Tackling the issue of underwater noise

Korean Register issues guidance to help the marine industry tackle underwater radiated noise from ships.

The Korean Register (KR) has issued new class notation and guidance to help the marine industry tackle noise from ships.

“Several countries and ports have already introduced regulations relating to underwater radiated noise and some ports, such as the Port of Vancouver, are offering discounts on port user fees for vessels that meet the standards,” said a KR official.

”If our customers’ vessels have obtained KR’s class notation for underwater radiated noise, they will also be able to benefit from these advantages while reducing their impact on the maritime environment.” Continue reading “Tackling the issue of underwater noise”

A Transport Accident Investigation Commission (TAIC) report reveals that the Singapore-flagged ship Funing had been unable to generate full power because a fuel injector control unit (ICU) had suffered fuel leakage and become clogged with coking debris from the use of low-viscosity low-sulphur fuel.

On 5 July 2020, the log carrier Funing finished loading its cargo at the Port of Tauranga and began preparations for departure. At about 2200 the officer of the watch contacted the engineers and informed them that departure was planned for midnight. When the main engine was tested in the astern direction, the main engine fault log indicated there was a fuel injection quantity piston failure. The engineering team attempted to rectify the fault but were unable to before the vessel departed its berth at about 0018, when the fault reoccurred again Continue reading “Engine fault due to effect of low-sulphur fuel on injection control unit says report”

Annual Shipping Industry Flag State Performance Table published by the International Chamber of Shipping

Shipping Industry Flag State Performance Table 2021/2022 released by ICS
Shipping Industry Flag State Performance Table 2021/2022 released by ICS

The annual Shipping Industry Flag State Performance Table 2021/2022, from the International Chamber of Shipping, has identified reporting on seafarer wellbeing as a “casualty of the pandemic,” following its publication.

The Table is intended to encourage shipowners to maintain a dialogue with their Flag states, and help facilitate necessary improvements in the interests of safety, the environment and decent working conditions, among other issues. The Flag State of a merchant ship is the jurisdiction under whose laws the ship is registered or licensed and is deemed the nationality of the vessel.

This year’s Shipping Industry Flag State Performance Table highlights a drop in levels of reporting on the status of national ILO labour Continue reading “Annual Shipping Industry Flag State Performance Table published by the International Chamber of Shipping”

Using remote survey techniques to augment shipyard surveys being examined

A pioneering joint development project (JDP) between ABS and Nakilat – Keppel Offshore & Marine Ltd. (N-KOM) will examine how techniques developed by ABS for its industry-leading program of remote survey of vessels in service can be applied to surveys and inspections in the shipyard.

Remote inspection technologies will be applied to six Class surveys for this trial, to test how they can then be used to verify the required survey or inspection by ABS Surveyors to optimize scheduling and minimize downtime for both the shipyard, vessels and ABS.

The JDP will examine how remote techniques can be carried out on rudder clearance inspection; stern tube weardown inspection; rudder Continue reading “Using remote survey techniques to augment shipyard surveys being examined”

The purpose and limitations of silver nitrate testing

Silver nitrate testing should be seen only as a means of establishing the presence of chlorides
Silver nitrate testing should be seen only as a means of establishing the presence of chlorides. Image for illustrative purposes only.

Silver nitrate testing is carried out to detect the type of halide ion in a given solution. Steel products such as coils of rolled steel sheet, billets, tubes and steel plate are routinely presented for shipment at sea. The hot rolled steel products can at times be transported to outside shore storage and transit sheds without the provision of a covering or protection from the elements.

Steel products can be high value cargo that is susceptible to contamination from chlorides which are corrosive. Contamination from chlorides can occur at any stage of the transportation and storage process following production. Unfortunately, it is generally only during sea transportation that claims will be brought forward for alleged “seawater wetting” as it is an easy allegation that the contamination has Continue reading “The purpose and limitations of silver nitrate testing”

Corrosion of tank containers’ inner surface now the main cause of claims says TT Club

The main cause of claims is from corrosion of tank containers’ inner surface
The main cause of claims is from corrosion of tank containers’ inner surface

TT Club’s analysis of 2020 claims points to an increase in impact related incidents, with corrosion of tank containers’ inner surface and contamination caused by cargoes previously carried as significant other causes of loss.

The analysis makes clear that the effects of increased volumes of tank containers used to trade chemicals and other liquids on the primary east-west trades have altered, to a degree, the risk profile of damage to such units. While in previous years there has been a consistent dominance of contamination as the major source of losses for tank container operators, the current figures show impact incidents as the foremost causation.

Almost two years after the containership APL England lost containers overboard in a storm, a court in Brisbane has entered formal charges against the captain clearing the way for a trial to proceed. The prosecutor failed to make the case for one set of charges against the captain for pollution but the court agreed he should face charges of operating the ship in an unseaworthy condition. The charges were filed against the captain while the Australian Transportation Safety Bureau continues its investigation and is yet to release a final report on the incident.

The importance of verifying wire rope terminations

Wire rope and its associated cable assemblies are an essential part of the marine industry in a variety of load-handling applications. In many instances, maintenance and replacement of these cables involves multiple layers of fabrication and service providers who rely on quality management processes to ensure the correct product is supplied to the end-user.

On January 4, 2021, a Fast Rescue Craft (FRC), while being manually winched to its stowed position onboard a floating offshore installation in the Gulf of Mexico, fell approximately 135 feet into the water when its wire rope end termination failed. Luckily, the crew of the FRC had exited the craft just moments before the incident. The subject wire rope in the casualty had failed within one month of its Continue reading “The importance of verifying wire rope terminations”

Corrosion found on twist-lock foundations

The American Club has published guidance and some lessons learned following an incident that involved corrosion of the twist-lock foundations and pad eyes.

A general cargo vessel had been modified to carry containers on the cargo hatches. Various twist-lock foundations and pad eyes had been welded to the hatch covers to secure containers. While the vessel was in port preparing to offload and load containers, the newly arrived Chief Officer noticed that many of the twist-lock foundations and pad eyes were significantly corroded. He raised his concern with the Master. They jointly inspected them and found them likely to be unsafe due to the excessive corrosion. Continue reading “Twist-lock foundations should be inspected regularly”
