Short Courses Supporting Canada’s Quiet Vessel Initiative and Marine Industry

In partnership with and with the support of Transport Canada, CISMaRT is to provide three short courses, “familiarization”, “conversion” and “advanced” courses, to support the marine industry on the reduction of underwater vessel noise. The three courses, each with submodules, are at the post-secondary level for marine engineers and other functional specialists, such as policy officers, to increase the understanding of underwater noise caused by ships and its impacts on the marine environment.

The first familiarization short course, Introduction to Ships and the Shipping World, is designed for early-career naval architects and engineers, policy officers and non-technical personnel. It will be delivered through Brightspace, an online learning management system, from October 24 to November 2, 2023.

Details on the first short course and the registration deadline can be found below.

Download the poster and have a glance at the schedule and modules for the first short course.

  • Early career naval architects, engineers and policy officers typically have excellent technical knowledge and look forward to applying them when they join the workforce.  However, generally not included in their education is an understanding of the wider maritime world. Without this knowledge they lack the context for their work.  This “familiarization” course is designed for such naval architects, engineers and policy officers, and the objective of which is to provide this context.  It should be noted that while the course is directed at early career technical graduates, non-technical personnel could find it potentially useful as an introduction to the world of ships.

    This short course provides a comprehensive introduction to the maritime world with a focus on ships. This is accomplished by summarizing the stages in the lifecycle of ships starting at the design stage through construction and finally to operations and maintenance. The regulatory environment in which these are undertaken is also described.

    This course, consisting of six 3-hour modules, will be delivered through Brightspace, an online learning management system.

    Each module is followed by an online quiz. After the successful completion of six quizzes by November 10, 2023, participants will receive their certificates through the Brightspace system.

    Time: 12:00 – 15:30 (EDT), including a half-hour break

    Dates: October 24, 25, 26 and 27, November 1 and 2, 2023

    Registration fee – $500 CAD/person

    Registration deadline – October 10, 2023

  • Module A:  Types of Ships and Their Functions and Features

    This module will provide an introduction to the design of vessels, including ships, boats and offshore structures with an emphasis on vessels in operation in Canada.  

    The first part of the lecture will introduce the basic parameters used in naval architecture to characterize ship designs.  Topics will include both dimensional (length overall, draft, depth, etc.) and non-dimensional parameters (block coefficient, prismatic coefficients and ratios such as length to beam) and how various parameters vary based on the service type of the vessel.

    The second part will discuss vessel types, including but not limited to icebreakers, containerships, large and small fishing vessels, lakers, ferries and floating offshore structures.  A case study will be presented on how regulatory frameworks influence vessel design. 

    Module B:  Regulatory Environment I – History and Current Operations

    This module will provide a brief introduction to the history of marine regulations, from medieval load lines to the development of the International Marine Organization (IMO) and the International Association of Classification Societies (IACS). 

    The module will explain the current system of marine regulation, including international and national regulators and flag and port state certification inspection regimes. Materials will cover the roles of classification societies and other standards organizations, and how insurance is applied to vessels themselves and to their cargoes.

    Some of the key regulatory instruments will be outlined, including the SOLAS, MARPOL, Load Line and ISM Conventions. Canada’s specific approach to marine regulations will be outlined, noting how vessels outside the IMO framework are handled and noting the scope of various Acts that apply to Canadian vessels and their operations.

    Module C:  Regulatory Environment II – Future Development and Challenges

    This module will continue from Module B to review the initiatives now underway in the regulatory world and their implications for stakeholders.

    Two main themes discussed will be digitization and environmental protection. Rapid progress in information technology is providing opportunities to operate with reduced or even zero human intervention, and to replace scheduled inspections and certifications with processes based on continuous monitoring and other types of “big data” analyses. Challenges include cybersecurity and effective monitoring and audit.

    Environmentally, the critical need to decarbonize marine transportation is generating new regulations and an urgent need to update many existing regulations and standards to handle non-traditional fuels and their supply chains. Other types of environmental protection include vessel quietening, the ongoing need to control invasive species, etc.

    The module will address both the international and the Canadian contexts, and specific domestic challenges.

    Module D:  Shipbuilding

    This module will step through the end-to-end shipbuilding process. Starting from establishing owners’ requirements and the preliminary, concept, and functional design cycles, the module will highlight the critical decisions and design elements to stabilize early in order to minimize late-stage changes.  The detail production design phases will also be introduced to explain how the total ship design is broken down into producible assemblies, modules, units, and blocks that can be planned in detail for production.  This will describe the detailed planning functions and demonstrate the importance of an integrated master schedule.

