It can be of great advantage to consider the sea keeping characteristics of a vessel during the design stage. Severe vessels motions and wave loads are typically associated with specific sea conditions and will vary from ship to ship. It is important to ensure that the design of the vessel has been optimized to minimize the motions and wave loads, or at the very least that is fit for purpose, to work in certain locations and specific environmental conditions.
The Section for Hydrodynamics, Structures and Stability has long experience and in depth competence within sea keeping and concept evaluation for the following ship types:
High Speed Light Craft
Optimizing the design will not only enable the ship to carry out longer operations in harsh environment or choose more challenging trading routes, but it will increase the safety and minimize the risk of the operations. For instance, for vessels where people work on the main deck optimizing the vessel motions to minimize the amount of water on deck will increase the safety and operability. Waterlines and hull shapes may also be optimized such that the slamming loads and are reduced.
Features which are coped with the area of seakeeping include:
General ship motions at different locations of the ship
Green seas on deck
Side by side offloading
Typical deliverables in a seakeeping report may include long and short term statistics of expected extremes or distributions, probabilities, linear transfer functions and animations.
