FEATURE MAIRNE DESIGN Classification, by Germanisher Lloyd, was updated accordingly for the new service. According to Tero Vauraste, CEO of Arctia Shipping Ltd, stand-by can be achieved quite affordably, as the crew on stand-by anyhow services the icebreakers in summertime. IB Kontio must be ready to engage in oil combating within 24 hours regardless of the time of the year. Vauraste points out that the vessel fits very well to this task, as the crew is skilled in operating the vessel in a con- fined space and close to other vessel. In addition IB Kontio can handle ice man- agement and has towing capability. "As this is a very cost efficient way to provide oil combating services, compared to con- structing a completely new ship for this purpose, we would like to do the same conversion also to sistership icebreaker IB Otso, if a possibility arises," Vauraste tells Maritime Reporter. Equipped with a skimmer, oil collection is now also pos- sible to be carried out when the sea in covered with ice, to some degree. The crew has received IMO OPRC Level-1 or Level-2 oil pollution combating training. Advanced Oil Combating Equipment The oil combating equipment is pro- vided by Lamor Corporation Ab, a Fin- land-based company supplying oil spill recovery equipment globally. The equip- ment is readily installed onboard the ice- breaker in summer and is stockpiled ashore when the vessel is deployed in ice- breaker duties. The installation of the equipment takes a maximum 12 hours. The equipment consists of one pair of Lamor's rigid 12m sweeping arms, type LS12, each unit with an exchangeable weir skimmer module and brush module. As IB Kontio is 24.2m wide, a total sweeping area of 48m is thus provided. This system uses 6-in. flexible hose for taking the oil onboard. There is a pair of centrifugal oil transfer pumps for the weir skimmer modules, each with a capacity of 300 cu. m/hr. at 6 bar. Oil from the brush modules is transferred using 125 cu. m/hr. screw pumps at 7 bar. The power is provided by two movable hy- draulic power packs, also provided by Lamor. Each unit provides 210/280 bar at 330 l/min. through a 120 kW genset. In order to handle the rigid sweeping arms, Lamor also supplied two 15m/5t Hidroacar cranes placed on each side of the vessel. The vessel is also fitted with a set of 500m heavy duty oil boom type Lamor provided two powerpacks for the oil pumps, and two Hidroacar cranes. Hatecke supplied two lifeboats. The heavy duty oil boom is stored in 125m lengths on own reels.
