Lessons learned: Collision during ‘starboard-to-starboard’ passing

In its Loss prevention – Navigational claims publication, the Swedish Club describes a collision between two vessels in a narrow channel. In this case, while there was a verbal agreement to pass ‘starboard-to-starboard’, one of the two vessels did not maintain position on its starboard side of the fairway.

The incident

Vessel A, a capesize bulk carrier, was approaching port while fully loaded with iron ore.

The water depth in the fairway of the port was more than 18 metres. However, the water...

Japanese partners to study collision avoidance algorithms

Japanese shipping company MOL announced a joint study with three com-patriot partners on collision avoidance algorithms and autonomous collision avoidance. The study, to be named ‘Focus Brain’ is aspiring the development of Artificial Intelligence for autonomous navigation.

The company, along with MOL Marine; the National Maritime Research Institute of National Institute of Maritime, Port and Aviation Technology; and Tokyo University of Marine Science and Technology, have signed a contract to...

Non compliance with COLREGs could lead to collision

In it’s latest issue, CHIRP focuses on two vessels’s crossing situation, while approaching a major port, as one of them didn’t follow the 15th rule of Collision Regulations. With a CPA of less than 0.25nm between the vessels, the report describes the whole procedure that each ship made and the actions taken, in order to avoid an incident.

In this report, CHIRP received a message about two powered-driven vessels passing through a crossing situation. Specifically, the vessel (A) was proceeding...

Fujitsu, MPA Singapore trial AI ship collision prediction technology

Fujitsu announced the results of a field trial that was conducted with the help of the Maritime and Port Authority of Singapore (MPA). This trial analyzed marine traffic risks in the Singapore Strait, with Fujitsu presenting the usefulness of a new ship collision risk prediction technology.

This new technology leverages the power of Artificial Intelligence (AI) in predicting near misses between vessels.

Ship contacts wharf as harbour master, pilot are unaware of fender issues

ATSB published its report on the contact with a wharf by the livestock carrier Angus Express. The vessel contacted Berths 4 and 5, at Broome, Western Australia, on 20 April 2018. The report concluded that the harbour master and pilot were not aware of any height of tide limitations regarding berthing ships alongside Yokohama fenders at these berths.

The incident

On 20 April 2018, the 103 m livestock carrier Angus Express arrived at the Broome, Western Australia, pilot boarding ground. The ship...

Watch: How the HiLo model works

This video explains how the HiLo model works. HiLo prioritizes based on risk. The model has analyzed thousands of maritime industry accidents and then calculates the probabilities of leading events, causing undesired events.

Traditionally, maritime organizations plan safety campaigns by assessing the number of times accidents have happened. They then prioritize from the the highest number of occurrences to the lowest.

NTSB: Distractions, fatigue among the main problems for shipping

The US National Transportation Safety Board (NTSB) announced its 2019 – 2020 Most Wanted List of Transportation Safety Improvements, during an event held at the National Press Club, on February 4. The list includes 10 improvements, of which two regard shipping as well: eliminate distractions; and reduce fatigue-related accidents.

The 2019 – 2020 Most Wanted List advocates for 46 safety recommendations that can and should be implemented during these next two years, NTSB Chairman Robert Sumwalt,...

MOL uses algorithm to improve collision avoidance

MOL announced that MOL Techno-Trade, the National Maritime Research Institute (NMRI), and Tokyo University of Marine Science and Technology (TUMSAT) carried out an assessment and feasibility study on advanced navigation support systems, using the NMRI-owned ship handling risk simulator.

On watch-keeping, mariners must be able to see an object and judge if it poses a risk. If it does, the vessel must take some action to avoid the risk, such as veering, slow steaming, and so on. The “Obstacle Zone...

Collision liability and autonomous ships

As autonomous shipping is gaining more and more ground, it is contended that the present fault-based collision liability regimes of most jurisdictions do not sufficiently cater for the situations that may arise, highlights Lina Wiedenbach, Lawyer at Arnecke Sibeth Dabelstein, IUMI Professional Partner, who noted that the traditional means of establishing fault will be affected by how the human actions or omissions will move further away from the collision in time and space. This is expected to...

Ship collision risk increases as China sees more fishery farms

Several marine incidents in China have been reported involving merchant vessels colliding with fishery farms, mostly off the coast of Lanshan and Rizhao areas where mussel and oyster cultivation form the bulk of aquaculture industry. Huatai Insurance Agency handled overall 71 fishery farm entry claims in China through 2017.

In this regard, Siddharth Mahajan, Loss Prevention Executive at Gard P&I Club, in cooperation with Huatai Insurance Agency, Wang Jing & Co. and Worldwide Maritime...
