unit. ABB also delivered the main switchboard, propulsion transformers, two high voltage distribution transformers, propulsion control and remote control systems. The 750kVA harbour generator set and the 415kVA emergency generator are supplied by Volvo. The contractual icebreaking capability of Norilskiy Nickel was to be able to proceed with a minimum continuous speed of two knots in 1.5 m solid ice, with a snow layer of 200 mm, moving with stern first. According to reports from the ice trials, the icebreaking performance exceeded expectations. The vessel was able to break solid 1.5 m thick ice with a speed of almost four knots and penetrate rubble ice fields with a ridge height of three metres without charging, with an average speed of two knots. A three metres ridge height indicates a dept of some 30 m. The ship has an open water service speed of 15.5 knots. The navigation equipment is supplied by Kelvin Hughes. The ship has also an online information terminal for receiving information on the ice conditions and the ice cover along the ship's course. The Damatic/Valmarin-type machinery control and monitoring system is supplied by L-3 Communications Corporation. There is one free-fall lifeboat supplied by Ernst Hatecke GmbH, with a capacity of 25 persons, launched over the stern, and a rescue boat from the same supplier, in addition to needed liferafts. The mooring system and deck winches are supplied by SECGroningen B.V. The cargo part of the hull, forward of the engine room bulkhead, was built by Aker Yards in Warnemünde, Germany, and the assembly and outfitting took place at the Aker Helsinki yard. Norilskiy Nickel carries Russian flag with Murmansk as home port. The ship is built to Russian Maritime Register of Shipping ice class LU7, except for the stern of the vessel Cosco Guangzhou that will be built to LU6 BOW class RULES, which are more demanding than LU7 requirements for a stern would have been. The bow of Norilskiy Nickel is shaped for icebreaking too, and is not fitted with a bulb. The 9,500 TEU class containership Cosco Guangzhou built at Hyundai Heavy Industries (HHI) was delivered to Costamare, Greece on February 23, 2006. The vessel measures 1151.5 x 140.4 (351 x 42.8 m) with a 89.5 ft. (27.3 m) depth and design draft of 42.6 ft. (13 m). She is powered by a Hyundai-B&W 12K98MC (Mark 7) diesel engine, which develops an MCR of 74,760 kW at 97 rpm which enables the ship to sail at a service speed of 25.4 knots with 15 percent sea margin without power take off. The Hyundai containership features a wide beam, designed to ensure better stability when loading and unloading at international container terminals. It is also designed to have superior propulsion efficiency against the various draft which will be caused by loading scheme. The vessel has 10 holds, eight of which are arranged forward Maersk Qatar of the engine room (20 ft. container/32 bay) and two are backward (20 ft. container/8 bay) and a maximum of 15 rows and 10 tiers of containers can be stowed in the holds. Two air changes per hour are provided to No. 15, 9 and 10 hold in which dangerous cargoes of SOLAS classes 1 to 9 can be carried. The containership can carry the maximum 15 rows in holds and 17 rows on deck of containers. Total TEU capacity is 9,469 of which 4,673 TEU in holds and 4,796 TEU on deck, with 700 FEU reefer sockets provided. Pontoon type Al Marrouna hatch covers close the 10 holds. Each hatch cover is made up of three panels with maximum panel weights kept below 41 tons to suit handling by port cranes. The vessel is arranged to carry 20 ft.; 40 ft.; 45 ft. containers and cargo holds are provided with 40 ft. fixed cell guide. Athwartship lashing bridges are arranged with necessary fittings so that containers on hatch cover/stool on upper deck can be conveniently and securely lashed. The Hyundai containership is provided with both optimum section profile of rudder and tipraked propeller to reduce the possible cavitation. For durability of outside shell, tin-free self-polishing anti-fouling paint and ICCP is applied to the vessel. The vessel is classed and registered as GL +100A5, Container Ship, IW, SOLAS II-2 REG. 19, RCP(700/65), ENVIORONMENTAL PASSPORT, +MC, AUT. Gas Carriers Maersk Qatar, built by Samsung Heavy Industries for A.P. Moller, is a high quality LNG Carrier that has LNG cargo carrying capacity of 145,600 cu. m. Among 19 same-size vessels, seven are currently under construction and 12 have been delivered by the shipyard. The ship features the GTT Membrane Mark-III containment system, and was built for A.P. Moller for RasGas project. The vessel measures 928.5 ft. x 142.4 ft. (283 x 43.4 m) with a 37.4 ft. (11.4 m) design draft. It can carry 145,600 cu. m. of LNG with boil-off rate to 0.15 percent of the total cargo volume per day. This ship has a service speed of 20 knots at designed draft, driven by a Kawasaki Heavy Industries UA400 type steam tur- bine. Two 1,700 cu. m./hr. cargo pumps can be used to completely discharge the cargo tanks within 12 hours after the tanks have been pre-cooled by LNG spray. The ship has a bunker capacity sufficient for the cruising of 13,000 nautical miles on fuel oil only. The bunker tanks are surrounded for its protection by the water ballast tanks. The LNG Carrier Al Marrouna was built in Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME) OKPO shipyard for Teekay Shipping Ltd. under the survey of Lloyd's Register with the notation of +100A1, Liquefied Gas Tanker, Ship type 2G, Methane in Membrane tanks, Maximum Vapor Pressure 0.25 bar, Minimum Temperature minus 163 oC, ShipRight (SDA plus), *IWS, LI" "+LMC, UMS, NAV1, IBS, ICC" with descriptive notes "ShipRight (PCWBT, FDA plus, CM, SEA(HSS-4L, VDR), SCM, TCM, PMS(CM)), ETA". The ship, which measures 945.5 x 142.4 ft. (288.2 x 43.4 m) with an 85.3ft. (26 m) depth and a 39.4-ft. design draft -- is designed to transport 151,700 cu. m. of liquefied natural gas at one time, meaning that it has 3,400 cu. m. more cargo capacity than existing NO96 type LNG carriers with same principal dimension. Powered by a marine steam turbine which generates 36,800 ps, the ship is able to sail approximately 16,000 nautical miles without using of any boiloff gas. With the assistances of an innovative hull form, the ship can achieve 20.5 knots at the draft of 12 m on even keel with the main steam turbine at 90 percent MCR (33,120 PS) without sea margin. Design fatigue life of critical details and all longitudinal stiffener connections to transverse webs and transverse bulkheads is minimum 40 years based on the North Atlantic trading route (UK South West Approached to Boston USA, great circle route).
