Interpretation

  1 "Bilge injection system" is the same as "direct suction" referred to in SOLAS regulation II-1/35-1.3.7.1 and 3.7.2 and is understood to mean "emergency bilge suction", which is used to discharge overboard large quantities of seawater accumulated in engine-room bilges using the main circulating pump or another suitable pump as permitted by SOLAS regulation II-1/35-1.3.7.2.

  2 The requirements for the controls of the "valves serving a sea inlet, a discharge below the waterline or a bilge injection system" should not be applied to valves serving an emergency bilge system, provided:

  • .1 the emergency bilge valve is normally maintained in a closed position;

  • .2 a non-return device is installed in the emergency bilge piping; and

    • Note: A normally closed non-return valve with positive means of closing is considered to satisfy both .1 and .2 above.

  • .3 the emergency bilge suction piping is located inboard of a shell valve that is fitted with the control arrangements required by SOLAS regulation II-1/48.3.
