  1. No, I don't dispute that Carnival, in particular, has a culture of not following environmental laws, no gray areas there, but I will also say that I witnessed first hand how a company, NCL, could and did turn its entire corporate culture around with regards to environmental compliance. I've never advocated for the cruise lines to receive federal money, and still don't, but the whole mention of the environmental violations is pure tabloid journalism. I would like to research how many companies that do receive federal money have had environmental fines in the past. But, what I am against is environmental folks stating things like "tons of oil contaminated water", when due to the nature of the violation, no one can say whether a single drop of oil was discharged, or whether tons of oil were spread in a miles long sheen, since the violation was for discharging around an oil content meter. I routinely discharge water that my oil content meter shows as having less than 1ppm (15ppm is the legal limit), and this is water straight from our engine room bilges. So, while legally it is correct that any water in an engine room bilge is "oily water", in reality, it may have absolutely no oil in it.
  2. To qualify for the "bail out", any company needs to be incorporated in the US, and if incorporated in the US, it must have the majority of it's employees in the US. Companies like Ford would not qualify on the majority of employees qualification. While I am probably the largest advocate of crew rights on this site, it really gets me when folks complain that the crew are not getting "the wage they deserve", or the "correct" wage, or "a fair wage". Believe me, what the crew earns, and it may well be not enough to interest US citizens, or even be enough to "survive" in the US, they are earning upper middle class incomes in their home countries. And, before you cast stones at the cruise lines, know that the minimum earnings for a cruise ship crew are about $16-17k/year, or about the US federal poverty guideline, for a two person household. How many full time employed people in the US are living below the poverty line? 2.6 million. These are US citizens, employed by US companies.
  3. Well, it is an environmental group making the statement. They also stated that Princess was fined for " illegally dumping oil-contaminated waste", when in fact there is no evidence that any oil was sent over the side, just that potentially oily water was processed in an illegal manner. But, that doesn't sound as environmentally unsound as their statement.
  4. Well, they'd have to measure you to determine your volume before and after, since tonnage does not equate to weight. That could be even more profitable.
  5. I don't know the life cycle maintenance cost of airplanes, but with ships, the cost vs age is an exponential curve, and the curve turns to the vertical (more cost/year) at around 15 years, and goes way high with each ensuing year. Looking at the big 5 lines, Carnival has 36% of the fleet over 20 years old, HAL is 28%, RCI is 27%, Princess is 22%, and NCL is best with 12%. While there is a lot of outcry here on CC over the demise of the smaller ships, these older, smaller ships are going to be the ones to go, as they will be easier sells, and the capital invested in them is less. As to who would want these ships, there are other cruise lines out there that operate on different business models and different profit margins, like Celestyal, Cruise and Maritime, Thompson, P&O, Pullmantur all operate older vessels than the mainstream lines wish to operate.
  6. Some of that was simply scheduling. Some was to allow for maintenance, since the propulsion systems had less redundancy than today's ships. Some was fueling: coaling was very slow and labor intensive, and the oil bunker industry was not as advanced, and the ships used vast quantities of fuel to make their speeds. For roughly the same number of passengers, the SS United States needed 180Mw of power, while the QM2 needs only 80Mw. Some of that was cargo, the liners all had small cargo holds forward, and loading was crate by crate, and some was mail (Cunard), and that required a regular, timed, service.
  7. While nothing is 100% effective, most commercial sanitizing agents, like the Virkon that cruise ships use when dealing with noro, have effective contact times of a couple minutes for a 90-95% reduction in bacteria/virus. Fogging is a particularly effective means of application, especially when dealing with soft surfaces like the carpeting in an airplane.
  8. They will get underway, steam around a bit to provide heat to the water makers, and then go back to anchor. Cruise ships are generally provided with more watermaking capacity than is needed, since you can't run it all the time, and without pax, you are using less than 1/3 of normal consumption. Onboard tankage would be over a couple week's worth of water for crew only.
  9. Even using heat recovery (or in this case, "cold" recovery) technology, this will increase fuel costs dramatically.
  10. 1. Generally, no, but you can't just anchor anywhere, there are designated areas. 2. Generally, yes, but it depends on the contract the company might make with the port authority 3. As SeaDog says, smaller crew (20-30), so only use about 8-10 tons of water daily. Gray and black water not an issue, as long as the treatment plant is working. Though there are some restrictions in the US when you get within 3 miles of shore on types of discharges. Also, to discharge bilge water (through an oil/water separator), you must be "underway". 4. No, the ship pumps sea water into the distillers. But, as noted, you must be 12 miles offshore to make water. Also, if you are using a flash evaporator, rather than a Reverse Osmosis, water maker, you need a certain amount of "waste heat" from the engines. The hot cooling water from the diesels is cooled two ways (think of the radiator on your car): one is via a cooler to sea water (wasted heat), or the other is to heat sea water in a flash evaporator, causing it to boil and then can be condensed as fresh water. There are ways to make water at anchor with a flash evaporator, using the boiler for heat, and RO units don't need heat, but if you are running your sewage treatment plant at the same time you are taking sea water in to make drinking water, there is a very good chance of bringing contaminated water into your water makers.
  11. Those restrictions on using "public transportation" (including airplanes) after a cruise are pretty much for the current cruises that have yet to finish and disembark passengers (yes, there are still some out there), mostly the two HAL ships in Florida. There is no indication that these are going to be permanent restrictions. I doubt that there will be a full day between cruises, nor do I foresee any major changes to cleaning protocols. If there were to be a "null" day between cruises, while your price might not go up, you would only get a 6 day cruise for the price of a 7.
  12. The open central area of the Oasis class ships, and any non-totally enclosed areas (i.e. open pool decks, even surrounded by glass, and sports decks) are not included in tonnage calculations.
  13. I think a lot of this is due to the backlash against the large ships in certain ports and areas, and the new restrictions on arctic areas, and I think these may have a brighter future than the large ships, in the short term. Until Carnival's Chinese flag ships (which can avail themselves of coastwise Chinese itineraries, and are truly a part of the Chinese economy) enter service, I don't think the China market will be fully exploited.
  14. No, they are not ill, they just cannot fly. Conditions like COPD or DVT don't mean you need hospitalization, but because you have COPD, or have had a DVT in the past, you are not supposed to fly, per your doctor.
  15. The worst part of the "apology" is this: "I believe, precisely because he is not naive and stupid, that he sent his alarming email with the intention of getting it into the public domain in an effort to draw public attention to the situation on his ship. I apologize for any confusion this choice of words may have caused,"
