Boarding one vessel from another can be particularly hazardous. Try to avoid it if at all possible. Never attempt this if a vessel is moving. Where it is necessary, it is normally the responsibility of the ship lying outboard (i.e. furthest from the dockside) to provide safe access to the other vessel. The only exception is where the outboard vessel has a much lower freeboard (i.e. the deck is much lower, so access would involve climbing), in which case the vessel with the higher freeboard is responsible for giving you safe access. This will usually involve using rope ladders and is the only time you should use them for gaining access. Don’t try to climb a rope ladder unless you have been shown how to do so safely. [links]

Ship’s equipment: Never attempt to examine any equipment on board until you have consulted a responsible officer. Unskilled interference with safety equipment, navigational apparatus or electrical systems can affect the seaworthiness of the vessel, jeopardising the safety of the passengers and crew. You would be committing a criminal offence.

Using these animals, the researchers were able to confirm that cancer cells often migrate via the lymph vessels first into nearby lymph nodes and from there continue to metastasize into vital organs. The surgical removal of the primary tumor enabled the researchers to simulate a disease situation that corresponded to that of a cancer patient after surgery: Daughter tumors and not the primary tumor became crucial for survival.

What role do the lymphatic vessels play in the metastasis of cancer cells? Scientists from the German Cancer Research Center and the Mannheim Medical Faculty of the University of Heidelberg developed a method to investigate this question in mice. The aim of the work was to identify new ways to block the dangerous colonization and spread of tumor cells. The researchers discovered that an antibody against a signaling molecule of the vascular system causes the lymphatic vessels in the tumor to die, suppresses metastasis and thus prolongs the survival of the mice. Based on these findings, approaches may be developed to prevent the dangerous spread of tumor cells. The results have now been published in the journal Cancer Discovery.

In their search for ways to prevent the development of metastases, the research team focused on the cells that line the lymph vessels from the inside, the so-called lymph endothelial cells. Endothelial cells control many important properties of the blood and lymph vessels and produce numerous signaling molecules and growth factors. The researchers found that the messenger substance angiopoietin 2 ensures the survival of lymph endothelial cells in tumors. An antibody that blocks angiopoietin-2 caused the lymph vessels in the tumor to selectively die. This interrupted the transport pathways for cancer cells to detach and prevented them from spreading to nearby lymph nodes. As a result, fewer daughter tumors formed in distant organs and the mice survived significantly longer. [links]

Just like healthy tissue, tumors are supplied by two vascular systems. In addition to blood vessels that supply oxygen and nutrients, the lymph vessels are responsible for transporting cells of the immune system and tissue fluid. The ability of cancer cells to spread through both pathways in the body and form daughter tumors, so-called metastases, has been known for a long time. In this work, the importance of the route via lymphatic vessels and the biological mechanisms involved were investigated for the first time in mice. more

Until now, it has been difficult to study the complicated architecture of a tumor and its spread in a living organism. The Heidelberg and Mannheim research team led by Hellmut Augustin has now succeeded in developing a suitable model system, as Nicolas Gengenbacher, first author of the current publication, reports: "The key to this was a direct transplantation of tumor tissue from one mouse to another without prior cell culture. In this model, the natural tissue structure was preserved and the cancerous tumors were able to form functional lymph vessels that were connected to the lymphatic system—a prerequisite for lymphogenic metastasis." here

Biofouling presents a major threat to the industry’s progress toward decarbonization targets. Biofouling is the accumulation of microorganisms, plants, algae, or small animals on wet surfaces that have a mechanical function, causing structural or other functional deficiencies. Maritime shipping and logistics companies face challenges in vessel marine performance related to macrofouling — the attachment of larger organisms such as barnacles, soft corals, and seaweed.

There are a number of boat hull cleaning practices to remove marine organisms off the hull of the boat while the boat is still in the water. “Conventional hull cleaning is conducted by divers using rotating-brush carts, or using ROVs equipped with rotating brushes or waterjets,” explained one expert. “Alternatively, preventive maintenance approaches have also been suggested, such as hull grooming on US Navy vessels, consisting of frequent and gentle wiping of the hull and continuous prevention methods, such as aeration or ultrasound transducers.”

[teresabelek]

Ancillary technology like Sofar Ocean’s Wayfinder platform provides data that can help schedule antifouling maintenance to improve vessel efficiency before macrofouling becomes a big problem. By combining the most accurate weather data from the Sofar network with custom vessel performance curves, Wayfinder is able to predict when a vessel might be underperforming due to fouling of the prop or hull. Marine logistics companies can use this information to schedule the appropriate cleaning — optimizing operational efficiency, improving vessel maintenance, and limiting unnecessary delays caused by biofouling.

Do not operate, or cause the vessel to be operated, if it is an unsafe vessel.

You may be asked to demonstrate that you have thought about the risks and hazards in your operation and taken steps to eliminate or minimise these. Your SMS will be useful in demonstrating that you are complying with your general safety duties.

The design allows for wider load variations as the monohull section supports a significant percentage of the vessel’s overall displacement, and by virtue of its steep deadrise, buoyancy rises exponentially. This supports increases in displacement, thereby preventing excessive hull sinkage, which on a pure catamaran hull design results in a significantly reduced bridge deck clearance when heavily loaded. here

Thunder Child II is fitted with quad Caterpillar C8.7 650hp (480 kW) engines coupled to France Helices SD3L surface drives in a staggered arrangement. This setup provides the desirable redundancy for her planned upcoming trans-Atlantic record attempt, as should one engine fail she will still be able to maintain planning speed. [links]

A basic galley is also provided aft in the spacious main cabin fitted with sink, 240V hob, microwave and fridge. Her lower forward cabin offers a comfortable living area with full sleeping and live-aboard facilities for her crew featuring five berths in four cabins, including a master’s cabin. [links]