    Each stage of ship construction will be introduced, starting from early steel procurement and steel preparation into minor, complex and unit assembly.   Unit outfitting stages will be shown next, highlighting the objectives of maximizing outfitting (pipe, electrical, HVAC, etc.) efficiency at the earliest possible stages of construction. Later stages of block consolidation, paint, mega block erections, and mega block joins will also be highlighted. 

    Finally, this module will highlight the launch process and outline the test and trial activities which ultimately lead to commissioning and delivery to the customer.  Additional topics throughout the lecture will include material specifications/requirements, welding processes, accuracy control, corrosion prevention, and anti-fouling.

    Module E:  Operation of Ships

    This module will briefly introduce course attendees to some of the onboard and operational aspects of the maritime industry.  It is intended to provide course attendees who have no onboard experience with an understanding of how shipboard life differs from life in shore-based maritime industry professions.  The lecture will cover three broad subject areas: shipboard life, voyage planning and port operations.  

    In discussing shipboard life the lecture will outline who is onboard and what they do.  The organization typically found on ships is described.  Those on board are the officers and the crew.  These are discussed together with the departmental organization (deck, engine and hotel/supply).  Also discussed are the temporary specialists, external or temporary.  This is exemplified by riders, pilots and ice navigators.  Issues associated with time away from home are discussed.  These include the impact on personal, social and family wellbeing, and also related fatigue issues.

    The important subject of voyage planning will be discussed.  This part opens with a brief overview of how voyages are planned and executed, and the associated administrative burden.  Also discussed are ice operations and the differences experienced between operations in the Arctic and the Southern Ocean.  The role of the IMO Polar Code and Ice Navigator training are introduced.

    The final broad area of ship operations discussed is port operations.  The key aspects of cargo handling are introduced including interactions with agents, cargo planning and dealing with port requirements.  The importance of being aware of differences in cargo requirements for different types of trade such as passenger, bulk, liquid, breakbulk, and containers is outlined.  A similar treatment is presented for specialized ships such as self-unloaders, geared ships; product, crude, chemical, gas tankers and others.  Bunker operations are also discussed.  Also summarized are the interactions with agencies beyond those concerned directly with ship operations, including agents, auditors, and inspectors leading to administrative overburden which contributes to fatigue.

    Module F:  Maintenance of Ships

    Ship maintenance concerns the management and engineering activity that is required to keep ships, and the systems in them, functional and safe.  Maintenance is a cradle-to-grave activity and gets more intensive as the ship ages.  This module opens with a discussion of the relevant general aspects by summarizing the importance of maintenance, and the business and management aspects of maintenance.  The organizations relevant to this activity are introduced. 

    This is followed by a summary of the types of maintenance methodologies that have developed over the decades focusing on those used on ships.  The hull structure and all the systems contained within are all subject to wear and tear.  The process of deterioration that hull structure and other systems suffer is described and illustrative examples are provided.  The main preventive measures taken to avoid deterioration during design, construction and operation are also outlined.  Emphasis is given to the hull structure as the part of the ship that most maintenance resources are applied to during the lifetime of the vessel.   Repair measures necessary to maintain strength are introduced.

    Surveys are an important systematic task undertaken to determine the state of the vessel at a given time; this is summarized.  The important subject of human factors is briefly surveyed.    The module concludes with a discussion of trends that are likely to impact the way ships are maintained.  Some of the future challenges are also noted.

The course lectures provide high-level coverage of technical topics normally covered in a naval architecture and marine engineering degree program. It will be delivered through Brightspace, an online learning management system, from February 6 to 28, 2024.

Details on the second short course and the registration deadline can be found below.

Poster for the Applied Naval Architecture short course

  • This short course is designed for engineers with a degree in an engineering discipline other than naval architecture and/or marine engineering.  While this category of engineers will have an understanding of fundamental aspects of engineering, knowledge of application to ships and marine environments will be lacking.  This “conversion” course is to introduce these engineers to selected aspects of naval architecture and marine engineering.  The focus will be more on applications rather than theory.  This will allow them to apply their knowledge and training to the problems in the marine environment more effectively, especially considering the reduction of underwater vessel noise by ships.

    This course, consisting of eight 3-hour modules, will be delivered through Brightspace, an online learning management system.

    Each module is followed by an online quiz. After the successful completion of eight quizzes (three attempts and a 70% passing grade for each quiz) and a survey by March 31, 2024, participants will receive their certificates through the Brightspace system.

    • Time: 12:30 – 16:00 (EDT), including a half-hour break

    • Dates: February 6, 7, 8, 12, 14, 20, 27 and 28, 2024

    Ship Resistance

    This module will introduce course attendees to the key elements of ship resistance. This includes how ship resistance is composed of wave-making drag and surface resistance. Procedures to predict these resistance components will be introduced and highlighted through practical examples. Methods to reduce the ship resistance will also be featured. The course is intended to provide an understanding of how Naval Architects must estimate ship resistance in order to accurately predict operational speeds and propulsion requirements. The lecture will cover common questions including:

    • How does fluid flow around the hull create drag?

