DNV DNV-ST-0377 PDF

This standard covers the design, materials, fabrication, installation, testing and commissioning of shipboard lifting appliances and industrial lifting appliances. The categorization of lifting appliances is based on installation and intended function for the lifting appliance:

a) Shipboard lifting appliances:

— lifting appliances on board ships intended for load handling within and outside ships while in the harbour and within ships while at sea.

b) Industrial lifting appliances:

— lifting appliances onshore and offshore, not covered by a) or DNV-ST-0378.

Guidance note:

The main purpose of the lifting appliance will define the category of the lifting appliance and relevant applicable standard. Hose handling cranes are considered as shipboard lifting appliances and are covered by this standard. This includes hose handling operations at sea. Alternatively, on customer's request, hose handling cranes may be certified according to DNV-ST-0378.

Each lifting appliance has its separate intended functions. Examples of intended functions are, but not limited to:

— loading and discharging of ships

— handling of provision, store and spare parts, cargo hoses, gangways and ammunition

— handling of Suez canal boats and search lights

— conveyance of persons/personnel

— handling of ramps and moveable cargo decks etc.

Requirements presented herein are minimum requirements to be satisfied, although subject to acceptance by the Society, other minimum requirements may be agreed e.g. based on new technology available at the time of application for certification.

The requirements of this standard may be supplemented with additional requirements where installation of specific design or assessment shows that standards that provide equivalent or higher level of integrity and safety are more appropriate.

The standard consists of a three level hierarchy of documents:

— Sec.1 and Sec.2 provide principles and procedures of the Society's classification, certification, verification and consultancy services.

— Sec.3 through Sec.13 provide technical provisions and acceptance criteria as well as the technical basis for the services stated in the first two sections.

— Appendices provide proven technology and sound engineering practice as well as guidance for the higher level documents mentioned in this document.

This standard distinguishes between:

— information and description of services

— requirements.

Consequently, these two subjects are separated, and the standard is divided into three parts:

— Sec.1 to Sec.2: General information, application, definitions and references. Description of applicable services and relations to rules and regulation from institutions other than the Society.

— Sec.3 to Sec.13: Requirements and technical provisions.

— Appendices.
