Algae Biodiesel

What about algae biodiesel. Is fully renewable,
does not affect the food channel and eats co2?

CARB and Sen. Boxer

Does anyone think it might be a good idea for Sen. Boxer to take a trip on perhaps Pasha's Jean Anne or one of Matson's diesels and see what it is like in the real world. Where do these people think they can muster up 0.1% sulfur fuel in the quantities needed. I think everyone is for the environment however, we must also take a practical approach and involve those who are on the operating end of this system in the process.

Tschuss!

Miss River Collision

Better be careful sending those boys from up north down there to investigate. Those boys have a different way of doing business on the bayou. Does seem strange regardless of unlicensed operator aboard the towboat how a knowledgable river pilot can "T" bone a barge. No excuse for all this with the exception of money and working conditions. Unfortunately the ones to really suffer in this case are the numerous species of wildlife in the area.

Cat Fines/Separators - Tech Tip

Try again to post the entire tip:

There have been many instances of damage to fuel injection equipment with resultant blame placed on the fuel. One must remember that fuels though meeting ISO specifications of 80 ppm or less may still be problematic if the abrasive particles are small

Scrubbers

Aside from the fact that tankers for years have employed scrubbers in the Inert gas systems with no one taking note to any environmental impact most new scrubbers for diesel exhaust are designed as either closed loop using fresh water or have an eflluent processing system to remove particulates and pollutants from the overboard stream. Such processing systems will apply to both fresh and salt water scrubbers. While there are not many out there yet the effluent processing system and logictics of disposal of the resultant sludge may pose the biggest challenge to the engineers aboard. By far the scrubber is however, the simplest method of removing both sulfur and particulates. Check out Wartsila's website or Krystallon for more info on the new systems.

Scrubbers

A story surfaced a while back on a scientific study that showed that the waste water from stack-scrubbers, if discharged into the sea, might then cause big-time CO2 releases from the sea. Anybody out there know more about this?

Another view

Good points regarding Marpol and the slow response from the US however, there are other alternatives to burning more expensive low sulfur fuels of questionable quality such as scrubbers for vessels below 20Mw. When fuels are blended to achieve lower sulfur levels there are often less than desirable ignition and combustion properties in the resultant blend.

I do like the idea of a national emissions control area rather than individual state cases such as California.

One point to remember in todays era of rapid growth and constant stream of new people at sea. Before we rush into the applications of emissions controls systems be they scrubbers, SCR, charge air humidification, emulsions, etc. we must first ensure that each and every vessels plant is performing to it's designed parameters. Should this not be the case the good intentions of exhaust after treatment will result in a significant increase in operational issues for shipboard staff.

As to Carbon Tax and emsissions trading don't know eneough about the subject to comment.

The USA and MARPOL Annex VI

Having recently attended maritime forums in both the US and Europe I feel quite embarrassed by the US' delays in the ratification and implementation of MARPOL Annex VI. The time has come for the following positive actions:

1. Ratify and implement Annex VI

2. Take a more "active" position and participation in IMO and the ISO.

3. Implement a nationwide SECA calling for use of 1.5% sulfur HFO in US coastal transit waters and use of MGO/MDO while in port. Ports/vessels fitted with cold iron capability might receive special incentives. This SECA must be under the administration of a competent agency for both implementation and most importantly enforcement. EPA perhaps?

4. Require "all" US bunker fuel suppliers to provide every vessel with "properly excecuted and complete" Bunker Delivery Notes.

5. Task the EPA to develop legislation to identify clearly to all concerned parties, a list of quantitive values of banned substances in marine fuel oils and require any purveyor of marine residual fuel oils to provide a "statement of origin identifying by an accepted UN code any components used in the blending of residual marine fuels" to every vessel at time of delivery. No more "mystery brews". The risks to the environment and marine safety have been documented in far too many vessel machinery casualties. To clarify - one case is too many.

6. Implement marine fuel delivery and sampling standards/legislation along the lines of the Singapore standard. Require in such legislation that the binding sample in any fuel related matter is the one taken at the "point of custody transfer" by a world maritime community sampling method and that the suppliers representative may no longer opt out of witnessing such sampling or signing of delivery documents.

While we no loner deploy a major commercial fleet in world commerce there is no excuse for not projecting a positive professional image amongst the worlds maritime community.

Let's see what the oil companies and the lobbyists can do with these.

Safe sailing!

Talk about Environmental Image

Both OSG and Chevron continue to operate antiquated gas turbine vessels in the Jones Act trades that consume something to the tune of 10-11 gallons a minute of Marine Gas Oil while underway and only slightly less while engaged in cargo operations. It would seem such large players would do all they can to improve their environmental footprint. And Chevron has no excuse as they are earning enough money to replace those relics even in US yards. They were a great idea back in the day however, environmentally irresponsible today.

Stepping Back in Time

So much work has gone into developing today's high output electronically controlled engines to break the 100k horsepower mark combined with remarkable naval architecture to develop hull forms to reach remarkable speeds in the container industry. Designs for 20K+ TEU ships are on the boards and power is already a concern.

Today we see fuel prices that are beyond comprehension and talks of reducing large containership speeds to as little as 11 knots. If we are to maintain the lifeline of "essential" goods in world commerce and at the same time do all we can for the environment it would appear that a long hard look has to be given to nuclear power for such giants. The others, bulkers, VLCCS, and the like can live with smaller plants and slower speeds. The economics of the "large" containership relies on speed.

I hope something can be done to keep these ships at speed as it is a shame to see all the hard work that went into engine and hull design go to waste due to greedy oil barons.

The Environment

We have to do all we can to help the environment. Scrubbers now appear to be "in" as long as th effluent treatment systems and subsequent logistics thereof prove to be reliable and hopefully the US will soon ratify MARPOL and institute a nationwide 1.5% sulphur cap. Scrubbers can reduce both SOX and particulate matter. All we need now is short sea shipping using fast self propelled feeder vessels to reduce the number of trucks on the roads. The stumbling block it seems to feeder vessels here is the prohibitively high cost of construction in US yards. Perhaps our most productive yard AKER can work with someone like DAMEN to build one fo their standard feeders at a realistic cost.
