Relevant for ship owners and managers of chemical tankers and OSVs.
When new chemical products or product mixtures are offered for bulk shipment, they are normally subject to a so-called tripartite agreement. The purpose of a tripartite agreement is to enable a new product to be shipped relatively quickly in an interim period before the IMO performs the final assessment.
The agreement is valid only for the signatory countries and for a maximum of three years. This implies that the cargo can only be shipped on vessels flying the flag of a signatory country and between ports of the countries which are part of the agreement.
The IMO will perform a final assessment of the products based on their physical and toxicological properties as submitted by the producing country. The product will then be valid for all countries without any expiry date, and included in the standard Certificate of Fitness (CoF) product list. The carriage requirements may change from the tripartite agreement.
While finally-assessed products which a ship is certified to carry are included in the standard CoF product lists, a single product addendum is added to the CoF covering that specific tripartite product only. The new tripartite list will include all current tripartite products at the time of issuance for which the ship may be certified and the flag of the ship is a signatory state.
In particular, for vessels that frequently request tripartite addenda, typically parcel chemical tankers, the new product list will be a better alternative than applying for an addendum each time a tripartite product is to be carried.
On the new list, the signatory states and the tripartite expiry dates will be shown for each product, in addition to the standard information such as in which tanks the product may be carried, footnotes and the MARPOL pollution category.
The new tripartite lists, as the existing addenda, will only be issued on request. The fee for the tripartite list will not exceed the price of two or more addenda. The benefit will be a higher probability that the next tripartite product to be shipped is already covered by the CoF, reducing administrative burden and certification cost.
At the next opportunity, the operator should strongly consider applying for a tripartite list instead of an addendum, thus getting the vessel certified for all products currently available.

20 February 2018 | Technical | NEWSShaft alignment and propeller shaft aft bearing performance – recent trends call for actionRecent experience reflects concerns on propeller shaft aft bearing performance on some oil lubricated installations, e.g. ships with single stern tube bearing, during turning conditions involving hard-over steering angles in the upper speed range (MCR). This also coincides with evolving trends comprising of larger and heavier propellers operating at a lower RPM and different types of stern tube lubricants. This news aims to elaborate the basic logic, criteria and recommendations associated with propeller shaft aft bearing performance.
24 January 2018 | PSC | NEWSCold conditions call for extraordinary measures for ships, equipment and crewCanada and other areas close to the Arctic are currently experiencing extremely low temperatures, and owners calling at ports in these areas are obliged to prepare accordingly. This includes paying particular attention to safety and navigation-related equipment which may be damaged or impeded from working properly under such conditions. This PSC news summarizes the most important measures to be assessed for cold climate navigation.
05 January 2018 | Statutory | NEWSAmendments to MARPOL Annex V (regulation for the prevention of pollution by garbage from ships)The amendments to MARPOL Annex V adopted at MEPC 70 will enter into force on 1 March 2018. The changes include criteria for determining whether cargo residues are harmful to the marine environment, and a new Garbage Record Book format with a new garbage category for e-waste. This news provides a summary of the new regulations.
