In accordance with SOLAS Reg.II-1/12.5.1, the collision bulkhead may be pierced below the bulkhead deck by not more than one pipe for dealing with fluid in the forepeak tank provided that the pipe is fitted with a valve capable of being operated from above the bulkhead deck. 4. Further, in SOLAS Reg.XII/13.1, if the location of such valve controls complies with all requirements of SOLAS Reg.XII/13, it could be accepted as an alternative to the valve control specified in regulation SOLAS Reg.II-1/12. In order to satisfy these requirements, the valve should be capable of being brought into operation from a readily accessible enclosed space, the location of which is accessible from the navigation bridge or propulsion machinery control position without traversing exposed freeboard or superstructure decks 5. While discussing the above, it was confirmed by the Panel that the location of the hydraulic quick connect within the engine room located below freeboard deck would be acceptable. Local hand powered valve operation from above the freeboard deck is not necessary provided the arrangement fully complies with SOLAS Reg.XII/13. 6. Therefore, it was agreed by the Panel to amend paragraph 2.4 of UI SC179 and for clarification five(5) typical examples of arrangement that were collected from various actual applications are included in this TB. < CASE #1 >

1. The remote control valve (V1) is located in front of the collision bulkhead and can be remotely controlled from the BCR or ECR. 2. The remote control valve (V1) also can be manually operated from the bosun store above freeboard deck by using a hydraulic hand pump. < CASE #2 >

1. The remote control valve (V1) is located in front of the collision bulkhead and can be remotely controlled from the BCR or ECR. 2. The remote control valve (V1) also can be manually operated from the exposed freeboard deck, outside the bosun store and apart from the collision bulkhead, by using a hydraulic hand pump. < CASE #3 >

1. The remote control valve (V1) is located in front of the collision bulkhead and can be remotely controlled from the BCR or ECR. 2. The remote control valve (V1) also can be manually operated from the bosun store above freeboard deck by disconnecting the electric actuator (extended spindle). < CASE #4 >

1. The remote control valve (V1) is located in front of the collision bulkhead and can be remotely controlled from the BCR. 2. The remote control valve (V1) also can be manually operated from the hydraulic power pack located in a readily accessible enclosed space above freeboard deck by using a hydraulic hand pump. < CASE #5 >

1. The remote control valve (V1) is located in front of the collision bulkhead and can be remotely controlled from the BCR or ECR. 2. The remote control valve (V1) also can be manually operated from the hydraulic power pack located in a engine room which is considered to be a readily accessible enclosed space below the freeboard deck by using a hydraulic hand pump. However, this arrangement is not acceptable because of the collision bulkhead penetration of hydraulic piping which is in conflict with the requirements of SOLAS Reg. II-1/12.5.1 allowing the piercing by not more than one pipe for dealing with fluid in the forepeak tank.
