Section 5 Lifting appliances, equipment integration and foundations

5.1.1 Where the vessel has fitted onboard lifting appliances, which are considered by LR to be essential for the vessel to fulfil its primary operational role, and if there are no alternative means of operation, it is a requirement that the lifting appliance(s) is classed in accordance with the requirements of the LA or notation, see Pt 3, Ch 9, 6 Lifting appliances and support arrangements.

• Where the LA notation is assigned,the lifting appliance(s) are to be designed, built and surveyed in accordance with LR’s Code for Lifting Appliances in a Marine Environment, July 2022.
• Where the notation is assigned, the lifting appliance(s) have been classed by a recognised classification society other than Lloyd’s Register and later transferred into class with LR. In such cases, a new Register of Ship’s Lifting Appliances & Cargo Handling Gear (LA.1) will be issued in accordance with LR’s Code for Lifting Appliances in a Marine Environment, July 2022. From the time the notation is assigned, the subject appliance(s) is to be tested and surveyed in accordance with LR’s Code for Lifting Appliances in a Marine Environment, July 2022.

A lifting appliance forms an essential feature of a vessel if the purpose of the vessel is predominantly to support the appliance, and the purpose of the floating structure is impaired if the appliance is not functioning.

5.1.2 For non-classed lifting appliances, generally it is a requirement of National Authorities that lifting appliances are approved, examined, tested and certified by a competent person or organisation. It is LR’s interpretation of the intention of current National Regulations that every lifting appliance is to be certified. See also Pt 3, Ch 9, 6 Lifting appliances and support arrangements.
