Hourly activities:
00:45 - 01:15: Performed TBT with all involved personnel for rigging up cement spool onto XMT
01:15 - 02:15: Removed hatch on well f-1 c. Meanwhile altus prepared and lowered hoses down to moonpool for local control of HMV and DHSV.
02:15 - 02:30: Installed scaffolding around hatch. Meanwhile barriered off area on XT deck.
02:30 - 03:45: Verified no pressure on KWV prior to rigging up manifold rigged up manifold on KWV. Installed bleed off line as per dop.
03:45 - 04:30: Altus hooked up hoses for local control of HMV and DHSV. Meanwhile rearranged hoses in moonpool for over head crane to have clear passage.
04:30 - 06:00: Attempted to leak test bleed-off manifold against closed KWV with test pump, no go. Attempted to re-test, no go. Found leaking check valve on manifold. Replaced check valve and attempted to pressure test line-up to XT cross, no-go. Found newly installed check valve also leaking. Replaced check valve with lo-torque valve.
06:00 - 06:30: Leak tested bleed-off manifold, OK.
06:30 - 07:00: Opened HMV and MMV, 29bar above DHSV. Started to bleed down pressure above DHSV through KWV to closed drain.
07:00 - 09:15: Continued bleeding off pressure above DHSV. Bled down to 0,3bar. Closed HMV and confirmed no pressure in XT cross. Removed bleed off line and removed tree cap.
09:15 - 09:45: Removed studded tree cap connection from XT and lifted same away with tugger.
09:45 - 16:15: Studded bolts found to be loose on CMT manifold and spool. Lifted cement manifold with gantry crane rigged up high torque equipment and torqued up studs correctly, checked all other studs. Meanwhile installed split hatches over well f-1 c. Test ran shakers.
16:15 - 16:30: Performed pre-job meeting for installing the cement spool onto XT.
16:30 - 17:15: Lifted cement spool and landed off on XT according to simops procedure.
17:15 - 18:00: M/u studded flange connection to XT. Meanwhile prepared cement hose
18:00 - 18:45: Installed smaller split hole cover around cement spool on hatch deck. Rigged up cement hose to cement spool. Installed safety slings.
18:45 - 19:00: Cleaned and cleared moonpool area.
19:00 - 21:30: Built scaffold in moon pool around cement spool for open and closing the lo-torq valves, and to install the drain hose on top. Meanwhile altus re-routed and re-installed control hoses for local control of HMV and DHSV. Hook up contingency hose from bleed-off manifold to overboard.
21:30 - 22:15: Continued rigging up hoses to cement spool. Meanwhile scaffolders continued to build scaffold in moonpool. Cementers prepared fluid for volume test of line to moonpool. Altus tested and checked hose connections for local control operation of HMV and DHSV.
22:15 - 22:45: Altus installed hose to closed drain on top of cement spool.
22:45 - 23:00: Performed pre-job meeting for pressure testing the cement spool
23:00 - 00:00: Prepared cement unit for cement operation and volume test to moonpool.
