Technical Presentation: Pioneering Air Lubrication for Shipping

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

DATE: TUESDAY, November 9th, 2021

TIME: 12:00 Eastern (9:00 Pacific, 13:00 Atlantic, 13:30 NFLD)

Technical Presentation by Silverstream Technologies – Pioneering Air Lubrication for Shipping

Abstract:

For over a decade, London-based Silverstream Technologies has pioneered air lubrication technologies within shipping. As clean technology leaders, they understand the relevance and importance of the solution to the IMO’s decarbonisation goals and passionately believe in the role of proven, innovative technologies in enabling a more sustainable shipping industry.

From a successful initial trial installation on the Danebrog Rederi tanker MT Amalienborg, sponsored by Shell, their technology has since been proven on many cruise ship installations. The solution is market-mature and has been adopted by industry leaders including MSC, Grimaldi, Carnival, and many others.

Uniquely within the market, their air lubrication technology harnesses fluid shearing – a natural phenomenon that occurs when two fluids of differing density move past each other – to create a microbubble carpet across the full flat bottom of the hull. This friction-reducing microbubble carpet maximises the emissions reduction and efficiency savings potential of the technology.

This presentation will provide an overview of Silverstream Technologies proprietary Air Lubrication System, the Silverstream® System. The natural phenomenon underpinning the technology, the Kelvin Helmholtz instability phenomenon will be introduced, and the main types of air lubrication concepts will be described. Following discussion on the application of the technology for various vessel types, several case studies will be referenced to provide details on the installation and performance of the system.

Technical Presentation: Improving ship efficiency through Becker Marine Systems Rudders and Mewis Duct

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

DATE: TUESDAY, October 12th, 2021

TIME: 12:00 Eastern (8:00 Pacific, 13:00 Atlantic, 13:30 NFLD)

Wartsila EEXI Engine Power Limitation Energy Efficiency Technology

Abstract:

Founded in 1946 by Willi Becker, Becker Marine Systems (BMS) has become the market leader for high- efficiency maneuvering systems and energy-saving devices for all types of vessels.

With the current introduction of the EEXI and CII in context, an overview of the Becker Marine Systems (BMS) relevant product portfolio is given.

Firstly, a brief insight into rudder theory and a comparison of different rudder types (in terms of efficiency vs. maneuverability) will be given, with a focus on twisted rudders with bulb.

Secondly, the energy-saving device Becker Mewis Duct® and its natural development, the Becker Mewis Duct® Twisted (formerly known as Becker Twisted Fin®), will be presented. With its flexible design approach, the Mewis Duct family works by creating a thrust, reducing the vessel drag by minimizing separation, and improving the propeller efficiency by introducing a pre-swirl. These effects combine to produce effective power reductions for all types of vessels.

With today’s emphasis on efficient performance, optimization of both rudders and ESDs rely heavily on the use of computational fluid dynamics (CFD) techniques. Use of CFD is now core to the design and development of BMS products, and some examples that illustrate how it is used for rudder and ESD optimization will be given.

Technical Presentation: Wartsila EEXI Engine Power Limitation Energy Efficiency Technology

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

DATE: TUESDAY, SEPTEMBER 14th, 2021

TIME: 12:00 Eastern (8:00 Pacific, 13:00 Atlantic, 13:30 NFLD)

Wartsila EEXI Engine Power Limitation Energy Efficiency Technology

Abstract: Synopsis: Planned to come into action in 2023 the proposed amendments to the MARPOL convention requires ships to combine a technical and an operational approach to reduce their carbon intensity. This is in line with the ambition of the Initial IMO GHG Strategy, which aims to reduce carbon intensity of international shipping by 40% by 2030, compared to 2008. The technical requirement to reduce carbon intensity, based on a new Energy Efficiency Existing Ship Index (EEXI); and the operational carbon intensity reduction requirements is based on a new operational carbon intensity indicator (CII).  The dual approach aims to address both technical (how the ship is retrofitted and equipped) and operational measures (how the ship operates). The attained Energy Efficiency Existing Ship Index (EEXI) is required to be calculated for every ship and in this webinar we will analyze the calculation and identify measures that will improve efficiency that will by extension improve the EEXI and CII.

