CATEGORY 8-MARINE

8A    SYSTEMS, EQUIPMENT AND COMPONENTS
 
8A001     Submersible vehicles and surface vessels, as follows:


Note:
For the control status of equipment for submersible vehicles, see:
Category 5, Part 2 "Information Security' for encrypted communication equipment;
Category 6 for sensors;
Categories 7 and 8 for navigation equipment;
Category 8A for underwater equipment.

  1. Manned, tethered submersible vehicles designed to operate at depths exceeding 1000 m;
  2. Manned, untethered submersible vehicles, having any of the following:

    1. Designed to 'perate autonomously' and having a lifting capacity of all the following: 

      1. 10% or more of their weight in air; and
      2. 15 kN or more; 
    2. Designed to operate at depths exceeding 1000 m; or 
    3. Having all of the following: 

      1. Designed  to continuously 'operate autonomously' for 10 hours or more;
      2. 'Range' of 25 nautical miles or more;  (L.N. 226 of 2009)

         Technical Notes:

        1. For the purpose of 8A001(b), 'operate autonomously' means fully submerged, without snorkel, all systems working and cruising at minimum speed at which the submersible vehicle can safely control its depth dynamically by using its depth planes only, with no need for a support vessel or support base on the surface, sea-bed or shore, and containing a propulsion system for submerged or surface use.

        2. For the purposes of 8A001(b), 'range' means half the maximum distance a submersible vehicle can 'operate autonomously'.  (L.N. 226 of 2009)

  3. Unmanned, tethered submersible vehicles designed to operate at depths exceeding 1000 m, having any of the following:

    1. Designed for self-propelled manoeuvre using propulsion motors or thrusters controlled by 8A002(a)(2); or 
    2. Having a fibre optic data link; 

  4. Unmanned, untethered submersible vehicles, having any of the following:

    1. Designed for deciding a course relative to any geographical reference without real time human assistance;  (L.N. 161 of 2011)

    2. Acoustic data or command link;  (L.N. 161 of 2011) 
    3. Optical data or command link exceeding 1000 m;  (L.N. 161 of 2011) 

  5. Ocean salvage systems with a lifting capacity exceeding 5 MN for salvaging objects from depths exceeding 250 m and having any of the following:

    1. Dynamic positioning systems capable of position keeping within 20 m of a given point provided by the navigation system; or 
    2. Seafloor navigation and navigation integration systems for depths exceeding 1000 m with positioning accuracies to within 10 m of a predetermined point;

  6. Surface-effect vehicles (fully skirted variety) having all of the following characteristics:

    1. A maximum design speed, fully loaded, exceeding 30 knots in a significant wave height of 1.25 m (Sea State 3) or more;
    2. A cushion pressure exceeding 3830 Pa; and
    3. A light-ship-to-full-load displacement ratio of less than 0.70;

  7. Surface-effect vehicles (rigid sidewalls) with a maximum design speed, fully loaded, exceeding 40 knots in a significant wave height of 3.25 m (Sea State 5) or more;
  8. Hydrofoil vessels with active systems for automatically controlling foil systems, with a maximum design speed, fully loaded, of 40 knots or more in a significant wave height of 3.25 m (Sea State 5) or more;
  9. Small waterplane area vessels having any of the following: 

    1. A full load displacement exceeding 500 tonnes with a maximum design speed, fully loaded, exceeding 35 knots in a significant wave height of 3.25 m (Sea State 5) or more; or 
    2. A full load displacement exceeding 1500 tonnes with a maximum design speed, fully loaded, exceeding 25 knots in a significant wave height of 4 m (Sea State 6) or more;

      Technical Note:

      A small waterplane area vessel is defined by the following formula: Waterplane area at an operational design draft less than 2 x (displaced volume at the operational design draft)2/3.  (L.N. 132 of 2001)
