Enhancing offshore service vessel concept design by involving seakeeping: Developing a framework to efficiently design high-performance offshore service vessel concepts

The growth in the offshore wind industry sees an increased demand for offshore service vessels (OSVs). These vessels often operate in harsh conditions, and their performance is heavily dependent on their seakeeping characteristics. Conventional ship design processes fail to effectively consider seakeeping early in the design process, leading to...

Combined shape and size optimization of an offshore crane

Tetrahedron is working on a new design for large offshore cranes that can lift higher. This is necessary due to the increasing size of offshore wind turbines, and the inability of the conventional cranes to scale up without needing a larger ship that is carrying them. To compute the forces working on the trusses of the crane structure,...

Optimization of offshore wind farm installation procedure with a targeted finish date

Offshore Wind Farm (OWF) installation procedure is a complicated phase requiring excellent management of resources for timely completion of tasks. The wind farm installation period involves crucial stages like streamlining onshore logistics, transportation of components on vessels, installation of foundations, wind turbines, and cable laying,...

Support Structure Optimization: On the use of load estimations for time efficient optimization of monopile support structures of offshore wind turbines

Over the years, the installed capacity of offshore wind turbines is increasing rapidly. However, the Levelized Costs Of Energy (LCOE) is still higher than the LCOE of traditional energy production methods like nuclear power or energy from coals or gas. This research focuses on a further decrease of the LCOE, by minimizing the mass of a monopile...

A Computational Intelligence Approach to Voltage and Power Control in HV-MTDC Grids

An ever increasing interest in renewable energy sources (RES) in order to reduce global carbon emissions and alleviate problems posed by climate changes has lead to dramatic increase particularly in offshore wind energy projects. Several different projects are currently being executed and so many are being planned for the future. The location of...
