Optimized Outboard and Sterndrive Power

A portion of the energy created by a propeller is lost from upward flow. The Whale Tail XL from Davis Instruments is a stabilizer and ski boat fin that takes this wash and powerfully directs it aft.Whale Tail XL's unique hydrodynamic design generates lift for improved acceleration to plane and increased top speed. Waterskiers pop out of the water easier and in less time, and enjoy a flattened wake.With the Whale Tail XL, pitch and roll is decreased. This provides a level, comfortable ride with skid-free turns, especially in rough water.Handling is enhanced with the Whale Tail XL.

Faster Propeller Repairs in the Middle East

Aiming to provide faster repair service in the Middle East to ship operators whose vessels have sustained propeller damage, Stone Marine Shipcare has signed a Service Agency Agreement with Dubai Drydock World which sees one of the companies’ mobile workshops permanently based there. The workshop will be used, not just at Drydock Worlds’ own facilities, but can be quickly transported to other Middle Eastern shipyards, wherever a ship is in need of repair or maintenance to its propeller.

Moving Ahead Powerfully

The layout of ship propellers is a balancing act between optimal power conversion and the avoidance of unwanted cavitation effects, which can result in damage to the propeller structure and higher noise levels. MAN Diesel & Turbo in Frederikshavn, Denmark, is using the computational fluid dynamics (CFD) simulation solution STAR-CCM+ from Siemens PLM Software to model cavitation and optimize ship propellers. Two mid-size container ships of 8,500 TEU – CSCL Europe and CSCL America – will be upgraded by retrofitting a efficient Kappel propeller.

HMS Queen Elizabeth Sets Sail with Dellner Brakes

U.K. Royal Navy aircraft carrier HMS Queen Elizabeth arrived at her home port of Portsmouth last week, fitted with two Dellner Brakes ‘stopping, turning, locking’ (STL) systems that, weighing in at 11,000 kg each, are the biggest STL systems that Dellner Brakes has ever built. Each of the carrier’s two propeller shafts is fitted with a custom-designed Dellner Brakes STL system that allows operators to stop, hold and securely lock each shaft independently, and to individually turn the shafts and giant 33 tonne propellers for maintenance and blade assembly.

Voith Completes First Major Marine Overhaul at New UK Facility

Voith Turbo, a manufacturer of a wide range of products for the marine industry, said it has completed its first major refurbishment project in a brand new U.K. facility. The complete overhaul of a 26-metric-ton Voith Schneider Propeller (VSP) has been carried out for Red Funnel, the Isle of Wight ferry company based in Southampton, at Voith’s Croydon workshop. The refurbishment follows Voith’s investment in specially designed jigs, fixtures, machinery and lifting equipment capable of handling Voith Schneider propellers, gearboxes and other ancillaries.

First Ship with IMO Tier III EIAPP Engines Launched

The launch of the L’Astrolabe, a 72 metre polar logistics vessel fitted with a complete Wärtsilä propulsion machinery package and Wärtsilä NOR (NOx Reducer) SCR (Selective Catalytic Reduction) exhaust gas cleaning systems for all the main engines, took place on July 12. This is the first vessel operating with the International Maritime Organisation’s IMO Tier III EIAPP (Engine International Air Pollution Prevention) certified Wärtsilä diesel engines. The ship was built by PIRIOU (France) for the French Southern and Antarctic Lands Administration.

CMV's Columbus Prepped for Summer Cruising

Damen Shiprepair Rotterdam (DSR), part of Damen Shiprepair & Conversion, said it has completed maintenance and repair works on the newest member of CMV’s fleet, the cruise ship Columbus. The full work scope was concluded within a tight timescale, thus ensuring that the vessel could sail to the London Cruise Terminal in Tilbury, U.K. in time for her naming ceremony and inaugural cruise. Several CMV vessels – the Astor, Marco Polo and the Magellan, for example – have made calls at various Damen repair yards in the past.

MHI and MHPS Jointly Develop Marine SOx Scrubber

Mitsubishi Heavy Industries, Ltd. (MHI) and Mitsubishi Hitachi Power Systems, Ltd. (MHPS) have jointly developed a Large-scale Rectangular Marine Scrubber that efficiently removes sulfur oxides (SOx) from the exhaust gases emitted by marine diesel engines. The scrubber was developed based on MHPS's flue-gas treatment technologies cultivated through desulfurization systems for thermal power plants, leveraging MHI's expertise in marine engineering. The adoption of a rectangular…

Schottel Gets Eight Ferry Newbuild Order for EcoPeller

Schottel has been selected to fit eight newly-built ferries with the new Schottel Rudder EcoPeller (SRE, EcoPeller) for two of Norway’s leading ferry lines. In close cooperation with the customers and Multi Maritime, the Norwegian ship designer in charge of the projects, the EcoPeller was chosen for three Fjord1 ferries with 2xSRE 340 CP each and five Torghatten ferries with 5x2 SRE 560 CP. “Our new ferry designs are the result of continuous efficiency optimization. Every potential efficiency increase and every optimization of the energy consumption in terms of design…

Wärtsilä Wins Contract for New CLdN RoRos

Wärtsilä said it has been awarded a contract to supply controllable pitch propellers and power take off / power take home (PTO/PTH) shaft generator systems for two new RoRo vessels being built at the Uljanik shipyard in Croatia. The ships have been ordered by the Luxembourg based operator, CLdN Ro-Ro SA. There is an option for an additional two vessels. Wärtsilä, which booked its orders in December 2016 and February 2017, will supply the vessels with its latest design, WCP G-hub, optimized for high power density.

WAAMpeller: World First Class-Approved 3D Printed Ship’s Propeller

A consortium of organizations are working toward a landmark achievement in the maritime sectors: creating the world's first class-approved 3D-printed ship's propeller. As many sectors of the shipbuilding industry suffer due to overcapacity, it is this type of innovative leap that will -- if successful -- separate the next generation of leaders in the sector. In the effort a cooperative consortium of Damen Shipyards Group, RAMLAB, Promarin, Autodesk and Bureau Veritas aim to develop the world’s first class approved 3D printed ship’s propeller, dubbed WAAMpeller.

New Briese Vessels Sport Schottel Propulsion

Briese Group contracted Groot Ship Design to deliver the design and basic engineering package for four multi-purpose vessels. Schottel performed enhanced CFD investigations to determine the optimal aftship configuration incorporating nozzle support and streamline body between rudder and hull. As a result, a streamlined CPP installation will enable a power reduction of 3.7 percent. The vessels feature an open and closed top design for variable cargo purposes. Each will measure 89.99 x 14.8 m with a difference in draft between 5.30 m (open) and 6.65 m (closed…
