7iacs And Solas Requirements
7.1 Existing Bulk Carriers
To reduce the risk of failure in older ships, IACS introduced new Unified Requirements to reduce the risk of progressive flooding in existing bulk carriers. To prevent progressive flooding due to sea water in No. 1 Hold, the corrugated transverse bulkhead between the first two cargo holds, and the double bottom in way of the first cargo hold had to comply with new strength requirements assuming that No. 1 cargo hold was flooded. A damage stability review had to be performed with No. 1 Hold flooded, and more frequent and close-up surveys of critical areas such as side frames and side shell had to be made.
7.2 New Single Side Skin Bulk Carriers
The IACS requirements for new single side skin bulk carriers address the following structural areas:
• increased requirements for the strength of side frames
• longitudinal strength of vessel to withstand any hold being flooded
• transverse watertight corrugated bulkhead strengths of all cargo holds to withstand hold flooding
• double bottom strength to withstand hold flooding
• increased strength requirements for hatch covers in forward holds
7.3 SOLAS Regulations
At a SOLAS Conference held at IMO, in November 1997, a new Chapter XII on bulk carriers was added in SOLAS. The regulations/requirements are essentially similar to the IACS requirements. Compliance with IACS requirements is also required.
