10 Maritime Reporter & Engineering News NEWS Evergreen Orders 10 Ships The Evergreen Group placed or- ders with Samsung Heavy Indus- tries for 10 8,000-TEU L-class environmentally advanced con- tainer ships. The first vessel is due for delivery in 2012 and will join Evergreen Line global container- ship fleet. Six of the new vessels will be built for Evergreen Marine Corporation and four for Ever- green International S.A. (Panama). The ships are being built at a cost of $103 million each. The new ships will be constructed under the innovative Greenship design con- cept developed by Evergreen Group Chairman Dr. Chang Yung- Fa nearly 10 years ago and first in- troduced in 2003. The features have been built into every Ever- green Line vessel since then. The Greenship program has taken en- vironmental protection and com- pliance to a superior level. With an overall length of 334.8 m (1100 ft) and a beam of 45.8 m (150 ft.), the new ships will have cruise speed of 24.5 knots. ABB Azipod: Performance in Harsh Environs ABB received an endorsement from two leading Russian cus- tomers on the performance of Azi- pod propulsion in the harshest environments in the marine sector. The impending fourth anniversary of the delivery of the ice breaking tug Polar Pevek has prompted the vessel’s technical management company OOO Polarus to offer its approval of Azipod propulsion technology as the “right choice” for extreme ice conditions. Deliv- ered by Aker Langsten in June 2006, the 940 dwt Polar Pevek is owned through the GC Rieber Shipping/Primorsk Shipping Corp joint venture Polar Pevek Ltd, reg- istered in Cyprus. The DnV Ice 10 IB offers 115 tons of bollard pull ahead, and 95 tons astern. At 74.6m long, the vessel features generators, main switchboard, propulsion drives and two 5 MW Azipod units, all of which have been supplied by ABB. Already operational in the Sakhalin field for the last five years has been Fesco Sakhalin, operated by Far East Shipping Company. The 3,950 dwt, DnV Ice 10 IB pro- vides a further endorsement of Azipod technology in ice condi- tions. Ocean Rig's semi-submersible drilling rig Leiv Eiriksson has navigated the Bosphorus Strait using the new DPS 4D Differential Positioning System developed by Kongsberg Maritime's specialist posi- tion reference and satellite positioning di- vision, Kongsberg Seatex. Leiv Eiriksson is one of the first vessels to apply DPS 4D, which uses the latest advances in GPS/GLONASS technology, aided by in- ertial technology using Kongsberg Sea- tex's new Motion Reference Unit, MRU 5+, to optimize signal tracking, integrity and availability for Dynamic Positioning (DP) applications under challenging GNSS conditions. Ocean Rig reports that DPS 4D provided continuous, accurate position data during the transit of the Bosphorus Strait, demonstrating integrity and availability of position data at all times. "The Bosphorus Strait is well rec- ognized as being a hazardous area for nav- igation,” said Stein Egil Svendsen, Marine Manager at Ocean Rig. “Despite the bridges and other obstacles, which actu- ally interrupted other satellite-based ref- erence systems onboard, we were able to reference our position continuously, only because we had DPS 4D. The availability of position data helps to improve safety and efficiency of operations and I'm con- fident that DPS 4D will enhance future navigation and maneuvering operations for Leiv Eiriksson." Kongsberg DPS 4D uses all available satellite navigation sig- nals by combining GPS/GLONASS and MRU 5+ into a single system. The MRU 5+ measurements effectively bridge gaps in the satellite signal caused by physical obstructions, ionospheric activity and shadowing from nearby objects which may reduce signal availability. RAIM (Re- ceiver Autonomous Integrity Monitoring) enhanced by data from MRU 5+ also pro- vides an assessment of the reliability of position and velocity data under challeng- ing GNSS conditions. DPS 4D is also de- signed to use all frequencies in systems available today as well as future GNSS signals and future global satellite naviga- tion systems such as Galileo. Kongsberg DPS 4D has an intuitive and easy to use Human Machine Interface (HMI) devel- oped in close co-operation with end-users. The primary goal of the HMI is to enable the operator to instantly identify and react safely to critical situations. Operators need to assess the quality of their position so user-defined visual presentation using multiple layers of information is available. DPS 4D Kongsberg Maritime Debuts new system in Houston Maersk Tankers, HHI & DNV Maersk Tankers, Hyundai Heavy Industries (HHI) and Det Norske Veritas (DNV) have agreed to collaborate on the design and risk assessment of tankers for shipping CO2. Maersk Tankers is already in a partner- ship with Maersk Oil and Finnish utilities Fortum and Teollisuuden Voima (TVO), aimed at developing a joint carbon emis- sions abatement project in the area of Car- bon Capture and Storage (CCS). “Shipping CO2 in tanker vessels is a cost effective and flexible way to get CO2 from power plants to offshore storage sites, which makes it a suitable solution for large CO2 emission sources such as coal-fired power plants, especially in the emerging phase of CCS.” said Anders Schulze, Head of CO2 Shipping in Maersk Tankers. Maersk Tankers and HHI already have the initial blueprints to build tanker ves- sels for the transport of CO2 from emis- sion sources to storage sites. The vessels will be semi-pressurised and semi-refrig- erated, keeping the CO2 liquid. HHI has designed the vessels together with Maersk Tankers, based on years of experience with transportation of liquefied petro- chemicals and natural gas, and in accor- dance with global standards. “The further development of the CO2 carrier design shall mainly focus on the safety and the Green ship requirements while emphasising the high energy effi- ciency of the vessel. HHI’s technical co- operation with Maersk Tankers and DNV explains well HHI’s policy of constant pursuit of new technology and also its dedication to finding solutions to the en- vironmental issues in the shipbuilding segment.” says Mr. Jae Keun Ha, Senior Vice President of HHI. DNV will provide feasibility studies, risk identification in addition to general support for compliance with applicable class Rules and the current Gas Carrier Code as well as its latest developments specifying CO2 in more detail. These tasks will also include evaluations and support to ensure that the vessel is fit for purpose and fits well into the specific CCS chain. “The overall technical features of these CO2 carriers have similarities with LPG carriers and offshore shuttle tankers. Many of the applicable safety standards to be applied are therefore basically well known. Studies will, however, have to be carried out to ensure that all features and specialities have been adequately ad- dressed and that the vessels’ interface with the rest of the CCS chain is in harmony with the intentions.” says Jan Koren, DNV’s Segment Director Tankers.
