A pool of black oil shimmers on the tanker's rusty red deck. It's not fresh oil, but rather, a sheet of fossilized sludge that hints at the vessel's deteriorating condition and dire need of maintenance.

- Safety & Shipping Review 2021: 49 large ships lost worldwide last year. Total losses down 50% over 10 years. Number of shipping incidents (2,703) declines year-on-year. - Shipping industry resilient through pandemic, but crew change crisis has long-term consequences. Covid-19 delays and surge in demand for shipping increasing cost of claims. Inadequate ship maintenance could bring future claims. - Suez Canal incident shows ever-increasing vessel sizes continue to pose a disproportionately large risk with costly groundings and salvage operations. High number of fires and containers lost at sea. - South China, Indochina, Indonesia and Philippines maritime region is the global loss hotspot.

Biofouling is challenging for underwater sensors, especially for long-term in situ monitoring in marine environments. Biofouling on in situ sensor surfaces can shorten their operating lifetime, increase the cost and frequency of maintenance, and result in signal drift and data errors.

The introduction of a surface into the marine environment begins a process known as biofouling, which increases the weight and hydrodynamic drag of the fouled structure. This process is detrimental to maritime vessels and costs the industry ∼$150B in fuel and maintenance spending annually. Preventing the settlement of fouling organisms mitigates these issues and limits the spread of non-indigenous species (NIS). This is primarily achieved via antifouling paints. Ultraviolet light is a sterilization method used in water purification, food storage packaging, and within medical fields. Ultraviolet C (UV-C) radiation interacts with DNA to prevent growth, proliferation, and survival of bacteria, and biofilm formation. Recent progress in microelectronics technology has advanced the range of commercially available light-emitting diodes (LEDs) to include the UV wavelengths, and the reduced size and cost has allowed their integration into previously inaccessible locales. This study builds on recent progress in integrating UV-C LEDs into UV-lucent silicone tiles for fouling control. The operational cycle needed to prevent growth of Navicula incerta cells was determined. Constant irradiance at a peak of 5.77 μW/cm2 resulted in a significant reduction in diatoms within 2 h, and a 2 log and 3 log reduction after 48 h and 5 days, respectively. Duty cycling (pulsing) in all variations from 50 to 2.5%, indicated significant reductions in cell densities, and the lowest cycle could effectively reduce biofouling growth and increase the longevity of the LEDs for up to 45.6 years. Irradiance and exposure were altered over a set duration and indicated a restriction in growth between 0.01-0.82 J/cm2 and an increased mortality at irradiances > 2.65 J/cm2, suggesting an effective antifouling threshold between these dosages. The effective dosage for 1 log reduction in fouling was estimated to be 25 J/cm2 but varied according to irradiance delivery method. Effective dosage for a 1 log re

Up to a thousand ships flagged to the Cook Islands, Palau, Sierra Leone, and Togo will be targeted for safety, maintenance and seafarer welfare inspections across the Mediterranean Sea in the coming eight weeks by an army of inspectors from the International Transport Workers' Federation (ITF), seafarers' unions and port authorities.

- A UK-first collaboration is set to use satellites to monitor coastal changes in a bid to create safer shipping navigation channels. - The project will see Peel Ports, the UK's second largest port operator, partner with the National Oceanography Centre (NOC) and Channel Coastal Observatory (CCO) to employ satellite surveillance and assess where maintenance is needed over a six-month period. - Funded by UK Space Agency Small Business Research (SBRI), we will use our patented coastal mapping technology to support Peel Ports in building targeted dredging operations across the Mersey and Medway estuaries. - Offering greater insight into changes to the marine environments around two of the UK's most important waterways, Peel Ports will use the data to ensure safer access to the Port of Liverpool and Port of Medway for arriving ships.

Maritime security is an essential component of national security, and the effective maintenance of China's maritime security urgently needs a complete guarantee of the rule of law. Since the founding of the People's Republic of China in 1949, the construction of domestic law on maritime security has undergone three phases: slow development, formation and refinement. Although the rule of law in the seas has been constantly improved, it has provided essential safeguards for maintaining China's maritime sovereignty, security, and rights and interests. It has facilitated the development of maritime undertakings. However, it still faces problems such as the lack of an explicit constitutional basis, the law of the sea is not an independent departmental law, the absence of the fundamental law of the sea, the lack of operability of marine legislation, and the existence of some gaps in marine laws. Given the problems with the current domestic law on maritime security, it is necessary to make improvements in the following areas: adding marine provisions to the Constitution, formulating the fundamental law of the sea and other marine laws, improving local marine laws, and introducing implementing regulations.
