As we progressed towards innovation in the late 1960s, the size of oil tankers rapidly increased due to high demands, thus increasing also the incidents of explosions on tanks. The explosions were due to the ignition of flammable vapors in the tank’s atmosphere. The ignition source in many cases was the static electricity charge that…
Engine room watchkeeping is a continuous way for the watch to monitor and attend to the engine room and be able to rectify and troubleshoot problems that may occur anytime. Unfortunately, this is only applicable to conventional ships in which UMS or Unattended or Unmanned Machinery Space system is not yet installed. UMS is an…
Just like most of the equipment, tanks also have some limited pressure range to be followed for it not to be devastated. Excessive tank pressure and vacuum can surely cause serious problems or damage to the vessel’s structures. Generally, most of the tanks are normally designed to operate within the 200-1200 mmAq pressure range. Any…
A critical component to avoiding environmental or economic damage during a marine catastrophe is the ability to respond swiftly and appropriately in the aftermath of an accident to save all or a section of marine property that is in peril. Marine salvage is the saving of a ship, its cargo, or any other marine property…
Have you ever seen a boat at a boat show or even in a marina where there are no outboard motors or propellers mounted when you look at the back of the boat? Consequently, how do these boats move without any of these? These boats employ water-jet propulsion systems and are situated at the stern…
Can you identify the difference between and compare carbon fiber vs fiberglass? Contrary to what many people think, they are not the same thing. Both carbon fiber and fiberglass are composite reinforcing materials. Although both carbon fiber and fiberglass are composite materials, the fundamental distinction between the two is that while carbon fiber is created…
The question of how submarines work might be like magic for the general public, no one can even imagine how a submarine that is so massive can perform the miracle of submerging and then rising to the surface again. So, what is a submarine? A submarine, or “sub,” is a special kind of vessel that…
The vast world’s oceans hold unprecedented mysteries, among them being deep trenches. Ocean beds have valleys, plateaus, flatlands, and mountains, similar to the earth’s surface. Such features have led to the deepness of the world’s oceans, most of which haven’t been explored. The trenches are created when shifting tectonic plates slip below other plates. These…
Oil rig worker pay by role from the latest BLS data, from roustabouts to drillers and petroleum engineers, plus offshore rotations, training and safety.
Ships traveling through water create resistance to their forward motion. This resistance is called drag and is caused by the water molecules clinging to the ship’s hull and slowing it down. Frictional drag increases when the hull is fouled by marine growth. Historically, it was believed that painting ships below the waterline with copper coating…
