The term "Project Cargo" refers to the transportation of over sized materials and equipment which are critical components of large-scale infrastructure projects. The logistics involved are almost invariable complex and challenging, in no small measure due to the fact that many of these construction jobs are underway in developing countries. Whether it is a wind farm being built in Malaysia, a coal-fired power plant in China or off-shore energy platforms being installed in the Campos Basin off the coast of Brazil, the values being shipped and the potential for large claims due to physical damage to critical components and the potentially greater cost to the project because of a delay in start-up (DSU) can be daunting. For these reasons, a common feature of project cargo enterprises is the requirement for insurance to be in place before financing for the project can be arranged.
One definition of "risk" is uncertainty concerning loss. Risk underscores every aspect of the projects described above. Managing that risk is the job of skilled professionals working together to minimize the potential for loss while also arranging the appropriate insurance to indemnify the Principal in the event of financial loss should the worst occur.
Project cargo "risk managers" include:
- The assured
- The cargo underwriter
- Experienced risk control personnel (normally an employee of the insurance company directing the efforts of marine warranty surveyors at every step of the transit)
- The insurance broker
The insurance broker's role is critical to the success of the project, since it will not go beyond the initial planning stages unless comprehensive and cost effective insurance is arranged which protects against both direct and consequential losses. The intricacies of even simple Project Cargo Risks require unflagging attention to detail in order to ensure that the complex exposures and huge dollar values at risk are properly protected.
With over 30 years experience as insurance brokers and reinsurance intermediaries in all facets of marine and non-marine insurance, Nausch Hogan & Murray Inc. (NHM) are experts in arranging the insurances needed to completely protect the myriad exposures and "uncertainty concerning loss" which project cargo risks present. As one of the few US-based insurance brokers who are also accredited Lloyd's of London brokers, NHM has access to the global markets which specialize in Project Cargo business. With offices on four continents, the staff includes licensed brokers who are skilled in all areas of insurance, claims experts and average adjusters, admiralty attorneys and licensed merchant marine officers. The combined wealth of experience, innovative thinking and uncompromising commitment to meeting and exceeding the client's insurance needs sets Nausch Hogan & Murray apart from their competition.
NHM takes great pride in continuously providing that level of service to their clients for more than three decades. Experience, expertise and an uncompromising commitment to excellence are the hallmarks of Nausch Hogan & Murray's service to their Project Cargo customers.
Common Issues With Wireless
Everybody wants to get on wireless these days. It is sort of "the thing to do." Funny thing though is, nobody seems to know what they are doing when it comes to wireless. They think they crack open the box plug in some cables and away they go. Well, it isn't really quite that simple.
Issue number one, would be security. You absolutely MUST think about security if you implement a wireless network at your home or office. If you think you are helping out your IT department by putting an access point up in your office so you can move the stuff around your desk more freely, you are sadly mistaken. If you have done this without setting up any kind of encryption, you have just opened a huge back door to your companies network. At home, you may not be so worried. If someone shares my internet, so what? Someone next door could easily setup a phishing scam in the apartment next door, and use your wireless connection for the internet access. Then guess whose door the FBI will come knocking on? That's right, yours. So encryption is a must, I highly recommend using WPA and not WEP because WEP has been proven to be easily crackable.
Issue number two, would be placement. Before setting up anything, you should do a site survey. Walk around your home or office and look for things that can cause interference. Map things out, and take notes. Take a laptop with netstumbler installed and look for other wireless networks in range and see what channels they are on. Some things that can cause problems are:
*Cordless Phones/Microwave Ovens: These devices operate at 2.4Ghz, which is the same frequency Standard 802.11G/N routers use. Since they both operate at the same frequency, they will interfere with each other's signals.
*Concrete Walls: Concrete causes a problem, not because of the thickness or the re-bar in it, but because of the water in the mixture. The magic thing about concrete is that it never stops curing, and the water in the wall can cause signal loss.
*Pointing your antenna: Some people think that pointing the antenna is self explanatory, but it isn't. You can't point your antenna like you point your finger because the signal coming off the antenna radiates from the sides of the antenna, not the top.
*Wireless Channels: By default, almost all routers come pre-configured to use either channel 6 or 11 (if I'm not mistaken). Find out what channel the surrounding networks are using and select a different channel. As mentioned above, Netstumbler for Windows works well for this as well as kismet for Linux and Kismac for MAC.
*Chicken Wire: That's right, I said chicken wire. I didn't come up with this one myself. I had a wireless class at college, and my professor told us about chicken wire. Chicken wire is used in some houses to either hold in insulation in the walls, or is used when putting up plaster walls. The holes in the chicken wire are not large enough to allow the sign wave of the wireless signal to penetrate the wall and thus creates a Faraday cage of sorts.
Issue number three, compatibility. Almost all wireless devices come with the WiFi logo which is supposed to indicate some sort of standard. It suggests that if you have a Belkin router, your Linksys wireless card should be compatible. Well, 9 times out of 10 that is true, but every once in a while there is that 1 time where it is not true. It is almost always best practice to stick to the same manufacturer. If you are a D-Link person, stick with D-Link, if you like Linksys, stick with linksys and so on.
Issue number four, Firmware. The manufacturers of your equipment frequently come out with firmware updates for their products. If you notice issues with your router or card, look on the manufacturers website for a possible firmware update. Lots of times, the update can correct the problems you are having.
Issue number five, loss versus gain. Every time you have to send a signal down a wire you have loss. If you have a long cable going from your modem, CSU/DSU etc going to your router there will be loss of signal. The longer the cable, the more loss. Likewise, the air creates signal loss as well. The farther you are from the antenna, the weaker the signal. On the flip side, whenever you have an antenna, you have gain. Every time the signal comes out of the antenna, or is received by an antenna there is a little bit of gain in the signal. So what does that mean to you? Shorten your cables if possible, and buy higher gain antennas for your routers if you need the signal to travel longer distances.
