‘ The integration of marine systems at the ship concept stage will be key’
Marine Systems represent a vast family of products and solutions, which are pretty difficult to characterise in just a few words. While a hull or a floater are the most obvious and prominent systems that a ship or platform is made of, many systems are integrated on such a hull or floater and contribute to the overall design and performance at sea.
H
istorically, the most important subsystem is the ship’s propeller. Each propeller has its own
efficiency, characteristics and performance in open water. A series with specific features can be designed generically, as MARIN did in the 70s with the Wageningen B-series, or more recently as we did in cooperation with propeller manufacturers, yards and naval architects with the C, D and F-series. However, Guilhem Gaillarde, Manager of the Ships business unit and coordinating the Marine Systems market, points out that a careful selection needs to be done to make sure that the selected propeller
will fit the actual hull with its appendages and operational profile. “When requirements in performance are very specific, propellers need to be tailor-made for a given operational condition and hull form.” This example illustrates exactly what can be expected from any subsystem that is fitted on a ship or floaters. Selecting standard, generic components will match 80% of the cases with 20% effort. To reach higher performance levels more customised solutions are required, which involves a greater effort in terms of concept and integration, he says.
Another example concerns alternative powering of ships, with the introduction of modern wind propulsion techniques that could lead to a drastic reduction of energy use. But their introduction needs to be carefully balanced with the propulsion train, especially regarding the propeller that will need to adapt to underloading conditions to keep working at a high efficiency level. New designs for hulls or added lifting appendages will also be needed. “Piling up marine systems without proper engineering does not sum up their performance. When their integration is well engineered at the concept stage, then it can be a win-win situation,” stresses Guilhem.
