Classification society ClassNK has announced it will begin a joint research project aimed at improving safety standards for ultra-large container ships.

To ensure the smooth adoption of thicker steel in the industry, ClassNK has embarked on developing technical standards in order to clarify the crack arrest parameter for brittle crack arrest steel plates exceeding 80mm in thickness. It aims to create clear evaluation methods in a proposal it will submit for the unified IACS requirements.

The project will be carried out as part of the ClassNK Joint R&D for Industry Program in collaboration with the Japanese Welding Engineering Society (JWES), steel manufacturers, shipbuilders,

Safety at sea IDX15D1





Austrian communications and information systems house Frequentis (Stand A-040) is giving a public debut to its new ICM (Incident and Crisis Management) system at NAVDEX 2015. ICM organises and automates emergency management procedures to support operators in their decision-making process, and so improve the speed and efficiency of responses. The system integrates into existing maritime communications and information systems.

ICM guides operators through approved emergency management procedures, collating and displaying incident-related information automatically, and identifying key contacts and assigned responsibilities.

According to Frequentis, “These contacts and relevant deployment resources receive automated alerts and information updates, helping to ensure a faster and more informed incident response.”

A particular feature of ICM is the user interface, designed in collaboration with experienced operators.

The Australian Federal Police have arrested the captain of a Chinese coal ship for sailing through part of the Great Barrier Reef Marine Park without a pilot.

The ABC understands the captain — a Taiwanese national by the name of Lu — will plead guilty to a charge of being the master of a ship without a pilot in the marine park, an offence that carries a maximum fine of $85,000.

It is alleged the bulk carrier, the China Steel Developer, left the port of Mackay on New Year's Day and sailed through Hydrographers Passage, a deep water channel near Creal Reef off Mackay, without

The Sealite PEL installed at a major Australian port

Sealite has introduced a new 5 degree LED Sectored Port Entry Light, which provides an overall 5 degree beam width and over 500,000cd of lighting power at only 30watts electrical consumption.

The PEL has a night-time visible range of over 23NM and day-time visible range of over 5NM, and is designed specifically to suit high-precision sector applications with a typical measured changeover between colour sectors of one minute of arc.

The LEDs can be configured for automatic night time dimming to eliminate the requirement for moving filters, and can also be individually flashed to reduce the need

Under Coldharbour Marine's system, gas lift diffusion (GLD) units stir inert gas into the ballast water

There are options beyond UV and electrochlorination for ballast water treatment systems, as Coldharbour Marine's inert gas system shows. CEO Andrew Marshall discusses the thinking behind the technology, and the challenges any BWT system faces, in The Motorship's February issue.

It is likely that the IMO Ballast Water Management Convention will come into force this year or early 2016. There will be many a furrowed brow as owners, operators and agents decide exactly which system is best for their fleet.

Before Coldharbour Marine designed its ballast water treatment (BMT)
