Rules For Barge Sealing (continued)

Marine Corporation (AUMC) of

Saugus (Boston), Mass. With a little practice, these tapes are almost as easy to use as a sounding line for measuring water depths. The tapes are calibrated in both inches and centimeters. Temperature is dis- played either in degrees, Fahrenheit or Celsius.

Barges routinely load cargoes for multiple destinations with specific volumes for each customer. To measure these volumes, "step gaug- ing" is used. The ullage sensor bob is positioned in the tank at a level determined from tables on board, and cargo is unloaded until the liq- uid surface falls to the level of the bob.

The gauging tape is installed on top of a ball valve by means of a quick connector. The gastightness is guaranteed up to 3 psi tank pres- sure, thus protecting the operator and the environment from any haz- ardous substances such as benzenes and toluenes.

Sampling containers are also available which can be used through the same 2-inch valve used with the measuring tapes and probes just de- scribed to provide removal under vapor-tight conditions.

A more sophisticated system is the high-level alarm and overflow

PILGRIM®

PROPELLER NUTS with acme threads eliminate the problems of galling and seizure and guarantee a secure grip well in excess of full load torque in all sea water temperatures for keyed or keyless propellers.

PROVEN on thousands of installations on cargo ships, tankers, naval vessels and submarines throughout the world.

Pilgrim Nuts are also used on inboard tailshaft couplings, rudder stocks and pintles.

This equipment utilizes acid resistant stainless steel floats in contact with the liquid cargo. The floats carry magnets which activate reed switches when preset levels are reached. Audible and visual signals are presented by an alarm panel to the operators, either on board or at remote locations such as the termi- nal office.

In addition to warning with alarms, the panel can also be pro- grammed to activate valves or pumps which will counteract the overflow situation.This is the same type of equipment which has been used on oceangoing chemical car- riers and tankers carrying LNG and

LPG since 1966.

Lisnave Wins Contract

For Reactivation Work

On Esso-Owned Tanker

A contract for reactivation work on the 450,390-dwt ULCC Esso Me- diterranean, last of the large Esso- owned tankers to be reactivated this year, has been won by the Portugese yard of Lisnave. The vessel, which has been laid up since 1983, has been towed to Norway, where it is expected to be in the shipyard for at least four weeks. A similar operation on the 449,934-ton Esso Caribbean was recently completed by Lisnave.