St Lawrence Branch Donates to Mariner House in Montreal

On March 24, CIMarE St Lawrence Branch presented a $500.00 cheque to Mariners House in Montreal.  This donation supports the valuable work they provide seafarers which is especially required during the time of COVID 19.

Carolyn Osborne accepted the cheque on behalf of  Mariners House while Zack Papchristou ( Branch Treasurer and Chris King (Branch Chairman) made the presentation on behalf of the St Lawrence Branch.

The work done by Mariners House during COVID-19 is described by Carolyn below:

MARINERS’ HOUSE STILL OPERATING THROUGHOUT THE PANDEMIC

Since the start of the pandemic, Transport Canada has authorised seafarers to come ashore to either go straight to a centre for their use solely – such as Mariners’ House of Montreal – or to a pharmacy for essential items.  However, very few maritime companies permit their workers to disembark.  Nevertheless, a few have been able to come to Mariners’ House, which is still open five days a week and, as always, free transport is available to and from their ships.

 

While activities, including fundraising events, have been severely limited over the past year, Mariners’ House and the chaplains from their colleagues, the Ministry to Seafarers, have continued to operate.  Among the services offered to seafarers are SIM cards to access the internet on board vessels which do not provide this service for free, wired money transactions as well as personal purchases on behalf of the crew.

 

Seafarers have particularly suffered during COVID and Mariners’ House is relieved it has been able to ‘carry on’ assisting and raising the spirits of these essential workers.

Congratulations National Council Scholarship Recipient for 2020

Congratulations to Guillaume St-Yves, the recipient for the 2020 National Scholarship.  We are excited to support Mr. St-Yves’ education as a mechanical engineer at at l’École de Technologie Supérieure.  Below is the thank you note from Mr St-Yves describing his initiatives.

As a mechanical engineering student at l’École de Technologie Supérieure, I have always been motivated to learn and innovate. It’s for this reason that I quickly got involved within the university’s submarine scientific club, Omer.

 

It’s during our human-powered submarine projects that I was able to apply the knowledge and theories acquired in class and develop a passion for marine engineering. I aspire to continue to thrive and learn every day, from design adapted to underwater conditions to computed fluid analyses (CFD).

On our latest complete project, Omer 11, I’ve had the opportunity to do a lot of optimization. This was the first hybrid submarine in the world championship and it had the chance to display it’s innovation at the eISR and ISR (International Submarine Race). In fact, Omer 11 has two propulsion systems that can be interchange between races. The first system is a standard propeller and is equipped with precambered blades with an electrical variable pitch. It is also equipped with a non-prop system, similar to those used on sea kayaks. This propulsion called mirage has been completely redesigned in order to integrate a scotch yoke system and allow a circular motion to the pedals.

The current prototype, Omer 12, will be powered by a Voith-Schneider system. The design of the system is based on technologies already in the industry, but adapted to the power of two pilots. In addition to leading the team for almost two years, I had the opportunity to improve my knowledge of fluid dynamics. It has been useful in the design of an effective hull geometry and in my actual special project. It consists in optimizing the profile of our fins with biomimetism based on animal fins with bumps.

I would like to personally thank CIMarE for this recognition award! This contribution allows me and will allow me not to worry about my university tuition fees in order to put all my energy in the Omer project. I will understand even more about manufacturing methods and underwater conditions. I will be able to learn through the activities of CIMarE and pass on to my colleagues the possibilities offered by the organization.

These experiences and achievements within this branch of engineering inspire me to follow similar academic paths and opportunities.

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

The presenter:

Bodo Gospodnetic, Owner of Dominis

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.
