Tug is the most up to date advancement of the very effective Ridges 2400-SX layout
Turkey’s Sanmar Shipyards has actually supplied the Bo ğaçay XXXVIII, its 200th pull developed to a style byRobert Allan Ltd The distribution notes both a landmark in a functioning partnership of 25 years and also an additional advancement in pull innovation.
The Bo ğaçay XXXVIII is the most up to date advancement of the very effective Ridges 2400-SX layout and also integrates the recently created Caterpillar Advanced Variable Drive (AVD) hydro-mechanical crossbreed propulsion system.
BLOSSOM POWER
The pull is signing up with Sanmar’s very own towage fleet in Izmit Bay, Turkey, where it will certainly not go undetected. It has actually been repainted with an intense environment-friendly hull and also vivid blossoms on the deckhouse motivated by pop musician Andy Warhol’s “Flowers” print. Sanmar claims the paint work is “reflective of the changing trend towards reduced environmental impact from tugs” and also “is bound to attract much attention in the usually moribund world of tugboat aesthetics!”
Particulars of the brand-new pull are as adheres to:
- Length total: 24.40 m
- Beam, formed: 11.25 m
- Depth, formed: 4.38 m
- Maximum draft: 5.40 m
The vessel is classified by ABDOMINAL with the symbols:
✠ A1, HAULING VESSEL, ✠ AMS, ✠ ABCU, UWILD, QR, UNRESTRICTED SOLUTION, BP (70 tonnes)
Tank capabilities are:
- Fuel oil: 72.4 cu.m
- Fresh water: 10.8 cu.m
- Fi-Fi foam: 6.6 cu.m
PET CAT AVD SYSTEM
The PET CAT AVD system includes a set of double input, continually variable transmissions, situated in the shaftlines in between the major engines and also the Z-drives. The AVDs can approve power from the PET CAT 3512 major engines, ranked at 1,765 kW at 1,800 rpm, and/or from 2 435 kW hydraulic electric motors powered by a solitary PET CAT C32 complementary engine, ranked at 1,081 kW at 2100 rpm. The power is supplied to 2 PET CAT MTA 627 FP Z-drive systems with 2.7 meter size repaired pitch props.
A main benefit of the PET CAT AVD system is the continually variable transmission which can regulate prop speed up to 0 rpm like a sliding clutch. It can likewise rotate the prop up faster than would certainly be feasible if the engine was straight paired to the drive, enabling the engines to run in their peak performance area rather than running along the prop need contour at greater certain gas oil intake, hence causing substantial gas financial savings.
With a dealt with pitch prop pitched for bollard problem at 0 knots, complete power can be drawn from the engine when cost-free operating, just like a manageable pitch or diesel electrical system.
In words of Nathan Kelly, Caterpillar Marine Product Definition Engineer: “This (AVD system) allows propeller speed independent of engine speed so optimal engine efficiency can be achieved leading to fuel savings of fifteen to twenty percent. Basically, all the benefits of a variable speed Diesel Electric Propulsion (DEP) system at a fraction of the cost and size.”
Other benefits consist of boosted feedback and also velocity in addition to reduced total upkeep prices as a result of considerably minimized running hrs on the major engines.
Notably, with this system the engines are smaller sized than would generally hold true in a yank of this power (3512 vs. 3516 engines). The added power to attain optimal bollard pull originates from the C32 engine that likewise drives the Fi-Fi pump. The equipment setup and also power circulation circumstances for the 4 operating settings are highlighted listed below:
HAULING EQUIPMENT
Towing equipment includes;
- DMT Type TW-E 250KN electrical dual drum hawser winch with a pull of 250 kN at 0– 9 meters/minute on reduced rate and also 80 kN at 0– 28 meters/minute over rate
- Data Hidrolik tow hook
- Data Hidrolik 5 tonne aft capstan
CLOTHING
The vessel has actually been furnished to Sanmar’s typical really high criteria for a staff of 6 individuals. The major deckhouse includes the galley, mess, 2 police officer cabins, and also an usual WC. The reduced deck includes 2 dual berth cabins, a washing, galley shops, and also an usual WC room. The wheelhouse gives all rounded optimum exposure and also phenomenal exposure to the bow and also side fendering. The engine area includes a tiny, audio immune switchboard area.
On tests, Bo ğaçay XXXVIII accomplished 70.35 tonnes bollard pull and also a complimentary running rate of 13.3 knots.
