After modification and permanent ballast was in-situ, an inclining test was conducted to certify the weight and centre of gravity of the vessel under the supervision of the site surveyor. Based on the results obtained from the test and the proposed loading conditions, the stability expert teams verified the compliance of the vessel with the stability requirements including the effects of the shift of livestock and fodder in pellet from and the effect of wind. Removal, renewal, installations… Since it is a conversion from a RoRo Carrier to a Livestock Carrier, the existing securing arrangements, ramps, stern door, which were designed for vehicles, were all removed and new ramps and side loading doors were fitted for the loading and unloading of the animals. Animals pens were installed on board based on the accepted dimensions to keep the livestock safe and secure, and the metal floor was coated with special anti-skid paints to provide a non-slippery surface. »Considering it is a closed livestock carrier, the most important consideration was the installation of mechanical ventilation for each space«, the classification society emphasizes. This provides air circulation and sufficient air change for the entire volume of air in that space i.e. to achieve the required minimum amount of air changes per hour. Also, for the electrical supplies for the main and back-up systems, two additional generators were fitted – one on the forward and one on aft deck. Furthermore, fodder tanks were fitted at the aft of the vessel to carry the feed for the animals along with a distribution facility to carry the feed from the tanks to each deck with enough spaces to supply feed to animals. Reverse Osmosis (RO) Plants were installed for the continuous supply of fresh water for the animals. The fresh water from the RO plants is stored in the tanks and continuously supply water through pumps and distribution lines to the local water pods situated in every corner of the animal pens. A permanently fixed lighting system was installed to give a sufficient level of illumination in passageways between the pens and access route and also, an emergency permanently fixed lighting system was also provided in case of failure of the main electrical system. Based on several calculations to improve stability, permanent ballast was also installed on-board under supervision of IR class. The start of a series? »Our first conversion project from a RoRo carrier to a Livestock Carrier met our client’s expectations without any hassle or delay,« an IR Class spokesperson tells HANSA. The class society’s teams were able to keep the project on track during all stages of the conversion by providing round the clock technical support and guidance to the yard, designers and the owners. According to IR Class, »each and every matter« was discussed with all the parties involved at each stage of the project »with the prompt actions by all involved being the key highlight of this project.« In spite of the challenges and complex work, IR Class intends to continue to carry out such projects in the future. Apparently there are already more or less concrete plans: »Since this conversion and the confidence of the owner in the abilities, IR Class has been awarded other conversion projects. We are now working on a similar conversion for the ›City of Barcelona‹,« the Indian classification society says. M M 36 HANSA – International Maritime Journal 08 | 2020
