Time for a Closer Look at Offshore Wind Turbines
Offshore wind is inching closer to reality off the New Jersey coast. The public review process is underway and the big question is: “Will offshore wind make it past the public opinion barrier?” The advantages of offshore wind are most tightly focused to what now is becoming a screaming need to reduce carbon emissions. Wind… Read more »
Bilge Pump Switches; My Special Nightmare.
Jim Dolan and I had a discussion about a bilge pump repair that went awry and almost simultaneously we expressed frustration about the bizarre variety of bilge pump control installations in boats. We commiserated that in sinking investigations it was always a puzzle to actually figure out how the bilge pumps were configured and especially… Read more »
Aberration; Powerplant design
In my prior blog on Aberration I promised to write a discussion on the propulsion system and the whole powerplant design. It is probably most useful to describe the whole powerplant design process to see how things eventually came together. That makes it a long story, but should be an interesting opportunity to go down… Read more »
Separating Rotzooi from Technical Reality
Note: The Waterpomptang family is fictitious and occasionally a Waterpomptang story appears on the M&O website. Some say their adventures resemble real events, but that is just a coincidence. Bolle was comfortably seated in one of the creaky white oak surplus Liberty ship chairs in Willem’s office above the BuyLo Packy in Red… Read more »
Henk van Hemmen the Elder’s encounter with WWII
In the prior blog I discussed my grandfather’s favorite ship, the HEDEL. I got on the subject because of a weblink my Uncle Ed emailed me. The weblink my Uncle sent me actually referred to the JONGE WILLEM, a ship my grandfather sailed on immediately prior to World War II. During the depression he was… Read more »
Henk van Hemmen the Elder’s Hedel (TBT)
My Grandfather, Henk van Hemmen’s favorite ship was the HEDEL. She was built as AGIRA to LR class for the Norddeutscher Lloyd at AG Weser in 1930.

Aberration; an Update and Personal Critique
Since my blog on Aberration in October last year, the concept has come to life and is now operating to a level where I can ponder my brilliance (right) and mistakes. As a designer it is particularly interesting and cathartic to find yourself on the receiving end of the design. I often write blogs to… Read more »
Dumpster Diving for Truth
As surveyors, we leave no stone unturned. Likewise, our support staff leave no dumpster unexplored.
Leadership, Passion and Commercial Reality
I only met Leon Hess a few times and then only quickly, but our company has been deeply intertwined with Hess Oil almost since Hess Oil’s inception.

The Rough Road to a New Reality. My First EV Long Haul
We have had our car charger at M&O now for a number of months, but today was the first day we had two cars “achargin”. I was fun to provide the hospitality to one of our friends who came to visit, especially since recently I made my first professional EV foray into the Pinebarrens of… Read more »
All the Work that Fits a Blog
Since we updated our website with a blog function in 2011, I more or less committed myself to posting a blog each month. Somehow, I more or less stuck with that commitment, but I just noticed that we did not post a new blog for January 2021. I also noticed that this happens to be… Read more »
Make Mine Half Size (A Late M&O Christmas Present)
As usual the Martin & Ottaway Christmas present is late. But maybe I should call it a New Year’s present anyway. This year it is a story. I wrote it late in the last century. It has sort of been published in various places, one of which was a website that I can no longer… Read more »
The Big Maritime Things in 2020
I ended my 2019 annual review with an admonition not to work like a robot or you will be replaced by one quickly. The comment was intended to warn engineers to be innovative or they will be replaced by robots. Now, at the end of 2020, I have a whole new vision of the effect… Read more »
Sailing to the Future
The 29-day voyage of the “Grain de Sail” from Saint Malo, France to New York, New York, completed on December 16, 2020, was not publicized in the New York Times, USA Today, or any other big-name tabloids. Its cargo of about 14,000 bottles of wine has yet to hit the menus of New York restaurants… Read more »
If You Build It They Will Come
The movie Field of Dreams was a little too dreamy for me, but the main line of the movie: “If you build it they will come”, never quite left me. In some cases it actually could be true. Within the office we have discussed using EV’s for company cars a number of times. While… Read more »
Alla Tsiring on Throw Back Thursday

Pitching your Tent in Dog Doo
Living is nothing more than postponing the moment where you kill yourself. So far so good, but I have come really close a number of times. And retrospectively, mostly due to a lack of attention to the details. One that continues to stand out to me was when I was a student at Virginia Tech…. Read more »
Decarbonization of the Maritime Sector

Coronavirus; Why don’t we think through the problem first?
While our coronavirus experience seems so novel, in the arc of maritime history, pandemics like this are far from unusual. Actually, the most unusual part of the present pandemic is that we have not had to deal with a pandemic like this for over 100 years. Taking into account that in those 100 years… Read more »
New Jersey Global Warming Data to Defeat Deniers

A Method for Providing Audience Reaction in Zoom Style Meetings and Remote Broadcasts
During the pandemic Martin & Ottaway has been conducting a lot of its business in Zoom style meetings. In some ways these meetings are quite effective in resolving technical issues.

COVID-19 and Subchapter M: Will the coronavirus affect the upcoming Towing Vessel compliance date?
The Coast Guard and Maritime Transportation Act of 2004 has sent uncertainty as well as additional audit and survey demands across the towing industry.

As a result, companies are concerned as to whether they… Read more »
Introducing James “Jim” Kline
While Martin & Ottaway has always worked very closely with the United States Coast Guard, we have never had a Martin & Ottaway consultant with a United States Coast Guard background.

The Unpredictability of Innovation in Wheelchair Use
Standard wheelchairs have not changed in decades. It is a chair with wheels and has foot pads to support a person’s feet and to keep them from dragging on the ground.

The Big Maritime Thing(s) in 2019
I actually enjoy taking stock of a past year in its last few days. The office tends to be quiet and a few moments of introspection can be interesting. This year I did not have any real innovations or significant developments in mind as far as 2019 milestones are concerned. I wondered if 2019 was… Read more »

Barbados: The Goldilocks Approach to Sustainability
Mathematically, worldwide sustainable energy is a real possibility, but it will require a very significant change in thinking, attitudes, efforts, and financial commitments to accomplish.

“Sustainable Energy – without the hot air” David J.C. MacKay (1967-2016) – Wave Resource Review
Sustainable Energy – without the hot air is an excellent text covering the various renewable power sources and their potential contribution to the energy supply mainly focused on the United Kingdom.

OHMSETT, A Hidden Technical Asset
Maritime is too easily defined as ships passing in the night, and most of our maritime lives we work to make sense of the darkness. Sometimes you know the ship is there, but since it does not appear to be a danger you don’t pay attention. In many ways that is poor form. There is… Read more »
The Jeep Stick; I’ll Take Accidental Perfection Any Day
This will be a longer story, but it tells how random timing, the passage of time, weird coincidences, sticking with what works, and a sense of fun, can result in overall near perfection.
