Port Towage Lisbon "Sirios" – Schiffswerft und Maschinenfabrik Max Sieghold


Tugboat operated by Port Towage Lisbon seen on the Tejo River, Lisboa, in September 2019. This tugboat, named "Sirios" and registered LX-127-RC, is built in Germany by Schiffswerft und Maschinenfabrik Max Sieghold (Bremerhaven), completed in 1977, yard number 178, and originally delivered to Bugsier Reederei  (Hamburg) ¹ under the name "Bugsier 12". Steel hull and superstructure. It has an overall length of 87.3 ft and is re-equipped with two 1040 kW (1394 hp) ² Mitsubishi Marine S12R-Z3MPTAW main engines and Veth VZ-1250 "Z"-drive azimuth thrusters, providing a tractive effort ³ of 40 tons. Top speed is 12 knots. Port Towage Lisbon ⁴, whose name is usually abbreviated to PTL, is a Portuguese-Dutch partnership, bringing together REBONAVE (Setúbal) and Iskes Towage & Salvage (IJmuiden). Established in 2016 and based in Setúbal, PTL provides towage services and maritime assistance in the Port of Lisboa. The fleet includes tugs from both partners. Here, we see the "Sirios" (IT&S) on the Tejo River off Lisboa, prepared for a docking maneuver. Nearby, but not visible in this image, is the small tug "Alerta" (56 ft, 324 kW/435 hp) of Resistência (Grupo Lutamar). In the background, the container ship "Safmarine Nakuru". In 2021, Iskes Towage & Salvage is integrated into the Boluda Group, based in Valencia, Spain. In 2022, the "Sirios" is renamed "BV Sirios" and as far as I know it is currently operating in the Mediterranean.

As a note of interest, in Mitsubishi Marine terminology the designation "S12R-Z3MPTAW" denotes an R-series engine (R) with 12 cylinders (12) and conforming to "EU NRMM Stage IIIA Inland Waterway Vessel engines, category V1 :4" (Z3). The particle "MPTAW" describes the supercharging system, in this case benefiting from a cooling circuit with separation of high and low temperature and with the turbocharging air cooled by a closed system of fresh water controlled by thermostat. Engine made in Japan in Sagamihara (S). ●

Como nota de interesse, na terminologia da Mitsubishi Marine a designação "S12R-Z3MPTAW" revela um motor da série R (R) com 12 cilindros (12) e em conformidade com as normas "EU NRMM Stage IIIA Inland Waterway Vessel engines, category V1:4" (Z3). A partícula "MPTAW" descreve o sistema de sobrealimentação, neste caso beneficiando de um circuito de refrigeração com separação de alta e baixa temperatura e com o ar da turboalimentação refrigerado por sistema fechado de água doce controlado por termóstato. Motor fabricado no Japão em Sagamihara (S). ●

The tugboats "Sirios" and "Alerta" on the Tejo River off Lisboa. ● Os rebocadores "Sirios" e "Alerta" no Rio Tejo ao largo de Lisboa. 



No início de mais um dia, o rio é sempre um lugar movimentado. Enquanto a jusante os rebocadores "Sirios" e "Alerta" preparam mais uma manobra, a pouca distância o "Sintrense" atravessa o Tejo, carregado, rumo a Lisboa, que desperta sob a cálida e misteriosa luz de Outono. No Cais do Sodré, o "S. Julião" juntar-se-á em breve às silhuetas difusas sobre a hipnótica tremulina a montante. O início de mais um dia, único, como todos os outros dias. ●

Despite its historical value, the place it occupies in the hearts of successive generations of commuters and with a robustness and reliability that have not been surpassed by more recent constructions, it was not possible to keep the fe...

Back to Normality

Image
After the disastrous choice of the British operator VODAFONE as my internet provider , which sent my connectivity back into the dark ages and whose mediocre or non-existent service affected five months of publications (September, October, November, December and January), it is finally possible to bypass the obstacle with the support of an interested party. The return to normality should occur from February 20th, closing with sixteen publications the cycle dedicated to passenger vessels in regular or tourist service on the Tejo River. As a note of interest, partly motivated by this disastrous experience with the British operator VODAFONE, I will soon launch a new digital space –  UNPLEASANT | LX . It will be interesting. By the way, the problem reported to the operator VODAFONE in August 2023 is still unsolved in February March April October November 2024 . Literally, unbelievable . As I wrote in one of several texts published on social media and made known in Berkshire, «[…] ...
