Skilful Vessel Handling
Skilful Vessel Handling Capt. Øystein Johnsen MNI Buskerud and Vestfold University College March 2014 Manoeuvring of vessels that are held back by an external force This consideration is written in belated wisdom according to the accident of Bourbon Dolphin in April 2007 When manoeuvring a vessel that are held back by an external force and makes little or no speed through the water, the propulsion propellers run up to the maximum, and the highest sideways force might be required against wind, waves and current. The vessel is held back by 1 800 meters of chain and wire, weight of 300 tons. 35 knops wind from SW, waves about 6 meter and 3 knops current heading NE has taken her 840 meters to the east (stb), out of the required line of bearing for the anchor. Bourbon Dolphin running her last anchor. The picture is taken 37 minutes before capsizing. The slip streams tells us that all thrusters are in use and the rudders are set to port. (Photo: Sean Dickson) 2 Lack of form stability I Emil Aall Dahle It is Aall Dahle’s opinion that the whole fleet of AHT/AHTS’s is a misconstruction because the vessels are based on the concept of a supplyship (PSV). The wide open after deck makes the vessels very vulnerable when tilted. When an ordinary vessel are listing an increasingly amount of volume of air filled hull is forced down into the water and create buoyancy – an up righting (rectification) force which counteract the list. Aall Dahle has a doctorate in marine hydrodynamics, has been senior principle engineer in NMD and DNV. -

After 88 Years - Four-Masted Barque PEKING Back in Her Homeport Hamburg
Four-masted barque PEKING - shifting Wewelfsfleth to Hamburg - September 2020 After 88 Years - Four-masted Barque PEKING Back In Her Homeport Hamburg Four-masted barque PEKING - shifting Wewelfsfleth to Hamburg - September 2020 On February 25, 1911 - 109 years ago - the four-masted barque PEKING was launched for the Hamburg ship- ping company F. Laeisz at the Blohm & Voss shipyard in Hamburg. The 115-metres long, and 14.40 metres wide cargo sailing ship had no engine, and was robustly constructed for transporting saltpetre from the Chilean coast to European ports. The ship owner’s tradition of naming their ships with words beginning with the letter “P”, as well as these ships’ regular fast voyages, had sailors all over the world call the Laeisz sailing ships “Flying P-Liners”. The PEKING is part of this legendary sailing ship fleet, together with a few other survivors, such as her sister ship PASSAT, the POMMERN and PADUA, the last of the once huge fleet which still is in active service as the sail training ship KRUZENSHTERN. Before she was sold to England in 1932 as stationary training ship and renamed ARETHUSA, the PEKING passed Cape Horn 34 times, which is respected among seafarers because of its often stormy weather. In 1975 the four-master, renamed PEKING, was sold to the USA to become a museum ship near the Brooklyn Bridge in Manhattan. There the old ship quietly rusted away until 2016 due to the lack of maintenance. -Af ter returning to Germany in very poor condition in 2017 with the dock ship COMBI DOCK III, the PEKING was meticulously restored in the Peters Shipyard in Wewelsfleth to the condition she was in as a cargo sailing ship at the end of the 1920s. -

Why Consider Inverted Bows on Military Ships Or Why
ATMA 2018 WHY CONSIDER INVERTED BOWS ON MILITARY SHIPS? OR WHY NOT ? Philippe GOUBAULT Naval Group – Direction of Innovation and Technical Expertise – Bouguenais (France) Stéphane LE PALLEC, Yann FLOCH Naval Group – Surface Ship Design Department – Lorient (France) SOMMAIRE La forme des étraves des navires a connu de nombreuses évolutions au cours de l’histoire de la construction navale. Ces évolutions suivent en général l’avènement de nouveaux besoins ou de nouvelles connaissances. L’industrie navale est cependant très conservatrice, ce qui tend à ralentir des évolutions significatives. Ceci s’applique en particulier au cas des étraves discutées dans ce papier. Dans les dernières 50 -70 ans, ce qui est assez court dans l’échelle de l’histoire, les étraves des navires ont évolué pour intégrer un dévers assez important afin de mieux surmonter les vagues lors d’opérations sur mer forte. L’action de ces étraves tend à disperser les embruns sur les côtés et produire des forces de rappel afin d’éviter l’enfournement de l’avant sous la vague. Cela a marqué une amélioration par rapport aux étraves assez droites des navires avant cette période. On assiste cependant depuis le début des années 90 à une recrudescence des designs de navires avec des étraves droites ou inversées. Il est légitime de se demander ce que cela apporte et quel risque prend on le cas échéant en adoptant ce changement. Naval Group s’est lancé depuis une dizaine d’année dans un programme complet d’études et d’essais afin de déterminer l’intérêt et les conditions de succès d’un design avec une étrave inversée. -

