IMO's Maritime Safety Committee (MSC) 93rd session, has just approved
the SOLAS amendments in the IMO Polar Code.  
MSC 94 is expected to adopt these new regulations in November 2014.

The MARPOL provisions would be approved by IMO's  Marine Environment Protection Committee (MEPC) 67th session in October 2014, if so it would be
adopted by MEPC 68 in May 2015.

Which means the IMO Polar Code could enter into force 1 January 2017.
