  2. Sea traffic management - Wikipedia

    en.wikipedia.org/wiki/Sea_traffic_management

    STM seeks to create an organized traffic management entity called Sea Traffic Coordination Center(STCC) that will act as a central hub maintaining a record of all vessels at sea using the AIS and/or radar, enabling the distribution of vessel routes between ship-to-ship and ship-to-shore. The STCC together with the AIS and/or radar allows:

  3. Automatic identification system - Wikipedia

    en.wikipedia.org/wiki/Automatic_identification...

    An AIS-equipped system on board a ship presents the bearing and distance of nearby vessels in a radar-like display format. A graphical display of AIS data on board a ship. The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS).

    Heading and track (A to B) 1 – True North 2 – Heading, the direction the vessel is "pointing towards" 3 – Magnetic north, which differs from true north by the magnetic variation. 4 – Compass north, including a two-part error; the magnetic variation (6) and the ship's own magnetic field (5)

  5. Vessel traffic service - Wikipedia

    en.wikipedia.org/wiki/Vessel_traffic_service

    An information service is a service to ensure that essential information becomes available in time for onboard navigational decision-making. The information service is provided by broadcasting information at fixed times and intervals or when deemed necessary by the vessel traffic service or at the request of a vessel, and may include for example reports on the position, identity and intentions ...

    The ship has not moored at Alaska, in spite of the construction of a $26 million, eight-point mooring chain system installed in 2007 in Adak's Kuluk Bay. On 23 June 2009, the SBX was moved to offshore Hawaii in response to a potential North Korean missile launch. Between 2009 and 2010, the vessel spent 396 continuous days at sea. [3] [8]

    A cargo ship sailing from a European port to a US one will typically take 10–12 days depending on water currents and other factors. [6] In order to make container ship transport more economical, ship operators sometimes reduce cruising speed, thereby increasing transit time, to reduce fuel consumption, a strategy referred to as "slow steaming ...

  9. Transshipment at sea - Wikipedia

    en.wikipedia.org/wiki/Transshipment_at_sea

    Transshipment or transhipment at sea is done by transferring goods such as cargo, personnel, and equipment from one ship to another. It is a common practice in global fisheries and typically takes place between smaller fishing vessels and large specialized refrigerated transport vessels, also referred to as “reefers” that onload catch and deliver supplies if necessary.
