Aero-Citadel by Imabari Shipbuilding

Imabari Shipbuilding has developed the Aero-Citadel, a newly designed superstructure which brings to realization both energy efficiency and anti-piracy measures.

Energy efficiency 

The Aero-Citadel is a superstructure with slimly streamlined shape which combines ship’s accommodation, engine room , and funnel casing. Wind pressure during navigation will be reduced by 25-30% (as the result of the wind tunnel testing). In case of Cape size bulk carrier, it will enable a decrease of about 2% in fuel consumption (at normal output, about 9m/sec. – Beaufort 5 head wind). New marine use LED lighting is also introduced to the accommodation and engine room lighting system, which reduces electric power consumption used for lighting by about 50%.

NOAA’s New Alaska Navigational Chart

NOAA presented on 22/05/2012 to Alaska officials a new nautical chart for Kotzebue Sound in the Alaskan Arctic, a sparsely charted region that is seeing increased vessel traffic because of the significant loss of summer sea ice.

The new chart depicts the full range of depth measurements and object detection acquired during a full ocean bottom survey last summer by the NOAA hydrographic survey ship Fairweather. It replaces a chart showing depth measurements last taken in the 19th century spaced three to five miles apart, leaving room for possible undetected dangers in between.

Guidance for PMSC Agreed by IMO’s Maritime Safety Committee

Interim guidance to private maritime security companies (PMSCs) was agreed by IMO’s Maritime Safety Committee (MSC), when it met at the Organization’s London Headquarters for its 90th session from 16 to 25 May 2012.

A special high-level segment of the MSC saw an intense debate, on how the international community should deal with issues related to the deployment of privately contracted armed security personnel (PCASP) on board ships and the carriage of arms on board.]

EU Provisional Agreement Regarding Marine Fuels Sulphur Content

The European Union has come to an agreement regarding draft legislation on marine fuels which aims in ensuring that all vessels operating in EU waters will reduce harmful emissions by adhering to sulphur content limits in marine fuels.

International Maritime Organization Main Instruments

One of the main aims of IMO is to ensure co-operation among maritime governments of the world. It also uses a number of instruments to implement and maintain the highest standards in areas of maritime safety, prevention of marine pollution, and shipping navigation and trade.

In this article, we will learn about 5 important instruments which IMO uses to ensure smooth operations at the sea, backed by highest standards of maritime safety.

The 5 important instruments of IMO are:

  1. Conventions
  2. Protocols
  3. Amendments
  4. Recommendations, codes, and guidelines
  5. Resolutions

Seafarer’s Health & Lifestyle

Physical and mental health problems amongst seafarers are not uncommon particularly if we consider the type and the difficulties of the work that a seafarer has to face onboard.

When thinking of seafarers’ health and lifestyle one should always have in mind just few of the following factors: ƒunstable work schedules and long working hours due to operational needs, the small community which one should adapt and work with, the feeling of being away from home and familiar faces, the difficult working environment as well as all the hazards that are involved, the restricted medical facilities and limited medical supplies, the confined nature of life on board ship, the climate of the area where the ship is operating.

All the above along with the come and go from home nature of the seafaring profession adds pressure to a person, even if he is not realizing it and is not helping in any way to maintain healthy behaviors like frequent exercise, normal sleep intervals, healthy living environment etc.

Oily Water Separators

The story so far

Oily Water Separators (OWS) are being used onboard ships as a regulatory requirement of MARPOL conventions. Their main use is to clear the water that has been accumulated in ship’s bilges and produce water that its contents is within acceptable limits in order to be discharged overboard.

OWS are mainly installed and used onboard to protect the environment and consequently the public interest. Therefore since they don’t produce any “measurable” profit for the ship owner and because they don’t play a critical role to the ship’s structural or operational safety, they don’t get the attention they should be given as a system.

Fishing Trawler Lost in Japan Tsunami Reaches Canada

According to Canadian officials, a 65-meter Japanese fishing boat that was lost more than a year ago in the tsunami, off the east coast of Japan, has been spotted  278 kilometers off the southern coast of Haida Gwaii islands, approximately 1,500 kilometers north of Vancouver. The “ghost ship” was spotted by a Canadian military air patrol, and it is believed that it has been adrift  since March of the last year.

“It looks fairly sound and has rust streak from being out there for a year,” said Marc Proulx, the maritime coordinator of the Joint Rescue Coordination Center in Victoria, British Columbia.

Reliability Theory of Structures

The marine industry can improve its performance in designing systems, subsystems and components on which its operations depend on by using risk-based methods and tools. In an environment of increasingly complex engineering systems and structures, the concern about the operational safety of the latter continues to play an important role in their design, construction and operation procedures. A rational and quantitative approach for assessing the failure probabilities and the impact of failure of the structure on its environment (human beings, natural environment) is needed. [Read more…]
