Senior Thesis: Development of a Method for Comparison of Shipboard Power Transmission Models
By Spencer Margosian ’23 and Tori Kim ’23
It is the beauty of research that in pursuit of solving even a seemingly simple problem, one will inevitably discover far more new problems to solve than they will answers to publish. Looking back on the past year, the best example of this was when our electrical engineering thesis was almost completely derailed for well over a month, by a problem fundamental to naval architecture. In this article, we would like to discuss how we came across this problem, how we solved it, and how this detour in our work taught us a fundamental principle of research. The minimum viable background for discussion of our thesis takes about four sentences. For large vessels, medium-voltage alternating current is usually used to transmit electrical power.
An emerging technology, medium-voltage direct current power transmission, is poised to be ready for commercial application approximately within the next decade. Because MVDC is a new technology, it is not well known to marine engineers and will likely be underutilized if it remains unknown.
Spencer Margosian ’23 accepting his award during SNAME’s Student Paper night.
Our thesis sets out to identify in simple terms whether MVAC or MVDC is the better system model for a given application so that a marine engineer does not need to do so from first principles. The first time we attempted to compare the two
system models directly, we created two calculation methods which modeled steady-state operation of a given vessel. When we tested the two methods with a computer script, the answers they returned looked like they made sense when considered one-at-a-time. Upon examining the entire set of cases, however, we realized that not a single case actually implied that DC was preferable to AC—not even those which we were positive would be.
The discovery of this fault effectively stopped us in our tracks, not knowing what we had done wrong or how we might fix our program to account for such error. To solve this problem, we would have to embrace a core principle of research: that setting out to solve a problem in one field will often result in encountering new problems in unrelated ones. Following the failure of the original analysis, we would come to realize that using a steady-state analysis failed to account for the biggest advantage of MVDC systems, which is their high efficiency in loads which vary over time. This meant that to properly compare the two system models, it would be necessary to model them as dynamic systems and not constant signals.
“We are immensely grateful to Webb for preparing us not only with the education in marine engineering necessary to understand marine electrical engineering, but also for providing us the naval architecture background that we needed to solve our resistance problem. Despite neither of us identifying as naval architects at heart, the Webb education prepared us to tackle every problem our research threw at us.”
We had found a new problem to solve—how does a ship’s electrical load change throughout a voyage?—and despite our original research being one of theoretical electrical engineering, the answer to our new question relied almost exclusively on our understanding of naval architecture.
The biggest load experienced by a ship at sea is naturally the energy required to propel the vessel through the water. As a ship sails through waves, the resistance imparted on the vessel varies constantly, changing the propulsion power. This phenomenon, called added wave resistance, cannot be easily predicted using statistics—in fact, it is not analytically possible to do so. However, by algebraically manipulating a well-documented standardized wave spectrum, we were able to closely approximate what the added wave resistance spectrum would look like and solve our original problem of characterizing how resistance varies over a voyage.

First-Generation College Graduate to Finance Chair
By Paulo Almeida ’95
Background
I’m a first-generation college graduate and first-generation American from Danbury, CT, which unsurprisingly was recently rated the most diverse (ethnic, religious and socio-economic) city in New England. My parents grew up 15 miles apart in Portugal but met in Danbury, to where many people emigrated from the mountainous parts of Portugal and the Azores. My father moved solo after military service in what was Portuguese Mozambique then a stint in Nashua, NH. My mother’s entire close family immigrated in the mid 60s after earlier generations (including my grandmother who turned 102 a few months ago) returned to Portugal from New Bedford, MA during the Great Depression. Friends who know my roundabout transatlantic family history say it is not a surprise that I wound up in London. Despite being an ocean away, I’m happy to be very close to Webb in several ways.

Value of Hard Work and Education
With essentially all of my interactions until kindergarten being Portuguese-speaking extended family and babysitters – other than a bit of Sesame Street and cartoons – I entered kindergarten with very little English. With the US generally being a great assimilator and probably some long-forgotten hard work from me, I, along with my brother and cousins in the same boat, quickly graduated to English as our first language. My parents came to the US with little more than decent job prospects through family friends, so we all saw the value of both hard work generally and education specifically. My parents invested in Catholic schooling – and lots of Lego – for me and my brother. My parents happily paid for my brother to get his mechanical engineering degree at Rensselear, and would have done the same for me, but surely it was more comfortable all around that I had a full-tuition scholarship at Webb. With socio-economic mobility nowadays not being as strong as it was in the 70s to 90s, and although the US is still far ahead of most of the world, the full-tuition scholarship at Webb is so valuable – even if it is not quite enough to meet the needs of all.
Finding Webb
I only barely remember now but after my parents dissuaded 12-year old me from trying to become a chef or start my own construction company (Thank you again for that!), surely I wanted to be an engineer. I investigated top engineering programs in the Northeast then visited several. Webb was love at first sight. First literally, because of the amazing campus, but also the small tight-knit community. Secondly, the pitch to me from an underclassman that ships are the perfect type of machinery to design because they involve disparate, challenging, interesting topics while at the same time many ships are simple enough that one person could complete the most interesting 80% of the design, leaving the detailed but often less interesting work to others. While this description is probably not 80% true, it is very powerful and I do very regularly repeat it. Unlike many Webbies who were very interested in sailing or military ships, although I was always fond of submarines, it was global commercial shipping that appealed to me. It is the intersection of my loves of applied science, geography and economics. Through yet another circuitous route, this led to me running a portfolio of over 60 ships from London for institutional investors. The practical aspects of the Webb education were big selling points to me. This was primarily winter work, but also field trips. With hard work being so highly valued from a very early age due to my family background, and at one point having wanted to start my own business before I was 20, the practical experience was a big differentiator versus other programs. Winter work also helped build lifelong bonds. I was lucky enough to not only be with Dean Werner twice for winter work but also celebrate his wife’s birthdays then. My favorite field trip was to the Sealand Quality, arranged by fellow Trustee Manny Hontoria. The legendary late Prof. Rowen in his characteristic wit said it could have been called the Sealand High Quality if it only had an MAN B&W engine!

