SIGTTO presents recommendations for management of cargo alarm systems

The Society of International Gas Tanker & Terminal Operators Ltd (SIGTTO) published the first output from the Human Element Committee, ‘Recommendations for Management of Cargo Alarm Systems’, recommending the implementation of alarm management philosophies for cargo alarm systems on gas carriers.

The purpose of these recommendations is to encourage owners to create an alarm management system that will address the design, management and operation of alarm systems. Owners may find valuable assistance from Classification Societies, alarm system designers and shipyards.

This document provides guidance for all types of gas carriers, from large LNG carriers to the smallest LPG carriers. All gas carriers will need to have alarm management processes, but less complex alarm systems will be easier to set up.

“A fire in the engine room is any seafarer’s worst nightmare,” says Tom Backlund, Wärtsilä’s General Manager Large Bore Engines.

This is especially true when it comes to fuel leakages in vessel engine rooms. This is why the International Convention for the Safety of Life at Sea (SOLAS) regulation, enforced by the International Maritime Organisation (IMO), stipulates a number of minimum safety standards for operations throughout the vessel, including the engine room, with a strict limit for splash guards’ surface temperatures that could ignite liquid and cause fires.

Wärtsilä continuously delivers improvements to its engines and has introduced a variety of new solutions to comply with the hot surface Continue reading “Smart fuel hose set to enhance safety at sea”

Hapag-Lloyd tests ship-painting robots

Posted on by News Hound

Traditional manual work is increasingly being replaced by automated processes, such as self-driving Automated Guided Vehicles in container terminals. Thanks to robots, the quality of ship painting can also be improved and the docking time shortened. Hapag-Lloyd is currently testing the process with nine ships.

Keeping barnacles, mussels and algae off the hull – the subject of fouling is as old as shipping itself. Fouling dramatically increases drag, which results in high fuel consumption and makes it harder to achieve climate targets. So, it’s a question that repeatedly arises: How can fouling be efficiently and reliably prevented over a period of five years, when a vessel will have to go into a shipyard anyways for its regular Continue reading “Hapag-Lloyd tests ship-painting robots”

The boat wings started as an unfinished idea in Eirik Bøckmann’s head. Now they’re being mounted on a ferry in the Faroe Islands.

Actually, he doesn’t call them boat wings, but wavefoils. Eirik Bøckmann won the regional finals of the NTNU Researchers’ Grand Prix with a lecture on wave-propelled ships in 2013.

The wavefoils on the front of the ship enable the waves to contribute to propelling the ship forward. This reduces fuel consumption. At the same time, the foils can dampen some of the pitching and heaving motion from the waves and provide a more comfortable journey.

The technology group Wärtsilä’s hybrid power module solution, the Wärtsilä HY, is now fully operational on the ‘Vilja’, an escort tug owned by the Swedish port of Luleå. The tug was built at Gondan Shipbuilders in Asturias, Spain and was delivered in the end of June 2019 following successful completion of the commissioning and sea trials. The Wärtsilä HY is the first hybrid power module in the marine industry, and its operational application onboard the ‘Vilja’ marks a new era in shipping.

The solution has been specially developed to meet the specific needs of the tug market. It features operating characteristics that include ‘green mode’, with zero emissions and no noise, a ‘power boost’ that delivers a higher bollard pull than any other conventional solution of Continue reading “Delivery of first vessel with Wärtsilä HY hybrid technology marks new era in shipping”

Ammonia comes under the spotlight as a potential new low emissions fuel

Posted on by News Hound

Ammonia can be safely and effectively applied as a marine fuel to reduce harmful emissions according to new research published by C-Job Naval Architects.

The ground-breaking research uses a new concept design, an ammonia carrier fuelled by its own cargo, to study the concept of using ammonia as a marine fuel and achieve a significant reduction in greenhouse gas emissions in shipping. It shows ammonia can be used as marine fuel if a number of safety measures are included in the design.

Niels de Vries, Lead Naval Architect at C-Job Naval Architects and research lead, said: “Reviewing all ammonia power generation options, Continue reading “Ammonia comes under the spotlight as a potential new low emissions fuel”

DNV GL has published updated bulk cargo liquefaction guidance information

Posted on by News Hound

DNV GL Classification society has updated its bulk cargo liquefaction guidelines. Originally published in 2015, the revised guidelines are based on feedback from readers and practical experiences that have arisen historically. The guidelines focus on design and operation of vessels with bulk cargoes that may liquefy.

Specifically, the revised guidelines provide additional material to better describe precautions to be followed during voyages or even the steps to be taken in the possibility of cargo liquefaction.

Swedish Club publishes booklet on preventing wet damage to cargo on bulk carriers

Posted on by News Hound

The Swedish Club has highlighted how to avoid wet damaged cargo on bulk carriers in a 32 page pdf booklet, which can be downloaded below. The Club says that heavy weather in combination with leaking hatch covers is the most common cause of wet damage on cargo. However, the main concern is the incorrectly applied and poorly maintained cargo hatch covers and sealing systems.

As a result of information collected from its claims handling, many cargoes of steel and steel coils, grain, peas and solidified cement were damaged by sea and rainwater enabling the report to be produced. In fact, 34% of all insured bulk carriers suffered a cargo claim in 2017 and this has increased by 75% since 2014. For 2017, the average cargo claim on a bulk carrier was almost USD 70,000.

Report finds fire onboard cargo vessel was due to lack of compliance with SMS

Posted on by News Hound

The NTSB has published its report on the fire that took place on board the cargo ship Chipolbrok Moon on 23 May 2018. The fire occurred while the ship was moored at the Industrial Terminal West in Greens Bayou in the Port of Houston, Texas.

The incident
On May 21, the Chipolbrok Moon arrived at Industrial Terminal West in Houston. After the ocean voyage and before offloading the cargo, the steel sea fastener tabs used to secure the turbine components had to be removed by cutting, using an oxygen/acetylene torch.

The next afternoon, a marine chemist tested the atmosphere in cargo holds no. 2 port, no. 3 port and starboard, and no. 4 starboard for oxygen content and presence of flammable vapors to determine if it was safe to carry out hotwork.
