Sanmar's 100th Tug Breaks New Ground!

Sanmar, Turkey’s renowned builder of sophisticated tugs has reached the significant milestone of its 100th tug completion with a new exclusive ASD design from leading naval architects, Robert Allan Ltd to further broaden its customer options. Having experience as both builder and international tug operator, Sanmar approached RAL with proposals to enhance the performance of the standard RAmparts 2500 and the result is the 2400SX (Sanmar eXclusive) which the builder is calling its Bogacay Class. This translates into English loosely as ‘bull stream’. Bogacay 1 is to be renamed Zeycan Y and will operate in Gemport, Turkey.
Confirmed Robert Allan: “This new Sanmar 2400SX project is a customised version of our RAmparts 2500 design, updated for Sanmar’s production and marketing objectives, and incorporating, as always, some of their well-thought out ideas about how to build better tugboats. This design is capable of accommodating power sufficient to develop 70 tonnes bollard pull, and is under the SOLAS rule length of 24m.
“The hull form of this new design is typical of most of the RAmparts Class designs, with good dead rise for improved thruster performance, modest side flare and a half-raised forecastle deck for good sea keeping, gently rounded deck line in plan to ensure that the tug can safely and easily come alongside and remove itself from an attended ship at speed, and most importantly the characteristic conically shaped chined stern unique to all Robert Allan Ltd designs, which ensures that the tug can run astern at high speeds and maintain good control and directional stability.” There are two powerful variants within the new class to give bollard pulls of 60 or 70 tonnes depending on the propulsion machinery size selected by the customer. However, this first of Class utilises a pair of powerful 1765kW Caterpillar type 3512C main diesels turning Rolls-Royce model US 205FP Z-drives to give a bollard pull in excess of 60 tonnes and a free-running speed of 12 knots. One new aspect of the design appropriate to all of the Class is a beamier hull shape. At 11.25m, this 2m increase in beam over the LOA dimension of 24.40m will offer greater stability.
Generally, the RAmparts 2400 SX is a robust, all-welded steel construction with scantlings significantly in excess of the minimums of any Classification Society but specifically Zeycan Y has been constructed to meet the requirements of the American Bureau of Shipping. Although the Bogacay Class can be fitted with a FiFi1 system, this first vessel has a main engine driven single foam water monitor system furnished by FFS to what is often referred to as FiFi 1/2.
The accommodation layout of the new vessel has been developed to match the most commonly acceptable manning standards with two single officer cabins on the main deck and two twin berth crew cabins below. The galley and mess/lounge are on the starboard side of main deck. Other operators with different requirements may select layouts ranging from the classic ‘day boat’ through to full accommodation for a crew of up to six. This first vessel has been fitted with a double drum DMT winch forward, Data Hidrolic tow hook and capstan aft and a very comprehensive electronics package from Simrad, Furuno and Sailor.
