First, it tries to bypass the problems that many boat factories encounter: of being totally private and detached from the city (even when they are in it: think of Venice’s Arsenale). The walk over the roof that leads directly to the piers and allows bystanders to see through is a good solution to this problem.

The enormous size of the project depends on the needs of the industry. Ship factories are massive by definition. This project can’t avoid that but nevertheless tries to avoid the one-block/one-box solution and presents a varied, nuanced solution.

As to the formal qualities: this floral/organic trend may not be your cup of tea
But it seems to me that this is not simply ornamental, as the holes pierced through the roof help ventilation and allow for visibility. And it can hardly be denied that the junctures between pillars and the roof are not precise and well-made.
If it is ornamental it is as ornamental as the Gothic. But I think we all agree that, architecture historians have since long demonstrated that the Gothic cannot be considered purely ornamental.

The symbolism is perhaps a little too literal: pillars and holes positioned as to simulate the formal configuration of an archipelago (with its obvious associations to the sea), but – personally – i can hardly find this a major drawback.
