Technical Presentation by DOMINIS – Impact of Manufacturing Tolerances on Propeller Performance

C.I.MAR.E.    ST. LAWRENCE BRANCH INVITES YOU TO JOIN THEM FOR AN INFORMATIVE WEBINAR

DATE: TUESDAY, March 9th

TIME: 12:00 pm EST (9:00 am PACIFIC, 1:00 pm ATLANTIC, 1:30 pm NFLD)

Impact of Manufacturing Tolerances on Propeller Performance

Background:

Anthropogenic underwater radiated noise is now being recognized as a worldwide problem. For ship speeds greater than about 15 knots, propeller cavitation is the predominant source of propeller-generated underwater noise and vibrations.  Cavitation not only influences propeller-induced pressure fluctuations on ship hulls and increases noise levels in ships, but it also impacts the ocean environment with
underwater noise pollution. Many studies are investigating the effects of propeller design parameters on propeller performance and cavitation. However, there is a critical gap in understanding the impact of manufacturing tolerances on propeller cavitation and to some extent on propulsive performance. This project addresses that gap in knowledge. The primary tools in the investigation is Computational Fluid Dynamics (CFD) methods supported by model experiments to validate their results.

Project Overview:

The project compares “as-built” propeller blade sections with their ideal “asdesigned” counterpart to elucidate the effects of manufacturing defects on cavitation and propulsive performance. The study is investigating the effect of  sharp-edged flat regions near the LE, which are within the tolerances of ISO 484 class S. The project work is organised in three investigations incorporating both CFD simulations and experimental support as follows:

  • Investigation 1: 2D foil section investigation in rectilinear flow
  • Investigation 2: 3D wing planform investigation in rectilinear flow
  • Investigation 3: 3D full propeller (rotating)

Partners:

  1. Dominis Engineering: Project lead, managing experimental program manufacturing of models and reporting
  2. Memorial University (MUN): CFD modelling
  3. DRDC – Atlantic: CFD modelling

Technical Presentation by WÄRTSILÄ VOYAGE DIVISION – Automated Sailing and Docking Technology

C.I.MAR.E.    ST. LAWRENCE BRANCH INVITES YOU TO JOIN THEM FOR AN INFORMATIVE WEBINAR

DATE: TUESDAY, February 9th

TIME: 12:00 pm EST (9:00 am PACIFIC, 1:00 pm ATLANTIC, 1:30 pm NFLD)

Automated Sailing and Docking Technology Today

Abstract:

Wärtsilä’s Voyage division installed its first commercial SmartMove Suite navigation system aboard the 42-year-old laker American Courage in March 2020. The self-discharging vessel is 630 feet (192 m) long and operates on Ohio’s winding Cuyahoga River. This waterway can be very congested, and Wärtsilä says that it is easily the most challenging route for any vessel using automated sailing and docking technology today.

“Advanced decision support systems, such as Wärtsilä’s SmartMove, bring value because they can automate the repetitive tasks, such as docking on repeated itineraries,” said Wärtsilä Voyage’s John J. Marshall. “This is not about going captain-free, rather, enhancing the capabilities of onboard crew as they traverse shuttle routes, congested or restricted areas.

The version of the system installed aboard American Courage uses the surrounding environment for vessel positioning, making it ship-based rather than on shore, according to Pierre Pelletreau of Rand-ASC Holdings, American Steamship’s parent company. It is designed to meet the firm’s requirement for a position margin of less than two meters.

Vancouver Island Branch Meeting and Technical Presentation

 

Thursday’s presenter will be Klaus Kreye from BC Hydro.

He’ll be speaking about power supply to Vancouver Island and particularly to the challenges of providing cold-ironing capability at the Ogden Point piers.

He’ll welcome all questions, not just particular ones to the topic above, recognizing that his expertise and ours overlaps in the field of shorepower requirements of large cruise ships. and there are a wide range of interesting electrical issues in play on our Island.

The meeting will use CIMarE’s GoToMeeting software as its platform

It’s an easy platform to use  (trust me on this……….I’ve had no problems using it, and I’m no computer whiz……)

The site will open at 1900; the first 30 minutes are the equivalent of the friendly conversations prior to our in-person meetings, and can also provide time to salt down minor procedural glitches.  The presentation will start at 1930 from your favorite browser, log into the members only area and view the event to get the GoTo Meeting Link.

Our Web Meeting Coordinator, Brian Merz, will be onsite to support us if there is a hiccup, and can be reached by phone at 236-562-4738 once the site opens.

This new media platform will widen the scope of future potential presentations and it will enable us to stay in contact with one another both visually and audibly.

Our first few virtual Branch meetings  have been excellent.

I hope that all who can will partake of this opportunity to be part of a significant step forward in the Vancouver Island Branch’s future.

Technical Presentation: Schoenrock Hydraulik Marine Systems – Access in Motion

C.I.MAR.E.    ST. LAWRENCE BRANCH INVITES YOU TO JOIN THEM FOR AN INFORMATIVE WEBINAR

DATE: TUESDAY, January 12th 

TIME: 12:00 pm EST (9:00 am PACIFIC, 1:00 pm ATLANTIC, 1:30 pm NFLD)

Schoenrock Hydraulik Marine Systems – Access in Motion

Abstract: Water ingress caused by a damage of the ships hull is next to fire the second main threat for the life of crew members of a ship and the vessel itself. To keep the vessel afloat and control the effects of such an ingress is therefore a vital task of ship designer, crew members and finally supplier of equipment against this impact. Integrity stability calculation and damage control can save the vessel against sinking and so the crew of getting into a serious, probably lethal situation. Schoenrock Hydraulik Marine Systems is with their products part of the solution to keep damaged vessels at the water surface and to secure it against a worst-case scenario.

The presentation should give a view to the state-of-the-art technology of modern watertight door systems as well as watertight shell doors and hatches. The focus will be at the sliding door solutions, available drive concepts and actual developments how to get the doors tight up to 50m water column. Finally, some special designs like combined A60 fire rated watertight doors and shock-approved door solutions will be shown.

The presenter:

Dr. Ing. Volker Behrens, Managing Director, Schoenrock Hydraulik Marine Systems

Dr.-Ing. Volker Behrens is working since more than 12 years for Schoenrock. Staying 12 years in the German Navy as a technical and damage control officer and a later position as sales manager for air-conditioning and fire-fighting systems are a perfect background to understand not only the technology of watertight doors and hatches, but also consider the whole aspects of protecting vessels against damages with water ingress.
