LISCR has published a notice to ensure people are checking pilot and embarkation ladders are genuine

The Liberia Maritime Authority (LISCR) has published a notice to provide guidance to vessel owners, operators and managers on compliance and maintenance of pilot and embarkation ladders, including notification on counterfeit products and the latest developments from IMO.

The Flag Administration says that several advisories have been issued recently concerning counterfeit pilot and embarkation ladders. In one case, a company copied a certified product and created their own counterfeit certificate for their pilot ladder and then sold the counterfeit product to customers who thought they were purchasing the genuine item.

New sensors could make stress monitoring cheaper

Soffshore wind turbines with a sunset backgroundhips, bridges and wind turbines can all be made safe using sensors that are just a few millimeters across. Researchers have borrowed the principle behind the technology from a vibrating guitar string.

Research scientist Guido Sordo compares the technology with a guitar string. But whereas the string has to vibrate at a given frequency to give precisely the right tone, oscillations in the sensor will vary depending on the behavior of the structure to which it is attached. These variations can provide warnings that something is wrong.

In this way it is possible for the sensor to identify Continue reading “New sensors could make stress monitoring cheaper”

New International Code of Safety for Ships Carrying Industrial Personnel

The IMO has adopted a new mandatory International Code of Safety for Ships Carrying Industrial Personnel (IP Code), anchored in a new SOLAS Chapter XV. The code enters into force on 1 July 2024 and enables cargo ships and high-speed cargo craft to transport and accommodate industrial personnel working offshore. A growing offshore energy sector, including renewable energy construction projects, has triggered the need for clear requirements to facilitate the safe and efficient transfer of technicians serving offshore installations.

Improperly maintained fluids in well control equipment systems

The Bureau of Safety and Environmental Enforcement (BSEE) has informed the industry about several recent offshore incidences where fluids used in well control equipment systems have been improperly maintained.

According to BSEE, two identified fluid contamination issues include the following:
– Nickel leaching into demineralized water in well control equipment, fluid systems.
– Calcium soap build-up in some control fluid systems, potentially caused by mixing the liquid concentrate with a chemical Continue reading “Improperly maintained fluids in well control equipment systems”

MCA approves the safe carriage of a greater number of workers in the offshore wind farm sector

Offshore boat on the waterNew rules proposed by the Maritime and Coastguard Agency to support the UK workers in the offshore wind farm sector are coming into force. The change will mean that vessels transporting those who work on offshore wind farms will be able to carry greater numbers of workers while still meeting safety standards.

The legislative changes followed discussions between the Maritime and Coastguard Agency and the industry looking at how to solve the logistical problems of transporting workers. Vessels that transport workers to offshore wind farms are currently not legally allowed to carry more than 12 people, no matter the size of vessel. Continue reading “MCA approves the safe carriage of a greater number of workers in the offshore wind farm sector”

ABS published life extension for ageing offshore assets guidance

Classification society, the American Bureau of Shipping (ABS), has refined its approach to ageing offshore assets with the publication of new guidance entitled ‘Life Extension of Floating Production Installations’.

The offshore assets guidance supports operators looking to extend the operational life of a floating production installation (FPI) by outlining clear Class requirements with a focus on safety. It is informed by lessons learned from ABS supported life extension projects and the findings of a series of FPI life extension joint development projects.

ABS publishes guidance on reduced manning requirements for safe operations

Guidance on the technology, systems and regulations needed for minimizing human presence on offshore facilities has been published by ABS. The whitepaper evaluates technology, regulations, systems and design issues. Reduced Manning on Offshore Facilities introduces some of the considerations essential for remotely operating floating facilities from a control center located nearby or onshore. To enable reduced manning without compromising safety, real-time monitoring, control automation and maintenance procedures incorporating remote diagnostics and simulations with minimal human intervention will be required.

“By utilizing new technologies, the number of personnel on board offshore assets can be reduced, minimizing personnel exposure and potentially reducing overall capital and operating costs. Since a significant reduction in manning is a fundamental shift for the industry, it Continue reading “ABS guidance on reduced manning requirements”

Research project to develop automated verification of wind turbine blade defects

DNV has launched a new collaborative research project to develop an automated data processing procedure for verification of detected wind turbine blade defects, with the aim of building trust and generating broader acceptance of automated data processing techniques across the industry and to inform future regulation.

The research project, which is being conducted in partnership with the University of Bristol and Perceptual Robotics, will investigate the automated verification, validation and processing of inspection data, collected by autonomous drones, to improve inspection quality and performance. The project aims to contribute to the development of the UK automated inspection industry.

NTSB issued an accident report has been issues by the National Transportation Safety Board (NTSB) on the overturning of lift-boat Kristin Faye while working alongside a platform in the Gulf of Mexico, in September 2019. The report identified the company’s inadequate preload procedure as key cause of the incident.

On 8 September 2019, about 1015 local time, the lift-boat Kristin Faye overturned while preparing to conduct work alongside a platform in the Gulf of Mexico, in Main Pass Block 64, about 18 miles east of Venice, Louisiana. All three crew members abandoned the vessel and were rescued. One person suffered minor injuries during the evacuation.

Consequently, an estimated 120 gallons of diesel fuel spilled into the water. The vessel was declared a constructive total loss at an estimated $750,000.

ABS updates Fatigue Assessment of Offshore Structures guide

ABS Guide: Fatigue Assessment of Offshore Structures
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”
