A SIMPLIFIED STABILITY LETTER FOR OFFSHORE SUPPLY VESSELS
This paper presents a simplified method for the preparation of stability information for Offshore Supply Vessels. The paper reviews the current methods used by the Eighth Coast Guard District Merchant Marine Technical Office for preparation of stability information and contrasts these to the proposed "simplified" method. The simplified stability letter incorporates a Loading Diagram which will make it easier for the vessel operator to use. The recommended simplified letter will allow designers to obtain a higher maximum amount of deck cargo, provide more flexibility in the manner which cargoes are carried, allow operators to exchange consumables for additional below deck cargo, and simplify the calculations necessary for preparation of the stability information. It should be cautioned that the method presented is only the opinion of the authors. Approval should be obtained from the cognizant Coast Guard technical office before employing this or any other proposed method. It should also be noted that the stability criteria presented in Appendix I is not yet included in regulations and is subject to change.
