Brodosplit Delivers Ice-Class Product Tanker
The fourth in a series of 74,999 dwt 1A Ice-class product tankers has been delivered by the Brodosplit Shipyard in Croatia to Marinvest of Gothenburg, Sweden. The vessel, which is built to Marinvest's own design, is double hulled and can operate in areas with ice thickness up to one meter. It has a length overall of 228.6 m and a cargo capacity of 85,659 cu. m. that can take 55,000 tons of naphtha. Corrugated bulkheads with no internal structures in the cargo tanks have also been specified for easy cleaning and quick changes between cargoes. Seven segregations are possible, including slop tanks for flexible operation with part cargoes. The vessel is unique because it combines the 'flexible' corrugated bulkheads design with a large cubic capacity so ensuring cargo handling flexibility together with an ability to accommodate larger volumes of low density cargoes like Naphtha and condensates. FRAMO submerged pumps and deckheaters means it is possible to accommodate a variety of cargo parcels. High discharge rates can be achieved because it is possible to run six cargo pumps in parallel, or possibly more with the right mix of lighter cargoes. She is designed with 'older' DNV notation designed for 20 years trading on the North Atlantic which is comparable to 25 years with the new Common Structural Rules system. To further enhance safety, Marinvest has designed and built a system for emergency propulsion that reportedly is the first of its kind designed for a slow speed two-stroke main engine. Using the hydraulic power from the FRAMO cargo system, the system can ensure the vessel maintains a speed of 910 knots in moderate weather. The PTI system, when combined with the CP Propeller, is designed to give good maneuverability and power control. The ballast water piping has been arranged to facilitate the future installation of an approved ballast water treatment system. Hull design has been optimized with transverse ice framing to reduce weight increase caused by ice strengthening. The reduced weight will reduce fuel consumption and/or give larger cargo carrying capacity at a given draft.
Key Vessel Features: � "Take me home" emergency propulsion system, designed to ensure 9-10 knots in moderate weather and drawing power from the FRAMO cargo system. � Large cargo capacity within commercially important main dimensions: Cargo capacity 85,650 cu. m. allows for a cargo of 55,000 tons of naphtha; 74,999 TDW at scantling draft 14.2 m allows for full cargo of diesel; 61,000 TDW at Design draft 12.2 m (40 feet), giving large cargo carrying capacity into shallow harbors. � Cargo tank arrangement for flexibility: Corrugated bulkhead and no
internal structure in cargo tanks; Fast, easy cleaning making change between different cargoes easy; FRAMO Submerged pumps, deck heaters, 6+1 segregations giving large flexibility to take multiple parcel cargoes. � Ice capacity but with same open water performance as other LR1 ships Ice class 1A means that the vessel is designed to operate in ice channels with ice thickness up to 1 meter; part or full year operation possible in many other arctic Areas; optimized hull design with transverse ice framing etc to reduce weight increase caused by ice strengthening.
� Modern Navigation, Communication and Automation Equipment, including: Pilot-Co-pilot arrangement on bridge with full ECDIS system for paperless navigation. The bridge equipment and layout is specified for a NAUT-AW class notation i.e. with a possibility to run with One Man Bridge Operation. Since this option is at present not possible the Class notation has not been included in the Certification, but all the safety enhancing equipment is in place. C-band SEVSAT satellite communication always online "broadband" solution giving internet and e-mail access to all crewmembers as well as efficient communication to/from shore based offices.
