Scotland based MacDuff Ship Design reports it has had another busy summer and autumn with the delivery of a number of new vessels, work continuing on existing contracts and several new design contracts won. Alongside this has seen the continuation of the companies bureau work in naval architectural consultancy and the steady expansion of MacDuff Marine Surveyors.

25.5m Aquaculture Support Vessel for Inverlussa Marine Services
A new 25.5m Aquaculture Support Vessel has entered service on the West Coast of Scotland having been delivered in September 2017 to owners Inverlussa Marine Services. Built by Havyard Shipyard in Norway to plans by MacDuff Ship Design, the vessel is designed to support the fish farm sector and can also perform multi-role tasks such as mooring work and towing. The Kiera Fiona, as she is named, boasts two cranes of 48 metric ton/m at 18.5m outreach and 100 metric ton/m at 22m outreach respectively. With a beam of 9.7m and depth of 3.50m, the vessel is capable of carrying four 20 foot containers on deck or a total of 163 metric tons of deck cargo.
Kiera Fiona is the fourth vessel that MacDuff have designed for Inverlussa. She is a modified version of the Gina Mary completed earlier this year, and boasts a lifted wheelhouse to gain a skippers cabin in a full tween deck between focsle and wheelhouse, along with an extra 500mm lengthened section amidships to gain an increase in main deck area.
The engine room is fitted with twin 600HP at 1,800rpm Caterpillar C18 main engines are installed, driving fixed pitch propellers in nozzles through ZF W650 gearboxes. Auxilliary power is provided a Caterpillar C12 engine a Volvo D7 genset and Cat C4.4 genset.
12.75m Pilot Vessel for ABP Port of Ayr
MacDuff Ship Design also  announced successful trials and delivery of a 12.75m Pilot Vessel to owner Associated British Ports Ltd, Ayr. The vessel was ordered as a design build contract with MacDuff Shipyards winning the competitive tender. They contracted MacDuff Ship Design to produce the vessel design and steel kit to the owner’s strict requirements.
Stuart Cresswell, ABP Ayr and Troon Port Manager, said, “We are pleased to take delivery of this brand new vessel, which has been specifically designed to undertake a dual purpose role of delivering pilotage services and assisting the berthing of larger vessels in poor weather conditions. With the trend towards ever bigger ships, its arrival will help cement both Ayr and Troon’s status as primary hubs for trade in the West of Scotland and Troon’s long standing reputation as a Port of refuge for all shipping during bad weather” 
The vessel is designed as the primary vessel for the Port of Ayr and as such it was important that the vessel not only performed full pilot duties but also had capability to assist vessel when entering the port. With these varying requirements the vessel needed to be suitably robust for general harbor duties whilst maintaining strict weight management. At 12.75 meters length overall 4.5 meters beam and design draught of 1.2m, the vessel is designed to carry two crew and two pilots and operate between the ports of Ayr and Troon and the Scottish West Coast. The vessel is classed to MCA workboat code regulations and surveyed by SCMS. The propulsion machinery includes two John Deere 6068SFM85 engines rated 321 HP at 2600 RPM coupled to a ZF 305-3A gearbox with 2.423:1 ratio all supplied by E.P.Barrus. The vessel carries 4,000 liters of oil fuel and 210 liters of fresh water.
The hull form was based on a previous successful semi displacement hull form developed by MacDuff Ship Design for use in similar operations. This was tailored in the final design stages and to optimize performance and seakeeping whilst maintaining its workboat capabilities. MacDuff Ship Design provided full construction and outfitting drawings to MacDuff Shipyards, who completed the vessel on schedule with delivery to the port of Ayr slightly ahead of contract.
During sea trials, the vessels performed admirably, exceeding all expectations. The trials gave an improvement on both the predicted speed, reaching 12.2 knots at 100 percent MCR, and bollard pull, achieving 5.2 metric tons.
Fishing Vessel Deliveries
Along with these vessels we have also seen the delivery of four new fishing vessels all built by MacDuff Shipyards with designs being developed in cooperation between MacDuff Ship Design and shipyard. The vessels ranging in size from 19m to 29m have all proven to be excellent vessels with new developments in sea keeping and propulsive efficiency proving their worth.
New Designs and New Customers
MacDuff Ship Design also recently signed two new contracts for new design vessels.
MacDuff recently signed a contract to develop a new design 14m workboat with Cheoy Lee Shipyard. The contract is for a multipurpose vessel with capability for line handling and harbor tug duties. The design is targeted at multi disciplines within the same design envelope to allow variation in production to suit owner specification.
The second contract is with MMS Ship Repair & Dry Dock to design a 55 foot Trawler Yacht. The design is being developed in cooperation between the two companies with production of the first vessel scheduled to start early 2017. The design is to be certified under the recreational craft directive, a first for MacDuff Ship Design. The designer is currently in the process of finalizing initial design details prior to development of steel cutting data for the whole vessel.
