Technical Presentation: An Overseas Perspective


DATE: Thursday, November 18th, 2021

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

An Overseas Perspective


Daniel Sanchez, a graduate marine engineer form the Technical University of Madrid will give a presentation on the kind of refit/repair/modification which an Offshore Supply Vessel (or it’s cousins in the oil & gas fleet) go through when being put back into service after a lengthy layup (warm or cold).

He oversaw a number of such mechanical and structural projects while working at a repair yard in the Canary Islands prior to coming to Canada.

As the shipping world urgently reactivates itself across almost all trading routes, this type of knowledge becomes more and more important.

Technical Presentation: Investigating an Occurrence on a Vessel


DATE: THURSDAY, November 18th, 2021

TIME: 12:15 Atlantic (8:15 Pacific, 11:15 Eastern, 12:45 NFLD)

Investigating an Occurrence on a Vessel


At some time in our sea going or shore side careers we are going to encounter a situation where damage is sustained to a Vessel, its equipment or it’s crew.  How do we document and report the findings of the Investigation so that lessons can be learned.


The primary reason for an investigation is to identify the causes(s) of an occurrence so as to initiate action(s) to prevent similar occurrences.

This is achieved by determining what happened, how and why it happened so that modifications can be made to procedures or equipment that will improve the safety of the Vessel operations.

Accurate and thorough reporting of all occurrences is required to enable lessons to be learnt which may prevent future occurrences.

How to document the occurrence, how to interview witnesses, how to prepare a report are all things that we shall look at in this presentation.

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.

Technical Presentation: Pioneering Air Lubrication for Shipping


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


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.

Coping with CoP26: Climate change and the global shipping industry in 2021


Jeffrey Smith presents a survey of climate change developments in the global and Canadian shipping industries, in the context of the UNFCCC Conference of the Parties next month.


The need to reckon with and reduce greenhouse gas emissions has been apparent to the shipping industry for almost 30 years, even as the overall size of the global trade fleet has steadily increased. The presentation first addresses the nature and trend in emissions. The successes of air pollution control of nitrogen and sulphur compounds are recalled. The treaty arrangements created by states in the International Maritime Organization are considered. Current regulatory measures and the notable commitment of IMO states in 2018 to extensive reductions are explored. The presentation concludes with an evaluation of requirements to come after CoP 26 and the trend of individual states to move to economic and direct regulation of emissions.

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


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


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.

Sept 16 VI Branch Meeting

Vancouver Island Branch Meeting – In Person Harbour Road Yard Tour

Thursday, 16 September is our first in-person meeting in close to two years, and it will be a good one!

Point Hope Maritime is courteously hosting VI branch’s September meeting with a tour of their Harbour Road Yard in the upper harbor.

We’ll assemble inside the gate nearest the Johnson St.  Bridge (Old Blue….) for an 1830 tour start. 

Parking will be inside the yard gate to the right, one of us will be there to guide you.


Cyclists coming off the bridge ramp at the head of the yard’s driveway can be a real hazard! They are coasting, fast, and often don’t realize that cars are transiting their bike lanes. Be very alert and cautious as you make the turn into the yard.

AND A REMINDER;   Dress for the weather.   We’ll be walking outside. Gloves may be useful, sturdy walking shoes are suggested (no open toes or heels!).  Bring a mask so that if we go inside we can be compliant with health directives.

For those of you not familiar with the yard, it is a full-service yard, with a full machine shop, assembly hall, welding shop, electrical shop, and a sophisticated painting prep and application crew.  Vessels are hauled on a 1200 ton marine railway to a turntable, then the vessels are shunted onto spur tracks where the work is done. They have a fully compliant waste water treatment system, and use advanced hoarding and noise abatement systems to minimize their impact on nearby neighbourhoods.

Sam Johnson, the Production Technical Manager, will guide the tour.  He will also describe some of their future plans —it’s quite a vision.

We may be able to get aboard a vessel(s) on the hard, depending on what vessels are hauled that evening.



Bill Wallace, VI Branch Comms, for the Executive Committee
