The Ship Structure Committee is pleased to announce the publication of a new report, SSC-474, titled Structural Assessment of Aged Ships, authored by Mr. Gregory Walker, Mr. Brendan Connell and Mr. Sean Kery of CSRA. The detailed 75 page report is available for free using the link at the end of the article below.
The report describes the development of an assessment process to accurately predict the survivability of a corrosion-degraded ship in specific wave conditions. The method developed utilizes a ship specific 3-D hydrodynamic model to simulate the ship’s rigid body dynamic response to wave conditions, measuring the resulting ship motions and pressure distribution on the hull. Pressure and acceleration data from the hydrodynamic model is then input into a Continue reading “New method to assess structure durability of aged ships announced by Ship Structure Committee”
The Swedish P&I Club has described a case of an oil spill during a vessel’s bunkering operations which led to an oil spill, the cause of which was a broken valve. Following investigation, the Club recommended that all involved parties should be informed when tanks are switched and that the crew must always ensure the valves are completely shut and working.
The vessel was loading in port and had also planned to bunker fuel using shore trucks. The plan was to load the fuel into port tank 2 and fill it 96%, but the chief engineer changed this just before loading and instead wanted to load port and starboard 3 tanks. The plan was to fill these tanks 90%. The number 3 tanks were half the size of the port and starboard 2 tanks.
The UK’s polar research ship RRS Sir David Attenborough was launched into the River Mersey, Birkenhead on Saturday July 14.
Once in the river, tugs towed the 129-meter (423-foot) 10,000 ton hull to Cammell Laird’s wet basin for the next stages of construction. The polar research ship is scheduled to commence operation in 2019.
More than 3,000 shipyard workers, engineers, scientists and maritime industry experts gathered with special guest speakers, including world-renowned broadcaster Sir David Attenborough, to celebrate.
At a time of political and economic uncertainty, the 21st annual Seawork exhibition was a clear demonstration that the UK and European commercial marine sector is open for business. With deals being struck, exhibitors showing confidence and visitor numbers up, Seawork was again successful at bringing together businesses, trading opportunities and new ideas.
The commercial marine sector is a vital facilitator to trade, security and maintenance of the world’s coastlines.
The UK Maritime Minister, Nusrat Ghani, opened the 21st edition of Seawork International on Tuesday 3 July with her speech focusing on the importance of the maritime sector, seafarer training, women in maritime, and Maritime 2050; the long-term strategy for the future of the UK maritime industries. As the engine of British trade, the maritime sector supports nearly Continue reading “Seawork 2018 speeds to success”
In a recent study the Swedish Club has warned that vessels propelled by medium or high speed diesel engines have a claims frequency two and a half times higher than slow speed engines with an average claims cost of about $650,000.
Statistically, a vessel will suffer between one and two incidences of main engine damage during its life time, according to the club. However, the incidence rate varies by vessel class (and engine type).
“Our research shows that bulkers and tankers are the best performers for claims cost,” said senior technical advisor Peter Stalberg. “Most of these vessels have slow speed engines. Conversely passenger vessels/ferries have the highest frequency of main engine claims – 0.066 claims per vessel and year. Often these vessels have multiple medium speed engine installations.”
