LAB OFFICER'S REPORT

General Leg Information

Expedition 376T Transit commenced on July 5, 2018 in Auckland, NZ with the boarding of the marine specialists. The vessel sailed at 13:00 on July 7, 2018 for Subic Bay, Philippines. A dry dock and tie up period are planned. The vessel arrived at the Keppel shipyard, Subic Bay on July 25 commencing 378P Subic Dry Dock.
The vessel left the dry dock on August ## and went pier side at the Keppel yard to finish up various repairs.
During the shipyard period only one shift was staffed. While the ship was in the dry dock and unlivable the staff resided at the Lighthouse Marina hotel in the SBMA.

LAB STACK

The areas of the lab stack, which were accessible, were stripped of all removable equipment at risk of being taken. This included all public area TVs, computers and supplies.

Bridge Deck

Offices and Conference Room

The bridge deck offices were locked during the Keppel period when unattended. Loose items removed and stored in BSCI.

CORE Deck

Securing Lab

A series of plywood walls were built on the transit to Subic Bay. This allowed the core lab, Paleo prep and cutting room/core entry and down hole lab areas to be secured. One door is placed in the core entry wall to provide access to tools and an air conditioned space.
The water leak in the overhead piping above where the core lab printer sits was repaired by dry dock personnel.

Projects

Three failing floor patches were chipped out and repaired in preparation for painting.

Catwalk

Weather wall removed and stored in the Pallet Stores. The walls and hardware are above the core boxes. The windows and frames are in the batcave over the small stairs to the lower tween.
All loose items removed and placed in the splitting room.

Paleo Lab

The paleo Lab was used to store the conference room tables and various IT items.

P- MAG LAB

The SRM was shut down and all items in the lab disconnected from power. Plastic sheeting was placed over all equipment to keep out dust.

Microscope Lab

The microscope lab was used for storage of the conference room chairs. All electronics were disconnected from power. A barrier wall was placed across the entrance of the lab and the forward door locked with a padlock.

Focsle Deck

M-BIO Lab

The incubators, benches and desks were removed from the aft end of the MBIO lab. The floor was repaired by the 3^rd party flooring crew contracted by Siem. The area was painted and cabinets reinstalled

Chemistry Lab

 

Radvan

Equipment in the radvan was secured or removed. The protective covers were installed on the two external A/C units.

Conference Room and Offices

Floor level furniture was removed from the Conference Room, Pubs Office, and Curator/Education Office in preparation for carpet replacement.
Three A/C units were installed in the Conference Room by the Siem crew during the transit and connected to the chill water lines during the dry dock.

XRAY LAB Report

Nicolette Lawler 

Summary

XRD samples from X375 were run, the pXRF underwent some testing, and the lab was shut down in preparation for dry dock.

XRD

All samples from X375 were run and sent to shore to be added to the database and to Mike Underwood for analysis. No problems were encountered with the D4.

D4

No issues were encountered. Water was drained from the system in preparation for dry dock. When the D4 is turned on again for the first time the HASKRIS should get filled with water and a little vinegar and allowed to flush through the D4 for a bit, then drained again and filled with regular water.

HASKRIS

I did not see any leaks during the transit. The water level remained constant in the tank. Once the ship got into warmer, humid climates the chill water lines started condensing.

XRF

The pXRF had some error warnings during X376. I ran the instrument for 2 days, ~800 measurements, but did not encounter any problems. As time permits more extensive testing should be done.

Chemistry Laboratory

Aaron Mechler

Summary

The instruments in the chemistry lab were not used during this tie up. All instruments and pc's were shut down. Everything in the lab was unplugged. All refrigerators and freezers were defrosted.
The desks and countertops in MBIO were removed. The desks to upper tween, countertops to thin section. All supplies that had been stored in the cabinets are in the GC2/TOC area and in hood F4. The incubators are in the cold room. The incubator in front has the MBIO chemicals inside that had been stored in the incubators. Chemicals that were stored in the cold room freezer were removed and are currently in hood F3. These may end up needing to be disposed of.
All reagent bottles in the big fridge that are used for ICP and spec were emptied and washed. The cabinets and drawers these are normally stored were already full so they were placed in boxes and are on the floor by the IC. The brown glass bottles from this were placed in hood F3.
Covered instruments and pc's with plastic to protect against any possible dust from the MBIO floor work or from water condensation when AC is turned back on.

Balances

Not used, unplugged.

Carver Presses

Not used, unplugged.

Cary Spectrophotometer

Not used, shut down and unplugged.

CHNS

Not used, shut down and unplugged. The plug and outlet this was plugged into was difficult to reach. I was able to unplug it without moving the instrument but it may be more difficult to plug back in.

Coulometer

Not used, unplugged.

Freeze-drier

Not used, unplugged.

Gas Lines/manifold

All gas switches and bottles in the lab to all instruments were turned off. The gas tanks on upper tween were closed and the lines were disconnected from the tanks. Both the Argon and Helium tanks that had currently been in use are lowish (<500 psi).

GC3/NGA

Not used, shut down and unplugged.

IC

Not used, shut down and unplugged. The Anion and Cation columns were removed and capped. They were placed in the top metrohm supplies drawer. Did not empty reagent bottles

ICP

Not used, shut down and unplugged. Did not empty the bottle containing the nitric acid rinse.

SRA

Not used, unplugged.

Water system

RO and nanopure systems were shut down and the water valve under the sink was closed. Sinks were covered with plastic tarp to prevent use.

TOC

Not used, unplugged.

ET Report

UNDERWAY GEOPHYSICS LAB

Summary

Navigational data was collected on the transit from Auckland to Subic Bay. The magnetometer cable had been removed and rough seas at the beginning of the transit made running the bathymetry system pointless.

Equipment Performance Summary:

WinFrog

Was run on transit to Subic Bay then shut down for the dry dock period.
378P2
Winfrog was restarted and tested during Tie-up in SBMA (~07-October, 2018.) The signal from both GPS and Gyro seemed OK. Test data were recorded.

Trimble GPS

Was run on transit to Subic Bay then shut down for the dry dock period. No issues were encountered.

Bathy 2010

The system was not run on transit to Subic Bay and was shut down for the dry dock period.
The system was tested and pinged during the Typhoon evacuation.

Magnetometer

The magnetometer was not towed on the transit as the cable had been removed prior to the transit.

Data Backups

Navigation Files for 346T are on Winfrog 1
C:\EXP NAV DATA/EXP376T/

FANTAIL

Summary

Special projects

The magnetometer winch was greased, lubricated and covered. All the other equipment on the fantail is covered in their tarps to protect it from sandblasting grit during the dry dock period.

Sonar Dome

The sonar dome was removed while the vessel was dry in the Keppel Subic dry dock.

Preparation for removal of the sonar dome
