Section 1 General

101. Definition

The deep tank is a tank used for carriage of water, fuel oil and other liquids, forming a part of the hull construction. The deep tanks used for carriage of oils are designated as "deep oil tanks", if necessary.

102. Application

1. Peak tank bulkheads and boundary bulkheads of deep tank(excluding the deep tanks for carriage of oil shaving a flash point 60 ℃ and below) are to be constructed in accordance with the require-

ments in this chapter. Where the bulkhead of deep tank partly serves as a watertight bulkhead, the part of the bulkhead is to be in accordance with the requirements in Ch 14.

2. The requirements in Ch 22 are to be applied to the bulkheads of the deep tanks for carriage of oils having a flash point 60 ℃ and below, in addition to those in this chapter.

103. Divisions in tanks

1. Deep tanks are to be of proper size and to be provided with such longitudinal watertight divisions as necessary to meet the requirements for stability of the barge in service conditions as well as while the tanks are being filled or discharged.

2. Tanks for fresh water or fuel oil or those which are not intended to be kept entirely filled in serv- ice conditions are to have additional divisions or deep wash plates as are necessary to minimize the dynamic forces acting on the structure.

3. Where it is impracticable to comply with the requirements in Par 2, the scantlings required in this chapter are to be properly increased.
