Great Ships of the Year
Name Tempera Type Double Acting Tanker (DAT) Owner Fortum Built Sumitomo Heavy Ind.
Kvaerner Masa-Yards is well renowned for its ship and ship's equipment ice breaking technology.
Upon visiting Finland on a recent excursion and enjoying winter in November, it's easy to see why. Quite simply, Finland must keep its icy shipping channels open during the winter to ensure its commercial survival. In the beginning of the 1990s, the company, in partnership with the Finnish Maritime Administration and ABB Industry of Finland, developed a new electrical propulsion system for icebreakers, the trade name of which is Azipod. The first vessels equipped with the new system, the 16,000 dwt tankers M/T Uikku and M/T Lunni owned by Fortum operated Nemarc Shipping, have now, combined, nearly 100,000 hours of operation experience, and the vessels have, for example, several times successfully navigated through the North-East Passage in extremely harsh conditions.
Through real world experience and continuous R&D, the shipyard has shown that vessels with a podded drive are capable of breaking ice with a considerably higher efficiency than before, when moving backwards with the propeller first.
This concept — DAT — was developed by Kvaerner Masa- Yards, and now its first reference is in service. The 105,000 dwt M/T Tempera, built in Japan for Fortum Shipping, has arrived to its home waters for the first time, as well as M/T Mastera that will be completed later, are the first cargo ships of this double-acting type in the world. In open water, they can reach a speed of 17 knots, and thanks to their efficient icebreaking capacity that can be achieved while running with stern first, they are entitled to the highest IA Super Ice Class with their engine power of 16 MW, while even 25 MW would be required for this, using conventional technology. These vessels are able to navigate independently in the Baltic Sea area. M/T Tempera was built at the Yokosuka shipyard of Sumitomo Heavy Industries Ltd.
in close co-operation with Kvaerner Masa-Yards under license by the latter company.

Name Rickmers Hamburg Type Multipurp. Container Carrier Owner Rickmers Linie Builder Xiamen Shipyard Combining a specialization in project and heavy-lift freight with long experience in liner-type service, Hamburg-based Rickmers- Linie has opened a major new stage of fleet development entailing nine ships of the Superflex Heavy MPC (multipurpose container carrier) designation.
Name Hurst Point Type RoRo Ferry Owner DFDS Builder Flensburger Schiffbau GesellSchaft (FSG) Flensburger Schiffbau- Gesellschaft (FSG) has developed a future generation of RoRo ferries incorporating a capacity for 6,000 lane-m of freight.
FSG delivered the 722-ft. (220- m) Hurst Point, the first of four 23,300-gt RoRo sisters contracted by British consortium AWSR for strategic sealift duties under a transport service agreement with the U.K. Ministry of Defense. The 2,600 lane-m heavily-reinforced design incorporates three decks, with the addition of a 36-ton crane on the weatherdeck, and further demonstrates the German yard's propensity for meeting bespoke RoRo requirements within the bounds of efficient production practices. The vessel series, which has already attracted the interest of operators looking to achieve further scale economies on highvolume routes, combines an unprecedented arrangement of five trailer decks and flexible freight distribution with a rapid service speed of 23-knots. The design thereby promises high productivity as well as a major advance in unit capacity. Close attention to hull form, hydrodynamic performance and propulsive plant configuration has resulted in an attractive speed and power relationship, bearing on freight ton-mile efficiency and also capital outlay. The favored layout keeps faith with the dieselmechanical concept, comprising four medium-speed engines driving twin controllable pitch propellers through reduction gearing.
The engine written into the provisional specification is a sevencylinder version of the MaK M43 series from Caterpillar Motoren, for a total plant output of 25,200- kW. The 6,052 lane-m design from Flensburg could be the next trendsetter. The as yet unique provision of five decks suited to trailer- borne freight comprises four enclosed decks plus the weather deck, served by an inter-deck ramp system configured to allow simultaneous working of four different cargo areas. RoRo access is concentrated over twin stern ramps.
First-of-class Rickmers Hamburg is every inch the modern maid-of-all-work, offering a 640-ton unit lift capacity along with a variable hold space configuration suited to the widest range of breakbulk and conventional cargoes as well as large, indivisible items of freight. The 30,000-dwt Superflex series is due to extend to nine ships before the end of next year, with construction having been distributed among three yards in China.
The Rickmers-Linie program entails five vessels from Xiamen Shipyard and two from Jinling Shipyard, plus the Rickmers Hamburg and a sistership from Shanghai Shipyard.
The five-hold design is fitted with four, high-stooled deck cranes, two of which have a 320-ton maximum lift capacity, while one is rated at 100-tons and other at 45-tons.
By using the two largest units in tandem, piece weights up to 640-tons can be handled.
The hatchway layout provides openings up to 105 ft. (32 m) in length and 34 ft. (10.3 m), accessing holds fitted with adjustable tweendecks. The below-deck arrangements mean that the hold spaces can be highly compartmentalized using three flexible tweendecks, or can be configured to give various hold heights up to 15.7-m in accordance with cargo needs, making for optimum space utilization.
N a m e Harad Type VLCC Owner Hellespont Builder Samsung Heavy Industries Harad is the first in a four-ship doublehulled series of VLCCs constructed for Hellespont of Greece by the South Korean builder Samsung Heavy Industries. During construction, the four vessels were re-sold to NSCSA of Saudi Arabia. The vessel, which incorporates a number of technical features to ensure high levels of environmental protection and high performance, holds a large main engine, improved strength by increased plate thickness, improved service lifetime for coatings by increased paint specification and advanced inert gas system.
The hull form of the vessel has been specifically remolded to meet Hellespont's requirements and differs from the conventional VLCCs, featuring a 'blunt' fore part and a breadth of 190 ft. (58 m) to reduce hull deflection. As a result Harad benefits from a reduction in hull deformation by around 10 percent. This has been achieved by strengthening the primary member, double structures and buttress. The hull structure has been designed in accordance with the requirements of ABS Safehull and LR' ShipRight, with a structural quality maintained with the usage of higher tensile steel to 45 percent of the total hull structural steel weight. In addition Z quality steel were used for outermost strake in the inner bottom and 'E' grade steel in the lowest hopper strake.
The number of individual components within the hull structures and the size of the painting area in the water ballast area have been reduced by using a construction method based on one internal bottom plate for each block. According to the shipyard, this reduces the number of maintenance points onboard the vessel. Local strength requirement means that the bottom longitudinal stiffener of the cargo well has to be 18 mm thick compared with conventional VLCCs, which tend to be 12 mm. This approach virtually eliminates the possibility of welding defects and subsequent paint damage since there is no welding seam.
HARAD is powered by an Samsung Wartsila NSD 8RTA84T-D engine developing (MCR) 33,300 kW (44,640 bhp) at 76 rpm.
The service speed is 16.1 knots at main engine output of 26,780 kW (35,900 bhp) including 15 percent power margin. The main engine operates on heavy fuel oil with a maximum viscosity of 700cSt at 50°C. The large power main engine enables considerably higher speed when utilizing the NCR of the engine.
The ship has a total of 15 cargo oil tanks with a combined capacity of 342,510 cu. m.
at 98 percent loading. In addition, there are two slop tanks fully coated in tar epoxy with a capacity of 7,030 cu. m.. The cargo pumping system allows for a maximum discharge rate of 15,000 cu. m./hr. at a head of 160 mlc via three main pumps. The maximum loading rate is 20,000 cu. m./hr. Three grades of oil can be handled simultaneously through a two-valve segregation arrangement.
The ship is outfitted with an inert gas system with double scrubbers, which reduces the S 0 2 content to less than 2 ppm.
