Technical Presentation: Decarbonizing Marine Shipping Clean Fuels for a Greener Future


DATE: THURSDAY, March 17th, 2022

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

Decarbonizing Marine Shipping Clean Fuels for a Greener


Bud Streeter will present some of the findings from Clear Seas Centre’s ongoing research on reducing GHGs from marine fuels.


Replacing the current fossil fuels used in ships with cleaner alternatives could provide solutions to the challenge of decarbonizing marine shipping. Ship fuels manufactured using renewable electricity and made purely from water and the gases found in the atmosphere, are being proposed. These include Hydrogen, Ammonia, Methanol and Methane. Clear Seas’ ongoing research on reducing GHGs from marine fuels provides some valuable insights.


Bud Streeter,

Bud Streeter has spent over 50 years in the marine business.  He is a graduate of the Canadian Coast Guard College and holds a First Class Engineering Certificate of Competency.  He has served as an Instructor at the Canadian Coast Guard College, a Marine Inspector, Examiner and Manager with Marine Safety and as a Technical Director and Executive Officer with Marine Atlantic.  He served as Director General Marine Safety during which time he was the head of Delegation to many IMO meetings. His most recent fulltime employment was with Lloyd’s Register where he held executive positions in the Americas.  He retired from full time employment at the end of 2017.

He has served as a Board Member for Meridian Shipping Limited and for many Lloyd’s Register entities.  He was appointed to the Canadian Advisory Council on National Security and served as a marine security advisor between 2005 and 2009.

Bud is a member of the board and Past Chair of the Clear Seas Centre for Responsible Marine Shipping, an independent research centre that promotes safe and sustainable marine shipping in Canada. He also serves as the Honorary President of the Canadian Institute of Marine Engineering (CIMarE).  He is a recipient of the CIMarE’s Medal of Excellence.

Technical Presentation Duel Fuel Technologies for 2 Stroke MAN B&W Engines



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

Technical Presentation by MAN Energy Solutions – Duel Fuel Technologies


This presentation will cover the state-of-the-art technology in the design of Dual fuel MAN B&W 2 stroke engines.  Special attention to the Methanol engine and the ongoing development of an Ammonia burning engine.

Today MAN B&W engines can operate on different fuels that are considered to be future fuels for the Marine Industry. A diesel technology based on the IC diesel engine principle makes it possible to keep the same high efficiency, up to 55%, and the same high power output.

The two stroke engines are the most used prime mover in ocean going ships today. In 2021, 30% of the contracted output from 2 stroke engines for ships were by Dual Fuel. The MAN B&W engines have a power range from 3 to 83 MW per engine and are based on a modular concept which makes it possible to retrofit the ME-C engine to operate with LNG, Methanol, LPG, Ethane and in near future Ammonia.

The different fuels mentioned have different characteristics which provide different challenges in the design process. The fuel injection components are dependent on the right choice of the materials and tailor made elastomers. For fuels without lubricating ability, such as Methanol, a special design of the fuel injection booster pumps and injection valves has been invented.

A complicated part of the design is to find the right injection pressure to the engine and into the combustion chambers.  The fuel gas supply system is therefore optimized individually. Pressure and amount of the dual fuel to be delivered to the engine is based on the fuel specifics.

The engines still have to comply with IMO Annex Tier II and III and we also need to ensure that other harmful emissions in the exhaust gas are under control.  The Ammonia engine has to be NOx compliant and the amount of Ammonia slip has to be minimized down to an insignificant level.  Testing of this engine will begin this year.

Furthermore, N2O levels need to be 0 ppm as they are very harmful to the GHG. “Regulation for maximum level is not in place yet.”

In this presentation, we would like to introduce our different dual fuel technologies and the consideration of the safety / HAZID / HAZOP, reliability and availability that underlies the engine design.

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.
