Guide for the Optional Class Notation Deep Water Anchoring for Oil Tankers and Bulk Carriers (DWA)/Руководство по условному обозначению класса постановки на якорь нефтяных танкеров и сухогрузов

Книга на английском языке.
In many instances the increase in the number and size of oil tankers and bulk carriers has out paced the ability of ports to provide sheltered anchorage locations for these vessels. As a consequence, there has been a growing need for owners, operators and the vessel’s crew to anchor these vessels outside a harbor or similar areas of sheltered water. Noting the need to provide these same owners, operators and vessel crews, as well as designers and equipment providers, with a guide to assess the adequacy of anchoring equipment, ABS has, in response to requests from our clients, developed this Guide.
This Guide specifies the ABS requirements and criteria for obtaining the optional class notation Deep Water Anchoring (DWA). Included within this Guide are requirements detailing the anchor size, chain length and size, and windlass particulars considered necessary to withstand the environmental conditions that vessels anchoring outside a harbor or similar areas of sheltered water may be exposed to.
