Shipyard Trivia: Locomotive Cranes – Steel Wheeled Beasts of Burden By Marcus W. Robbins, NNSY Historian & Archivist Shipyards have used various methods to move materials since their beginning. The very nature of the materials utilized within the trades are heavy, awkward and most times difficult to place. Manual labor could only go so far. Animal labor such as beasts of burden (oxen and horses) could only do so much also because Norfolk Navy Yard continued to service larger ships over time, which required the use of dry docks. Due to that change, both man and beast’s abilities to perform larger and heavier tasks decreased so cranes became the way of the future. For the full story, visit:https://ow.ly/G33550RBAN3

Check out this remarkable review of #bombinghitlershometownbook from the good people at The Cipher Brief! The reviewer writes, "I suggest you cinch your harness tight and know where your parachute is—you are sure to need it!" He's not wrong. https://lnkd.in/g-Mt-2Am

Gardener: Find heavy artillery for a thorough approach! For your work, you need decent transport. Heavy artillery that can withstand a knock and does not shy away from a thorough approach. And to transport all that soil and stones, sufficient loading capacity is also very nice. We understand that at bestelbus.nl. That is why we have a wide choice of sturdy pick-ups, tippers and vans with open bodies and sides for you. Ideal if you often drive around with trailers and mini excavators. Because all that fuss is fun, but your van must above all be able to pull a heavy cart. At Kleyn Vans we understand what you are looking for.

Having a longitudinal view is important - in the early days of NSPS (before it became NSS) two programs collided within the newly formed Non-combat Work Package. They both had the same overly optimistic schedule objective but one had to give way to the other. There was a long and drawn out analysis process, as governments are apt to do, about whether the JSS or Polar Icebreaker should go first in the build sequence. At the time the number of changes to the baseline design of JSS were down-played as a factor and the proven design was pitched as presenting the low risk option that would not add complexity to the JSS program. Now these changes are recognized and celebrated (and correctly so I submit) but both programs were targeting a 2017 delivery (was never realistic I know) and will now not deliver to 2025 and 2030 at the earliest. Today, the pendulum has swung further with the focus of discourse being on buying proven ships from a hot production run with zero changes and navies the world over being criticized for introducing too much change, resulting in rampant scope creep leading to blown budgets and schedules. If we accept that no two operators have identical requirements (based upon the mission mix and areas of operation), and that navies the world over will never accept zero change, then there has to be an alternative method! Perhaps that is to start from a blank sheet with a proven designer like Vard Marine Inc, undertake a concept development cycle with the Navy and shipbuilder engaged early and then lock in requirements without any (or very limited) opportunity for change thereafter - the client gets an optimal outcome tuned to their requirements, level of ambition and budget. We do this all the time with both military/government and commercial fleet owners around the globe ... why can it not be achieved on federal shipbuilding programs in Canada? Without a domestic ship design and engineering capability in Canada we cannot argue #NSS has created a truly sovereign shipbuilding capability. We also cannot, seemingly, get the results we desire!

Damen Marine Components - Rotary Vane Steering System The Rotary Vane steering system is ideal for all sea-going vessels as well as superyachts and naval vessels. The high-end design consists of an integrated tiller and cylinder which generates the same high torque at all possible steering angles. It is safe to operate as it has only one rotating part. It also requires relatively low maintenance. This system is available for steering angles up to 65 degrees. The wide torque range of the rotary vane gives greater flexibility in choosing the rudder system. The integrated tiller and cylinder are part of the actuator, which is designed to take the full vertical load of the rudder and rudder stock. This makes a separate rudder carrier rudder redundant. APPLICATION For all vessels with a torque range from 45 up to 1600 kNm #DMC #DAMENMARINECOMPONENTS #VESSEL #ROTARYVANE #STEERINGGEARSYSTEM #ASIANMARITIME #SINGAPOREMARITIM #MALAYSIA #INDONESIA #PRODUCTIVITY

Davits are the lifeline of the sea—without their robust operation, ships cannot set sail, as they ensure the rapid launch and recovery of lifeboats and rescue boats, protecting both safety and operational readiness. Featuring the PIV 3.6 E All Electric Davit – an innovative piece of equipment from Fairbanks Morse Defense and Welin Lambie. This advanced davit has been meticulously designed to meet the rigorous demands of combatant ship design, ensuring that it can withstand the challenges faced in various maritime operations. Crafted from lightweight aluminum, it not only enhances maneuverability, but also complies with essential shock and electromagnetic interference (EMI) requirements. The PIV 3.6 E is equipped with variable speed power hoist and lowering capabilities, allowing precise control during operations. To further enhance its functionality, the davit includes integrated boat chocks, which secure the rescue boat during transit, as well as a rigid-hulled inflatable boat (RHIB) docking frame, facilitating seamless and efficient operations in demanding environments. This is just one of the many industry-changing products made by Fairbanks Morse Defense.

Welcome back to '#Maritime Glossary'! Today, let's talk about the '#Knotting End.' 🚢🤔 In nautical terms, 'Knotting End' refers to the #tail end of a rope where a knot is tied. Sailors and #mariners often use various knots for different purposes, from securing lines to creating #loops or bends. Understanding how to tie a proper knot is crucial for seamanship, ensuring safety and reliability at sea.🧵🛠️ #ErasmusPlus #Shipbuilding #shipwright #AHOD360 #VocationalEducation