Achieving My Goals After Graduation
My Webb education, both in the narrow and broader senses, gave me a strong intellectual foundation, commitment to hard work and confidence that I could then build upon in my career. It prepared me well for being one of the youngest Masters in Finance (“MiF”) students at London Business School in ‘99/’00 and later among the older Chicago Booth executive MBAs in London ‘16-‘18, as well as my time in investment banking and investment management. Towards the end of my MiF, due to reasons familiar at Webb, I pulled an all-nighter after only basic knowledge of a math modelling package to design and price a complex financial derivative that earned an A+. Since completing my MiF, I have worked in high-performing organizations, advising on large corporate deals or equity raisings, bidding on large infrastructure assets and most recently building and running a large portfolio of globally-trading commercial ships with capital raised from very sophisticated investors including large pension funds. My personal background and Webb education gave me the broad and deep technical foundations and confidence to succeed.
Giving Back
Coming back to an earlier point, I’m an ocean away from Webb but am privileged and extremely pleased to be very close in several ways. After all, the traits I brought to and that were reinforced by my Webb education gave me the skills and confidence to facilitate my transatlantic journey and professional evolution. I’ve been lucky enough to be in a position where I can increasingly give back meaningfully financially. Separately, for nearly at least 7 years I’ve been giving a guest lecture to freshmen on buying a ship, making analogies to buying a house while also touching on many of the interesting commercial aspects of the global shipping industry. Other than family celebrations / holidays, this is always one of my favorite days of the year. A few years ago I joined the Webb Board of Trustees, and soon became Finance Chair as a small part of a broader well-planned succession program. We have such a strong, dedicated and increasingly diverse Board. This shows just how important Webb is not only to alumni, but the maritime industry. As John Malone and of course others say about the Heritage Society, it is never too early or too late to give back. I’ve been lucky and very pleased to be able to give back in different ways, and especially hope this helps well-deserving students who also want to give back however they can in the future.
Remembering Dr. Bruce Stephan
The Webb community mourns the passing of Dr. Bruce Stephan, who left us peacefully on December 28, 2023, at the age of 81. A native New Yorker, Dr. Stephan touched generations of Webb students through his 35-year career as a professor of mathematics at Webb Institute. He retired on June 30, 2007, and then became a Faculty Emeritus of Mathematics.
Even after retirement, Dr. Stephan’s love for teaching never dimmed. He taught his own children and grandchildren and tutored many others.
Dr. Stephan was an avid musician as well as a polyglot who was fluent in German and Russian. He loved to travel and explore distant lands with his wife, Jan, and their family. He wanted to ensure that each grandchild experienced his love of travel through carefully planned trips that broadened their horizons.
Rest in peace, Dr. Stephan.
The Role of Artificial Intelligence in Webb’s Academic Program
By Matthew R. Werner
Dean & ABS Chair of Naval Architecture and Marine Engineering
Much has been said and written about the rapid development of AI, and the opportunities, challenges, and risks that this technological revolution creates. In academia, concerns have been raised about the dangers to academic integrity that tools such as ChatGPT pose.
Will term papers be the product of a student’s labor or the output of an AI-powered language model? How can a course instructor be assured that the solutions on a student’s exam were not sourced through an online resource that uses the latest in AI. This past summer, Matthew Collette ’99 Professor of Naval Architecture at the University of Michigan posted to LinkedIn that through his testing he found that ChatGPT was able to score a “B” on typical questions from his hydrostatics course, and therefore validating the concerns of educators.

The faculty at Webb shares the concerns about academic integrity expressed by our peers throughout academia. At the same time, as engineering educators we cannot help but to be excited about the capabilities and possibilities of AI. AI tools have the promise to greatly augment the abilities of naval architects and marine engineers. Over the past several years, projects at Webb have explored the use of AI and machine learning on problems such as planning craft ride control and autonomous vessel maneuvering and collision avoidance. There are many ongoing projects across the breadth of the marine industry that seek to benefit from the capabilities of AI. Recent journal articles and news reports explore opportunities to improve ship design, construction, and operations through the application of AI tools.
Webb is fortunate to have the tradition of a robust honor code that is integral to our academic program. The faculty feel confident that the honor code and Webb’s collaborative learning environment will allow the school to navigate the implementation of incorporating AI in an undergraduate program. The faculty’s direction to the students can be summarized as follows: AI is a powerful tool that can enable learning, and it is appropriate to use AI tools for the acquisition of knowledge and the development of skills. Academic integrity is violated when AI is used to do the work for the student, such as writing a paper or solving a complex math problem. The intentional misuse of AI on academic assignments and assessments is an honor code violation.
To ensure that there is a clear understanding between students and faculty of what constitutes acceptable AI usage, this semester the faculty members added statements explaining the limitations on the usage of AI tools in their course policies. In addition, course instructors were encouraged to discuss with the students at the start of the semester their expectations regarding the use of AI in their course. Technology, subject matter, and teaching methods may evolve over time but the commitment to academic integrity and honor are Webb standards that must be and will be maintained.
