MMC SD-2/W/40M Cargo Liquid Sampling & Tank Bottom Dryness Checking (Hand Dipping) device

The IMO Requirement on Tanker Safety and Pollution Prevention, 1978 – Resolution A.446 (XI) 4.4.4.states “means such as level gauges, hand dipping, and stripping system performance gauges as preferred to in Paragraph 4.4.8. shall be provided for checking that the bottom of cargo tanks are dry after the crude oil washing. Suitable arrangements for hand dipping must be provided at the aftermost portion of a cargo tank and in three (3) other suitable locations unless other approved means are fitted for efficiently ascertaining that the bottom of every cargo tank is dry.”
So the simplest method for checking dryness of tank bottom is to lower a Dip-Scale to the tank bottom and read-out the level of remaining oil adhered on the Dip-Scale.

“MMC” Cargo Liquid Sampling Device Model
“SD-2/W” can be used as the tank bottom dryness checking [hand dipping] job, to fit the Dipping Scale Model “DS-200S” at end of the Graduated Tape instead of the Sampling Bottle “05L43”.
This arrangement can be used on Tank Gauging Station [Hand Open/Close Type Vapor Locks] Model. “C-50″(or F-50) and/or the Tank Bottom Dryness Checking Station Model “D-25”, without releasing dangerous vapor into the atmosphere.
