What to Keep In Mind When It Comes to HVAC
Heating, ventilation and air-conditioning (HVAC) systems keep you cool in the summer and warm in the winter. Thatâs the simple explanation. It does not encompass the complexities of what needs to be done to assure the all-important continued conditioning of the air in your vessel.The systems installed in vessels today can run the gamut from static vent scoops that force air into an area to a raw water chiller system whose workings take up the same amount of space as a 40-foot cargo container. The equipment is there to meet the need of the end user.
HVAC: Three Challenges to Challenge Engineers
âOn the 27th of July, 1850, I sailed from Baltimore in the ship Nonantum, of Boston, (Bates, master,) bound to San Francisco. In the ship's hold was stowed 1,050 tons of coal. The second morning after the commencement of the storm, smoke had been discovered between decks. The alarming truth instantly flashed upon our minds. The gas that originated from the coal had generated fire. They next proceeded to close the hatches, and caulked every seam tightly, in the hope of arresting the progress of the fire it was impossible to extinguish.â -Incidents On Land and WaterâŚ
Reverse Osmosis and the New Dawn of Marine Desalination
Todayâs desalination plants are rugged, durable and highly automated to meet the demands of operators and the crew, enabling them to meet schedule and mission with ample potable water production.In the days of old, marine distilling plants â then mostly steam â relied on archaic flash evaporators, which used steam to heat, power an air ejector, and ultimately create a vacuum whereby seawater would flash or boil and ultimately be distilled. The process would often occur over two stages and what did not flash would be pumped overboard as brine. Times have changed.
MAN Cryo LNG Supply System For Norwegian Ship
Marine LNG systems manufacturer MAN Cryo is to deliver an LNG fuel-gas supply system to Norwegian shipowner Egil Ulvan Rederi. The new system will be installed on a multipurpose palletized-cargo and refrigerated l lift-on / lift-off (LoLo) vessel which will be built by Multi Maritime in accordance with an MM85CC design at Tersan Shipyard in Turkey. With a length of 86 meters and a width of 19.5 meters, the 3,500 dwt vessel is expected to be delivered late next year.MAN Cryo will be responsible for building a verticalâŚ
Wärtsilä's FW System Yields One TPD Fuel Savings
The technology group Wärtsilä has successfully installed its Serck Como Horizontal Tube Evaporator (HiTE) fresh water production system onboard the pipe-laying vessel, âLorelayâ, owned by offshore contractor Allseas. This is the first commercial installation of this Wärtsilä innovation. The retrofit project produces clean water for technical applications and human consumption, and has led to fuel savings of as much as one ton per day.The unique aspect of the Wärtsilä HiTE is that it is a multi-stage evaporator specifically designed for small to medium capacities of 30 to 150 tons per day.
Fire Breaks out on USCG's Polar Star
It seems the U.S. cannot do enough to fast-track the construction of its new icebreaking fleet, as the USCG announce last night that the 150-member crew of the U.S. Coast Guard Cutter Polar Star fought a fire at approximately 9 p.m. PST Feb. 10 that broke out in the ship's incinerator room about 650 miles north of McMurdo Sound, Antarctica.After initial response efforts using four fire extinguishers failed, fire crews spent almost two hours extinguishing the fire. Fire damage was contained inside the incinerator housingâŚ
SkimOil's Next Gen MarineVAP Evaporators With New Safety Features

A New Breed of Tug
When markets expand niches are created, goes the logic. For builders of tugs, that market is âfloating gasâ and the expanding use of liquefied natural gas, or LNG, as a fuel. In support of LNG, thereâll be more oceangoing tug duty â the new floating storage and regasification units, or FSRUs, mean busier LNG carriers, and LNG cargo owners have an interest in tug escorts that share their âcarbon footprintâ. Still, new emissions rules offer ways to keep using refinery products, and the work of master tug designers suggests the new breeds of tugs are about more than fuel.
Dual-fuel Escort Tug for Østensjø Rederi
The first of three new dual fuel RAstar 4000-DF class extreme escort tugs, the Dux, has been delivered to Østensjø Rederi AS by Spanish shipbuilder Astilleros Gondán S.A. Designed by Robert Allan Ltd., the 40.2 meter vessel is the first of a three boat order from Østensjø for severe weather operations at Statoil's Melkøya LNG Gas terminal at Hammerfest in the extreme north of Norway. These escort tugs will conduct approximately 300 LNG ship escorts annually, assist with berthing operations and will be maintained in readiness for emergency services such as long line towingâŚ

APM Slashes Out-of-Service Days
Removing a 132 metric ton engine from an 11 deck luxury cruise liner whilst itâs in-service may sound impossible, but thatâs exactly what marine engineers Atlantic Pacific Marine (APM) did in February. The company teamed up with wire sawing experts Drillcut (UK) Ltd. to cut one of Disney Wonderâs Sulzer ZA40S engines into 32 separate sections en-voyage. The sections were then lifted out and off loaded, enabling ultra-fast engine replacement once the liner had dry docked in the Grand Bahama Shipyard. In all, the innovative process saved six dry docked days.