Parts of a Ship: the Basics
Parts of a Ship: The Basics PORT SIDE MAIN FORE MAIN WINDLASS STERN AFT BOW TILLER MAST MAST HATCH HATCH STARBOARD SIDE Overhead view of the schooner Sultana he front of a ship is called the bow, and the back is called the stern. If you were standing T on the ship’s deck looking forward (towards the bow), the left side would be the port side and the right side would be the starboard side. Close to Sultana’s stern is the tiller, a long stick attached to a device called a rudder used for steering the ship. Other important items include the main mast, the fore mast and the windlass (a large simple machine used for pulling up the anchor). POOP DECK QUARTER DECK MIDDLE DECK FORE DECK MAIN TILLER HATCH ultana’s deck is divided into four sections. At the front of the ship is the fore deck, where S the anchors are stored and the fore mast is located. The largest section of the ship is the middle deck where the main hatch is located. Historically, this is where cargo would have been loaded and unloaded. Towards the ship’s stern is the quarter deck. On larger ships, only the high ranking officers were allowed to stand in this area. Sultana’s smallest deck is the poop deck, where sailors steered with the tiller.

The MAROB Voluntary Marine Observation Program
The MAROB Voluntary Marine Observation Program (With instructions specific for sending MAROBs via the QTH Reporter webform) All Information with Respect to the MAROB Program is Preliminary and Subject to Revision What is the MAROB Program? The MAROB Program is an experimental voluntary marine observation program of the National Weather Service in the early stages of development. It seeks the participation of all mariners, both commercial and recreational, which are not part of the more in-depth Voluntary Observing Ship (VOS) program. It is the goal of the program to collect as many marine observations as practicable, to improve the accuracy of coastal, offshore and high seas forecasts, by taking advantage of technological advancements in marine communications and the proliferation of the Internet. Who May Participate in the MAROB Program? Any mariner is welcome to participate in the MAROB program. However, we ask that commercial vessels, which are routinely underway, consider participating in the international Voluntary Observing Ship (VOS) program, see www.vos.noaa.gov or call 1-228-688-1457 for information. I Have Some Concern about Piracy or my Competition If you have some concern about piracy or your competition (e.g. while racing or fishing) you should likely not participate in a voluntary vessel position or weather reporting system such as MAROB where your position is widely disseminated and may become known to others. Where some degree anonymity is desired, use the identity "SHIP" in your report. Never enter a report with a false position What Training is Required to Participate in MAROB? At present, no training is required to participate in the MAROB Program. -
THE DELAWARE V. the OSPREY. [2 Wall
YesWeScan: The FEDERAL CASES Case No. 3,763. THE DELAWARE V. THE OSPREY. [2 Wall. Jr. 268;11 Am. Law Reg. 15; 1 Phila. 358, 401; 27 Hunt, Mer. Mag. 589; 9 Leg. Int. 82, 130; 4 Am. Law J. (N. S.) 533.] Circuit Court, E. D. Pennsylvania. Sept. Term, 1852. COLLISION AT NIGHT—STEAMER AND SAILING VESSEL—SIGNAL LIGHTS. 1. Although the court cannot establish a rule to bind vessels navigating the high seas to carry signal lights, yet where one vessel does so and another does not, the court, in case of a collision, will go some way to treat the dark boat as the wrong doer. [Cited in Baker v. The City of New York, Case No. 705; The Frank Moffatt, Id. 5,660. Explained in Pope v. The B. B. Forbes, Id. 11,275. Distinguished in The Hypodame, 6 Wall. (73 U. S.) 225.] 2. The court going in advance of hitherto adjudicated cases, would seem to enforce the obligation upon all boats navigating bays and rivers, not only to show lights on an approach, but to carry them constantly. [Cited in The City of Savannah, 41 Fed. 893.] The steamer Osprey was on her way to sea, out of Delaware bay, with three signal lanterns in place, heading for the lights of Cape Henlopen, on the west. The barque Delaware, without any lights, came into the capes with the wind free to pass up the bay, and the tide against her. When at some distance from the steamer, the sails of the barque shut out the Cape Henlopen lights from the pilot of the steamer, and from this fact the pilot inferred a sailing vessel was between him and them, and of course, that the sailing vessel was heading to starboard of the steamer.