    • What is Froude’s Law and why is it important in the prediction of ship drag?

    • What are some of the key factors that influence hull resistance?

    • How is ship resistance predicted using model testing and/or computational fluid dynamics?

    • What techniques can be used to reduce hull resistance?

    Marine Environment

    The marine environment that ships and other marine systems operate in is often harsh and demanding.  Those responsible for the design and operation of such systems need, therefore, to have a good understanding of relevant environmental phenomena.  These phenomena are often complex and difficult to characterize.  Designers and operators from the marine community have developed various simplified methods and tools to support the maritime community for both design and operational tasks.  These are outlined, as is the data required for these tasks.  The sources for the data are summarized. The course will present the following topics selected to provide a broad introduction to the marine environment:

    • Global climate system

    • Wind

    • Waves

    • Currents

    • Ice

    • Underwater sound

    Also discussed are trends such as climate change which may require modification in the treatment of relevant design variables. The lecture will also include a few simple examples and case studies relevant to aspects of the marine environment.

    Ship Design Process

    This module provides an overview of the ship design process. The course shows how all aspects of naval architecture and marine engineering are combined together to create a ship design that is best suited for it’s mission requirements. The course covers:

    • Phases of the ship design process – concept, preliminary, contract & detailed design

    • Defining requirements for the main features of the ship – mission, function, performance and economics

    • The design spiral and system-based ship design

    • Preliminary ship design methods and software

    Hydrostatics and Ship Stability

    This module introduces the key topics related to stability of small and large ships:

    • Discussion of equilibrium of ships in still water, including a case study of a small tugboat.

    • Hydrostatic curves and stability at small and large angles of heel, including a case study of a self-righting fire and rescue boat.

    • Impact on vessel loading and stability, including a case study of an anchor handling / offshore tug.

    • Vessel size and regulatory impacts on stability requirements.

    • Dynamic stability, including a case study of an escort/ship handling tug.

    • Damage stability, including a case study of a large science vessel.

    • Final case study of a small fishing vessel demonstrating the impacts of various effects on vessel stability.

    Ship Materials and Structures

    The focus of this module is on ship structures. We will explain why they are mainly built from steel and why they look as they do. The pros and cons of materials like aluminum and composites will be described. Ship structural design is tightly controlled by the structural requirements in Classification Society rules. The reasons for this as well as some of the basic principles inherent in the rules will be discussed. The question of the longitudinal strength of ships is a special focus because of the critical importance of longitudinal strength to ship safety. We will take both a first-principle and a rule-based look at this issue. Following that we will discuss the strength of plating and framing. We will wrap up with a short discussion of a variety of other topics that ship structural specialists must also consider.

    Ship Electrical Systems

    The course module is an introduction to electrical and control systems from a marine classification and regulatory perspective. The harsh marine environment, prescriptive statutory requirements, environmental protection implications and solitary nature of ships present themselves with inherent engineering challenges. As all sectors of the industry strive to become more environmentally conscious the marine world is adapting by driving changes of the ships of yesteryear to current challenges of decarbonization, reduction of staffing and autonomous capability by introducing complex electrotechnical designs. The course module will introduce concepts focusing on electrotechnical matters such as:

    • International standards and Regulations including aspects of SOLAS, IMO and IACS and flag administration such as Transport Canada

    • Standard electrical ship design concepts in terms of redundancies, survivability, emergency principles

    • Modern ship design with regards to electrification and energy storage

    Maneuvering and Seakeeping

    This module describes seakeeping and maneuvering, including underlying physics, analysis methods, and design considerations.  Lessons learned are provided from a variety of sources, including numerical simulations, model tests, sea trials, and operational experience. 

    • Ocean waves; 

    • Seakeeping, including prediction of ship motions and application of motion predictions; 

    • Maneuvering in calm water; 

    • Maneuvering in waves; 

    • Complex scenarios, including replenishment at sea, and launch and recovery.

    Ship Propulsion

    This module describes some common ways energy is converted into practical propulsion devices for ships. The module starts with a review of different propulsive devices, compares their relative performance, and then explains why screw propellers have become by far and away the most common device. Propellers are usually placed at the aft end of the ship, and as a result, the flow into the propeller is affected by the ship in front. Understanding the interaction between the main engine, the hull, and the propeller, as well as the presence of cavitation in the flow are key parts of managing the noise generated by ships. The module will cover

    • Types of propulsion device (screw propellers, podded propellers, water jets, vertical axis propellers and paddle wheels)

    • Theory of screw propellers

    • Selecting the main mechanical components of ship propulsion system (engine, drive shaft, bearings, etc.)

