comments: Picked up CART stinger 0,5 m above wellhead. Installed cover on subsea wellhead with ROV. Washed template through drillpipe and CART tool to remove cuttings. Cavitation in string made it hard for ROV to grab onto pipe. Re-positioned ROV to right below CART stinger. Stepped up rate to 4500 lpm and washed template while moving pipe with ROV. Inspected wellhead cap and template with ROV.
