Analyses of ships operating under service conditions, taking into account off-design conditions, transient stages and environmental factors.

Taking into account operating conditions meeting logistic demands

Challenging factor is to meet logistic targets under best possible operational conditions. This may deviate from where the ship is designed for. In general, the ship design targets deviate from the actual in-service conditions. Common practice is to specify a contractual maximum attainable speed and a maximum continuous speed. Here a general trend is that many ships sail less fast as designed for. Furthermore, environmental factors are not always properly accounted for, resulting into possible offsets. Given the fact that the design shows different ideal sub-optimal matches with given operations it of interest to analyse total ship systems to negotiate their given operational demands.

Ketelbink is able to derive operating conditions, quantify the ship performance response and translate this into how logistic demands are met and can be improved.