    • Hydrodynamic interactions between the ship and the propeller

    • Practical approaches for designing screw propellers. 

    • Cavitation 

    • Fuel saving devices.

  • Ship Underwater Radiated Noise – Course Modules

    Fundamentals of Underwater Radiated Noise

    This module introduces fundamentals of ship noise. After an introduction to the relevance of ship noise in ship design and the primary sources of noise on ships, we will focus on key concepts of acoustics, including a qualitative introduction to acoustic wave phenomena, such as wavefronts, interference, reflection, scattering, diffraction, etc., and an overview of the main parameters used to quantify sound, as sound pressure levels, sound intensity levels, and energy density levels. We will then focus on sound propagation in water to understand how sound waves propagate in the ocean and how the environment alters sound propagation and shapes the ocean soundscape. Finally, we will provide an overview of the main effects of ship noise on marine life and of national and international regulatory bodies’ efforts to develop new standards to mitigate noise exposures of taxa.

    Propeller and Appendage Noise

    This module describes the mechanisms of underwater radiated noise resulting from the ship’s propeller and other hull appendages. Typically, a cavitating propeller is the dominant noise source on a ship across most frequency bands, but a non-cavitating propeller and the other underwater appendages (bulbous bow, bilge keels, A-brackets, rudders, etc.) can also contribute to the overall ship noise. The module will discuss the physical mechanisms behind the noise, the characteristics of the noise generated, and the changes in the noise with ship speed. 

    • Non-cavitating propeller noise

    • Propeller cavitation

    • Ship appendages and noise

    • Bow thrusters

    • Modelling hydrodynamic noise

    • Noise transmission in the sea

    Sources and Transmission of Vibrations

    This module outlines the basics of ship vibrations and noise resulting from onboard machinery. While the propeller is often the dominant source of underwater radiated noise, the onboard machinery is also typically a significant contributor to the overall ship’s underwater radiated noise. In particular, the main engines, diesel alternators, and gearboxes are significant noise sources, but all onboard machinery contributes to some extent. The noise is transmitted through direct contact with the hull as well as secondary fluid-borne and air-borne paths.

    • Basic concepts of mechanical vibrations – mass, stiffness and damping

    • Free, forced and transient vibrations

    • Sources of vibrations in ships – main engines, generators, pumps, auxiliary machinery

    • Transmission of structure-borne noise in ships

    • Secondary noise paths

    • Transmission of noise into surrounding fluid

    Underwater Radiated Noise Measurements

    This module will introduce attendees to the key elements of underwater radiated noise (URN) measurements of vessels at sea.  There will be a brief introduction to general acoustics and underwater sound metrics (decibels) to ensure all attendees have the same basic understanding of the units of measure to be discussed throughout the course.  The program will provide basics on URN instrumentation; hydrophones, frequency domain data collection systems such as FFT and octave band analysis systems.  The arrangements of at-sea measurement systems will be discussed along with example ship URN sound profiles.  Finally, the course will discuss relevant standards for the measurement of vessel URN from ANSI, ASA, ISO and the Class Societies.

    Underwater Radiated Noise Modelling and Prediction

    This session will dive into the different techniques currently available to predict and assess underwater noise radiated by ships including:

    • Empirical methodologies

    • Open-source codes for underwater sound propagation

    • Propeller noise prediction techniques

    • Dynamic stiffness assessment of foundations and the impact to underwater noise

    • Finite element (FE) modelling combined with boundary element methods (BEMs) for hull radiation prediction

    • Statistical energy analysis (SEA) for hull radiation

    The session will focus on the theory behind the different techniques, it is not specific to any particular tool where FE, SEA, BEM concepts were implemented. Some rules of thumb will be discussed when it comes to shipping design. Moreover, the session will touch upon the accuracy of each technique and its validation.

    Underwater Radiated Noise Reduction Strategies

    This module will introduce attendees to Underwater Radiated Noise (URN) reduction strategies.  There will be a brief introduction to general acoustics and underwater sound metrics (decibels) to ensure all attendees have the same basic understanding of the units of measure to be discussed throughout the course.  A background on the transmission of shipboard sound and vibration into the water will also be provided, as the different transmission paths need to be mitigated differently.  The focus of this module will be the principal methods for URN reduction for each of the sources and paths.  Treatments used outside the hull will be discussed, including flow improvements, quiet propellers and air bubble systems.  Engineered treatments used within the hull will be discussed, including vibration isolation mounts, equipment enclosures, hull damping, and plating insulation.  Operational measures for the reduction of URN will also be addressed.  Example treatments and outcomes will be given.
