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:


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.

Historical Events




TIME: 19:00 Pacific (22:00 Eastern, 23:00 Atlantic, 23:30 NFLD)


This coming Thursday, the 19th of March, Ryan Nicoll will give a presentation on how the mooring systems of deep-ocean oceanographic buoys are developed, along with a comparison of predicted vs. actual mooring loads. Oceanographic moorings are critical to our collective ability to measure and understand oceanographic processes. The moorings locate buoys in all water depths, and must survive the effects of wind, currents, and waves. Development and deployment of these buoys is critically dependent on their mooring systems.

The mooring systems, in turn, are site-specific to the buoys’ location, and the engineering behind the mooring systems are a specialty of DSA Ocean, which Ryan founded.

A presentation by the Future Technology Panel of the International Maritime Rescue Federation

For thousands of years humankind has had a beneficial relationship with the world’s oceans, lakes, and rivers, for food, transport, and leisure. However, this relationship has not been without cost, the risk of injury and death has always been present, over 300,000 people drown annually.

For the past two centuries rescue organizations have responded to those in distress on the water. Over one hundred of these maritime rescue organizations from 54 countries worldwide are members of the International Maritime Rescue Federation (IMRF), an NGO at IMO. The IMRF facilitates the sharing of experience, expertise, and knowledge among its member organizations in order to save lives, and to protect rescue personnel worldwide.

The Future Technology Panel (FTP) of the IMRF is a group of member organizations which meet to share information and assist each other with the evaluation and implementation of new technologies. The projects cover many areas, large and small, such as the application of Remotely Piloted Air and Marine Systems, autonomous systems, electronic alerting and locating technologies, small craft navigation, crew safety and health.

This presentation outlines many of these technologies, the processes to identify and evaluate these technologies, the possible benefits, and pitfalls, the impact on the public safety, and the impact on the safety of rescue personnel. The FTP members evaluate technologies which have near term application, and those which look further into the future.

This presentation will be of interest to anyone who is concerned with Maritime Safety. Contributors: Search & Rescue Organizations & related firms in Australia, Canada, Germany, Ireland, Norway, South Africa, Sweden, & the United Kingdom.

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


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


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)

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


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


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.
