White House Endorses Unlimited Liability Cap For Oil Spillers

Democrats in Congress and officials in the White House are making yet another major push to pass legislation to make the liability for oil companies involved in damaging spills unlimited.

On Monday evening, the White House confirmed that it favors the most recent piece of legislation that would drop any numerical ceiling to the amount of money an oil company like BP would have to pay for economic damages caused by a spill. Currently, the cap is $75 million. cont.....

LMRP on BOP חדשות ישנות מהמפרץ

לפני יומיים המחבר שידוע בכינויו LMRP הורכב בראש ה-BOP לאחר מבצע מורכב של של חיתוך המגביה וצינור המקדח בתוכו המבצע עבר בהצלחה והמיתקן מעביר כמויות של נפט וגז לאונית הקידוח מעליו כמה? שאלה מצויינת שאין לה תשובה בהודעות של bp. במקביל עומדות להתחיל העבודות לגשור איים ויצירת מחסום חול מסביב לדלתה של המיסיסיפי. ישנה מחלוקת בקשר לרעיון
BOP המתקן שמחובר לראש הבאר ואמור היה למנוע התפרצות של נפט וגז אבל כשל כידוע
LMRP Containment Operation Deployed
Release date: 04 June 2010

BP announced today that oil and gas is being received onboard the Discoverer Enterprise following the successful placement of a containment cap on top of the Deepwater Horizon's failed blow-out preventer (BOP). This follows the cutting and removal of the riser pipe from the top of the BOP's lower marine riser package (LMRP).
It is expected to take one or more days for flow rates of oil and gas to stabilize and it is not possible at this stage to estimate how much oil and gas will be captured by this containment system.
All of these operations are complex, involve risks and uncertainties, and have to be carried out by remotely operated vehicles (ROVs) at 5,000 feet under water. Systems such as the LMRP containment cap never before have been deployed at these depths and conditions. The containment system's efficiency, continued operation, and ability to contain the oil and gas cannot be assured.
Preparations continue for the planned enhancements to the containment system as announced on June 1. Work continues on the first relief well, which started on May 2, and the second relief well, which started on May 16. Both wells are still estimated to take around three months to complete from commencement of drilling.
Louisiana Begins Controversial Engineering to Ward Off Oil Spill
Erik Stokstad Science 4 June 2010:
Regardless of when BP finally manages to stop its undersea gusherfrom the Deepwater Horizon, a massive slick will likely remainin the Gulf of Mexico for some time. With public officials desperatefor action, the magnitude of the disaster—the largestoil spill in U.S. history—has inspired an unprecedentedand untested idea for combating it: an extensive sand trap.But scientists are dubious about the project's chance of successand say it could even jeopardize long-term restoration of Louisiana'swetlands, which have been disappearing for decades.

6.4 Mangroves 

Ecology 

Mangrove communities are diverse assemblages of trees and shrubs that are found fringing 

much of the tropical and sub-tropical coastline of Australia in sheltered areas, with the most 

extensive communities found in the tropics. The mangrove flora of Australia is one of the most 

diverse globally and these are highly productive systems. Mangroves act as an important buffer 

between land and sea, filtering terrestrial discharge, decreasing sediment loading of coastal 

waters and maintaining the integrity of coastlines. They are also valuable for their role in 

nutrient and carbon cycling. Mangroves act as a nursery and breeding habitat for marine species 

such as fish, crabs and prawns, including many commercially valuable species, and they also 

support a variety of terrestrial species such as bird populations.  

Implications 

Mangroves are under threat from coastal development, river catchment modification and 

pollution. While adapted to cope with salty conditions, mangroves thrive in areas where there is 

plentiful input of fresh water. Sea level rise is now considered a major threat to mangroves; they 

grow on shorelines with a low profile, thus, a small rise in sea level could inundate large areas 

of mangroves. Increases in atmospheric CO2 may enhance mangrove growth, but this will 

depend on other factors such as nutrient availability and salinity levels. Given the role of 

mangroves in coastal systems, conservation of mangroves should be considered a priority 

management strategy in response to climate change threats
