A game changer
How green should your container ship be? How big should it be? Will the new 18,000TEU container ships change the business in the future?
First 2-stroke gas engine taking Quantum 1-stroke further
MAN/DNV joint press conference in London: By introducing a new solution for LNG-fuelled ships, DNV and MAN Diesel & Turbo are taking the Quantum concept ship one stroke further. Both the machinery and the hull design and arrangement have been improved.
Concept overview
Quantum 9000 has been designed to be more efficient and environmentally friendly than existing ships without introducing major complications in the building and operation of the ship.
Hull design and arrangement
The hull design and arrangement have been optimised to allow maximum space utilisation, minimum hull fuel consumption, minimum need for ballast water and increased safety.
Handling LNG safety
The main safety challenges concerning the use of LNG as fuel are related to the explosion risk, extremely low temperatures and tank location.
APL kicks off an aggressive container newbuilding programme
“We need to speed up the growth of our fleet to maintain a strong position in the container market,” says Captain Tey Yoh Huat, APL’s Vice President, Technical Services, in an interview with Container Update. The Singapore-based global container operator announced it had ordered a series of newbuildings in 2010. “Fleet growth is necessary to keep up with the market. Economy of scale is crucial in this business,” says Captain Tey.
Cost efficient and reliable container ship operation
How can class contribute to cost-efficient and reliable container ship operation? It is about sharing knowledge, making it available to seagoing officers and helping the company to better look after the ship’s hull and structure. DNV is now introducing a new survey arrangement for container ships. It is based on the experience gained from running pilot schemes with two highly reputable container ship managers for seven years.
Controlling ballast water convention risks
The International Convention for the Control and Management of Ships’ Ballast Water and Sediments is one of the most significant environmental and operational challenges faced by the maritime industry today. Once it enters into force, the Convention will require compliance by all ships and offshore structures designed to carry ballast water, regardless of their age or size.
Energy Efficiency Design Index consequences for container shipping
The IMO Energy Efficiency Design Index is a benchmarking scheme and an indication of a merchant ship’s CO2 output in relation to its value for society.
LNG offers best economic performance
DNV has established economic models for the above mentioned three solutions for meeting the ECA requirements.
LNG offers best impact on local environment
Of the three options for meeting the ECA requirements, LNG fuel has the lowest emission of all three local pollutants NOx, SOx, and particles, as well as the global green house gas CO2: NOx emissions are reduced by 85–90%, SOx and particles by close to 100%, and net GHG emissions by 15–20%.
Latest IMO regulatory developments relating to GHG, SOx and NOx emissions
IMO’s work on measures to enhance ships’ energy efficiency and thereby control and reduce their greenhouse gas emissions has three distinct ‘building blocks’, the Energy Efficiency Design Index (EEDI), Ship Energy Efficiency Management Plan (SEEMP) and Market Based Measures (MBM).
Boxship rates resist the seasonal downturn
Containership timecharter rates developed positively in the 2nd half of 2010. The recovery of the demand for boxships proved to be surprisingly strong throughout the year, losing stamina only slightly in the 4th quarter.
