Small Craft 30

All year round, bathymetry happens

with small boats like this from McLaren Technical Services.  I couldn’t tell if it had a name.   Click on the photo above for more info on McLaren.

Ditto . . .  boom boats

they work all year round near oil docks and around vessels where petroleum products are transferred.

Here Carleena Lynn

removes the boom around Double Skin 39 to prepare it to sail.

Occasionally there’s an outa-towner

from UConn. I wonder what they were doing in the KVK in winter…  well, probably  . . . research.

What’s this?

I’m just trying to figure this out.  My best guess is that suspended from a 20-ton capacity A-frame is a set of underwater hands, a sampling device, a seafloor-drill, all tallied 14 tons of instruments  and tools in a seafloor frame. 

I can’t tell you the division of labor between the equipment lowered/raised through an approximately 10′ x 10′ moon pool by the 90′ derrick and the seafloor drill.  My guess is the the seafloor drill can function at great depth.   Note the Panamanian registry.

All those portlights . . .   relate to the 50+ crew the vessel can accommodate. 

The helideck . . . 62′ diameter, can accommodate helicopters of the Bell 412 type, i.e., up to about 3.5 tons. 

If you didn’t click on the equipment and specifications link earlier, my source for all I pretend to know here, you can click here now.  Since she was anchored in Gravesend Bay yesterday, the tide pushing her stern toward shore, I managed to get my first photos of her stern.   I have seen the vessel, working to amass wind farm bottom terrain data, several times since January 2018.   With the green light to transform South Brooklyn Marine Terminal into a dedicated wind farm construction hub, I suspect some interesting and exotic vessels will be transiting the Narrows in the next few years.

All photos and attempted interpretation, WVD.

Maybe a reader out there can explain how this equipment really works and what super-detailed examples of bathymetric chart of the New York Bight look like.
