-   Die André B

The Dutch tug owner Hubregtse discovered a possible niche market in Khazakstan in the late 1990ies. A need existed for shallow draught but powerfull tugs for supporting of engineering and offshore work. First tug in this market became the DUTCH PEARL in 1999. The most striking feature of the tug was the square, blunt looking superstructure. New slightly larger versions got the more rounded forms that are now typical for this series of tugs. Other tug owners got interestet in this series within the next years. One of these is the BMS (Bouwman Marine Service) Holding BV. The ninth and till now last tug in this series was built for this tug owner and named:

André B

-   Construction phase

The Bouwman Marine Service (BMS) Holding BV ordered the ANDRÉ-B on 12.04.2006 at the shipyard Gebr. Kooiman BV in Zwijndrecht, The Netherlands. The delivery was planned for end of March 2008. The design office of the Kooiman Shipyards, Kooiman Ontwerp en Adviesbureau, designed the tug in close cooperaition with the owners according to owner's specifications and supplied the engineering and technical support. Shipyard Hoebée in Dordrecht built the ANDRÉ-B. Shipyard Van Os in Yerseke provided the superstructure, the aluminium wheelhouse, and the mast. Both shipyards are part of the Kooiman group. The tug was launched on 9.03.2008. The yard trials were successfully completed on 1.04.2008. ANDRÉ-B was christened in her home port Zierikzee, The Netherlands, on 18.04.2008. The yard handed the tug over to the new owners the same day. ANDRÉ-B flies the colours of BMS Towing BV.

-   Description

General: ANDRÉ-B is a conventional tug with open stern for offshore work and anchor handling and able to take anchors on board. The stern is fitted with a push knee with a 800 mm cylindrical rubber fender supplied by Trelleborg Bakker. She has two propellers in fixed nozzles. Two fishtail-rudders are mounted behind each nozzle, in total four rudders. Port and starboard rudders can be operated independently. The rudder angle can be up to 75. The arrangement of the nozzles is somewhat unusual for a conventional tug. They are hanging free below the hull and extend approx. one meter below the bottom of the hull. This allows a larger propeller diameter ang gives a better water flow. This arrangement is more common in ASD-tugs. A heavy round strut is running from the bottom plates to the lower edge of the nozzle as protection against groundings. The double chine hull has flat strakes between the chines. Bilge keels are fitted between the chines. The bow is ice-strengthened and a longitudinal stringer provides extra protection against ice-damage. A steel fender runs around the hull. Additional protection comes from large rubber tyres. ANDRÉ-B is certified for world wide sailing. Two Mitsubishi 16-cylinder-Diesel engines Type S16R-MPTK provide power for propulsion. The engines have an output of 2x 1,250kW (2x 1,700bhp) at 1,600rpm. Each engine delivers the power through a Reintjes reversible reduction gearbox type WAF 763 with a ratio of 5.750:1 to the propellers. The propellers with a diameter of 2.10m were supplied by Van Voorden und run in nozzle type 37 of the same manufacturer. The tug has a maximum speed of 12.5kts and a maximum conzinous bollard pull of 47.7t. Tank capacities are: 120m3 fuel oil, 25m3 fresh water, sewage tank 7.5m3, lube oil 2.5m3, and dirty oil 2.2m3. ANDRÉ-B is equipped with a hydraulically driven Verhaar Omega VB-1100-330kW bow tunnel thruster with 330kW capacity. Two generator sets with Mitsubishi 6D16 diesel engines and Stamford alternators provide 71.5kVA each. A hydraulic set with a Mitsubishi diesel engine type S6A3 MPTK with 410kW (557hp) provides all needed hydraulic power.

Forecastle deck:

The forecastle deck is at the transition to the main deck raised approx. 1.15m. The deck carries a hydraulically driven combined anchor and mooring winch supplied by Kraaijeveld. The winch has two cable lifters for anchor chain with a diameter of 20.5mm, one drum for 20mm nylon mooring rope, and two warping heads. The anchor winch operates two "high holding power"-type anchors with a weight of minimum 430kg. The chains run through chain stoppers which are integrated into the winch foundation. Two guide rollers and an assortment of bollards make the anchor and mooring gear complete. Behind the anchor winch the superstructure is housing the galley, the mess, and a large sanitary space.

