This announcement came via the folks at the Maritime Executive. For some of you, this may have been an anxious wait. I would expect to see a stream of new lubricants catering to tier 4 engines or specifically tailored for … Continued
In its most basic form the DP system is a control system that measures environmental inputs then sends commands to the thrusters to counter these forces to keep the vessel stationary, or to move it along a specified track. The type of task the vessel performs will determine which Class of system is used.
A blimp on a ship? Sort of. I came across these photos of the newly built Oasis of the Seas testing the feasibility of deploying an aerostat or tethered balloon. The world’s largest cruise ship afloat was conducting sea trials and added testing the feasibility test of a tethered balloon to the extensive 3-day sea trial period off the shores of Turku Finland

Like its sister vessel, Gemini, which set sail on the Tiburon-San Francisco commute in December 2008, Pisces is the nation’s most environmentally friendly ferryboat. Its exhaust is 85% cleaner than EPA emissions standards for Tier II (2007) marine engines and is ten times cleaner than existing Bay Area ferries. Pisces also incorporates innovative measures to protect bay and marine life, including low-wake, low-wash hulls.
Urea…yes…a primary waste product of urine is actually a key ingredient to reducing nitrogen oxides or NOx emissions from diesel engines. NOx is a by-product of combustion, and is the primary cause of smog, acid rain, and the production of ozone. Not only does NOx not take too kindly to the atmosphere, it also does not take kindly to humans. NOx and various toxic by-products from reactions with NOx cause lung irritation, and in high enough concentrations permanent lung damage and biological mutations.
