Descriptions

This notice seeks expressions of interest from economic operators experienced in fibre reinforced plastic/polymer commercial vessels construction to the current version of the UK Maritime and Coastguard Agency (MCA) ‘The Workboat Code’ (brown), Small craft codes — Publications — Gov.uk as amended, and capable of meeting the contracting entity's qualification requirements, as set out in this notice. This notice calls for tenders, for the build of 2 vessels, from those boat builders identified by the contracting entity as qualifying and invited to tender. The purpose of the contract is the build and delivery to Denton Wharf, Gravesend, UK of 2 vessels built sharing the same hull design. The first being a Vessel Traffic Control Launch and the Second being a Commercial Dive Support Boat. The hull design will be a Catamaran with length overall of no less than 13m and no more than 16m and a beam overall of between 5m and 6m but no more than 6m. Propulsion will be via standard propeller shafts and screw propellers driven by marine diesel inboard engines (Diesel Hybrid systems will be considered) such as those manufactured by John Deere, Volvo or Scania (or equivalent). The vessels must have a maximum continuous speed of 20 knots and a cruising speed of 15 knots. The hull form and hydrodynamic characteristics, ideally displacement or semi-displacement and low wash, must allow for operation in sea area 3 (up to 20 nautical miles from a safe haven) with acceleration at the helm position, in such state, of no more than 0.8g. However, the hull and weather deck shall be constructed to a sufficient strength standard for operation in sea area 2 (up to 60 nautical miles from a safe haven). A maximum water draft of 1.2m and the maximum air draft (mast lowered) of 3.5m. Further details will be given in separate specifications, 1 for each boat.
