SAFE OPERATION AND MAINTENANCE OF DRY DOCK FACILITIES

Floating dry docks are often referred to as "floaters" - they are engineering structures having enough size, strong construction and displacement as well as sufficient stability to be able to lift vessels from the water using the buoyancy. The floating docks can normally be operated with list and trim to reduce block loading and reduce or, ideally, to eliminate ship stability problems when docking or undocking.

Some shipyards are equipped to transfer vessels to shore from a dock, which enables concurrent work on multiple vessels. The common construction of the docks implies a pontoon and wing walls. The pontoon is considered the major structural component of any FDD, i.e. floating dry dock, that shall be designed to provide due distribution of the concentrated blocking loads from the vessel to the docks deck and ultimately to the uniform buoyant force on the hull.

The pontoon provides the transverse strength for the dock as well as contributing to the longitudinal strength. Additionally, the pontoon must feature sufficient size to be capable of providing enough displacement to lift the ship together with the dock from the water. In short, this is must-have book for all shipyard specialists engaged in docking activities.

UNITOR — THE WELDING HANDBOOK FOR MARITIME WELDERS

A vessel at open sea fully depends on the professional knowledge, technical skills and also self-reliance of the crew members carrying out required maintenance and repair works. Among the other important technical skills that are considered necessary, we would mention the modern welding techniques.

The ultimate purpose of the present training handbook prepared by the specialists of the Unitor Company specifically for the maritime welders was to provide the welders engaged in different ship building and ship repair works with the useful source of practical knowledge covering the right solutions to the specific problems of the welding. The document opens with the quick introduction and guidance to the welding processes.

The process of welding and other related thermal processes are using compressed either compressed gas or electricity to get a concentrated heat source melting or burning away steel and other construction materials. All necessary safety precautions are required to be in place and followed in order to avoid any possible accidents relating to the supply of gas/electric power, sparks and fumes etc.

In the most countries, the regulations and guidelines relating to the welding and any other hot works together with their applications onboard vessels, are laid down by the authorities.
