STATEMENT OF WORK

Contractor to supply necessary design and specification information to both ABS and

USCG to gain approval for the upgraded purifiers. Purifiers must have OEM approval for ABS and USCG-MSC. Approved drawings to be used as a guide for the installation of the new purifiers and will be considered a deliverable.

Contractor to supply all necessary labor, material, rigging and transportation to supply and install new upgraded purifiers aboard TS Golden Bear including all electrical, mechanical and controls plus the necessary piping and fittings to connect to the old services from the old purifiers

Contractor is responsible for removing any interference to allow access for rigging skids into the engine room and into place on top of the abandoned sludge tanks below each of the existing purifiers. Reattachment to as found condition is required as noted in the

Terms and Conditions for all interference removal

The specific locations and arrangements of the new purifiers are as follows:

1) Lube Oil Purifiers

Located in the lower Port engine room adjacent to the watertight door between the engine room and the auxiliary machinery room
