Tug boats

Description

The Council, as Statutory Harbour Authority has a requirement for the supply of one tug boat and/or design and build of up to two new tug boats which meet the Council’s specification, which are required to provide a safe and reliable towage service in the Scapa Flow (including Flotta Oil Terminal) and Kirkwall harbour areas and elsewhere.The existing fleet of three (3) tug boats (built 1989 and 1992) requires to be replaced as part of a planned programme in order to provide towage to the Flotta Oil Terminal, Scapa Flow and Kirkwall and to meet increasing demands and specification requirements within and beyond Orkney for towage. With a modern design vessel it is expected that greater operational safety margins, flexibility and efficiencies will be achieved. Lot 1: The provision (design and build contract) of one new build tug to meet the Council’s specification, this may include a new build tug that is currently under construction/constructed but unused with a contract duration and delivery timescale following successful sea trials, of between 6 months and 12 months with an option to extend for a further 6 months. The Vessel is to be designed primarily to carry out complex harbour towage duties but must meet all of the details as indicated in the principle dimensions and specifications stated below. The Owner of the vessel will be Orkney Islands Council, operated through Marine Services based in the Harbour Authority Building, Scapa, Orkney KW15 1SD, Scotland. The Specification is given as a guide as to the specific requirements of the Owner. Principle dimensions and specifications Length overall in the region of 32 metres Breadth extreme 12 to 14 metres Operating draught maximum of 5.50metres (navigational draft) when fully loaded with fuel and fresh water Fuel capacity minimum of 120 cubic metres Fresh water capacity minimum of 14 cubic metres Class constructed to Lloyds Register survey, delivered in Class (LR) at least to the following: +100A1 Escort Tug UMS +LMC Firefighting 1, with water spray *IWS GRT Should be less than 500 These principle dimensions and specifications can vary to suit the ship builder’s final design as long as the requirements of the specification are met – although it is not expected that there will be large differences to the details stated. Lot 2 The provision (design and build) of two new-build tug boats to meet the Council’s specification as detailed in Lot 1. The first tug is to be delivered subject to successful sea trials in the initial 14 months period of the Contract with the second tug delivered in the second 12 month extension period subject to the Council taking up the option, subject to availability of funding for the supply of a second tug boat. A break point in the Contract will be established at which point the decision will be made by the Council to take up the option to extend the contract by a further 1 x 12 months, there will be a further option to extend the contract by 1 x 6 months to take account of any unforeseen delays.
