The scienti? c research which provides the foundation of these structural and wave esti- mates is not new. They are the outcome of nu- merous empirical investigations over the past decade, which have proven their underlying ef- fectiveness. However, it has not been possible until recently to combine them in one simple, easy-to-use package.

In comparison to other non-destructive fatigue detection methods, this provides an optimized experience and can substantially reduce inspec- tion costs compared to conventional testing.

Staying Out of Dry Dock

Navin Thakur, director at Drewry Maritime

Research, noted last year that ship ? nanciers are now rarely willing to estimate that a ship will have an average economic life of 25-30 years.

In an era in which almost every sector has overcapacity concerns and freight rates which are frequently unable to cover OPEX and debt repayments, it won’t take much off-hire to leave a shipowner or operator underwater. With the arrival of this development from NAPA, it is now possible to collaboratively use existing technologies and data to ? nd valuable informa- tion about a ship’s actual condition which was previously dif? cult to obtain, and lead to major positive changes to the current state of vessel performance and optimization. Think about it: 17
