The benefits of implementing standardisation methods in the production of tugs

Recently the buying power of customers has increased as a result of globalisation forcing anufacturers including shipbuilders to produce products with wider variety at lower delivery times. This research aims to optimise the traditional production strategy applied at Damen shipyards for the production of standard tugs. Three levels of...

Improving The Reliability Of Ship Machinery: A Step Towards Unmanned Shipping

Due to the increasing seaborne trade, shortage of officers, constant work of crew on machinery during voyage and the large contribution of human error to shipping accidents it is time for shipbuilding to take the next step in automation. Unmanned shipping is the way to move forward and since the engine room houses some of the most important...

the Hybrid Cutter Dredger: a study on technical and economical feasibility

Growing concern about global warming and climate change intensified the research into more efficient ways of operation in the maritime industry. These researches triggered the use of electrical batteries in hybrid systems. Van Oord aims to operate more efficiently, which implies using less fuel and thus emitting less carbon dioxide. A way to...

Quantification of Manufacturing Complexity in Shipbuilding Projects

In this thesis, a standardised method for quantification of manufacturing activities connected to shipbuilding projects is proposed, based on extrapolation of historical projects. First of all, a hierarchical structure for a technical system breakdown is developed, and different types of relations between systems and components in this structure...

Numerical Research on Elasto-Plastic Response of FPSO Topside Modules Subjected to Blast Loading Aiming at a Simplified Design Method

Structural blast analysis is usually done with two load levels for different design stages; the Strength Level Blast, SLB, and the Ductility Level Blast, DLB. Strength Level Blast is the lower magnitude overpressure (with a higher frequency of occurrence and lower consequence) and Ductility Level Blast is the higher magnitude overpressure (with...

Concept study for offshore seaweed farming: Design and feasibility study for large scale mechanized seaweed cultivation systems

Seaweed has been part of human consumption ever since humanity met with the oceans. As technology developed more applications for these macroscopic algae were discovered. Global population increased, technology advanced and people started to understand the lifecycle of seaweed allowing them to cultivate seaweed. Seaweed is currently cultivated...
