M/S Eva 316 for Estonian Maritime Administration M/S Eva 316 conversion to Pärnu Bay ice breaker and oil combatting vessel has been ordered from a Tallinn based shipyard BSRLT – group. Eva 316 is a sister vessel to Seili and Letto. he yard has ordered the workshop drawings also to be carried out by ILS. ILS has realized modification design work of M/S Seili, which has been lengthened by 7.8 m in the middle part and provided with open water and ice oil recovery systems and storage tanks. The modification works included a total rebuild of the propulsion system and comprised the installation of two Steerprop T SP 25 units as a part of the new dieselelectric propulsion system. A contract of the modification work was signed at the end of January 2003 between the Owners, Finnish Maritime Administration, and the yard, Aslemetals Oy. The oil combatting responsible partner is the Finnish Environmental Institute. ILS was responsible for workshop design work for the yard. M/S Seili conversion was carried out in the Aslemetals Oy Olkiluoto Yard and delivered in February 2004. M/S Seili has been outfitted also for emergency towing and fire fighting purposes. The vessel center part of the M/S Eva will be same as in Seili, but the bow and stern will be completely different. M/S Eva 316 will have the diesel electric azimuth propulsion of 2x 2200 KW, as the new propulsion power in Seili after the conversion was 2x1100 KW. The stern will be rebuilt correspondingly. Eva 316 will also get a totally new ice breaker bow. M/S Eva 316 will be rebuilt during 2005. A sister ship for M/S Seili, EVA316 in Tallinn has also been studied by ILS in order to investigate possibilities for modifying her also into an oil combating vessel and additionally into an ice breaker to Pärnu Bay area. A preliminary study in cooperation with Helsinki University of Technology Arctic Navigation Unit was carried out during winter 2004-2005 and the results show, that a multipurpose EVA 316 will be possible.
