Newbuildings Danes design
Saudi con-ro’s Te National Shipping Company of Saudi Arabia (NSCSA) and South Korea’s Hyundai Mipo yard signed a contract for four container/ro-ro (con-ro) ships of 26,000dwt with options for a further two vessels. Danish ship designer Knud E. Hansen said that it
“carried out a very thorough project study including design and calculations” and assisted NSCSA in the contract phase of the deal by providing technical expertise and advice. The ships are designed to allow flexibility in
loading both ro-ro and container cargo and with a focus on low fuel consumption. In order to minimise turn around time in port the vessels are designed with good manoeuvrability and optimised cargo decks.
guidelines for LNG carriers and Offshore Floating Production Units (FPUs) after signing a three-year co-operation agreement. Common guidelines for LNG carriers based on the
class societies’ rules and GAP analyses carried out by the societies are expected to be published during the first three months of next year while work on producing common guidelines for FPU’s is expected to begin in the second half of this year. Pierre Besse, vice-president
research and
development for BV, said: “We will now be able to combine the particular strengths of the BV and RS rules, to produce definitive guidelines which draw on the experience and expertise of both organisations. In addition, the co-operation agreement enables us to exchange information from the results of recent research projects, including those relating – but by no means limited - to operations in Arctic conditions.”
Engines Wärtsilä Upgrades
RT-flex68-D The first upgraded Wärtsilä RT-flex68-D engine
equipped with a variable turbine geometry (VTG) turbocharger was successfully tested at Doosan Engine Co Ltd in South Korea. It is fully compliant with the International Maritime Organization’s (IMO) Tier II regulations. Its slimmer outline of the RT-flex68-D makes

general and project cargo sectors, with a focus on service between the United States East Coast and the Middle East (Red Sea-Arabian Gulf) and the Indian Subcontinent. Te first vessels will replace NSCSA’s aging con-ro

it more suitable for installation on container ships and the company said the engine provides extended flexibility over a broader load range when equipped with a VTG turbocharger. Te tested engine is the first of eight for installation on eight vessels being built by a Chinese shipyard for a Chinese owner. Te engine has a contracted maximum continuous power of 21,910 kW at 95rpm. The slimmer engine outline was achieved by
space for ro-ro cargo. Te
amin engine will have a maximum continuous rating of 12,500kW giving the ships a service speed of around 17knots. Te ships will be 220m in length, have a beam of 32.3m and a maximum draught 9.5m.
Classification BV and RS in sign 8
LNG/FPU deal France’s Bureau Veritas (BV) and the Russian Maritime Register of Shipping (RS) have agreed to jointly develop
introducing a simplified supply unit and a new design for the scavenge air receiver, as well as RT-flex components which offer improved engine maintenance due to the greater commonality of parts with other engine types which reduces both component costs and the spares inventory. Components were also made more manufacturing-friendly. The RT-flex electronic control system, in
combination with the VTG turbocharger, enables more efficient operation and a better brake specific fuel consumption (BSFC) over an extended load range allowing the engine to meet IMO Tier II emission regulations while maintaining a highly competitive fuel consumption. “With this development, Wärtsilä is able to offer
a technological solution for lowering emission levels The Naval Architect April 2011
