which hold the distinction of being the fastest ships ever to cross the Atlantic. The two latest, Catalonia and Cat-link V, are from Incat's line of 299 ft. wave-piercer class of fast-ferry vessels. They made their individual record-breaking journeys across the Atlantic within weeks of each other, at average speeds of 39 knots and 41 knots, respectively. The wave-piercer fast-ferry vessels have been launched from Incat docks in Hobart, Tasmania, Australia, since September 1997.
