Basic simulation of ship motion in regular waves. Motion is computed as follows: 1. Ship and sea are modeled with triangles. 2. Ship's hull has a volume and a mass which define all the moments of inertia. 3. Intersections between triangles of the hull and triangles of the sea are computed to get the submerged surface of the hull. Result is a list of small triangles which are all submerged. 4. Pressure force is computed for all the submerged triangles of the hull. 5. Motion is given by the pressure and gravity forces combined with inertia. Written in C# 3.5 and XNA 3.1 with VS 2008 by Edouard Halbert. See http://simship.codeplex.com for the source code and the release.
Movements of Philippine-flagged Container ship ACX CRYSTAL, which collided with US Destroyer USS Fitzgerald south of Tokyo Bay in Japan in a rare incident on busy waterway. USS Fitzgerald (DDG 62) was involved in a collision with the container ship ACX Crystal, while operating about 56 nautical miles southwest of Yokosuka, Japan. The US Navy has identified seven sailors who were killed when their destroyer collided with the container ship. The coastguard said none of the 20 crew members on board the container ship ACX Crystal were injured.

NEW VERSION AVAILABLE: https://www.youtube.com/watch?v=CP-TcDtSFDI&hd=1 A week of ship traffic on the seven seas, seen from space. Get a glimpse of the vibrant lanes of goods transport that link the continents. The vessel movements were captured using newest terrestrial and space-borne AIS technology from FleetMon and its partner Luxspace. The records cover the world's merchant fleet with some 100.000s of cargo ships, tankers, ferries, cruise ships, yachts and tugs. FleetMon provides advanced fleet monitoring services, software APIs, reports and analyses of maritime traffic data. The inset shows live monitoring with the FleetMon Explorer software.

A simple technique with the right tools applied on right satellite data can give enormous information. And this is what Planet is applying on data collected by its small doves. From its huge data stack, Planet is analyzing movement of ships at the Singapore Port. Let’s dive in to see how the company analyzes the data. On March 17 and 18, 2017, Planet’s PlanetScope shoots massive container terminals. Let’s zoom in to see how many ships are unloaded/loaded at the Quai highlighted in red. The area highlighted in red shows number of ships. Ship pixels are light compared to water pixels so in this tiny area of interest, it is easy to distinguish between the two. A little analyzes and back of the book calculations reveal there were 8,778 ship pixels on March 17. And, on March 18 pixel counts wer...
