MIL-HDBK-1005/9A
(4) Details of these systems are given in Oil
Pollution Abatement Systems on Surface Ships, S9593--BF-DOT-010,
Naval Sea Systems Command, 15 Dec 1987. Transfer is
accomplished via standard ship deck discharge-risers connected
by 2.5-inch (65-mm) flexible hose to standard pier risers (see
Figure 8). A ship nested outboard normally will lay hoses
across the deck of the inboard ship.
3.8.1.2
Ship Oily Wastewater Flows. Treatment systems should
be sized for the following flows. Ship bilge daily flow varies
with the class of ship, shipboard operations, and condition of
the ship's mechanical equipment. The three measures of ship's
flow are average (Qave), peak (Qpeak), and additional from
compensating fuel tanks (Qcomp). Estimated values for the ship
flow (without the use of onboard OWS) for each ship class is
listed on Table 12. These flows are used in various
combinations (depending on facility size) to estimate the total
daily oily waste flow (Qdaily) from a pier. Qcomp is determined
based on the fueling capability of the facility. If no fuel
capability exists on the pier, then this quantity is zero. Fuel
capability may be in the form of piping, trucks or barges. If
fueling capability exists, then this quantity is equal to the
maximum fueling rate for one day. Qdaily is used to estimate ship
utility charges and shoreside oily waste treatment plant
capacity, operating costs, and operating schedule. Plants
should normally be assumed to operate on a 40-hour work week.
The size of the pier facility depends on the historical and pier
berthing plan. Facility size and Qdaily are determined as per the
following subparagraphs.
