 What happens when there is a strong onshore wind and you have to berth a ship without the assistance of tugs to a pier or jetty that is not strong enough to bear the impact or is not sufficiently ‘fendered’? In such a situations, the master or the pilot takes the recourse of using the ship’s anchor as well as the wires available on board in a specific way to minimize the impact of the fall. This is done by mooring ship in such a way where a vessel is berthed alongside the quay by employing a stern mooring shackled to the offshore anchor cable in the region of the ‘ganger length’. When approaching the berth, the offshore anchor is deployed and the weight on the cable and the stern mooring act in unison to hold the vessel just off the quay. Baltic mooring is a combination mooring of a vessel alongside the berth which employs a stern mooring shackled to the offshore anchor cable in the region of the “ganger length”. When approaching the berth, the offshore anchor is deployed and the weig

  A buoy is a type of object that floats in water and is used in the middle of the seas as a locator or as a warning point for ships. Buoys are generally bright (fluorescent) in colour and made of PVC tubing. Some buoys have a sturdy one-piece polyethylene shell and hard skin shells which act as  Ultraviolet light absorbers with a sandblasted finish. Mooring buoys are a type of buoy to which ships can be moored in deep oceanic areas. A mooring buoy weighs more than standard buoys. The mooring buoy is designed in a manner that there is a heavier weight located right at the bottom of the sea. This weight is like an anchor holding the buoy afloat in the water. A mooring buoy has loops or chains attached to its top that float on the water. These chains are provided so that ships or boats can be effectively moored to them. It is essential to use the mooring equipment correctly. While approaching the Buoy, the yellow pick-up line should be close. It can be retrieved using the boat hook

We have been intrigued by this question: How are ships ‘parked’ upon their arrival in ports, jetties, and piers? Unlike cars, they can’t simply be put off gear and parking brakes! Ships don’t have brakes in the first place. Ships need to be fastened and fixated soundly for conducting all kinds of shore operations such as cargo loading/unloading, refuelling, bunkering, ballasting/deballasting, boarding/deboarding, maintenance, repairing, and often for idle times based on voyage schedules and berth or workforce availability. So, mooring or the system of securing a vessel soundly for the purposes mentioned above is indispensable in studying ships and offshore structures.  Differences between mooring, docking and anchoring It is common to get confused with the terms mooring, docking and anchoring and may use them interchangeably. But there are stark differences between them.  Anchoring is the system of securing a vessel amid the sea when the ship is not near the vicinity of a per

If you have high blood pressure, you may wonder if medication is necessary to bring the numbers down. But lifestyle plays a vital role in treating high blood pressure. Controlling blood pressure with a healthy lifestyle might prevent, delay or reduce the need for medication. Here are 10 lifestyle changes that can lower blood pressure and keep it down 1. LOSE EXTRA POUNDS AND WATCH YOUR WAISTLINE Blood pressure often increases as weight increases. Being overweight also can cause disrupted breathing while you sleep (sleep apnea), which further raises blood pressure. Weight loss is one of the most effective lifestyle changes for controlling blood pressure. If you're overweight or have obesity, losing even a small amount of weight loss can help reduce blood pressure. In general, blood pressure might go down by about 1 millimeter of mercury (mm Hg) with each kilogram (about 2.2 pounds) of weight lost. Also, the size of the waistline is important. Carrying too much weight around th

  Carbon Capture Carbon capture is defined as capturing carbon dioxide at the point of emission or from the atmosphere, either indirectly or directly. At this point, carbon is separated from other gasses, transported, and then later buried or stored in a suitable deep, underground place. In 2010, worldwide carbon dioxide emissions from fossil fuels were around 32 Gigatons. Industrial operations and stationary emission sources such as cement manufacturing, power plants, and refineries are responsible for producing carbon dioxide in the atmosphere. Between 1750 and 2010, approximately 50% of the overall anthropogenic carbon dioxide emissions have been generated in the previous 40 years. Types Of Carbon Capture Pre-combustion carbon capture Pre-combustion carbon procedures involve trapping carbon before the combustion process of fossil fuels ends. Synthesis syngas or gas is produced when oil, coal, or natural gas is heated in oxygen and steam. The gas is composed of carbon dioxide, carbon
