SECTION 1- GENERAL

100. Intent & Definition This specification is intended to describe the construction of a twin screw Anchor Handling, Towing, Supply and fire fighting Vessel (AHTSV) completely outfitted and equipped for rescue, offshore supply and other related duties. The Vessel will be classed for Unrestricted Service.

The Anchor Handling Tug Supply Vessel is to tow, supply, support and act in the capacity of a safety vessel for offshore drilling and work-over rigs in the operational areas on a twenty-four (24) hour per day basis. Vessel shall be capable of operating in all seas and weather conditions, which may occur. Vessel may be utilized for any duties within the capabilities of the vessel The Vessel shall be equipped with two (2) Controllable Pitch Propeller, one (l) stern thruster and two (2) bow thrusters or Controllable pitch Azimuth Thruster and two (2) bow thrusters . The Vessel may be of single hull but to have double skin in way of the E/R. All accommodation and wheelhouse shall be forward and an open flat deck area aft for deck cargoes. For further details see the relevant sections of this Specification. While most of the functions and equipment requirements have been indicated herein after but it may not be exhaustive. Hence any item or equipment essentially required to proficiently utilise this type and size of vessel shall be provided by the builder, irrespective of whether or not the same are specifically detailed in this specification. The builder will ensure the safe and effective operation of all the systems, equipment and machinery provided on board, by providing suitable guards, platforms, accesses, communication facility, clear visibility, tools or any other accessories as required for satisfactory operation. Charter party specification requirements for the scope of service for this vessel, as annexed, are to be complied with, if not included this specification.

With respect to surface preparation the following standards shall be applied:

SIS 055900 - Svensk Standard.



All surfaces shall be surveyed by Owner’s, Builder’s and paint manufacturer’s surveyors before starting painting, between each paint coat and after finishing painting. The Owner’s and paint manufacturer’s representatives shall have the right to inspect and report on the standard of surface preparation and quality of coatings at all stages of application, and to request corrective measures should deviations from either the specification or good practice be discovered.
