2. Purpose

This document sets the Maximum Permissible Tension (MPT) for the stern A-Frame installed onboard the vessel R/V Sikuliaq in accordance with the UNOLS Research Vessel Safety Standards (RVSS), Appendix B.

The tension member employed in the system is considered a component of the entire handling system and shall be used in accordance with Appendix A. The normal breaking load (NBL) of the tension member shall be less than the MPT with exceptions as outlined in RVSS Appendix B, Section B.4.

Associated MCDs for this component are:

Port Flag Bock Starboard Flag Block Underdeck Winches Additional wet gear rigging to be added as necessary

2.1. Deployment Types

This stern frame will potentially be used for the following types of deployments:

Towing – Surface Y

Towing – Mid-Water Y

Towing – Deep Water Y

Station Keeping – Surface Y

Station Keeping – Mid-Water Y

Station Keeping – Deep Water Y

See Reference 3.2.3, Section B.3.5 for descriptions of operations

3. General

3.1. Description and Limitations

This document is developed for the captain and crew of the R/V Sikuliaq to provide guidance on the acceptable loading conditions for the stern A-Frame. Due to the complex nature of oceangoing research and the highly variable loading conditions that may be encountered, a number of assumptions were made in order to develop this general purpose tool:

1. The maximum permissible tensions (MPT) are valid with the A-Frame resting in either of its two aft stop positions. Caution is advised for luffing operations near the limit of the padeye MPTs, as line tension held by winches located on the aft Main Deck can result in A-Frame overloading.

2. The geometry angles are defined per Section 4. All calculations were performed assuming zero initial heel and list. Any initial heel and list needs to be accounted for when monitoring the loaded cable angle into the water.

3. Vessel stability was not evaluated for any load cases; it is incumbent upon the captain and crew to insure that adequate stability exists in all loading conditions to conduct operations safely using the following permissible tensions.

4. The calculations were performed assuming relative motions and accelerations as defined below. It is incumbent on the ship’s captain to determine whether operations should continue based on ship’s motions in a seaway.

5. Two primary load cases are analyzed: station keeping and towing.

a. Station keeping load cases assume that the vertical or side angles into the water may be up to 30 degrees from the vertical. These assumptions account for the combined effects of ship and overboard package relative motions.

b. Towing load cases assume a vertical angle of 45 degrees and side angles of 30 degrees to port or starboard.

6. Since the A-Frame capabilities are inextricably linked to its structural condition, the Owner of the vessel is responsible for maintaining the A-Frame to the manufacturer’s specification.

7. The A-Frame’s hydraulic cylinders are the only mechanisms for resisting reaction vector forward components. Extra care is required when operating with cable leads forward of vertical because of this resultant forward vector. Should hydraulics fail during operations of this type, the A-Frame will rotate forward outboard till it hits the hard stops.

8. Maximum permissible tensions are calculated assuming that there is only a single load on the A-Frame at one time and the cable lead from the winch does not cross the vessel centerline. Portable winch load cases are symmetric about the centerline although only one side is shown.

9. The portable deck winches are assumed to have a levelwind lead 11" above the aft Main Deck. This is conservative for stern A-Frame loading and the assigned load case MPT is applicable to levelwind leads higher off the deck for that winch position.

R/V Sikuliaq MCD – Stern A-Frame and Foundation, Rev.C

10. For intermediate deck winch positions, reference the load case winch position further aft of the position in question for the applicable MPT.

11. For all heavy operations such as towing or coring where the cable tension will approach the MPT of the Stern A-Frame, the A-Frame must be positioned at one of the two

outboard stop positions. Primary supported by the cylinders and a Secondary by bearing against the structural hard stop.