Tween deck:

The deck is located beneath the forecastle deck and accommodates the crew cabins. There are two single-bed cabins, each with sanitary space, for the captain and chief engineer. There are two more single-bed and two two-bed cabins with the sanitary space on forecastle deck. Accommodation and the complete superstructures are air-conditioned.


The hydraulically driven towing winch is mounted behind the superstructure between the two funnels with exhaust pipes and supply air shaft. The winch was supplied by Maaskant shipyard. It has two independently operated drums. Hydraulic motors and brakes were supplied by Hägglunds Drives. They are protected by a fibreglass cover. The maximum pulling power is 45t, the braking force 78t, both in the first layer. The speed is stepless controllable between 0 and 33m/min. The Hägglunds motors can be switched in a free wheeling mode with up to 600rpm. The two drums are of different length, 920mm and 520mm, and carry 700m respectively 400m steel wire with a diameter of 38mm. Two hydraulic coupling winches are placed between superstructure and towing winch. They can be used as tugger winches too. Behind the towing winch is the towing fairlead. The guiding areas are clad with stainless steel. The starboard post is designed as foundation for the crane and very massive. The crane is a knuckle boom crane make Heila (Marine Cranes) HLRM 200-4SL with a safe working load (SWL) of 9.5t at the maximum reach of 15.75m. The crane can be operated with a radio remote control unit. A Mampaey quick-release towing hook with a SWL of 15t is mounted to the port side post of the fairlead. In front of the port side post, a bit more to the bulwark, a capstan with a pull of 5t at 12m/min is mounted. Behind the posts of the fairlead horizontal sheeves are placed to guide the coupling wires. The afterdeck is wood clad between the towing fairlead and the wide stern roller. It has a free space of 120m2 and is equipped with fittings for two 20' containers. Two towing pins and one fork are placed in front of the stern roller. Two stop pins are installed at the sides of the rollers. All are hydraulically operated. They are supplied by WK Hydraulics and have a SWL of 30t, the same as the stern roller.

Tanktop deck:

Beneath the accommodation a store with shelves and cold storage with freezers is located. To the aft it is followed by the engine room. The room contains the main engines, generator sets, hydraulic set, an assortment of pumps, and a fresh water maker with an output of 3.5m3 in 24 hours. One of the gensets has an extra cooling radiator for use while in harbour. Next is a store and workshop area. The last compartment contains the hydraulics for the pins and fork as well as the rudder engines.

Bridge deck:

It is the next deck above the forecastle deck and carries the wheelhouse. The main control console is place in the front of the wheelhouse and is designed for one man operation. The console is U-shaped and accessible by a sliding pilot chair. Hands free communications were achieved by mounting goose neck microphones and foot switches. A second control console is provided in the aft of the wheelhouse overlooking the afterdeck. It is divided into two panels carrying the controls for rudders, engines, and winches. A spacious settee with table is placed at starboard beside and aft of the main control console, a communications console at the port side. The navigation equipment consists among others of two Japan Radio Co. (JRC) radars, one with ARPA-funktion (Automatic Radar Plotting Aid) and one river radar, echosounder, DGPS, gyrocompass Alphatron Minicourse, magnet compass by Cassens & Plath, satellite compass by JRC, two auto pilots, AIS system from JRC, and an Alphatron ECDIS- (Electronic Chart Display and Information System) chart system. The communication equipment is according to GMDSS- (Global Maritime Distress and Safety System) area A3 standard (world wide) and consists of the following equipment provided by Sailor: two VHF stations with DSC- (Digital Selective Calling) funktion, one MF/HF station, one VHF station for inland radio telephony, and two Inmersat-C stations. Additional a GMS cellular telephone, one Mini-M satellite telephone and a JRC Navtex-Receiver are provided.

Top deck:

on the top deck the magnet compass, a number of antennas, the navigation mast, and two 12-person inflatable life rafts are mounted. The mast carries the two radar antennas, two search lights, the navigation lights, and eight 1,000W flood lights at the top to give ample light for save working in the night. The mast can be tilted down above the lowest mounted radar antenna to reduce the airdraft.


ANDRÉ-B has a crew of five persons when on 24 hour duty. There are accommodations for a maximum of eight people.
