MSC 90 – blending and damage stability

At the 90th session of IMO’s Maritime Safety Committee (MSC 90) in London this week, blending and damage stability were important items on the agenda.

Amendments to SOLAS Chapter VI – Prohibition of the blending of bulk liquid cargoes and production processes during sea voyages.
The Committee reviewed the outcome of the discussions held at the Sub-committee on Bulk Liquids and Gases (BLG) which agreed the new draft SOLAS Regulation VI/5-2 which covers the prohibition on the blending of bulk liquid cargoes during the sea voyage, and also prohibits any production process onboard a ship during the sea voyage.

It was agreed that the two parts of this new draft regulation were to be adopted as a single package.

During discussions, the Committee also reviewed a proposal to allow for an exemption towards production processes of cargoes on offshore vessels used in the search and exploitation of seabed mineral resources.

It was agreed to adopt these draft regulations and exemptions as a complete package and this new SOLAS regulation VI/5-2 can be accessed here.

Development of guidelines for verification of damage stability requirements for tankers
The Committee referred the draft Guidelines for verification of damage stability requirements for tankers, together with the associated draft mandatory carriage requirements and any proposed amendments, to the Sub-committee on Stability, Load lines and Fishing Vessels Safety (SLF).

The SLF Sub-committee will meet 18-22 February 2013 when it will review and finalise the draft Guidelines and associated amendments to mandatory instruments to ensure the mandatory carriage requirements of stability instruments.

INTERTANKO will work with its Membership and other industry organisations to develop and submit appropriate amendments to mandatory instruments for the consideration by the SLF Sub-committee.

The draft guidelines can be accessed here and the draft operational guidelines can be accessed here.
