Edda Fjord, what a workboat

When we weren't learning about Navico and NSS, Palma Harbor offered sights aplenty. Like the 133m (437') superyacht Al Mirqab, owned by an emir who purportedly rarely visits her. I'd love to hang around her bridge myself, but not nearly as much as that full-beam, glass-all-round beauty on the mighty Edda Fjord. I'd spotted her in Palma from my desk in Maine, thanks to Marine Traffic, and cajoled the Simrad demo boat to head over to the heavy duty end of the harbor for a look see. She's called a Multipurpose Platform Supply Vessel, or MPSV, and I have a strong affinity for the type because I got some of my first solid sea time on toddler-size supply boats (about 140-feet) in the early 70's, way off New Orleans. But whereas a lot of Edda's alluring details are available, you too might get intriqued...
Soon you'll realize how modular the vessel is, and how many tasks she can perform even beyond the complexities of offshore oil drilling. For instance, I have no idea what that white apparatus mounted in Palma does, though it does seem to involve the "moonpool". Nor do I know why she's even laying in Palma, though someone suggested "waiting to repair oil loading facilities in Libya". Strange days these are, but at least we know how to put together some remarkable vessels, for work or pleasure.
The "white apparatus" looks to me to be a crane assembly for launching ROV's and the like over the side of the vessel rather than through the moon pool.
