Section 6 Routes to classification or hull certification

Parent topic: Chapter 1 Windfarm Service Vessels

6.1 General

6.1.1 There are two alternative routes offered by LR and for consideration by the Owner, Builder or Operator; these are the traditional full classification option, resulting in a class notation or the hull certification route. The choice of these options is driven by client requirements and by requirements of individual Flag and coastal state administrations. These two options are shown in Figure 1.6.1 Routes to classification or certification.

6.2 Classification

6.2.1 Classification covers the structural design, water tight integrity and standard of construction of the hull and construction, installation and testing of the propulsion machinery, essential auxiliary machinery, essential piping and electrical systems to the extent indicated in the Rules for Special Service Craft. A full classification notation consists of a hull notation and a machinery notation.

6.3 Hull certification

6.3.1 An alternative to full classification, hull certification is dependent upon and covers only the standard of construction, materials and workmanship of the hull as prescribed by Lloyd’s Register’s Rules and Regulations, and does not include machinery, piping and electrical aspects.

6.3.2 Hull certification, in general, only considers the welded construction of the hull and deckhouse and excludes appendages and closing appliances unless specifically requested. In most cases such appliances are type approved with third party certification.

6.3.3 LR hull certification satisfies the structural strength requirements of various statutory codes, for example MGN 280. For other statutory aspects of MGN 280 see Ch 1, 2.3 MCA Small Commercial Vessel and Pilot Boat Code of Practice (MGN 280)

6.4 Plan approval only

6.4.1 In many instances, Builders may wish to develop WFSV designs before marketing to potential customers. In these cases, LR is able to offer stand alone plan approval. This service may be extended to include survey under construction once a contract is signed with the Owner. This service may be applied to both classification and hull certification.
