Philippe Rouzeau, Manager of the Shipyard Team, Almacam, explains how it solutions can help shipyards shave production costs and increase efficiency.Almacam is a 45-year-old, employee-owned company created by researchers that were mono-focused on developing nesting algorithms in a laboratory of Grenoble University, France, aiming to bring this nesting algorithm tech to the industry.According to Rouzeau, it is the world's only independent CAD-CAM software publisher offering CAM solutions across industries…

The maritime industry is often criticized as being slow to adopt new technologies. While ship building is an age-old industry, it is also varied: fishing, commercial, inland, marine construction, energy, passenger, recreation, defense, and the list goes on. Each sector serves a different purpose, and bespoke vessels fulfill different missions, operate in different environments, and are subject to different regulatory profiles. As a result, our industry abounds with unique solutions…

Late last year we caught up with Robert Ekse, President, Elliott Bay Design Group (EBDG), for his take on how the Future Fuels debate is effectively shaping maritime technology development and vessel investment.Most reading these pages know the EBDG name, but can you give us a quick update?Elliott Bay Design Group has been around for a long time, [at first] primarily focused on ferry design and refurbishment. We've branched out over the years in many different directions, including tugs and barges and other workboats.

This story spans a long period of time, but begins with a note I received recently on an earlier column from a reader named Allan Berger. He commented on the OODA loop concept in my “Pondering Truths in Design” column in the September MREN issue.He provided his approach that closely follows the OODA loop concept, which follows the principle of always gathering all the facts before speaking. That led to a discussion on decision making. Decision making is an extremely important concept that sets the course of human development, and is central to effective engineering.

Supporting hydrogen propulsion and foiling technologies development to reduce emissionsLogistics provider Marinetrans is now partner of the foiling hydrogen boat project of Delft Technical University. Together with other maritime companies Marinetrans now supports this diverse team of students to compete with a foiling hydrogen-power boat in the Monaco Energy Boat Challenge, a project to exhibit viable sustainable propulsion solutions.At Marinetrans, several emission-reduction schemes are currently unfolding…

In producing a column for the Marine Design issue, I considered a number of subjects, but in starting to write about them, somehow my mind connected to “Beam is Cheap.” I have a faint memory of being made aware of this during a discussion of a ship design by a design luminary very early in my career, but I don’t remember who it was.When first putting pencil to paper on some design, I always think about that when I make my first rough sketch. It is a very powerful truism, and over…

Naval Architects can predict many things with great certainty. But the sea is an unpredictable task master and there are still a number of areas where it is difficult to get a technical handle on the problem.High speed planing boat stability is one of those areas.Planing hull design is incredibly complicated and dynamic behavior is actually more difficult to predict than the dynamic behavior of airplanes. (Let me say it again: Aerospace engineering (I am one) is sandlot compared to Naval Architecture).Meanwhile thousands…

The Incat Crowther 35 is being built by PT Kim Seah Shipyard Indonesia, a wholly owned subsidiary of Singapore’s publicly listed Penguin International Limited, using Incat Crowther’s Digital Shipbuilding solution, a process that is designed to bring the designer, shipyard and owner together in one cohesive process, from concept through delivery.A feature of Incat Crowther’s Digital Shipbuilding solution is a 3D digital model of a ship…

With the regulated catch quotas of contemporary fisheries, design versatility for a fishing boat can be important. A new 19.8 x 7.3-m (65 x 24-ft.) combination crab trap and groundfish trawler designed by NAVANEX for building by Chantier Naval Forillon, both of Gaspé, Quebec, Canada is a fine example of this. Owners, Listuguj Mi’gmaq Government, anticipate accepting delivery in April of 2022.The steel-hulled vessel will have a raised fo’c’sle design with an aluminum pilot house. When crab fishing, the clear, aft deck will be capable of carrying up to 150 collapsible, 100-pound crab pots.

As naval architects and marine engineers we are familiar with the design spiral. While design is not truly a spiral, we use the concept to remind ourselves that all pieces of a ship design interact. The design spiral is not a standard figure and can be simplistic or overcomplicated.A Google search image summary provides dozens of interpretations, all investigating different variables, with the only commonality that all spirals start with the “mission” variable.Figure 1 is an old…

Since the 1980s there has been a remarkable revival of ferry services in many U.S. waterfront cities, but COVID-19 has wreaked havoc on the most profitable component of these services: the commuter runs. With post-COVID work-at-home arrangements and part-week in-office work, these ferry services have suffered a tremendous loss of income. But there are glimmers of hope that a recovery is likely, although in a different form, in a different world.Commuter runs are often the bread and butter portion of a ferry services…

Unexpected mooring breakouts are a risk during offshore STS operations. SafeSTS and Gall Thomson aim to offer a solution, launching the Protective Transfer System (PTX). Using the flip-flap marine breakaway coupling technology used within other Gall Thomson products for more than 20 years, the PTX is designed to provide rapid, safe, on-demand release within the marine hose transfer system.An ultra-compact system which includes its own HPU and transport and reset skid, the PTX is located directly over the vessel’s manifold drip tray…

Chris Wiernicki, CEO, ABS, discusses the evolution of multi-physics simulation and its importance in reaching decarbonization goals through 2050.As the pace of technological evolution rapidly quickens, shipowners are increasingly forced to embrace change to ensure their fleets stay in compliance with new regulations and stave off obsolescence.Going forward, efficient, cost-effective delivery of goods from ‘point A to point B’ must be done in a more environmentally benign manner…

My brother, who is the executive editor of my favorite boating magazine (Soundings), and I occasionally send strange tidbits to each other by email. For some reason he sent me an email about the 17th Century ship Vasa and focused on one of the causes of the vessel’s failure to float properly.This is the Wikipedia paragraph he focused on:"The use of different measuring systems on either side of the vessel caused its mass to be distributed asymmetrically, heavier to port. During construction both Swedish feet and Amsterdam feet were in use by different teams.

Hakone Maru, a container carrier formerly owned and operated by NYK, has been recognized by the Japan Society of Naval Architects and Ocean Engineers (JASNAOE) as "Japan's first new container carrier that realized efficient maritime transportation."This honor is given to vessels that have historical, academic, and technical value, promote public understanding, and are seen as symbols of cultural heritage for future generations. Another NYK vessel, Hikawa Maru, a historic ocean liner permanently berthed as a museum ship in Yokohama…

The evolution of commercial ship design and construction now includes a first in the U.S.: the first commercial U.S. vessel designed, built and verified using an end-to-end 3D design process, a project coordinated through ABS, Robert Allan Ltd.
