Why assessing low probabilities of failure by extrapolation could be required

Why assessing low probabilities of failure by extrapolation could be required
June 2019 - “Calculating the Probability of Failure (PoF) may fail when this value is very low”, explains Jack Reijmers, Specialist Engineer at Nevesbu. The Probability of Failure is the probability that the loading exceeds the load carrying capability or resistance. A safe structure implies a low PoF. However, sometimes the PoF is too low to calculate. The analysis produces a distribution of probabilities, but failure lies...

The performance of full electric battery/fuel cell powered submarines compared to conventional submarines

The performance of full electric battery/fuel cell powered submarines compared to conventional submarines
April 2019 - Both fuel cells and batteries are considered the solution to achieve emission free transport in multiple civil industries. The undersea defense industry can profit from this, since both technologies are applied in submarine designs.  However, will it also be possible to move from a hybrid power plant to a full electric power plant? And what are (with respect to the performance) the essential differences, advantages and...

How to find the most suitable power plant during early-stage design?

How to find the most suitable power plant during early-stage design?
February 2019 - For economic and environmental reasons, commercial vessels increasingly need to be optimised towards their mission. This optimisation mainly influences the onboard power plant, since this is a large contributor to the operational costs of a ship and the main source of emissions on board. At the same time it becomes ever more challenging to find the power plant that best matches the wishes of a client during early-stage...

Former Nevesbu graduation student Marjolein receives KNVTS Maritime Students Award 2018
November 2018 - The Maritime Students Awards is an award for ‘the best of the best’ graduation students. In 2017, Marjolein graduated from the Technical University in Delft with an impressive 9. The subject of her graduation thesis was ‘submarine propulsion plant design using mean value first principle models’.

How to quickly gain a complete overview of the as-is situation of ships

How to quickly gain a complete overview of the as-is situation of ships
August 2018 - The existing or ‘as-is’ situation is an important starting point for design work in ship maintenance or modification projects. To ensure that any new systems and configurations will ‘fit’ instead of resulting in a design clash, Designers need exact information about the current situation on board. Unfortunately, many ships lack proper documentation, and, in some cases, there are no drawings available...
