A recent study from DNV indicates that there has been an increase in anchor related incidents. The chart below shows the trend over the last 6 years. The Swedish Club and GARD also show rising numbers of claims due to anchor incidents and losses. So, what causes these incidents and how can we help prevent them?
*The above chart was obtained from a webinar on the topic “Anchoring losses on a negative trend – how to improve?” This webinar was a joint webinar from DNV, Gard and The Swedish Club
Bad Weather has been identified as the most prominent reason for anchor related incidents.
The various incident investigations conducted by DNV, highlight that hesitation or delay in decision making has led to:
There can be various dangers and consequences due to anchor loss and anchor dragging incidents. Direct consequences include anchor replacement, recovery cost, off hire and service delays. Indirectly, it may also cause ship grounding, collision, damaged subsea equipment – including pipelines and cables, oil spills and more.
Potential Anchor dragging observed has been added to the notification library for various ships. Since this addition, SMARTShip has been able to provide advanced notifications to various ships enabling safer navigation.
This type of notification was developed by incorporating the below logic:
The vessel concerned is a newly built Oil/Chemical Tanker. Its carrying capacity is around 77,500 t DWT. Its length overall (LOA) is 228 meters and its width is 38 meters. The vessel was doing a series of short voyages along the various coastal cities of The Philippines during the month of July, 2021 and has been at anchorage near Zamboanga.
SMARTNotifications “Potential Anchor Dragging” activated on 12/07/2021 at 0238 UTC
The SMARTShip™ System detected the speed (SOG) of the vessel was greater than that of 1 NM while the ship was at anchorage.
Upon further analysis, it was found that Ship had traveled from the ship’s anchored position to 0.19 nm while its swinging circle radius is 0.15 nm. The system also detected that the ship’s speed over ground was also higher than that of the defined threshold of 0.3kn. Hence SMARTShip triggered the alert. Other parameters like ME RPM, STW etc were also plotted to analyze the data.
After the Master received the alert in the SMARTShip portal, he reviewed the same in ECDIS, which further confirmed that the ship had dragged from its original anchored position. The below screenshot shows the Vessel status during the anchorage.
The above use cases demonstrate how ships equipped with the SMARTShip platform and SMARTNotifications application, have contributed to a reduction in navigational incidents that detect any anomaly to normal behavioral trends and provide leading indicators.
With SMART Notifications, vessel operators, charterers and other maritime executives have real-time access to ship operations providing instantaneous value realization to all stakeholders through integrated insights, transparency, and enhanced collaboration. The initiative has led to a reduction of incidents onboard the ship. We have experienced over 100+ reported use cases in the below categories:
THE BENEFITS OF SMART NOTIFICATION ARE LIMITLESS.
To summarize, with SMART Notifications users have:
The ability to receive SMART Notifications through the SMARTShip Go mobile application is an added benefit for the user. This ensures that safety and compliance of the vessel is maintained through-out the year and at any given point of time.
