ABS Guide: Fatigue Assessment of Offshore Structures

ABS has released its updated Fatigue Assessment of Offshore Structures guide, which incorporates updated approaches for addressing fatigue including new S-N curves and guidance regarding fatigue strength based on fracture mechanics.

Fatigue assessment is a process where the fatigue demand on a structural element is established and compared to the predicted fatigue strength of that element. One way to categorize a fatigue assessment technique is to say that it is based on a direct calculation of fatigue damage or expected fatigue life. Three important methods of assessment are the Simplified Method, the Spectral Method and the Deterministic Method. Alternatively, an indirect fatigue assessment may be performed by the Simplified Method, based on limiting a predicted (probabilistically defined) stress range to be at or below Continue reading “ABS updates Fatigue Assessment of Offshore Structures guide”

The National Transportation Safety Board (NTSB) has published an investigation report on the explosion and subsequent sinking of barge Alaganik in the Canal Passage, off Alaska in July 2019, which resulted in one fatality. The investigation identified ignition of gasoline vapor from a fuel cargo tank as key cause of the accident.

On 7 July 7 2019 an explosion occurred on the barge Alaganik as it was moored port side to the end of the Delong Dock in Whittier, Alaska. The vessel was serving as a platform for pumping fish cargo ashore from fishing vessels and tenders that came alongside. It also provided diesel fuel and gasoline to the fishing vessels. No cargo operations were ongoing when the explosion occurred.

Despite the efforts of shore-based responders to fight the ensuing fire, the vessel eventually sank in 60–80 feet of water. The Continue reading “Ignition of gas vapor onboard barge Alaganik the cause of fatal explosion reveals NTSB Report”

RMI has published its Annual Report on the investigation of Marine Casualties, revealing that it received reports of 806 very serious marine casualties, marine incidents, and occurrences in 2019. Accidental falls, enclosed space incidents and collisions-groundings during pilotage were the main issues of concern last year.

Specifically, during 2019:
– 17 very serious casualties were reported to the Administrator. Two very serious casualties resulted in the constructive total loss of a ship, while 11 others resulted in the loss of one or more lives. Additionally, four occurred on yachts and resulted in their constructive total loss due to fire.
– Accidental falls were the leading cause of death during 2019, with seven lives lost. Four of these fatalities were the result of falls from height and three were falls overboard. Improper enclosed space entry also resulted in the loss of two seafarers
– There were 331 marine casualties.
– Serious injuries (resulting in incapacitation for 72 hours or more) were by far the most frequently occurring marine Continue reading “RMI publishes its annual report on marine casualties”

Autonomous Barge Master gangway landing solution set to improve safety for offshore structures

Autonomous Barge Master gangway
Autonomous Barge Master gangway

A new autonomous landing solution for offshore structures, called the Barge Master gangway, is designed to significantly improves both safety and performance.

Through a combination of radar technology, cameras and sensors, Bosch Rexroth’s system automatically attaches the landing from the ship to the required site without the need for manual input. This means that the operation is consistent and reliable, regardless of weather and ocean conditions.

After the automated landing procedure, the Barge Master gangway is held safely in place through a combination of motion compensation and the ship’s dynamic positioning.

“There are a number of benefits to the autonomous landing system,” says Rene Coppens, Business Development Manager for Continue reading “Autonomous Barge Master gangway landing solution set to improve safety for offshore structures”

What types of biofuels could ships burn in 2030?

What types of biofuels could ships burn in 2030?
What types of biofuels could ships burn in 2030?

Shipping is the backbone of the global economy, responsible for about 90% of world trade. But it also accounts for almost 3% (and rising) of man-made carbon dioxide emissions. The industry’s regulator set a series of emission-cutting targets back in 2018 aimed at driving a transition away from high-polluting fossil fuels. If the more ambitious goals are to be hit, the world’s ships will need to start burning new, clean fuel by 2030; such as biofuels. The question is, which one?

1. What are the bio-bunker options for ships after 2030?
Ships burn about 5 million barrels of fossil fuel every day, pumping a constant stream of CO2 and other chemical nasties into the atmosphere. Yet figuring out the fuel of the future isn’t just about emissions. It’s got to have enough power to propel gigantic tankers around the globe, be storable and transportable, and, of course, not too costly. Here’s a list of the front- Continue reading “What types of biofuels could ships burn in 2030?”

Artificial intelligence based system detects misdeclared cargo

AI based system detects misdeclared cargo

Dealing with misdeclared cargo and its consequences is one of the most challenging issues for the shipping industry at this current time. Known to be at the root of many major marine accidents, including fires causing loss of life and significant damage, shipping lines have been seeking to develop an approach to detect and reduce the risks of misdeclarations.

In July 2020, the National Cargo Bureau (NCB) reported that its recent inspection initiatives revealed an alarming number of containers included misdeclared dangerous cargoes. Citing the fact that on average a containership suffers a major fire every 60 days, the NCB reported that it conducted more than 32,000 dangerous dry and tank good inspections in the US in 2019, finding that more than six Continue reading “Artificial intelligence based system detects misdeclared cargo”

Following the standard tanker practices of sampling when loading petroleum products could save owners millions of dollars in claims and save loss of time and ensuing losses for charterers and shipowners says P&I Club, Gard. When it comes to dealing with liquid cargo contamination claims, the majority of the losses could have been avoided if the vessel had followed basic tanker seamanship practice. Gard has previously highlighted the importance of manifold samples as the multimillion dollar samples for tankers. This alert focuses on the importance of the manifold and first foot samples, and the lessons learnt from cases arising in the Black Sea ports. A recent notification from Gard’s correspondents, Novorissiysk Insurance Company Nostra Ltd., highlighted several cases of flash point depression in gasoil Continue reading “The importance of manifold and first foot samples at load ports”

Ever Smart: containers overboard

MAIB have published their report on the container ship Ever Smart. On 30 October 2017, the UK registered container ship Ever Smart suffered a container stow collapse while on passage between Taipei, Taiwan and Los Angeles, USA resulting in containers overboard. The master had changed the ship’s passage plan to avoid severe weather caused by a developing depression east of Japan. The ship continued in heavy seas; rolling and pitching heavily with frequent bow flare slamming. Once the weather had abated, the crew discovered that the container stacks on the aft most bay had collapsed and toppled to port. Of the 151 containers in the stow, 42 containers overboard and 34 were damaged. Superficial damage was caused to the ship.

Coatings for scrubbers

Corrosion has emerged as the arch-enemy of the exhaust gas cleaning systems as the uptake of the technology rose with the entrance into force of the IMO 2020 sulphur cap.

Like with any new technology, scrubber maintenance and operation has been a learning curve for ship owners and operators, especially in the context of preventing failures of the technology and reducing downtime.

“Corrosion mainly happens on the overboard pipes, the last piece from GRE piping and connection to shell plating of the hull, especially near the connections and welding seams, and the area on the external hull around the overboard pipe outlet,” said Manuel Hof, Sales & Production Executive, NACE Coating Inspector Level 2 at Subsea Industries.

“These areas will need to be protected against acid-containing water (highly corrosive sulphuric acid) coming from the exhaust gas cleaning system. Continue reading “Scrubbers Coatings as important as quality material of scrubber components to prevent corrosion”
