sea. The concentration of Aqua-Col D in the mud<br />
is 3.5% in volume. That product is essentially<br />
Glycol. We also have Lubricant additive that has<br />
been added to the mud earlier (also Yellow SFT<br />
color coding) at a concentration of 2% volume.<br />
That WBM is dumpable but that event is<br />
considered as a spill due to the fact that it has<br />
been uncontrolled.<br />
After landing of the 18 3/4" WHRT for BOP test,<br />
it was discovered a drop in the trip tank.<br />
Investigation showed that the wear band in the<br />
upper (primary) packer on the slip joint was<br />
laeking. The air pressure on the packing element<br />
was 10 bar. A total of 800 ltr of waterbased 1,41<br />
sg mud was lost to the sea.<br />
The closing pressure was increased to 22<br />
bar and the leakage stoped. Later the<br />
pressure was reduced to 15 bar with still<br />
not leaking<br />
Tabell 8-2 gir en oversikt over akutt oljeforurensning i rapporteringsåret. Tabellen viser at<br />
det er registrert to utslipp av denne typen i 2008<br />
