tional requirement for an unobstructed stern area for cargo handling in offshore environments, as well as for duties such as anchor handling and towing, this is simply not practical for OSVs. With respect to navigation bridge visibility, SOLAS Regulation V/22 requires vessels to comply with specific requirements with regards to their navigation bridge deck layout and arrangement. In particular, the ship's sides are to be visible from the bridge wings. Because of the particular nature of their operations, most offshore support vessels do not have bridge wings but have a set-in wheelhouse configuration. The International Convention of Load Lines 1966 requires the existence of guardrails or bulwarks to be fitted on exposed decks for crew protection. As previously noted, anchor handling and towing operations require the stern area of these vessels to be open, making it impractical to have permanent fixtures such as guard rails or bulwarks. The strongest SOLAS Regulation II-1/12-1 requires double bottoms to be fitted for vessels as far as practicable. OSV designs tend to have streamlined hull forms and a large More sizes of stainless steel skeg to improve maneuverability and cable ties and banding than towing function. As a result, designers anyone in the industry. More are often hard pressed to fit double botcorrosion resistance. More toms under the engine room due to the holding strength.
