Tug Use in Port. A Practical Guide/Использование буксиров в порту. Практическое руководство

Издание на английском языке
One of the most delicate responsibilities of pilots occurs during berthing and unberthing operations. Carefully berthing a ship, often after a long pilotage mission, is almost a work of art. Of critical assistance in this task is the support of tugs and their skippers. Today, this is probably true more than ever, as ships become ever larger, e.g., ultra large container vessels with their huge windage, while often being significantly less powerful or able to manoeuvre themselves in confined waters. These vessels may have proportionately smaller rudders coupled with engines that, often deliver less power, notably as a result of software-managed fuel consumption.
