PrimeShip system aims to cut ship recycling burden


ClassNK has developed a new soſtware package specifically to cut the paperwork associated with Te International Convention for the Safe and Environmentally Sound Recycling of Ships.


T


he adoption of the International Convention for the Safe and Environmentally Sound Recycling


of Ships by the International Maritime Organization (IMO) in May 2009 points to a future where all parties concerned in the life of ships of above 500gt operating internationally, from design to disposal, will have to follow set procedures that ensure that they are recycled in a safe and ‘green’ manner. Under the terms of the convention,


through life responsibility for the ship extends to its preparedness to be recycled and the preparedness of the ship recycling facility to create a recycling plan and receive the ship in a safe and environmentally protected way. One of the critical requirements to achieve this is that the ship must have a fully developed and maintained inventory of hazardous materials onboard, listing their quantity and location, including wastes, and stores. Te inventory is taken to be the base document that ensures the safety and health of workers, prevents pollution, and promotes the substitution of harmful substances and the efficient use of resources. Entry into force of the new convention


could come as early as 2012, with a deadline being set for existing ships five years later by 2017. In the case of new ships, the shipbuilder


will be required to develop the initial inventory, Part 1, upon delivery of the ship, which is to include details regarding the location and amount of the hazardous materials contained in the ship’s structure and equipment onboard. Parts 2 and 3 of the inventory, including operationally generated wastes onboard and stores, will need to be itemised by the shipowner just before recycling. At the final survey stage, before a ship is taken out of service, the ship recycling

plan will be checked against the inventory of hazardous materials (including bunkers and operational stores) provided by the shipowner, to ensure that they are consistent. Te ship recycling plan itself, based on the inventory supplied by the owner, will need to be approved by the recycling facility’s national authority. To meet the Convention’s standards,


existing ships will pose a separate challenge. In this case, documentation will have to corroborate actions taken throughout the history of the ship, and the process will be even more complex and time consuming. Not only will it involve verification of as-fitted drawings and manuals, but also visual and sampling checks at dry-docking from the bottom of the engine room to the top of accommodation area for identification of materials onboard and their location by the individual or organisation designated as an “Expert”, as described in the convention. The resulting inventory of hazardous materials will then have to be

submitted to the flag administration or recognised organisation for approval. Clearly, collecting and collating


this information represents a massive undertaking and Japan’s ClassNK, points out that creating inventories of hazardous materials onboard all existing ships within the five years aſter entry into force as the convention stipulates, represents a critical challenge for industry. In anticipation of this challenge, ClassNK has moved to develop a specific product to ensure that what international regulators have laid out can be achieved, in the shape of its latest soſtware package – PrimeShip- INVENTORY. (See Figure 1) PrimeShip-INVENTORY is designed to


reduce the workload and cost of preparing the inventory of hazardous materials used onboard ships, because it makes it possible to exchange material declarations between shipyards and their suppliers electronically. Using the package, a supplier creates an Excel-based Material Declaration data file and a Supplier’s Declaration of Conformity
