The second edition includes key purchaser information, such as rope size, rope performance and hawser assembly instructions. The packing of hawsers and rope dimensions are illustrated through detailed technical drawings. Each inspection process step is fully explained and supported by checklists and reports. The Appendices include new electronic checklists and forms which cover key definitions for rope design and quality assurance terminology.
